Analysis of the causes of compressor surge
Thread Content
Analysis of the causes of compressor surging. Below is an analysis from the question bank; please provide a detailed explanation, especially from the perspective of operational management. 1. Handling of unit surge caused by equipment failures and external factors: Excessive seal gap at the shaft ends between unit sections; leakage or activation of safety valves between sections; internal leakage in the heat exchangers between sections; lag in the turbine control system; condenser failures; fluctuations in main steam pressure and temperature. 2. Handling of unit surge caused by operational and management issues: Excessively high system pressure; the unit operating beyond its capacity; the anti-surge system being in manual mode; improper adjustment of the unit; poor coordination between on-site operations and central control; clogging of the inlet filters; blocked passages in the anti-surge valves
These things are only useful for exams; to truly learn and master something, it’s essential to study its underlying principles. It is also necessary to study specifically based on the type of characteristics and driving mode of the compressor, for reference.
