A & / L7 U.M

or an armchair (18) and doors (19). Doors (19) are located on the right and left sides of the cabin (12). The outlet of the gas compressor (5) is connected via technological pipelines (20) to the gas storage receiver (6). The shaft (21) is used to connect the connecting device (10), for example, the gearbox, with the internal combustion engine (3), which is the power unit of the vehicle - conveyor (1) of the mobile gas station. The inlet of the gas compressor (5) is connected to the low pressure gas pipeline (22) using a flexible suction pipe (9).

The following is the operating procedure of the claimed device.

This device, namely a mobile gas filling station, is serviced by personnel consisting of a driver - a driver, servicing a conveyor car (1) and a gas compressor (5), and an operator performing work on controlling the technological process for compressing methane and for refueling methane as methane carriers - tankers and vehicles using methane as a motor fuel.

A mobile gas station is heading to the gas station of vehicles using methane as a motor fuel. The refueling place of vehicles can be located in various field conditions, where, often, there are no power lines. Under these conditions, the engine

internal combustion engine (3), which is the power unit of the conveyor car (1) of the mobile gas station, will also be the power unit for driving the gas compressor (5). In addition, the power supply system of the vehicle-conveyor (1) of the mobile gas station will be the only source of electricity for both the control and monitoring systems of the gas compressor (5) and shut-off and control valves (8) of the gas storage receiver (6) and distributors (7) gas of a mobile gas station, and to illuminate the gas station of vehicles using methane as a motor fuel.

When a mobile gas station moves to the refueling site of vehicles using methane as a motor fuel, the conveyor car (1) is controlled by the driver-driver, who, together with the operator, are in the conveyor car control cabin (11) (1).

Upon arrival of the mobile gas station to the refueling site of vehicles using methane as a motor fuel, preparatory work is carried out by personnel to put it into operation. First, the driveshaft of the car-conveyor (1) is disconnected from the main transmission of its drive axles. Then

the propeller shaft of the conveyor car (1) is connected to a connecting device (10), for example, to a gearbox, which, in turn, is connected to a gas compressor (5) via a shaft (21). The grounding of the chassis (2) of the car-conveyor (1) of the mobile gas station is established, with the help of a flexible suction pipe (9) the inlet of the gas compressor (5) is connected to the low pressure gas pipeline (22), the overall dimensions of the mobile gas station are indicated, etc.

After that, the staff of the mobile gas station starts methane refueling both methane carriers - refueling vehicles and vehicles using methane as a motor fuel. It is carried out as follows.

The driver-driver enters the cab (11) of the vehicle-conveyor (1) and is located at his workplace. At the same time, the operator, through one of the doors (19), enters the gas compressor control cabin (12) (5) and shutoff valves (8) of the gas storage receiver (6) and gas distributors (7) of the mobile gas station, sets a comfortable position is the seat or chair (18), is located on the seat or chair (18) and monitors the initial position as controls for the gas compressor (5) located on the remote control (16), and controls (17) for controlling shut-off and control valves (8 ) receiver (6) storage

gas and gas distributors (7), as well as pressure and temperature values of methane in the receiver (6) for gas storage. The operator controls the position of the gas distributors (7) through the inspection window (15) of the rear wall (14) of the double cab (4).

The driver-driver and operator coordinate their actions, maintaining visual and voice communication between themselves through the window (15) of the partition (13) of the double cab (4).

The driver-driver starts the internal combustion engine (3), which is the power unit of the conveyor car (1) of the mobile gas station, and, using the gearbox of the car-conveyor (1), connects the internal combustion engine (3), which is the power unit of the car - conveyor (1) of the mobile gas station, to the gas compressor (5). The connection is carried out by means of a connecting device (10), for example a gearbox, while the connecting device (10), for example a gearbox itself, is connected to the gas compressor (5) via a shaft (21).

Thus, the gas compressor (5) is included in the operation. In this case, the operator, manipulating the controls of the gas compressor (5) located on the control panel (16), maintains the operating mode of the gas compressor (5), controlling its operation parameters at

& th / / RIP H

using control devices located on the control panel (16) for controlling the operating modes of the gas compressor (5).

Methane from the low pressure gas pipeline (22) through a flexible suction pipe (9) enters the inlet of the gas compressor (5), where it is compressed to the pressure stipulated by the methane refueling process of both methane tankers and vehicles using methane as motor fuel . Compressed gas from the gas compressor (5) through technological pipelines (20) enters the receiver (6) for storing gas and, if necessary, to gas distributors (7) for refueling.

Methane carrier - a tanker or a vehicle that uses methane as a motor fuel, drives up to a mobile gas station and stops at one of two gas dispensers (7) for refueling.

After that, the operator through the nearest door (19) goes to the vehicle stopped at one of the two gas dispensers (7) for refueling, and connects the gas dispenser (7) for refueling to the vehicle refueling device.

Then the operator, through the closest door (19), enters the gas compressor control cabin (12) (5) and shut-off and control valves (8) of the gas storage receiver (6) and gas distributors (7) and,

acting on the controls (17) controlling shut-off and control valves (8), it delivers methane from the receiver (6) of the gas storage of the mobile gas station to the cylinders of the refueling vehicle.

In the process of refueling vehicles using methane as a motor fuel, the operator monitors the parameters of the gas compressor (5) using the control devices located on the control panel (16), and the driver, the driver, monitors the parameters of the internal combustion engine (3) , which is the power unit of the conveyor car (1) of a mobile gas station.

After filling the vehicle’s cylinders with methane to the set pressure, the operator leaves one of the doors (19) from the gas compressor control cabin (12) (5) and the shut-off valves (8) of the gas storage receiver (6) and mobile gas dispensers (7) station and disconnects the gas distributor (7) for refueling vehicles from the refueling device of the vehicle. The vehicle is leaving the place of refueling. The next vehicle arrives at the gas station.

At the same time at the gas station several vehicles using methane as a motor

fuel, their refueling is carried out simultaneously on both sides of a mobile gas station.

In the case of low methane consumption for refueling vehicles using methane as a motor fuel, or in the absence of methane consumption for refueling, the gas compressor (5), while continuing to work, will increase the methane pressure in the gas storage receiver (6) to a value equal to the value of the permissible pressure in the receiver (6) for storing gas. The gas storage receiver (6) itself consists of several pressure vessels, which, through shut-off and control valves, are divided into two blocks of pressure vessels of equal internal geometric volume, each of these blocks of pressure vessels being divided into several sections of pressure vessels of different internal geometric volume.

Having received information about the pressure in the receiver (6) for storing gas from control devices located on the control panel (16), the operator gives the necessary commands to the driver - driver through the window (15) of the partition wall (13) of the double cab (4).

In this case, the driver - the driver, using the gearbox of the car - conveyor (1), disconnects the gas compressor (5) from the internal combustion engine (3), which is the power unit of the car 13

conveyor (1) of a mobile gas station. Thereby, the gas compressor (5) is turned off, and methane refueling of both methane carriers - refueling vehicles and vehicles using methane as a motor fuel is carried out due to the methane reserve in the gas storage receiver (6). To maintain the set level of methane pressure in the receiver (6) for gas storage, the driver the driver periodically turns on the gas compressor (5) in the work in the technological order shown earlier.

When refueling both tanker methane carriers and vehicles using methane as a motor fuel in the cold season, comfortable conditions for the operator are ensured by heating the gas compressor control cabin (12) (5) and receiver shut-off and control valves (8) ( 6) gas storage and gas dispensers (7) of a mobile gas filling station with a heating system integrated with the heating system of the cab (11) for driving a conveyor car (1). In addition, the double cab (4) serves to protect the driver - driver and operator from atmospheric precipitation.

After refueling both tanker methane carriers and vehicles using methane as a motor fuel and the need to move the mobile gas station to a new production site

refueling work, preparatory work is carried out by personnel, namely, the gas compressor (5) is turned off from operation, by means of shut-off valves included in the low-pressure gas pipeline (22), the flexible suction pipe (9) is disconnected from the low-pressure gas pipeline (22), the grounding of the chassis (2) of the conveyor car (1) of the mobile gas station is removed, the propeller shaft of the conveyor car (1) is disconnected from the connecting device (10), for example, the gearbox, and the driveshaft is connected to the main gear driving bridges of the conveyor car (1). Gas distributors (7) are fixed in fixed places on the chassis (2) of the vehicle - conveyor (1) of the mobile gas filling station.

After that, the operator enters the car (conveyor) control cabin (11), in which the driver of the car transporter (1) is already located, and the mobile gas station starts moving to the new methane refueling site of both methane carriers, refueling vehicles and vehicles using methane as a motor fuel.
