Abstract

Abstract: Abstract:In debugging process of the 600MW steam turbine oil system of a newly-built power plant, several faults occurred, which include that the unit tripped after shutdown of highpressure startup oil pump, the lubricating oil pressure dropped too much in interlock test of AC oil pump and DC oil pump, the turning gear of the jacking oil system disconnected, the sealing oil entered into inside generator, the sealing oil differential pressure valve damaged, the temperature of highpressure fire resistant oil was too high and others. The faults were analyzed and treated, and better effects were obtained.

Key words: Keywords:600MW steam turbine, oil system, fault analysis, treatment method
