The gas pressure regulator includes a micro air pump and a control valve. The control valve consists of a one-way valve and a pressure limiting valve. The air inlet of the one-way valve is connected to the air outlet of the micro air pump through an air delivery pipe, and the air outlet of the one-way valve is connected to the air inlet pipe. The outlet pipe sleeved in the inlet pipe is communicated with the pressure limiting valve.

How does the gas pressure regulator work?
The function of the gas pressure regulator is to keep the pressure in the oil circuit constant. If the oil pressure is too low, the fuel injection of the injector will be too weak or not. If the oil pressure is too high, the oil circuit will be damaged or the injector will be damaged. There is a diaphragm inside the pressure regulator, which plays the role of controlling the opening and closing of the pressure valve. When the oil pressure is lower than a certain value, the pressure valve is closed, and the pressure in the oil circuit is increased by the oil pump. The diaphragm is opened, and the over pressured fuel flows back to the fuel tank through the return line, and the gas pressure regulator acts as a decompression.
What should be paid attention to when operating the gas pressure regulator?
1. Keep the lubricating oil in the oil pool within the range of the scale. Before the operation of the gas pressure regulator, check that the oil amount in the oiler should not be lower than the scale line value.
2. Check whether the moving parts of the gas pressure regulator are flexible, whether the connecting parts are tight, whether the lubrication system is normal, and whether the motor and electrical control equipment are safe and reliable.
3. Before operating the gas pressure regulator, check whether the protective devices and safety accessories are in good condition.
4. Check whether the exhaust pipe is smooth.
5. Connect the water source, open each water inlet valve, and make the cooling water unblocked.
What should I pay attention to when restarting the gas pressure regulator if it is not used for a long time?
When operating the gas pressure regulator, it should be noted that before starting for the first time after long-term deactivation, it must be checked by cranking, and pay attention to whether there is any phenomenon such as collision, jamming or abnormal noise.
The gas pressure regulator must be started in a no-load state, and after the no-load operation is normal, the air compressor will gradually enter the load operation.
After the gas pressure regulator is operating normally, you should always pay attention to various instrument readings and adjust them at any time.
The gas pressure regulator has achieved an irreplaceable position in car production. DEM Machinery Co., Ltd. is committed to providing various bending and rolling machines of high quality for all customers from all over the world.
