Reasons for frequent damage to the air valves in reciprocating compressors
Thread Content
The valve discs of the exhaust valve in our new hydrogen compressor are failing frequently, and it happens at each stage of the exhaust process. Is the problem related to the material of the valve discs or to variations in the manufacturing process?
The valve disc is made of PEEK; I’m not sure if there are any other solutions besides replacing the valve disc in this situation
If nothing else works, how about trying a set of Holbig valve assemblies? Hahaha
Could it be related to the valve lift?
On the left, at the lower level, there are two exhaust valves; one of them has melted due to overheating
Judging from the picture, it seems that the exhaust temperature might be too high, causing the valve plates to soften and deform, which in turn leads to damage.
Are there any more specific compressor operation parameters, such as exhaust pressure and exhaust temperature? Also, what is the temperature measured by an infrared thermometer of the damaged valve during operation?
It’s likely not the high temperature that caused damage to the valve element; once the gas valve is damaged, the temperature rises, and this rise happens very quickly – 20 degrees in just ten minutes
It shouldn’t be a problem with the valve disc material, after all, there are so many stages. . . To analyze the reasons, the problem always lies at the primary level; have you considered the cleanliness of the process gas?
