Cause analysis and improvement measures of oil system faults in feed water pumps turbine

Abstract

Abstract:

Taking 2×330MW units of a company as an example, the problems that one of the main oil pumps tripped during the operation of feed water pump turbine and another feed water pump turbine tripped during its abnormal joint since the pressure of lubricating oil was low are analyzed. Through theoretical analysis and field test, the reasons for the low joint oil pressure of the oil pump are found out, and the corresponding improvement measures are implemented to improve the safety of the unit operation.

Key words:

feed pump steam turbine, oil system, oil pump, tripping, lubricating oil
