When the pressure drop of the oil fine separation filter element exceeds 0.08Mpa (the difference between the two pressure gauges: the filter element pressure, exhaust pressure), the oil and gas separation filter element should be stopped and replaced.
This is because the unloading pressure of the machine is taken as the sampling pressure after separation. If the unloading pressure of the machine is set as the rated pressure, the actual load of the motor is the rated pressure plus 0.08Mpa pressure difference, and the motor will be overloaded and overloaded.
The preset value of the pressure difference of the oil fine separation filter element is 100kPa. At this time, the pressure difference of the oil fine separation filter element will not alarm. Therefore, in order to protect the safe operation of the motor, once the pressure difference of the oil pressure gauge is found to be large, the filter element of the oil fine separator should be replaced in time.
