How to deal with the lubricating oil ingress of permanent magnet variable frequency air compressor

时间:2020-08-26| 作者:admin

Hello everyone, today we have sorted out the treatment methods for the lubricating oil ingress of permanent magnet variable frequency air compressors:


1. Automatic sewage solenoid valve:

The bottom of the oil-water separator is equipped with a solenoid valve for automatic sewage discharge. The automatic sewage discharge interval is set to 2 minutes, and the sewage time is set to 5 seconds. Without affecting the normal operation of the air compressor, by increasing the drain time of the separator, the operating time of the permanent magnet variable frequency air compressor is effectively prolonged, and the insufficient operating time of the air compressor is made up. After trial operation, the permanent magnet variable frequency air compressor automatically starts to suppress the pressure, stops at 4.15~4.40MPa, and runs for more than 11 minutes.


2. Replace the pipeline check valve and install the oil-water separator:

Aiming at the problem of the lubricating oil in the air compressor, the technicians replaced the well-sealed pipeline check valve, and installed an oil-water separator with high water removal efficiency after the outlet pipeline of the air compressor. The inside of the oil-water separator is filtered by a precision filter element. After high-temperature compressed air enters the oil-water separator from port a, it passes through cyclone separation, inertial collision separation and fine fiber filtration to directly intercept water and oil in the compressed air, and sewage is discharged from outlet c. The compressed air after water is discharged through outlet b to meet the requirements of high-pressure air.
