[Q&A Question 211] November 17, 2016: What are the main reasons for high exhaust pressure at the first stage of a reciprocating compressor? A reference ** will be shown after responding; scoring is achieved by answering the key points. (1) Increased resistance in the exhaust pipeline ； (2) Failure of the lower suction valve ； (3) Poor pre-stage cooling ； (4) Inlet temperature too low ； (5) Internal leakage of the lower piston ring ； (6) The cooling effect of this cylinder is poor.

If it suddenly gets higher. It is usually due to a blockage in the compressor; in such cases, it is necessary to drain the fluid carefully, otherwise it may cause the safety valve of the container with a safety valve that is connected closest to the compressor to activate. When this happens, it can be dangerous, so the fluid needs to be vented through a flare system.
Caused by faulty secondary intake and exhaust valves, resulting in air leakage
High pressure at the primary inlet, large primary compression ratio, backflow in the primary exhaust valve, backflow in the secondary intake valve, improper adjustment of one-to-one or two-to-one ratios, or two-to-two ratios, etc
High back pressure, poor exhaust from the outlet valve, high inlet pressure
What is the main reason for the high discharge pressure at the first stage of a reciprocating compressor? (1) Increased resistance in the exhaust pipeline ； (2) Failure of the lower suction valve ； (3) Poor pre-stage cooling ； (4) Inlet temperature too low ； (5) Internal leakage of the lower piston ring ； (6) The cooling effect of this cylinder is poor
The primary pressure ratio is high, the exhaust valve is faulty, the temperature gauge is faulty, and the flow rate of the circulating water is low
