Abstract: In Xinjiang Kashgar Emergency Power Station, during debugging and operation of the PG9171E gas turbine, two times leakage incidents were occurred in hydraulic oil system of PG9171E gas turbine. The finding process and treating process of the two leakage incidents were introduced. A conclusion was summarized, which is that when the leakage of the hydraulic oil system was occurred, the auxiliary hydraulic oil pump will start automatically; if the outlet pressure of the hydraulic oil system is lower, then the motor current of auxiliary hydraulic oil pump is smaller and the leakage point is closer to the oil pump outlet. The experience can be used as reference for technicians to treat similar problems.
