What caused the oil leakage of Dongfeng Tianjin solenoid valve?

What causes the solenoid valve to leak oil?

First, the damage of the solenoid valve diaphragm. Close the valve in front of the solenoid valve distribution assembly and open the solenoid valve for inspection. If the solenoid valve diaphragm is damaged, it must be replaced.

Second, when there are some impurities, such as welding slag and rust, on the air outlet surface and gasket of the solenoid valve diaphragm, the solenoid valve will leak if they are not tightly sealed. At this point, you must open the solenoid valve to clean up the debris. In the process of installing bag filter, the compressed air pipeline should be ventilated and purged to remove impurities such as rust and welding slag, and then the pulse valve and gas distribution package should be installed, which can effectively avoid the electromagnetic valve from leaking due to impurity blockage.

Third, there is a solenoid valve. If the nozzle of the airbag leaks, compressed air will directly enter the blowpipe without passing through the solenoid valve and leak. At this time, it is necessary to change a blowpipe or repair it as soon as possible.
