Compressed air contains moisture
Thread Content
The compressed air is delivered to the user through the dryer. During use, the user discovers that the compressed air contains a large amount of water. The operator discharges sewage once an hour. The valve is normal and there is no alarm.
Check to see if it interacts with water
Check the desiccant to see if it is missing or expired
If the amount of condensed water discharged does not increase significantly, it should be a problem with the drying system. Check the adsorbent and switching system valves for internal leakage. This has nothing to do with the compressor.
The poster’s statement: Users discovered during use that it contained a large amount of water. There are two situations. One is that the amount of water suddenly increases, and the other is that after a gradual process, it is later found to contain a large amount of water (not found before). 1. For one, the reason is [1] The valve switching system is broken, the actuator no longer operates, and in-depth inspection is required. ； 【2】If there is a buffer tank downstream of the compression heat dryer, check whether there is water in the gas storage tank. There may be a lot of water, or it may be full. 2. Regarding the second issue, [1] the life of the desiccant has expired. ； 【2】The processing gas volume, that is, the load increases ；
Cold dryer + adsorption drying, the effect will be better
Just measure this and you will know the dew point coming out of the dryer. If it is high, it should be more of a problem with the desiccant.
Check whether the valve switching of the dryer is normal, whether the internal molecular sieve is replaced in time, whether there is a large water source next to the compressor, and whether there is water inside the filter that has not been drained cleanly?
It seems that the desiccant has failed. Has the molecular sieve been replaced during use?
The lifespan of alumina or molecular sieve has expired
