high discharge temp of air compressor
high discharge temp of air compressor
(OP)
Hi all
we have a khosla make air compressor installed in our unit. Its a two stage double acting reciprocating compressor. Discharge of 1 st stage is passed through a water cooled inter cooler and outlet is fed to second stage.
Generally we encounter with 2nd stage high temp problem while 1st stage outlet temp remains within limit. jacket cooling water inlet and outlet temp are also within limit.We have a doubt that that may be some scale formation in jackets and piping. We clean the jackets during the scheduled preventive maintenance done every six month. Now should we go for cleaning of piping also??

RE: high discharge temp of air compressor
Fouling in the interstage cooler can also lower second stage suction pressure.

RE: high discharge temp of air compressor
1st stage discharge pr. is on higher side instead. outlet temp of inter cooler is also within limits so fouling in inter cooler can not be thought of.
At least one thing is clear that if the suction pr of a reciprocating compressor is low, discharge temp will be high.
right??

Is your air compressor issues (the high temperature) ever seen before at summertime higher water cooling temperatures?
Anything different in other parts of your cooling system? you mentioned a 6 month cleaning of the AC HX, what about the rest of the system: cleanliness and flows the same elsewhere?
