How to run a petrol-generator gasoline engine to start the air system?

The operating conditions of the gasoline generator start-up air system for gasoline generators are as follows:

1. Each gasoline-powered gasoline engine is equipped with a WP 65L-100 electric compressor, which is used to supply and supplement compressed air to the starting cylinder. It can automatically or manually remotely control inputs and remove compressors.

When the compressor is started, the electromagnetic trap IXJP.OANO01-KA01 is simultaneously powered (closed) after 15 seconds of delay, and then drained every 15 minutes for 15 seconds; otherwise, when the compressor is removed, the trap is simultaneously Power off (on). Hydrophobicity drains through a hydrophobic tube to an oily wastewater collection and discharge system (0 meters from UBS plant).

When the compressor/air dryer is started, the electromagnetic trap 1XJP.OAHO01-KA01 is closed; conversely, when the compressor/air dryer is cut off, the trap is opened. The valve was turned on every 5 minutes during the operation of the compressor for approximately 15 seconds (with a harsh air whistling sound). Its opening time can be adjusted on the spot. Similarly, the hydrophobic drains to the oily wastewater collection and drainage system via a hydrophobic tube.

2. Each emergency gasoline engine is equipped with three compressed air starting cylinders. Starting the cylinder can ensure that the gasoline engine will be started six times in a row. Safety valves, pressure gauges, compressed air inlet and outlet shut-off valves and check valves, and drain valves and lines are installed on the cylinders. Compressed air pressurized by the compressor passes directly into the three startup cylinders via the air drying device and the startup cylinder intake valve IXJP.0AA012,022,032. The compressed air in the start cylinder 1XJP. 0BB0I0, 020, 030 passes through the main starting valve, starts the air distributor into the cylinder starting valve, the hydraulic pressure regulator and the speed regulator.

A check valve is installed on the inlet and outlet lines of each starting cylinder. They ensure that the three starting cylinders are in exactly the same and independent position. Thus, the pressure in each starting cylinder can be monitored by the pressure gauges 1XJP.0CP501, 502, 503 while the system is running.

1, start the cylinder trap 1XJP.0AA511,521,531

The three manual valves are installed at the lowest point of the starting cylinder. When the gasoline engine is running, the trap should be closed. In order to drain the starting cylinder, the valve water valve is opened in turn for about 5 seconds and then closed again. Drainage occurs approximately every two weeks.

2, start the gas bottle hydrophobic mother tube drain valve 1XJP.0AA501

The water drained directly through the pipeline to a 0 meter oily waste water collection room. The manual trap should be closed while the gasoline generator is running. It is only opened when the starting cylinder is drained. It should be closed immediately after the water is finished.

3, start the gas cylinder outlet female steam trap 1XJP.0AA502,503

The two valves are installed in the room 11UBS04.20, which starts the lowest point of the air outlet main pipe line, and drowns the water directly to the room floor. When hydrophobic, first open 1XJP.0AA503, then open valve 1XJP.0AA502 for about 5 seconds. After the completion of the draining, the sequence of valve closing is exactly the same at the time of opening. In addition, the valve is also used for depressurization of the outlet pipe of the gas bottle (at this time, the gas bottle outlet valve should be closed, and the compressor power should be removed to prevent the compressor from starting).

Third, control solenoid valve IXJP.0AA041A (its position switch is IXJP.0CG042) is a three-way valve (3-way valve), when there is a start signal, it is turned on at the same time, compressed air can pass through and the main start Valve 1XJP.0AA041 (the position switch is 1XJP.0CG041) turns on.

After the main starting valve is opened, all the compressed air is sent to the cylinder starting valve through the starting air distributor. When the cylinder starting valve is opened, the compressed air enters the cylinder and pushes the piston to move. The start air distributor is installed on the gasoline engine. The cam of the gasoline engine assists with the half speed of the engine. Its function is to send compressed air into the cylinder in sequence according to the order of firing during the start-up process. The other compressed air after the main starting valve passes through the check valve (1XJP.0AA642) and the restrictor (1XJP.0AA043, restrictor) and then is injected into the air inlet system to compensate for the insufficient air flow during the swivel. The flow restrictor can adjust the air flow into the air intake system.

Once the gasoline generator has ignited and reached the minimum speed (350 rpm), the control circuit is interrupted by the relay of the speed sensor (1XJY.0CS003/004/005) and the control solenoid valve 1XJP.0AA041A is closed. This also causes the source of power to start the valve to be shut off and shut off, and the compressed air start sequence is interrupted.

The control solenoid valve has a manual opening knob, and the main activation valve also has a manual pressure lever to open the main activation valve. (Their role is to start the gasoline generator in an emergency.)

If the gasoline engine does not ignite within 6 seconds of start-up, a "start failure" signal is sent. This is the control of the solenoid valve being shut down.
