Why is there sludge in the suction valve of a piston compressor?
Thread Content
What is the reason for the sludge on the inlet suction valve of the new hydrogen compressor? Is it caused by the dust in the hydrogen production PSA belt or the lubricating oil in the belt with large oil injection volume? Both the primary and secondary suction valves cause the suction valve to sound. Please give me some advice from seniors.
1; Oil leakage from stuffing box； 2 ； Large amount of oil injection3: The intake valve is not tightly closed
It is usually caused by the large amount of oil injected and the possible impurities in the gas.
The compressor should be analyzed from the outside to the inside. First, check whether the first-level inlet valve contains oil. If the first-level inlet valve contains oil, you need to check whether the first-level air inlet valve is not tightly sealed. If the first-level air inlet valve is good, you must find the cause outside the compressor system. Don't waste time on the compressor. If the first-stage air inlet valve is leaking, gradually eliminate the source of oil from the compressor. However, sometimes there are some accidental factors that cause the device to be oily during initial startup. In this case, there is no way to find out the source. After a while, the problem may have disappeared after a period of observation. .
In addition to the little oil in the oil injector, the most likely source of the liquid is that the liquid separation tank at the inlet of your compressor is not deliquified in time, or the inlet temperature is too high, or the demister of the separator is not good, and the gas is dry. Most of the source of mud is dust in the air. When the suction valve inhales, the dust is also sucked in. The above is my opinion.
First, the amount of oil injected is unreasonable! Too big and so on. The second is media technology issues.
