Abstract: The fault of pressure slowly decreasing occurred in the 300MW turbine EH oil system of Huadian Weifang Power Generation Corporation Limited. The factors, which probably influence on the pressure, were confirmed and eliminated one by one, and relevant measures were proposed. After a minor overhaul, the unit was startedup again, and the EH oil pressure and the oil pump motor current became normal.
