Abstract

Abstract: Aiming at the fault of oil pressure falling in unit No.2 of Baotou Power Generation Branch of Inner Mongolia Huadian Energy Corporation Limited, under the premise of safety of main machine, the lubrication oil system test was carried out to make prejudgment. And after the unit shutdown, the oil system was inspected, and it was found that the power oil inlets of oil ejectors No.1 and No.2 of main machine lubrication oil system of unit No.2 were blocked by foreign bodies. The reason of lubrication oil pressure falling was found, the problem was solved successfully. 

Key words: lubrication oil, oil ejector, oil pressure, blockage
