Reasons for water ingress in the oil and gas cylinder of the screw air compressor

The outlet pipeline of the screw air compressor is equipped with a check valve. The high temperature and high pressure humid air is discharged through the exhaust valve of the screw air compressor, and a certain amount of oil and water components are still entrained after passing through the post-stage cooler. Although the two-stage, three-stage intercooler and final-stage cooler of the screw air compressor are equipped with gas-water separators to separate the water produced during the compression process, the actual operation effect is not ideal. Due to the long shutdown time of the screw air compressor, the moisture generated by the exhaust gas gathers around the pipeline and the check valve, causing the moisture to return to the inside of the chassis, and the moisture in the lubricating oil gradually increases, z* finally causing the oil level alarm of the high-pressure screw air compressor, Downtime. When the screw air compressor was shut down and the outlet pipeline was disassembled, a large amount of milky white liquid was found to flow out of the pipeline, indicating that the water content of the screw air compressor exhaust was seriously exceeded.

 According to the operation requirements of the screw air compressor, the screw air compressor should be equipped with z*low running time to prevent the formation of condensed water, because the condensed water will cause the cylinder valve plate, frame parts, etc. to rust. Condensation buildup in the crankcase can cause incorrect oil level readings. Water and oil cannot mix, and their coexistence will cause the oil to deteriorate rapidly.  z* The running time at low speed is generally not less than 10 minutes, which should be enough to heat the screw air compressor to vaporize and condense moisture.
