29.What is the relationship between the replacement of oil separator and its oil pressure gauge?


       When the pressure drop of the oil separator filter element exceeds 0.08MPa (the difference between the two pressure gauges: the pressure before the filter element and the exhaust pressure), the oil separator filter element should be stopped and replaced.

        This is because the unloading of the machine is the pressure after separation as the sampling pressure, if the unloading pressure of the machine is set to the rated pressure, the actual load of the motor is the rated pressure plus the pressure difference of 0.08MPa, the motor will be overloaded.

        The preset pressure difference of oil separator is 100 kPa, and the pressure difference of oil separator will not alarm at this time. Therefore, in order to protect the safe operation of motor, the filter element of oil separator should be replaced in time when the pressure difference of oil separator is large.
