The problems resulting from quality deterioration of fire resistant oil

such as corrosion of the servo valve due to resistivity of the said oil being somewhat lower

and warning from the outlet strainer of EH Type oil pump being frequently occurred in Yimin Power Plant

have been analysed. After finding out the causes

the said fire resistant oil has been treated using the strong palarity silicon aluminium regenerative facility manufactured by The Thermal Power Research Institute under State Power Corp

and complementary measures

namely replacing the strailler

enhancing oil temperature in operation

and eliminating local overheat points in the fire resistant oil system

have been taken to make the said problems to have been resolved.
