Influence of interlocking system of ethane compressor on compressor

The influence of ethane compressor interlocking system on compressor needs to be comprehensively analyzed from both positive and negative aspects, as follows:

一、Positive influence (protective effect)

1. Security Interlocking system can monitor compressor operation parameters (such as vibration, temperature, shaft displacement, etc.) in real time, and trigger shutdown protection when abnormal conditions are detected, so as to avoid serious failures or safety accidents caused by continuous operation of equipment under dangerous working conditions.

2. Avoid cascading failures If the key components of the compressor (such as suction valve and sensor) fail, the interlock system can stop to prevent the failure from spreading to other related equipment, thus reducing the risk of damage to the whole system.

二、Second, the potential negative impact (risk)

1. Risk of accidental shutdown If the interlock system is mistakenly triggered due to sensor failure, unreasonable logic design or insufficient maintenance, it may cause the compressor to stop for no reason, interfere with production continuity and increase the start-stop wear of equipment.

2. Limited operational flexibility Partial interlocking logic may limit the adjustment capacity of the compressor. For example, under high pressure or heavy load conditions, interlocking forced shutdown may make the compressor lose its adjustment margin and affect the stability of the system.

3. Increased maintenance costs Frequent interlocking shutdown may accelerate the loss of compressor mechanical parts (such as valves and seals), requiring more frequent maintenance and spare parts replacement.

三、Third, optimization suggestions

1. Reasonably design interlocking logic: alarm and shutdown thresholds should be set according to the actual working conditions of the compressor, so as to balance safety and operational flexibility and avoid excessively conservative or radical interlocking strategies.

2. Redundancy configuration and regular maintenance: Dual redundancy control system (such as PLC or SIS) is adopted to improve reliability, and at the same time, sensors are regularly checked and control software is updated to reduce the risk of misoperation.

3. Fault diagnosis and graded response: set graded alarm instead of direct shutdown for non-fatal anomalies, and give priority to restoring stability by adjusting operating parameters to reduce unnecessary shutdown.

4. To sum up, the influence of ethane compressor interlocking system depends on its design rationality, maintenance level and adaptability to actual working conditions. Correctly configured and managed interlocking system can significantly improve the safety of equipment, otherwise it may become a hidden danger in operation.
