1. Automatic sewage solenoid valve:
An automatic sewage solenoid valve is set at the drain port at the bottom of the oil-water separator. The interval time of automatic sewage discharge is set to 2min and the sewage discharge time is set to 5s.Without affecting the normal operation of the permanent magnet variable-frequency air compressor, the operation time of the permanent magnet variable-frequency air compressor is effectively extended by increasing the blowdown time of the separator, so as to meet the minimum operation time requirements of the air compressor.After trial operation, the permanent magnet variable frequency air compressor starts and presses down automatically.4.15~4.40 MPa stop and run for more than 11 min.
2. Replace the check valve of pipeline and install oil and water separator:
In view of the problem of lubricating oil inlet of the air compressor, technicians replace the check valve of the pipeline with good sealing, and install an oil-water separator with high water removal efficiency after the outlet pipeline of the air compressor.Oil-water separator inside the calculation precision filter filter, high temperature of the compressed air from imported a after entering oil-water separator, the cyclone separation, inertia collision separation and carefully fiber filter, the oil and water from compressed air directly to intercept down, through c discharge outlet, in addition to the compressed air after water through exit b eduction, meet the needs of high pressure gas.
