Shenzhen air compressor（1）Confirmed the cause of the pressure drop and instability due to the host or Fusheng air compressor accessories. First turn off the host, port and disconnect the air compressor parts with the host, observe the output pressure indicator (other with no pressure gauge pressure gauge connection). If the pressure is normal, you can determine the gas leak inside the host, or Fusheng air compressor parts air failure. On the mainframe of the gas leak, first open the chassis, through the sound and fingertips feel to find the leak site, I encountered the host rubber tube aging rupture, 2 cases of new port model crack leakage, silicone tube corresponding specifications rather than crack rubber tube can be eliminated leakage.

（2）Air compressor gas leak repair must open the air compressor hood. Listen to leaks where, and then the feeling of the fingers, the focus should be on the connection filter bottles, filters, gas transmission tube and two, etc., Fusheng air compressor parts leak I encountered the failure, Crack, filter the bottom of the bottle aging, so that the air is removed after the failure of the filter bottle. Another example is Fusheng air compressor parts outlet fittings automatic shut-off device has cracks, vvvv_vcze2 AB glue will crack repair, adjust the return spring tightening, so that back to the middle, will lose balance state can be restored in the air. An example is the bear 750psv machine Fusheng air compressor parts pressure regulating system drain completely blocked, the release valve reverse leakage. Release the valve button after the removal of foreign body, observe the output pressure gauge pointer, restore to the best output pressure can be put into use.

Shenzhen air compressor（3）Eliminating the leakage point The output pressure is still unstable and may be a problem with the piston ring or the compression pump itself. Compress the pump to remove the oil and replace the piston ring. The process of replacing the piston ring is very complicated and professional training should be done at the staff. If the replacement piston ring failure disappears, it is the piston ring aging, so that between the ring and the cylinder. Replace the piston ring pressure is still unstable phenomenon, which of course is in the drum itself, the entire compression pump must be replaced. Particular emphasis is placed on a compression pump should pay attention to several interface strength and sealing, focusing on the force is not too much, resulting in other damaged parts. For example, some rubber elbows should be slowly rotating and flexible, and then slowly turn, otherwise likely to cause fracture.
