1 preparation before the start

open to ensure the safe operation of centrifugal pump plant, should be done before starting the necessary checks. First hand the slow turn coupling or pulley, water pump rotation is correct in observing, rotation is flexible, stable, and whether the debris in the pump, the bearing is functioning properly, the belt tension is appropriate; check that all screws are strong; check whether the unit around impede the operation of the debris; Check suction pipe submergence depth is adequate; have to turn off the water valve to reduce the starting load, and timely attention starts to open the valve.

2 running check

boot, you should check all instruments are working properly, stable, and should not exceed the current rating. Pressure gauge should be in the design range; check out the open centrifugal water pump plant is normal, check all parts of the unit for leaks; check compaction of fill, usually a small amount of filler at the appropriate leakage (less than 10 per minute ~ 20 drops), the mechanical seal leakage should not be greater than 10mL / h (about 3 drops per minute); rolling temperature should not exceed 75 ℃; bearing temperature should not exceed 70 ℃ and watch for abnormal noise, abnormal vibration, note that the reduction of water; to adjust the depth of the inlet port submerged; always clean up floating debris on the trash racks; through the belt drive, but also the belt is slipping

3 down and stop after the note

stop off the water valve and then preceded down, to prevent backflow of water, damage to parts; each stop, they should promptly wipe the oil pump and piping to keep the unit clean appearance, to discover hidden; after the winter shutdown, the water should be immediately put the net, to prevent cracking the pump and internal parts; in use after the end of the season, to carry out necessary maintenance

4 centrifugal periodic inspection

ISGD, IRGD low-speed vertical pipe of the pump cycle checkpoint can be divided into the following three types: routine inspections, the use of checks, as described above; monthly check, without removing the case of parts, equipment exterior cleaning and minor repairs, including the temperature of the bearing, shaft seal and cause leakage of electrical insulation and other aspects of the inspection; regular maintenance, including replacement of seal oil, check the pump and motor shaft for wear in the checks, check coupling rubber ring damage control, cleaning mechanical seal, coolant filter and pump filter, check the wear of sliding parts, check parts contact with liquid damage, corrosion, etc.
