And so on: Station 2: 1. Furnace area ventilators, centrifugal pumps, and metering pumps. 2. Inspection items: (1) Check whether the temperature of the ventilator casing, the bearing temperatures, as well as the temperatures of the cooling water at the inlet and outlet are within normal ranges. Are there any abnormal sounds? Butterfly valve opening, motor current, vibration, lubricant level, oil quality. (2) Check the pump’s vibration, seal leakage, bearing temperature, for any abnormal noises, as well as the seal oil pressure, inlet and outlet pressures, and motor current. Is the water ring of the pump loose? Check whether the attached pipelines are unobstructed and free of leaks, as well as the lubricant level and quality. (3) Check whether all bolts of the fan and pump are present and not loose. (4) Check whether the standby units and pumps are in good condition and usable. Rotate the shaft 180° within 24 hours.
