Industrial gearboxes for flame treatment type BPO-5 - capacity 5 m3/hour, outlet pressure 1 - 3 kgf/cm2.
Basic information about gas welding torches
Torches type G2 "Malyutka", "Asterisk" are the most common and versatile welding torches, and when buying a torch for general purposes, it is worth buying them. Burners can be equipped with different tips, and depending on the installed tip, have different characteristics:
Tip No. 1 - thickness of the welded metal 0.5 - 1.5 mm - average consumption of acetylene / oxygen 75/90 l / h
Tip No. 2 - thickness of the welded metal 1 - 3 mm - average consumption of acetylene / oxygen 150/180 l / h
Tip No. 3 - thickness of the welded metal 2 - 4 mm - average consumption of acetylene / oxygen 260/300 l / h
It is important to know and remember that acetylene torches cannot work stably on propane, and for welding, soldering, heating parts with a propane-oxygen flame, it is necessary to use GZU type burners and others specially designed to work on propane-butane. It must be borne in mind that welding with a propane-oxygen flame gives worse weld characteristics than welding with acetylene or electric welding, and therefore it should be resorted to only in exceptional cases, but soldering or heating with propane can be even more comfortable than with acetylene. The characteristics of propane-oxygen burners, depending on the installed tip, are as follows:
Tip No. 1 - average consumption of propane-butane / oxygen 50/175 l / h
Tip No. 2 - average consumption of propane-butane / oxygen 100/350 l / h
Tip No. 3 - average consumption of propane-butane / oxygen 200/700 l / h
For the correct and safe operation of the burner, it is very important to install correct pressure gas at its inlet. All modern burners are injector, i.e. combustible gas is sucked into them by an oxygen jet passing through the central channel of the injector, and therefore the oxygen pressure must be higher than the pressure of the combustible gas. Usually set the following pressure:
Oxygen pressure at the burner inlet - 3 kgf/cm2
The pressure of acetylene or propane at the inlet to the burner is 1 kgf / cm2
Injection burners are the most resistant to backfire and are recommended for use. In old, non-injector burners, the pressure of oxygen and combustible gas is set equal, due to which the development kickback flame is lightened, this makes such a torch more dangerous, especially for beginner gas welders who often manage to dip the torch mouthpiece into the weld pool, which is extremely dangerous.
Also, you should always follow correct sequence opening / closing the burner valves when it is ignited / extinguished. When ignited, oxygen is always opened first, then combustible gas. When extinguishing, the combustible gas is closed first, and then oxygen. Please note that when the burner is extinguished in this sequence, popping may occur - do not be afraid, this is normal.
Be sure to correctly set the ratio of gases in the flame of the burner. With the correct ratio of combustible gas and oxygen, the core of the flame (a small bright luminous area right at the mouthpiece) is fat, thick, clearly defined, does not have a veil in the flame of the torch around. With an excess of combustible gas, there will be a veil around the core. With an excess of oxygen, the nucleus will become pale, sharp, prickly. To correctly set the composition of the flame, first give an excess of combustible gas so that a veil appears around the core, and then gradually add oxygen or remove combustible gas until the veil completely disappears, and immediately stop turning the valves, this will be the optimal welding flame. Welding should be carried out with a flame zone at the very tip of the core, but in no case should the core itself be stuck into the weld pool, and not carried too far.
Do not confuse a welding torch and a gas cutter. Welding torches have two valves, and a cutting torch has three valves. Two gas cutter valves are responsible for the preheating flame, and the third additional valve opens a jet of cutting oxygen, which, passing through the central channel of the mouthpiece, causes the metal to burn in the cut zone. It is important to understand that a gas cutter cuts not by melting metal from the cut zone, but by burning it out, followed by removal of slag by the dynamic action of a jet of cutting oxygen. In order to cut metal with a gas cutter, it is necessary to light a preheating flame, acting in the same way as in the case of ignition of a welding torch, bring the cutter to the edge of the cut, heat a small local area of metal to a red glow and abruptly open the cutting oxygen valve. After the metal catches fire and a cut begins to form, the cutter begins to move in accordance with the required cut path. At the end of the cut, the cutting oxygen valve must be closed, leaving only the preheating flame. The cut should always start only from the edge, but if there is an urgent need to start the cut not from the edge, but from the middle, then you should not “pierce” the metal with a cutter, it is better to drill through hole and start cutting from it, it's much safer. Some acrobatic welders manage to cut thin metal with conventional welding torches by deftly manipulating the fuel gas valve, periodically shutting it off and leaving pure oxygen, and then re-igniting the torch on hot metal, and although this can be seen quite often, it is worth warning that you do this dangerous, and the cut quality is poor.
How many cylinders can be transported without special permits
The rules for the transportation of gases by road are regulated by the Transportation Rules dangerous goods road transport (POGAT), which in turn are consistent with the requirements of the European Agreement concerning the International Carriage of Dangerous Goods (ADR).
Paragraph 1.2 states that "The Rules do not apply to ... the carriage of a limited number of dangerous substances in one vehicle, the carriage of which can be considered as the carriage of non-dangerous goods. The limited number of dangerous goods is determined in the requirements for the safe carriage of a particular type of dangerous goods. When determining it, it is possible to use the requirements of the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR)."
According to ADR, all gases belong to the second class of hazardous substances, while different gases may have different hazardous properties: A - asphyxiating gases, O - oxidizing substances, F - flammable substances. Asphyxiating and oxidizing gases belong to the third transport category, and flammable - to the second. The maximum amount of dangerous goods, the carriage of which is not subject to the Rules, is indicated in ADR clause 1.1.3.6, and is 1000 units for the third transport category (classes 2A and 2O), and for the second transport category (class 2F) the maximum amount is 333 units . For gases, one unit is understood as 1 liter of vessel capacity, or 1 kg of liquefied or dissolved gas.
Thus, according to POGAT and ADR, the following number of cylinders can be freely transported by car: oxygen, argon, nitrogen, helium and welding mixtures - 24 cylinders of 40 liters each; carbon dioxide - 41 cylinders of 40 liters; propane - 15 cylinders of 50 liters, acetylene - 18 cylinders of 40 liters. (Note: acetylene is stored in cylinders dissolved in acetone, and each cylinder, in addition to gas, contains 12.5 kg of the same combustible acetone, which is taken into account in the calculations.)
When transported together various gases ADR 1.1.3.6.4 should be followed: "If dangerous goods belonging to different transport categories are transported in the same transport unit, the sum of the quantities of substances and articles of transport category 2 multiplied by "3" and the quantities of substances and articles transport category 3 should not exceed 1000 units".
Also in ADR, paragraph 1.1.3.1 contains an indication that: "The provisions of ADR do not apply ... to the transport of dangerous goods by private persons when these goods are packed for retail and are intended for their personal consumption, use in the home, leisure or sports, provided that measures are taken to prevent any leakage of the contents into normal conditions transportation".
Additionally, there is an explanation of the DOBDD of the Ministry of Internal Affairs of Russia dated July 26, 2006, ref. 13/2-121, according to which "Transportation of compressed argon, dissolved acetylene, compressed oxygen and propane in cylinders of 50 liters each without complying with the requirements of the Rules for the transport of dangerous goods by road, it is possible to carry out on one transport unit in the following quantities : dissolved acetylene or propane - no more than 6 cylinders, argon or compressed oxygen - no more than 20 cylinders. In the case of the joint transportation of two of the indicated dangerous goods, the following ratios by the number of cylinders are possible: 1 cylinder with acetylene and 17 cylinders with oxygen or argon; 2 and 14, 3 and 11, 4 and 8, 5 and 5, 6 and 2. The same ratios are possible in the case of carriage of propane and compressed oxygen or argon. their ratio, and for the joint transportation of acetylene and propane - 6 cylinders, also regardless of their ratio.
Based on the foregoing, it is recommended to be guided by the instructions of the DOBDD of the Ministry of Internal Affairs of Russia dated July 26, 2006, ref. 13 / 2-121, the least is allowed there and the amount is directly indicated, what is possible and how. In this instruction, of course, they forgot about carbon dioxide, but you can always say that it is equal to argon, traffic police officers, as a rule, are not great chemists and this is enough for them. Remember that POGAT / ADR is completely on your side here, carbon dioxide can be transported through them even more than argon. The truth will be yours anyway. As of 2014, the author is aware of at least 4 lawsuits won against the traffic police, when people were tried to be punished for transporting fewer cylinders than fall under the POGAT / ADR.
Examples of using the above data in practice and in calculations
Question: How long will gas and wire last when welding with a semiautomatic device with a 0.8 mm wire cassette weighing 5 kg and a 10 liter carbon dioxide cylinder?
Answer: Welding wire SV-08 with a diameter of 0.8 mm weighs 3.950 kg 1 kilometer, which means that there are approximately 1200 meters of wire on a 5 kg cassette. If the average feed rate for such a wire is 4 meters per minute, then the cassette will go in 300 minutes. Carbon dioxide in a "large" 40-liter cylinder is 12 cubic meters or 12,000 liters, if converted to a "small" 10-liter cylinder, then there will be 3 cubic meters of carbon dioxide in it. meters or 3000 liters. If the gas flow rate for purge is 10 liters per minute, then a 10-liter cylinder should last 300 minutes or for 1 0.8 wire cassette weighing 5 kg, or a "large" 40-liter cylinder for 4 5 kg cassettes.
Question: I want to put a gas boiler in the country and be heated from cylinders, how long will one cylinder last?
Answer: In a 50-liter "large" propane cylinder, there are 21 kg of liquefied gas or 10 cubic meters of gas in gaseous form, but it is impossible to convert it directly into cubic meters and calculate the consumption from them, because the calorific value of liquefied propane-butane is 3 times higher than the calorific value of natural gas, and the consumption of natural gas is usually written on boilers! It’s more correct to do this: we find the boiler data immediately for liquefied gas, for example, take the very common AOGV-11.6 boiler with a capacity of 11.6 kW and designed for heating 110 square meters. meters. On the ZhMZ website, the consumption is immediately indicated in kilograms per hour for liquefied gas - 0.86 kg per hour when working on full power. Divide 21 kg of gas in a cylinder by 0.86 kg / hour = 18 hours of continuous burning of such a boiler on 1 cylinder, this will actually happen if it is -30C outside at standard house and the usual requirement for the air temperature in it, and if it is only -20C outside, then 1 cylinder will be enough for 24 hours (day). We can conclude that in order to heat an ordinary house of 110 square meters. meters of bottled gas in the cold months of the year, you need about 30 bottles per month. It must be remembered that due to the different calorific value liquefied and natural gas, the consumption of liquefied and natural gas at the same power for boilers is different. To switch from one type of gas to another in boilers, it is usually necessary to change jets / nozzles. And now, for those who are interested, you can also calculate through cubes. On the same website of ZhMZ, the consumption of the AOGV-11.6 boiler for natural gas is also given, it is 1.3 cubic meters per hour, i.e. 1.3 cubic meters of natural gas per hour are equal to the consumption of liquefied gas 0.86 kg / hour. In gaseous form, 0.86 kg of liquefied propane-butane is approximately equal to 0.43 cubic meters of gaseous propane-butane. Remember that propane-butane is three times "more powerful" than natural gas. We check: 0.43 x 3 \u003d 1.26 cubes. Bingo!
Question: I bought a burner of the GV-1 type (GVN-1, GVM-1), connected it to the cylinder through the RDSG-1 "Frog", but it barely burns. Why?
Answer: For the operation of gas-air propane burners used for gas-flame treatment, a gas pressure of 1 - 3 kgf / cm2 is required, and a household gearbox designed for gas stoves, gives out 0.02 - 0.036 kg / cm2, which is clearly not enough. Also, household propane reducers are not designed for large capacity to work with powerful industrial burners. In your case, you need to use a gearbox type BPO-5.
Question: Bought gas heater to the garage, found a propane reducer from a BPO-5 type gas cutter, connected the heater through it. The heater blazes with fire and burns unsteadily. What to do?
Answer: Household gas appliances are usually designed for a gas pressure of 0.02 - 0.036 kg / cm2, which is exactly what a household reducer of the RDSG-1 "Frog" type produces, and industrial cylinder reducers are designed for a pressure of 1 - 3 kgf / cm2, which is at least 50 times more . Naturally, when blown in a household gas appliance such overpressure, it can't work properly. You need to study the instructions for your gas appliance and use the correct reducer that produces exactly the gas pressure at the inlet to the appliance that it requires.
Question: How much acetylene and oxygen is enough when welding pipes for plumbing work?
Answer: A 40 liter bottle contains 6 cu. m of oxygen or 4.5 cubic meters. m of acetylene. The average gas consumption of a G2 type burner with a No. 3 nozzle installed, most often used for plumbing work, is 260 liters of acetylene and 300 liters of oxygen per hour. So oxygen is enough for: 6 cubic meters. m = 6000 liters / 300 l / h = 20 hours, and acetylene: 4500 liters / 260 l / h = 17 hours. Total: a pair of fully charged 40-liter acetylene + oxygen cylinders is approximately enough for 17 hours of continuous burning of the burner, which in practice is usually 3 shifts of the welder's work for 8 hours each.
Question: Is it necessary or not, according to POGAT / ADR, to draw up special permits to transport 2 propane tanks and 4 oxygen tanks together in one vehicle?
Answer: According to ADR clause 1.1.3.6.4, we calculate: 21 (weight of liquid propane in each cylinder) * 2 (number of propane cylinders) * 3 (coefficient from ADR clause 1.1.3.6.4) + 40 (volume of oxygen in the cylinder in liters, compressed oxygen in the cylinder) * 4 (number of oxygen cylinders) = 286 units. The result is less than 1000 units, such a number of cylinders and in such a combination can be transported freely, without issuing special documents. In addition, there is an explanation of the DOBDD of the Ministry of Internal Affairs of Russia dated July 26, 2006, ref. 13/2-121, expressly indicating that such transportation is allowed to be carried out without complying with the requirements of the POGAT.
When gas comes to a rural settlement, civilization comes to it. Stove heating, or individual water heating with a boiler on solid fuel, is not only the romantic crackle of firewood in the firebox. Heating solid fuel- it's always soot, smoke and soot, the need for annual repainting of ceilings. And besides the troubles associated with constant dirt, it is also necessary to procure or purchase and store somewhere a supply of firewood for the whole winter.
Unfortunately, natural pipeline gas is not installed everywhere. In many settlements, residents have to be content with gas in cylinders. And people are interested in how many liters of gas are in a 50-liter bottle?
What is city gas
Recall the basics of school organic chemistry. The first is methane. The molecule of this gas consists of one carbon atom surrounded by four hydrogen atoms.
If you slightly lengthen the chain - instead of one of the hydrogen atoms, “attach” one carbon, attach hydrogen atoms to the remaining three of its bonds, you get the next member of the family of saturated hydrocarbons, ethane.
Starting from the beginning of the chain, we have:
- methane CH 4 ;
- ethane C 2 H 6 ;
- propane C 3 H 8;
- butane C 4 H 10.
The last two compounds - propane and butane - are the content
Physical properties of these chemicals
Propane at normal atmospheric pressure is a liquid in the temperature range from -187.7 to -42.1 °C. Below the specified interval, propane crystallizes, and above, respectively, it passes into a gaseous state. Butane has this range: -138.3 ... -0.5 ° С. As you can see, the liquid transition temperatures for both gases are not much below zero, which makes them quite easy to liquefy by increasing the pressure.
Gas storage methods
In everyday life, as a rule, a propane-butane mixture is used. In private homes, standard 50-liter gas cylinders are used to store a liquefied mixture. They act a little differently when supplying gas to high-rise buildings. Well, how many liters of gas can fit in a 50-liter bottle?
And to change cylinders with 42 liters of gas (that's how much is stored in the cylinder) plus the weight of the cylinder itself on all floors and apartments ... Therefore, in such cases, in the courtyard of the house, as a rule, a grounded storage is arranged, into which the gas mixture is delivered by special gas carriers. In a special device, it is transferred to the gaseous phase and in this form enters the household pipeline.
Gas cylinder volume
So how many cubic meters of gas are in a 50-liter bottle? To answer this question, it is necessary to decide which gas we are interested in. 42 liters of liquid mixture of gases are poured into the cylinder. But how much is it in kilograms, cubic meters? The density of liquefied: propane - 0.528 kg / l, butane - 601 kg / l.
In order to find out how many liters of gas are in a 50-liter cylinder, we will make small calculations.
Propane |
||
Liquid phase density | ||
Liters in a bottle | ||
The mass of gas in the cylinder | ||
Density of the gaseous phase | ||
Butane |
||
Liquid phase density | ||
Liters in a bottle | ||
The mass of gas in the cylinder | ||
Density of the gaseous phase | ||
Volume occupied by 42 liters of gas (1 cylinder) | ||
Thus, how many liters of gas are in a 50-liter cylinder depends on what composition is pumped into it. If we assume that the cylinder is filled with one propane - 22.44 m 3, butane - 16.67 m 3. But since a mixture of these chemical compounds is used in everyday life, the indicator will be somewhere in the middle.
If we assume that propane and butane are in the cylinder in equal proportions, then the answer to the question of how much gas is in a 50-liter cylinder (m3) is about 20.
Safety precautions when handling gas cylinders
- Never remove plates and labels from cylinders.
- Do not lift or move the cylinder by holding on to the valve.
- Leaks should be checked with soapy water, not with a lit match.
- Open the cylinder valve smoothly.
- Never heat the balloon.
- Independent pumping (overflow) of liquefied gas into other containers is prohibited.
Here are collected the most frequently asked questions about the installation and operation of gas equipment. Some issues are fully disclosed, others are considered in separate articles and links are provided to them. Go…
What gas is used in HBO?
LPG uses liquefied natural gas (aka propane, aka propane-butane, aka LPG) or compressed natural gas (aka CNG, aka methane, aka CNG). Since methane is not widely distributed in Russia, in the future we will talk about propane and equipment for it. Propane is the third most used motor fuel in the world.
Is HBO dangerous in a car?
No, it's not dangerous. A car that runs on gas is safer than a car that runs on petrol. The gas itself is neutral. Its flash point is higher than that of gasoline or diesel fuel. A mixture of gas with air is dangerous, therefore, in a gas cylinder, unlike a gas tank, there is no air, which means there is no explosive mixture. Modern gas cylinders are equipped with four safety valves, which eliminate the possibility of an explosion or gas leakage.
How profitable is the installation of HBO?
Installing gas equipment is beneficial for most cars. This issue is discussed separately in the article "Installation of HBO: advantages and disadvantages." To calculate the benefit from using it on your car, use the HBO installation payback calculator.
What machines is installed gas equipment?
Technical solutions exist for any car: gasoline and diesel, injector and carburetor, with direct injection and distributed, with or without a turbine. The only question is economic feasibility: installation on some cars costs big money and will pay for itself in more than one year.
What is the cost of HBO?
The installation price consists of the equipment price and the labor price. Work in installation centers costs almost the same. The difference depends on several factors:
- car engine: number of cylinders and power
- equipment brand
- reducer type: with combined gas valve or with separate
- type and quality of the injector rail
- type and capacity of the gas cylinder
- material of gas pipelines
- quality of consumables
Some put up expensive equipment and warn about it, others stick to the golden mean, others dump and collect kits from frank trash.
I advise you not to rush to cheap options and carefully discuss the package before installation. The proverb “the miser pays twice” has not been canceled.
How long does the installation take?
Full installation of HBO takes 1 business day.
Can I install HBO myself?
If you have enough skills - you can do it. But such an installation will result in a number of difficulties in the future:
- At the right time, you may not have a special tool
- You will not register the equipment in the traffic police
- It is unlikely that you will configure the software correctly
- You do not pressurize the balloon
- You will not have a manufacturer's warranty on the equipment.
then serious restrictions and I advise you to think before deciding on self installation. Entrust it to an authorized center, where trained specialists will help with the choice of equipment and install HBO on your car according to current rules and standards.
Will the car run on gasoline after installing LPG?
Yes, gas equipment allows you to switch to gasoline manually at any time. When the gas runs out, the machine will automatically switch to petrol and signal this.
For people who travel long distances, a redundant fuel system is an advantage. If you experience problems with one fuel, you can switch to another.
Are there any risks when installing HBO?
When installing HBO by a certified master and his regular maintenance there are no risks of use.
What are the guarantees for gas equipment?
The electronic control unit and gearbox are guaranteed for 2 years or 80,000 km. For other components - 1 year or 75 thousand km.
Does HBO affect engine life?
Gas equipment facilitates the operation of the engine. The use of HBO allows you to increase the service life of the engine and fuel system 1.5–2 times. The effect of gas on the engine is described in the article "Installation of HBO: advantages and disadvantages"
What changes in the car when installing HBO?
HBO components are optional and do not replace gasoline elements. At any time, gas equipment can be removed and the car returned to its original state.
An electronic control unit with sensors and wiring, a gas reducer, a filter and a gas injector rail are installed under the hood. Gas is supplied to the engine through tie-ins in the intake manifold.
Gas lines are supplied to the reducer from the gas cylinder. It is located in the trunk or in the spare wheel well. An external filling device is connected to the gas cylinder. It is displayed in the gas tank hatch, crashes into the bumper, or is carried out under the bumper. A separate article will be devoted to the installation of gas cylinders and VZU
Is it obligatory to register gas equipment with the traffic police?
Yes, according to the law, the installed HBO must be registered with the traffic police. The installation procedure for HBO is as follows:
- Prepare an application for changes to the design vehicle(TC)" in the Department of Registration and technical inspection Vehicles traffic police at the place of registration of the car.
- Obtain permission to install on this application.
- Install HBO in a certified installation center
- With a package of documents from the installation center, obtain from the traffic police "Certificate of compliance of the vehicle design with safety requirements."
This will be a document that the car has been legally converted to gas. A separate article will be devoted to the registration of HBO in the traffic police.
How much will gas consumption increase compared to gasoline?
Depending on the quality of HBO settings and the ratio of propane and butane in the mixture, gas consumption will exceed gasoline consumption by 10-15%.
How does the dynamics of a car on gas change?
Gas burns slower than petrol. Its use reduces the load on the piston group, but causes a deterioration in dynamics. For HBO 2nd generation by 20%, for HBO 4th generation by 2-5% (depending on the degree of compression). We considered this question in the article “Myths about HBO: truth or fiction?”
Why do engine errors occur when installing HBO?
Engine errors appear on different reasons. During HBO operation, they are often associated with the quality of the gas-air mixture: too rich or too lean. To solve the problem, call the service and the master will correct the gas card so that the error does not occur.
How does HBO affect the lambda probe?
HBO does not affect the performance of the lambda probe in any way. Modern gas equipment, on the contrary, uses this data in its work.
How often should I change the air filter after installing HBO?
The procedure for replacing the air filter is set by the car manufacturer and does not change when installing HBO.
How often should I adjust the engine valves after installing HBO?
The procedure for adjusting the engine valves is set by the car manufacturer and does not change when installing HBO.
Periodicity Maintenance gas equipment
Replacing the vapor phase filter - every 10,000 km. at least once a year
Checking the tightness of the system - every 10,000 km.
Filter replacement high pressure- every 30,000 km
Checking and configuring software - if necessary.
MOT should be carried out in a specialized service. The work is carried out by a certified specialist.
Where is it installed gas bottle?
Depending on the design of the car, the gas cylinder is installed in the trunk, in the spare wheel niche (cars), under the body (SUVs), on the roof or on the side (buses, gazelles). Convenient option for cars- in the spare wheel well. So the trunk space remains free. For cars with R13-14 spare wheels, cylinders with a volume of 35 to 42 liters are suitable, for R15-16 from 53 to 60 liters. In sedans with non-folding rear seats it is possible to install a cylindrical cylinder between the wheel arches.
How to find out the remaining gas in the cylinder?
The remaining gas indicator can be displayed on the fuel switch button. The accuracy of the indicator readings is not high, since there are only 5 LEDs on the button. It is more correct to navigate by mileage, resetting it to zero at each refueling. Once you measure the mileage on a full tank, you will know how much fuel is left.
How to fill up with gas?
The car is filled with gas through a remote filling device. It is installed in the trunk, crashes into the bumper, into the gas tank hatch or is mounted under the bumper. Each method has its own merits and demerits. VZU under the bumper - cheap, but it is often in the mud. In the trunk - cheap and convenient, but when the fuel nozzle is disconnected, gas enters the trunk. For a while, the smell of gas remains. VZU in the gas tank hatch - convenient, but expensive. You have to carry an adapter with you and screw it in every time you fill up. Not installed on every car. There is a risk of scratching the car with a loose gun. VZU in the bumper - convenient, cheap, prone to pollution. Depending on the installation budget, I recommend putting the VZU in the gas tank hatch or embed it in the bumper.
Where is the fuel switch located?
The fuel switch button is installed in the car interior to make it convenient for the driver to use. It is possible to install on a false button, on a panel next to the ignition switch or a gearbox torpedo.
What are gas cylinders?
For propane-butane, 2 types of cylinders are produced: cylindrical and toroidal. Cylindrical are installed in the trunk between the arches, and toroidal in the spare wheel well.
The structure and installation of gas cylinders is discussed in a separate article.
How much gas is included in the tank when refueling?
According to safety standards, the gas cylinder is filled to 80%. The remaining 20% is used as a vapor cushion, so when the liquid gas is heated, the pressure in the cylinder is kept normal and it will not explode. A standard 53-liter cylinder holds 42 liters of gas.
How long does it take to fill a balloon?
Before the cut-off, the cylinder is filled in three to five minutes.
How often should the cylinder be checked? According to the current regulations, re-examination of automobile gas cylinders is carried out every 2 years. A certificate of recertification is required to pass the technical inspection.
How is maintenance carried out on vehicles equipped with LPG?
Owners of cars with LPG during the technical inspection need, in addition to standard kit documents to have with you a passport for a cylinder, an act on the installation of gas equipment on a car, a copy of the installer's certificate for the right to install LPG.
What is VZU?

Does gas equipment work in winter?
Yes, in winter HBO operates normally. Read more about this in the article: Features of the use of HBO in the winter.
Why can't you start on gas?
In HBO 4 generations, already evaporated gas is supplied to the nozzles. To convert a gas from a liquid state to a gaseous state, a certain amount of energy must be spent on heating it. When the gas passes from the liquid phase to the vapor phase, the heat energy of the coolant is absorbed (about 40 degrees). Therefore, if you switch to gas on a cold engine, the membranes inside the gearbox will lose elasticity and break. Then the gearbox will fail. For this reason, the transition to gas is carried out at a coolant temperature of at least 45 degrees.
Why is gas more expensive in winter?
In accordance with GOST 20448–80, a distinction is made between summer and winter gas mixtures. Chemical properties propane and butane are different, so in summer they are mixed in proportion: 40% to 60%, and in winter 60% to 40%. Hence the price difference.
HBO does not work. What is the reason?
Gas equipment can fail for various reasons. In order not to guess - contact skilled craftsmen- they will help solve the problem.
