The main function of the oil and gas separation barrel of the screw air compressor is to separate the oil and gas mixture in the compressed gas, which is summarized as separation, buffering and storage. Separate the compressed gas from the lubricating oil, make the compressed air cleaner, and the lubricating oil can be reused. Why does the oil and gas barrel of the screw air compressor have water entering? what is the reason? Summarized as follows:
(1) There is a check valve on the outlet pipe of the screw air compressor. The high temperature and high pressure moist air is discharged through the air compressor exhaust valve. After passing through the cooler, it will still carry some oil and water components. Although the second and third of the screw air compressor The interstage cooler and the final cooler are equipped with gas-water separators, which separate the water produced in the compression process, but the actual operation effect cannot reach the ideal state.
Due to the long-term shutdown of the screw air compressor, the water generated by the exhaust gas accumulates around the pipeline and the check valve, causing the water to return to the chassis, and the water content of the lubricating oil gradually increases, resulting in the screw air compressor oil level alarm and failure shutdown. When the outlet pipe of the screw air compressor was removed, it was found that milky white liquid flowed out of the pipe, which also showed that the moisture in the exhaust of the screw air compressor was seriously exceeding the standard.
(2) According to the operating requirements of the screw air compressor, the screw air compressor should have a small operating time to prevent the formation of condensed water, which will cause the cylinder valve plate and frame parts to rust. Accumulation of condensate in the crankcase may cause incorrect oil level readings.
Their coexistence caused the oil to deteriorate rapidly. The smaller run time is generally not less than 10 minutes, which should be sufficient to heat the screw air compressor to the vaporized condensate.
Know the reasons for the failure of the screw air compressor, don't panic. When the air compressor equipment fails, experienced people can judge by themselves and cooperate with the after-sales service personnel of the air compressor manufacturer to quickly solve the problem, so that the air compressor can be put into normal production again.
