Check whether the noise of the pump is abnormal 1 time / week When the pump is noisy , there are the following reasons :

(1) Air is sucked in by the suction filter

(2) The suction side of the pump sucks in air

 

 

Pressure regulating valve

(1) When there is a time lag from the start of the pump to when the pressure rises and when the noise of the pressure regulating valve increases , disassemble the pressure regulating valve for cleaning

(2) When the tilting speed is too slow , increase the setting of the pressure regulating valve within the maximum operating pressure range of the device . The set pressure does not rise , remove it for cleaning
