The cause and treatment of common failures of diaphragm pump are:

Failure causes and treatment methods of diaphragm pump pressure deficiency or rise

1, the pneumatic diaphragm pump pressure regulating valve is not properly regulated; the pressure valve is adjusted to 2 of the required pressure and the pressure regulating valve fails; the overhaul pressure is regulated to 3, the pressure gauge is maintained, or the pressure gauge is overhauled or replaced.

Failure cause and treatment method of pressure drop of diaphragm pump

1, oil supply valve oil supply shortage; repair oil valve 2, not enough feed or feed valve leakage; maintenance of feed and feed valve 3, plunger seal leakage; maintenance sealing part 4, diaphragm pump storage tank oil level is too low; 5, adding new oil pump leak or diaphragm damage inspection; replace the sealing pad or diaphragm

Failure cause and treatment method of insufficient flow of diaphragm pump

1, into the discharge valve at discharge; repair or replace the inlet valve 2, diaphragm damage; replace diaphragm 3, speed is too slow, regulation failure; maintenance control device, adjust the speed. The cause of oil leakage fault of diaphragm pump and treatment method, seal pad, seal ring is damaged or too loose; seal pads and sealing rings are adjusted or replaced.
