In practical operations, the outlet pressure of a reciprocating compressor is an important control parameter. What are the hazards of high discharge pressure for the unit, and how can it be avoided during operation or in the design phase?
The outlet pressure is too high, leading to overpressure; it may explode, and the unit is under heavy load. Chain reactions can be set during operation
Reciprocating compressors experience high outlet pressures; exceeding the device’s maximum tolerance or operating under excessive pressure for extended periods can cause fatigue in the equipment, leading to severe damage. A safety valve can be installed at the outlet, or high-alarm and interlock systems can be set up to protect the equipment. It is advisable to establish a safe operating range as well
In design, a pressure interlock value is typically set at the exhaust outlet, and a safety valve is installed. If no action is taken after the pressure interlock alarm is triggered and the pressure reaches the specified level, the safety valve will open to protect the unit
