Interlock settings for reciprocating compressors
Thread Content
Dear experts, could you please advise me on what interlocks should be installed for reciprocating compressors?
You can refer to the relevant design specifications
Overcurrent, low oil pressure. Bearing temperature,,,; if necessary, outlet pressure, inlet pressure, and other required interlocks can also be set. For reference.
It is generally divided into two main categories: the unit itself and the process. The unit itself involves parameters such as bearing temperature, shaft vibration, and lubricating oil pressure； In terms of process issues, the main problems include high separator level and high exhaust pressure.
Oil pressure, circulating water pressure, motor bearing temperature, stator temperature, compressor bearing temperature..
