Transformation of Double End Face Mechanical Seal Cooling System of Export Pump
An offshore platform's export pump adopts the mode of"one in use and two backup",in which the double end face mechanical seal of export pump A uses seawater cooling method.In order to solve the problem of mechanical seal leakage caused by this cooling method,it is proposed to transform the double end face mechanical seal cooling system of export pump B/C into a pressurized lubricating oil cooling mechanical seal and use a cooling column to cool the circulating lubricating oil.A complete set of cooling system with functions such as liquid replenishment,pressure maintai-ning,pressure boosting,and alarm is designed to ensure the normal and smooth operation of the ex-port pump.
