As the feed pump has its own lubrication system, axis instructions and motor cold room, speed feed water pump has a sealed water device, so in addition to general inspection of the pump, it should also check: (1) axis indicator is normal; (2) ) Cold room out, into the water gate position, the fuel tank level, oil quality, auxiliary pump work, the oil pressure is normal, the oil cooler, inlet oil temperature and water temperature, sealing water pressure, hydraulic coupling, spoon Tube opening, working oil cooler inlet and outlet oil temperature. For the steam-driven feed pump group should also check: (1) the system no oil leakage, leakage, leakage phenomenon; (2) adjust the system flexibility, no card astringent, swinging phenomenon; (3) small motor bearing vibration within the specified range ; (4) adjust the hydraulic pressure within the specified range; safety control hydraulic pressure within the specified range; (5) lubricating oil pressure, lubricating oil temperature normal; bearing oil return temperature within the normal range; (6) bearing metal temperature within the normal range; filter differential pressure within the normal range; (7) a small shaft seal pressure within the normal range; Exhaust exhaust temperature within the specified range; (8) a small machine vacuum normal .
