Analysis of the reasons for shutdown due to low safety oil pressure in centrifugal compressor units
Thread Content
Recently, our company’s gas compression units have shut down three times in a row. The SOE records indicate that the shutdown was caused by a low safety oil pressure, but it is not clear what is responsible for this low pressure. We would appreciate it if experts could help diagnose the issue
Possible reasons for a drop in the pressure of the safety oil leading to shutdown include: 1. Oil pump failure: If the oil pump does not function properly and is unable to provide sufficient oil pressure, this will result in a low pressure of the safety oil. 2. Faulty hydraulic pressure sensor or pressure switch: Incorrect pressure readings or malfunctions can lead to false low-pressure alarms. 3. Clogged or leaking oil lines: Clogged or leaking oil lines can affect the oil pressure, resulting in a decrease in it. 4. Insufficient oil level: A low oil level in the tank or poor oil suction can also cause a drop in oil pressure. 5. Control system failure: Logical errors or faults in the control system can lead to an incorrect determination that the oil pressure is low. It is recommended to check these possible causes, identify the specific issue, and fix it. .
