Due to the long standby time of the twin screw air compressor, the moisture generated by the exhaust gas collects around the pipeline and the check valve, causing the moisture to flow back into the interior of the casing, and the moisture content of the lubricating oil is gradually increased, resulting in an alarm of the high-pressure screw air compressor oil level. Downtime.
When the outlet pipe of the screw air compressor was removed at the stop, it was found that the milky white liquid of the avenue flowed out in the pipe, which indicates that the water content of the exhaust air of the screw air compressor was seriously exceeded.
According to the operation requirements of the twin-screw air compressor, the screw air compressor should have a low running time to prevent the formation of condensed water, because the condensed water will cause rust of the cylinder valve plate, frame parts and the like. Accumulation of condensate in the crankcase may cause an error in the oil level reading.
Water and oil cannot mix, and their co-existence causes the oil to deteriorate quickly. The low running time is generally not less than 10 minutes, which should be sufficient to cause the screw air compressor to heat to the vaporized and condensed moisture.
For the problem of lubricating oil entering the twin-screw air compressor, the technicians replaced the excellent sealing check valve, and installed the oil-water separator with high water-removing efficiency after the screw air compressor outlet pipe. 1 is shown. The inside of the oil-water separator is filtered by a precision filter. After the high-temperature compressed air enters the oil-water separator from the inlet a, it is directly separated by the cyclone separation, inertial collision separation and fine fiber filtration to directly intercept the water and oil in the compressed air. c is discharged, and the compressed air after the water is discharged through the outlet b to meet the needs of the high-pressure gas.
