What are the reasons for the increase in exhaust temperature and pressure in a reciprocating compressor? ?
Thread Content
We are currently using a symmetrically balanced reciprocating compressor with three stages of compression, model 2D32-3.67/37-225. In recent days, we have noticed a decrease in the exhaust pressure of the first stage, while the exhaust temperature and pressure of the second stage have increased; everything else is normal Is it suspected to be a problem with the primary or secondary exhaust valves? Everyone, please give some feedback and analyze what exactly is going on ? ?
Check the valve springs for level 1 and level 2
The leakage in the first-stage exhaust valve’s drain pipe is not proper, which results in an increased second-stage pressure ratio, or a decreased first-stage pressure ratio – with the second-stage pressure ratio becoming higher!
Measure the temperature of the valve; this provides a straightforward way to determine whether there is a problem with it； Also check whether there are any significant changes in the material components.
The primary exhaust or intake valve is leaking, and the tertiary intake valve is leaking.
Fault in the first-stage exhaust valve or piston leakage; fault in the third-stage intake valve; leakage in the second-stage exhaust valve
Thank you all for your responses. After opening the primary exhaust and the secondary exhaust, it was found that the bolt securing the valve positioning guide rod of the secondary exhaust was broken. The secondary exhaust valve has now been replaced, and no tests have yet been conducted to check for any abnormalities
