Abstract

Abstract: In the lubricating oil system of 1000MW steam turbine of a power plant, some air harboured in the outlets of three electric oil pumps. The air formed air resistance, which caused that the output of the oil pump was disappeared and the bushburning accident of the turbine occurred. The accident was introduced. The oil pumps had been reformed two times, and the problem of air resistance was solved successfully. The reasons of the accident were analyzed, providing a reference for related persons.

Key words: air resistance, oil pump, output, two-phase flow
