CENTRIFUGAL COMPRESSOR

CENTRIFUGAL COMPRESSOR

CENTRIFUGAL COMPRESSOR

(OP)
DEAR COLLEAGUES,
WILL YOU PLEASE EXPLAIN FOLLOWING THREAD.

CAN WE RUN CENTRIFUGAL COMPRESSOR BY THROTTLING SUCTION AND DISCHARGE VALVES
WITH REGARD
SAFDAR TOOR

RE: CENTRIFUGAL COMPRESSOR

Yes, throttling centrifugal compressors with either suction or discharge valves is done.  Speed is more commonly used but since you didn't mention it, I'm assuming your compressor is a fixed speed unit.  

In either case, you need to ensure you remain within the compressor's allowable operating envelope for flow, head, pressures, etc.

RE: CENTRIFUGAL COMPRESSOR

Adding to TD2K point (but by no means the ultimate word):
In case you throttle the compressor discharge, beware of going below the recommended min flow, a safety relief valve bypassing back to the supply should be installed to avoid damage to the compressor...and in any case recirculation cannot be permanent due to overheating.

RE: CENTRIFUGAL COMPRESSOR

Again forgot something to tell TD2K. (There is some addition to your point again)

Cheers,

RE: CENTRIFUGAL COMPRESSOR

Always know I can count on you Quark
