Abstract: The low oil pressure of the main equipment lubricating oil system in Wangting Power Plant during start up and operation was introduced. Aiming this problem, the reformation of the main equipment lubricating oil system was carried out, and the reformation process was described in this paper. The problem of low lubricating oil pressure in the same type unit can be solved using the same measures.

Key words: lubricating oil pressure, oil ejector, AC lube oil pump, cavitation, capacity increase
