Good afternoon, dear visitors of our site. Many residents of our country are familiar with the situation when they have to resort to self-installation of gas equipment to heat their site.

This article will tell you about the main nuances of using gas cylinders in everyday life and will be useful to those who have not yet come across their purchase. We will also find out whether it makes sense to buy a new container and what you need to pay attention to when buying a used cylinder.

Among other things, in the article you can learn about the most important thing - how the filling of gas cylinders with propane takes place. Let's not waste time and begin to study this issue.

Types and features of gas storage cylinders

Usual gas bottle is a durable steel container. There are several common volumes: 5, 15, 25 and 50 liters. There are also cylinders made of polymeric materials, their volumes differ from common steel ones and often the volume of a composite gas cylinder with propane is 14 or 33 liters. Naturally, there are differences between iron and composite containers.

1. Steel cylinders are manufactured exclusively in the factory. In addition to the use of durable material, great attention is paid to the reliability of welds when creating. The better they are made, the longer the household cylinder will last. When buying a steel model, you should very carefully study the welding places and pay attention to whether the seams are processed. The main advantage of iron models is durability, but before buying, you should prepare a place for installing the container. If the room is enough high level humidity, the container may rust and deform over time.
2. More expensive and modern version - polymer container. It has a lot of positive aspects, but I would like to emphasize their main disadvantage right away: the price of a polymer one is 2-3 times higher than that of a similar steel container. In production, fiberglass is used, which is durable and light in weight. This is a clear plus, because it is easier and safer to transport LPG in such containers. Besides quality models are equipped with additional protection of the body.Accordingly, in case of a fall with an allowable height passport or a small impact, the body of the container will not deform. Such a propane gas cylinder can be near a fire, because resistance to high temperatures is usually provided.

The color of a gas bottle is a kind of marker showing what materials it is intended for. There are cylinders painted in the following colors:

• white with yellow lettering for acetylene;
• propane tanks are colored red.
• medical and conventional oxygen are stored in blue cylinders;
• hydrogen should be dark green;
• nitrous oxide should only be stored in gray containers with black elements.

For many people, the weight of a propane tank is important. Steel empty models, depending on the volume, weigh from 4 to 22 kg. So, the largest of the commercially available household cylinders is designed for 50 liters and weighs 44 kg when filled. Therefore, you should take care of the possibility of transporting the container to your site in advance.

There are certain standards for filling cylinders. To calculate how much gas you can refuel, you should divide its passport volume by 1.43.

For example, you have a standard 27 liter iron cylinder at your disposal. You can safely store and transport in it no more than 19 liters of propane. Excessive pressure may cause the safety valve of the container to fail and cause an explosion.

Purchase of a cylinder and necessary components

Propane storage tanks have a virtually unlimited life. The main condition is compliance with all operating standards, as well as storage and transportation conditions. You can save a little and buy a used propane cylinder, but you need to approach the purchase with the utmost care.

First you need to make a visual inspection of the case. You can safely refuse the offer if traces of poor-quality welding and serious dents are visible on it. Appearance can tell a lot about the conditions in which he was. Suspicion can be caused both by traces of fresh paint, and vice versa, too old cracked coating.

You should not risk buying a used container if there is even the slightest suspicion of rust. This indicates that the container was stored incorrectly, in high humidity conditions. Even a small speck of rust will sooner or later increase, which will inevitably lead to gas leakage, and in the worst case - to an explosion.

Should be ok inlet valve and a valve. If they are damaged or traces of repair are visible, then in the future they will require replacement, and, accordingly, additional costs.

The points described above must be taken into account when buying a new cylinder, since no one can guarantee that the correct conditions were observed during storage in the warehouse.

In addition to the cylinder for domestic use, the following items are required:

• a set of adapters for connecting to a furnace, burner or heating system;
• reducer for a propane cylinder;
• special gas hose with fittings;
• tools for insulating connections.

For maximum safety during installation, wrenches and other tools covered with brass or copper should be used. Such tools do not generate a spark when in contact with metal.

Features of filling a cylinder?

So, we figured out what types of gas cylinders are, found a suitable model and a complete set of necessary accessories. It's time to talk about how and where propane gas cylinders are refueled for domestic use.

Before filling a cylinder, it is imperative to make sure of the following:

• there is no damage on the body - rust, dents, violations of welding seams, cracked paint;
• the valve and the valve are visually in perfect order;
• there is no residual pressure in the empty container.

If everything is in order with the container, we start looking for a place where you can refuel the gas cylinder in compliance with all standards. In our country, there are specialized filling stations equipped with the necessary equipment and qualified employees. In turn, there are three refueling mechanisms at such stations:

• pumping - gas is pumped into the cylinder with special pumps;
• pump-evaporative - when pumping gas, special heating elements maintain a certain temperature, as a result of which the pressure in the system rises;
• pump-compressor - a compressor is used, which increases the pump performance, which in turn affects the rate of filling the tank.

At such filling stations, fire safety is maximally observed.

You can also fill the cylinder with propane at some gas stations. Before contacting the filling staff with a request to fill a household bottle, you should make sure that you have special equipment.

The specifics of refueling cars and household cylinders are slightly different. Unfortunately, gas stations often neglect this. Filling a household container at a gas station that is not properly equipped has a number of negative aspects:

• refuelers often ignore the expiration date and certification of household cylinders;
• there is no balance for weight control.

It is worth dwelling on the last point in more detail. As mentioned earlier, the household tank should be filled with propane taking into account the coefficient 1.43 - this is 85% of the volume of empty containers. Cars have special fuses that do not allow to fill in more gas than it should be. Ordinary household containers are not equipped with such sensors, therefore, when refueling, it is necessary to control their weight. Filling more than 85% poses a high risk of explosion, especially when exposed to temperatures.

If you have decided what kind of household cylinder you want to purchase, please contact our company. Here you can get additional advice, as well as refuel, order and buy everything you need to install gas equipment.

For manufacturing you will need:

- gas burner (bought in China)
- oxygen hose 1 meter
- nozzle for a large gas cylinder with a left-hand thread
- two clamps
- screwdriver
- scales
- large gas cylinder

Manufacturing process

The first step is to disassemble the gas burner. It is necessary to unscrew the nozzle. It is threaded and easy to remove. In the future, you can easily collect everything again and use it as intended.

Then we take the hose and put one end on the adapter for a large gas cylinder, and the other on the burner and tighten it well with clamps.

That's all, the adapter is ready. now it can be screwed onto the gas cylinder.

Important!
It's all the same gas! Be careful!
I fill it like this: first I let out the remaining air from the can, put it on the scales. The weight of an empty cartridge is 95 grams. Then I connect the can to the adapter and open the valves. A large cylinder must be placed on its side so that the liquid gas flows to the tap. I usually fill from 150 to 180 grams, no more, for this I keep the valve open for about 10 seconds. After refueling, I put it on the scales again and see the result.

Here's an adapter turned out, everything is pretty quick and simple!

If I missed anything, ask in the comments, I'll be happy to answer!
Thank you very much for your attention!

How to make your own gas refueling car at home

Today we will talk about how to independently refuel cars with natural gas at home from an ordinary stove. We will also consider the methods, technologies, instructions, drawings and descriptions of compressors and pumps for liquefying methane or propane in order to refuel a car with visual photos. We will learn how to make a mini gas car station yourself at home

Due to its low cost and environmental friendliness in use, natural gas has found wide application in the automotive industry. However, on the way from the main gas pipeline to the consumer's refueling cylinder, natural gas goes through several more intermediate stages.

There is no doubt that it is economically more profitable to operate a car on natural gas. And the more powerful and larger the engine, the faster the LPG pays off and the more significant the savings. At the filling station, gas is pumped into refueling bottle car. The operating pressure of the compressor is 1.6 MPa (16 atm). The gas pressure in the vehicle tank depends on the ambient temperature and varies within wide limits.

So, at an air temperature of 0 ° C, the pressure in the cylinder is 0.3 MPa (3 atm), and at a temperature of 20 ° C, its value increases to 1.2 MPa (12 atm). In addition to vehicles, gas filling stations are refueling cylinders for the use of liquefied gas by the population for domestic purposes and at small and medium-sized businesses.

In the previous materials, we cited calculations of reducing fuel costs, and came to the conclusion that, under any conditions, the cost of one kilometer of mileage is reduced on average by half. Now imagine that costs can be reduced not by two, but by 6-10 times. Do you think this is unrealistic? In fact, it is possible. How we will tell you further. You can refuel your vehicle at home using the gas supply. As you know, tariffs for household gas for the population are orders of magnitude lower than the price of gas at filling stations. And this is even through the counter.

If there is no meter and you pay at standard (albeit inflated) tariffs - then and so on. Everything is clear. Yes, it turns out that you will refuel the car for almost nothing. By the way, in the West or in America, such home gas stations are gaining more and more popularity, although there is not a big difference in the price of gas in the kitchen and at the gas station. It's another matter with us ... Calculating the cost per kilometer of run on gasoline and methane (according to the energy consumption of 1 cubic meter of methane \u003d 1 liter of gasoline), we took as a basis the cost of specialized filling complexes.

With savings, I think, everyone understands - even by the most conservative estimates, at least more than 10 times, provided that you honestly pay for everything using the domestic gas meter.

In addition to this, refueling the car with natural gas from the household network connected to your house or apartment will allow:

Again, the main thing is to reduce the cost of refueling the car. The cost of methane is several times lower than the cost of gasoline. The more intensively the car is used, the higher the economic effect.

Extend engine life. Methane gas, like propane-butane, does not wash off the oil film from the engine cylinder walls, which provides excellent lubrication of the piston group parts. In addition, methane, unlike gasoline, does not contain various additives that oxidize the oil itself, which has a positive effect on the resource and stability of the characteristics of the engine oil. Plus this, by about a quarter, prolongs the life of the spark plugs. Reducing the wear of engine parts increases the service life by 1.5-2 times, and the service life of the engine oil by 2-2.5 times.

The high octane number of natural gas (104-115) allows it to be used for any engines (ZAZ, LuAZ, VAZ, GAZ, Moskvich, UAZ, etc.), as well as in engines of most foreign cars. This also applies to trucks.

Significantly reduce emissions of harmful combustion products into the atmosphere. When gas is used as a fuel for a car, emissions of harmful toxic compounds of lead and aromatic compounds are completely absent, emissions of CO, CH, nitrogen oxides are reduced by several times, smoke from the exhaust pipe is reduced three times. Even if you are not an ardent fan of "green" vehicles, cars with installed methane gas equipment are exempted from environmental control when passing through a technical inspection.

A pre-built factory mobile gas filling station can be purchased. Unfortunately, the domestic industry does not produce such (it is understandable, no one will be given permission), and there are already quite a lot of foreign samples. For example, they are serially produced by Neuman ESSER (Germany), Maschinenfabrik (Austria), Litvin (France) and many others. The only but very significant disadvantage is the price. These gas stations are not cheap, especially for a person who wants to save on this. In reality, everything turned out to be banal simple. Anyone can buy a special high-pressure pump, which is connected to a low-pressure domestic gas pipeline and fills a car equipped with LPG (methane gas).

At the same time, no special permits or safety requirements from the owner are required. Let me emphasize - special! And then - just a fairy tale. You connect a special high-pressure hose to the car's charging connection, and ... you will have to wait a little longer than at a proprietary filling station.

How many? It all depends on the performance of the pump you choose. For example, the weakest one with a capacity of 3 cubic meters / hour can take 5-6 hours to fill one cylinder, while an average capacity of 10 cubic meters / hour will take only one and a half hours. How long will you say? And you calculate how long your car is idle near the house. During this time, he may well refuel. You sleep, the car is refueling. When the limit pressure is reached, the system will automatically shut down. In the morning a car with cylinders filled to capacity is waiting for you. Everything is great, especially since the bills that were not spent on fuel continue to lie in your pocket, and not in the cash register of the gas station.

Household gas compressors for filling a car, gas cylinders at home with natural gas from a low pressure network

All is well and beautiful, but we will still put a fly in the ointment into this beautiful barrel of honey. With all the visible advantages of using a home gas station, there are no less minuses.

Firstly, the cost of installing HBO.

Secondly, the cost of a gas compressor.

Thirdly, the weight and dimensions of the high pressure cylinders.

Fourthly, the network of methane gas stations is not sufficiently extensive (you have to travel not only near your home).

But, there is a category of citizens for whom these disadvantages are not critical. They use vehicle not only to move their mortal body from home to work and back, they earn on it. For those who have cars with a huge annual mileage, switching to methane and installing a gas filling station is a very relevant solution.

You can make such a compressor yourself. Option, again ten times cheaper, but requires desire, time and, most importantly, "straight" arms, moreover, they must grow from the right place.

Below is an article for those who are interested in the second method. The implementation of the first, especially, does not need clarification.
Guide self-production set of gas equipment for refueling a car household gas

At the beginning, it is necessary to clarify: there is a gas apparatus for compressed gas and an apparatus for liquefied gas. Compressed gas equipment uses conventional natural gas - methane, which can be taken from residential or industrial gas networks. The only problem is how to fill this gas into the car at home.

In a conventional gas pipeline supplied to a home stove, column or boiler, the pressure of natural gas is about 0.05 atm., And in a high-pressure gas cylinder up to 200 atm. Therefore, a compressor is needed that will raise the gas pressure to the required value. The design of such a compressor is somewhat different from that used in conventional household appliances.

A conventional single-circuit compressor is capable of raising the pressure to a maximum of 20 -25 Atm., And to refuel a gas cylinder, you need to reach 200 Atm. This is achieved by adding additional circuits to the system. It looks like a set of several compressors, each subsequent one, of which compresses the gas previously compressed by the previous one to a higher pressure.
In general, a high pressure compressor circuit looks like this.

The principle of operation of the compressor for refueling auto gas:

Gas from the household gas pipeline through the inlet filter (1) is fed through the inlet valve (2) to the primary cylinder. Compression occurs and through the outlet valve (3) through the pipeline through the cooling radiator (4) to the cylinder of the next circuit. Further, the gas previously compressed in the primary circuit is compressed to an even higher pressure. All processes are repeated in the third circuit. The number of contours can be increased to five. There are three of them in the above diagram. But this does not change the principle.

Natural gas compressed to the required pressure (this is about 200 atm.) Passes through the pressure switch (11), is cleaned in a molecular filter and through a safety valve is fed into the cylinder of the refueled car or into a reserve high-pressure cylinder. The filling time will completely depend on the productivity of the installation.

In order to speed up the refueling time of the vehicle, additional stationary cylinders can be used. Then, in free time, the compressor pumps gas into these stationary cylinders. And when you need to quickly refuel your car, you distill the methane directly from them. Thus, the refueling time can be reduced to 10-15 minutes.
Description of a home-made device for refueling a car with household gas.

As previously stated, this requires a high pressure compressor (up to 200 kg / cm2). Compressors such as GP4, NG-2, AKG-2 can be used, but they require a powerful electric motor, which is not suitable for many. A good option - this is the use of the AK 150S air compressor. It is used on modern armored vehicles and in aviation. This compressor is quite small-sized, lightweight, requires a low-power electric motor of 1.5-3 kW, which allows it to be connected to an apartment or garage electrical network. The main question is where to get it. But believe me, this is not as difficult a task as it seems at first glance. Often they can be written off, while spending no more than 10% of their resource. Whoever is looking will always find (sometimes for very little money or liquid barter

From a household gas network through a rubber hose (it is possible from a gas welding machine), gas is supplied through a valve to a gas filter (7). The pressure gauge (2), connected through the adapter (3), serves to control the pressure in the gas network, The gas in the filter (7) is cleaned of impurities and supplied to the compressor (10), where it rises to 150 kg / cm2. Then the gas goes to a water separator (18), a high pressure gas filter (19), a pressure machine (20) of the ADU-2S type. The gas is then fed to the filling valve.

When the pressure rises above 150 kg / cm2, the ADU 2 valve opens and the gas returns through the tube (23) to the compressor inlet. The NMP 100 type pressure gauge is used with a measurement range of 0-400 mm of water. Art.
The function of the gas filter can be performed by a new fine fuel filter for diesel engines. A tap (17) is used to drain condensate from the moisture separator. A pressure gauge (22) (0-250) kg / cm2 is installed to control the pressure at the compressor outlet.

It is fastened to the compressor flange (1) by means of sheet metal, studs in flocks (8) through the gasket (10), the housing (11). A plate (12) is welded to the bottom of the casing for fastening the compressor with a lubrication unit (Fig, 5). Bearing (4) of type 205 is pressed into the housing (11) (Fig. 3). A sleeve (7) is pressed into the bearing from the slot, which is fastened with a retaining ring (19). The spline shaft (6) of the compressor enters the bushing on one side, and on the other side the shaft (17) is pressed in, the key of which enters the splines of the bushing (7). This is done in order not to cut splines on the shaft (17). After pressing, the shaft (17) is neatly tacked to the bushing (7) by welding.

After that, the body (11) is closed with a cover (14) with an oil seal (13). The cover is fastened with bolts (5). On the other end of the shaft (17) a drive pulley (15) with a key (16) is fitted. The compressor lubrication unit is shown in fig. 2 and fig. 5. The base is a tank (24) (Fig. 2), which can be made from a rectangular profile or welded from sheet metal. A drive unit with a compressor is attached to the tank from above. Hole (13) (Fig. 3) must line up with hole (11) (Fig. 5) on the tank. Top of the tank in convenient location a hole is cut out to which the filler neck (3) and cover (2) are welded (fig. 5).

Hole (4) (fig. 5) serves to supply oil to the pump. Shafts (6) and (17) are connected by means of plate (7) and bushing (8). The bearing (12) is fastened by a housing (15) with a cover (16), an oil seal (13). The cover is attached to the body with screws (14). A pulley (18) with a key is put on the shaft (17). The oil pump is used from the GAZ-51, 52, 69 car, but it should be borne in mind that the pumps differ in the length of the drive shaft.

The oil level is monitored by a sight glass (11) of arbitrary design. The lubrication system works like this. The torque from the electric motor pulley through the belt drive is transmitted to the pulley (16) (Fig. 2), (18) (Fig. 5) and through the shaft (17), bushing (8) and plate (7) is transmitted to the shaft (6) pump drive (1). The oil enters through the hole (4) into the pump (1) (Fig. 5), (8) (Fig. 2), passes through the adapter (3), into which the automobile pressure sensor (4) is screwed in, and is fed through the tube to the inlet fitting (12) oil supply to the compressor. The fitting (12) in Fig. 2 is conditionally deployed. It is screwed into hole (3) (fig. 3). The thread diameter depends on the tube you have, which can be used from hydraulic system autotractor units.

Then the oil passes through the compressor lubrication channels (fig. 3, fig. 4), collects in the lower part and is discharged through the oil drain hole fig. 4, fig. 11 (part 11) then flows through the hole (13) (Fig. 3) into the reservoir (24) (Fig. 2) Part of the oil passes through the bearing (4) (Fig. 3) and lubricates it. Part (7) ( fig. 11) can be made from the compressor drive gear, which must be purchased. To do this, it is necessary to grind off the gear ring to the dimensions shown in Fig. 11 (detail 7) .A car bulb can be connected to the pressure sensor (4) (fig. 2).

Instead of a sensor, a pressure gauge can be connected for monitoring. In order to divert the gas that has broken through the piston rings into the housing of the drive unit, there is a threaded hole near the upper part of the housing (Fig. 11), (det. 11), section A-A, into which the fitting (13) ( fig. 2). A rubber tube is put on the fitting and is displayed above the roof of the garage, at home. Although the design of the filling device provides for the localization of possible gas emissions into the room, it is advisable to install it outside the room.

On average, filling the cylinders with gas lasts 1-1.5 hours. To reduce the filling time, two compressors can be paired. Truck owners can use 4 compressors. In fig. 10 shows a schematic electrical diagram for connecting a 3-phase electric motor to a single-phase network.

The voltage is supplied to the IM motor through the Q1 circuit breaker, the magnetic starter MP. When the "start" button is pressed, relay P1 is activated, which, with its contacts P1.2, supplies voltage to the coil of the MP starter and connects the starting capacitors Cn with contacts P1.1. In this case, the starter is triggered and connects the motor and the working capacitors Cp to the network. At the same time, the auxiliary contacts of the MP 1.1 starter close and the starter becomes self-locking.

When the "Start" button is released, the Cn turns off. When the "Stop" button is pressed or when the thermal protection relay of the PT motor is triggered, the circuit is opened, the starter is disconnected, the motor is turned off and the circuit returns to its original position. When connecting motor windings with a delta Cp \u003d 4800 (IHOM / U), where IHOM is the rated motor current, U is the voltage in the network. Cn \u003d (2-3) Cf.

When storing the car in the garage, a tube is put on the fitting, which is led out above the roof of the garage. With this design, you will be fully guaranteed against any gas leaks. Before using cylinders, it is necessary to check their working pressure, volume, technical condition. Outer surface must be free from dents, cracks, deep scratches and traces of corrosion. Near the VD neck it is indicated:
- date of test and date of next test;
- type of heat treatment (N - normalization, W - hardening with tempering);
- operating pressure;
- test hydraulic pressure (p225);
- actual weight, brand of the plant,

To connect gas pipelines, special adapters are used (Fig. 8), which are screwed into the cylinder instead of the valve, lubricating the threads with lead red lead. The tightening torque of the adapter is 45-50 kg / m (450-500) Nm. This can be checked with a special torque wrench, which can be borrowed from a car service station. When the valve or adapter is fully screwed in, 2-5 threads should remain on its threaded part. The tapered thread size (fig. 8) depends on the types of cylinders.

High-pressure pipes have a non-gasket nipple connection, which, when the union nut is tightened, abuts against the tapered surface of the fitting and, deforming, seals the connection point. If you have purchased old pipes, you need to cut off the end of the pipe with the nipple and put on a new nipple, coat it with red lead and tighten the union nut. After carefully tightening all threaded connections, the filling valve is opened, the filling device is connected and air is pumped in to half of the working pressure, the connections are checked, and in the absence of gaps, pumped to full working pressure.

Air leaks must be eliminated after the pressure has been completely relieved. If there are no gaps, then open the filling valve and completely release the air from the system and pump gas into the cylinder. After that, the flow valve is opened and gas is introduced to the HP reducer, its operation is checked.
To do this, using the fitting (13) (Fig. 1) set the gas pressure at the outlet to 10 kg / cm2, then purge the low pressure system with gas until air is completely removed, start the engine on gas and check the pressure at the outlet of the HP reducer. may fall slightly. All work must be carried out outside the premises. After that, the actuation of the reducer safety valve is checked. To do this, screw the fitting (13) smoothly (Fig, 1) and gradually increase the pressure at the reducer outlet until the valve is triggered. It should work at a pressure of 15-17 kg / cm2.

If the valve trips at a different pressure, loosen the locknut on the valve and adjust the tripping. After that, check the tightness of the main valve. To do this, completely unscrew the fitting (13), while the gas should not enter the low pressure line. If the pressure slowly increases, then the valve seat in the reducer is changed or taken to the workshop. If everything is in order, make a test drive and check the low pressure reducer.
How to do this is well described in the operating instructions for gas equipment on liquefied gas and there is no need to describe it.It should be borne in mind that when using a low pressure reducer from a nozzle for liquefied gas, your car may slightly lose dynamism. To prevent this from happening, you can drill the jets in the gearbox by 1-2 tens, but then the mileage and efficiency will decrease. So the decision is yours.

You need to know that natural gas is lighter than air and rises upwards, unlike liquefied gas, which spreads along the ground, fills all the cracks and basements. Therefore, during operation, this feature must be taken into account.

Before each departure and return to the garage, after maintenance and repair it is necessary to check the tightness of the gas system. The most readily available methods for detecting gas leaks are odor control and soaping. If you smell gas while driving, you must eliminate the malfunction. If you cannot eliminate the malfunction, it is necessary to release the gas from the cylinders into the atmosphere (in the absence of people nearby, open fire, other vehicles).

When the gearbox freezes and the engine starts in winter period to warm up, you must use hot water, it is strictly forbidden to use open fire! When gas equipment ignites, it is necessary to close the valves, turn off the filling system. To extinguish a fire, you must have a carbon dioxide fire extinguisher on hand. In this case, it is necessary to water the cylinders with water in order to prevent an increase in pressure in them.

Once every three years, it is necessary to check the high-pressure cylinders by a hydraulic test, once a year - it is necessary to take it for inspection. It is strictly forbidden to attach structural elements to the surface of the cylinders by welding. When refueling a car, it is necessary to control the gas pressure at the compressor inlet and outlet, the temperature of the cylinders, and the pressure in the lubrication system. There must be no people in the vehicle while refueling.

If gas leaks are detected, refueling must be carried out under the following conditions: refuel only with the flow valve closed, when refueling do not stand near the refueling hose, do not tighten the nuts during refueling under pressure, do not knock metal objects on the refueling system parts. Disconnect the filling hose only after closing the filling valve. When the working pressure in the cylinders is reached, turn off the compressor engine, close the filling valve, and close the valve at the compressor inlet.

In conclusion, I would like to say that the task was to give you a simplified, affordable and at the same time safe and efficient design of the filling device, which can be assembled in a fairly short time and get moral and material pleasure from your work.

And finally, let's make ecologists and Greenpeace society happy. A methane engine has much less exhaust gas toxicity. The amount of toxic carbon monoxide CO (carbon monoxide) decreases more than threefold, and the content of carcinogenic CH hydrocarbons, consisting of particles of unburned fuel, decreases 1.6 times. The concentration of nitrogen oxide NO and NO2 dioxide when the engine is running on gas is reduced by 1.2 times.

What conclusions can be drawn from this? The conversion of modern cars to methane, although costly, is an easy operation. At the same time, due to the lower cost of gas, the costs are quickly paid off. If we take into account the possibility of installing a gas station at home, then this is the most cost-effective option on the market.

Unfortunately, accidents at gas stations, despite the high safety of modern gas equipment, do occur. And sometimes the fault is not even the negligent attitude of the car owner to the refueling process, or the violation of the safety rules of the gas station employee. The reason for an emergency at gas filling stations most often becomes banal awareness, people simply do not know how to behave correctly at gas filling stations. No, I do not want to say that accidents do not happen at ordinary gas stations, just gas fuel is different from classic gasoline and diesel fuel. We are talking about a completely different refueling technology and a completely different state of these types of fuel, not to mention the flammability ...

In this article I want to talk about the safety rules at the gas station, as well as about how to properly fill a car with gas independently, if necessary.

To begin with, about what can not be done at the gas station

At gas filling stations, it is prohibited:

1. Well, first of all, of course, smoke or use open sources of fire. I think there is no need to explain here, we all know what gas is and what happens if a large amount of gas is abruptly set on fire. An explosion of unprecedented proportions is taking place, so in no case, under any circumstances, do not break this rule "No. 1".
2. Refuel the vehicle with the engine running. When the engine is running, the fuel line is functioning, so there is a high probability of a sharp increase in pressure in the fuel line, which is fraught with damage to valves and many other equally important components of gas equipment.
3. Refuel the faulty LPG. Before refueling your car with gas, make sure that the valves, VZU, are in order. is not damaged, and the gas equipment itself is in good order and has no leaks.
4. Start refueling without the permission of the operator of the gas station.
5. Refuel with an incorrectly installed "nozzle".

How to properly fill a gas cylinder on a car with LPG?

First of all, you must remember one thing - refuel your car if there is an operator or a refueller at the gas station - prohibited! For such a violation, the employee can be punished or even fired, and you, at the very least, will receive a warning or perhaps even a fine! All you need to do is inform the employee of the location of the remote filling device.

There are really exceptions when there is no refueling agent or the refueling itself provides for the possibility of self refueling, in which case the following tips will help you correctly refuel with gas at the filling station.

Of personal experience... For example, I once witnessed a simply egregious case of violation of safety rules by an employee of a gas station. The operator of the gas station, in a state of strong alcoholic intoxication, tried to connect the pistol and could not but connect it to the VZU, he could hardly stand on his feet. The worst thing was that a few minutes after his unsuccessful attempts, the tanker decided "out of grief" to light a cigarette, while holding the pistol in his hands. I'll tell you honestly, I've never seen people get into cars so quickly and disperse in all directions ... 🙂 Laughter, laughter, but everything could end in tears ...

1. The first thing to do is drive up to the column and turn off the engine.

2. Carry out a visual check for serviceability, although this is best done before going to refuel.

3. Connect the adapter, if it is provided for by the design of your LPG and install the pistol in the air intake.

4. Switch on the gas supply and control the filling of the gas cylinder. Here it must be remembered that only the amount of gas that is physically placed in it can fit into the cylinder, you should not shake the car, stagger in order to pump more gas into your cylinder. I wrote about this in more detail in my previous article:.

5. After the cylinder is filled, the automatic gas station will cut off the gas supply. You will notice this by the fact that the numbers in the "liters" and "rubles" fields will stop. However, if you do not need a full bottle, you can stop filling at any time.

6. All that is left for you is to disconnect the "gun" and remove the adapter, if you installed one.

After finishing refueling, do not forget to pay the bill. That's actually the whole procedure, as you can see nothing complicated, the most important thing is to try to do it yourself several times.

Finally, a video about how to properly refuel a car on your own:

Thank you all for your attention, I hope the article was useful to you !?

Despite the significant increase in energy prices, gas is still the most common type of fuel. It is used for various purposes, including refueling cars. The installation of LPG equipment on vehicles allows you to reduce the cost of purchasing fuel.

You can purchase suitable cylinders and other equipment on the website http://safegas.com.ua/ru/gazovye-ballony/.

Necessary equipment

Gas supplied to residential buildings is much cheaper than liquefied gas at specialized gas stations. Therefore, filling cylinders from a stove is much more profitable. But in order to independently carry out this process, you will need special equipment.

Today there are two options available:

• mobile gas filling stations for industrial production. Such equipment is not produced in our country. Therefore, you will have to turn to foreign manufacturers. Plants for filling gas cylinders are produced in France, Austria, Germany and many other countries;
• homemade installations. In order to manufacture such equipment, you must have certain skills. It is important to understand that accidents can occur if the domestic gas leaks.

A feature of the equipment, which allows filling cylinders with household gas, is the use of several compressors combined in different circuits. This allows for a gradual increase in gas pressure.

The principle of operation of a gas filling installation

Since the gas pressure in the gas pipeline is about 0.05 atm., Then before refueling it must be compressed to 200 atm. This problem is solved by the installation for filling cylinders. It can include from 3 to 5 circuits, while the principle of operation will be unchanged:

1. The gas passes the filter installed at the inlet to the system and enters the cylinder of the circuit.
2. The compressor builds up pressure and the compressed gas is fed to the cooling radiator.
3. The gas is fed through the pipeline to the next circuit, where it is compressed even more.

All processes are repeated in each circuit. Before filling into a high pressure cylinder, the gas is passed through a molecular filter.

The refueling process lasts from 1.5 to 2 hours. If you use reserve cylinders, into which gas will be injected in advance, then the time can be reduced to 10-15 minutes.

When using home-made gas filling equipment, you must be extremely careful. Gas leaks can cause various accidents.
