Maintenance of multistage centrifugal pump

(1), and combined examination of multistage centrifugal pump pipeline loosening. Turn the multistage centrifugal pump with the hand, look at the multistage centrifugal pump is flexible.

(2), join the bearing lubrication oil to the bearing body, observe the oil level should be the subject of the center line of the oil, lubricating oil should be replaced or supplemented.

(3) the drain plug multistage centrifugal pump, screw, filling water (or lead paste).

(4), close the outlet pipeline valve and outlet pressure gauge and vacuum gauge.

(5), to move the motor, when the motor turning right or not.

(6), multistage centrifugal pump long-term disabled, the pump all apart, dry water, the combination of rotating parts and apply grease to pack.

(7), try to control the range of specified multistage centrifugal pump flow and head on the plate, in order to ensure the multi-stage pump at maximum efficiency operation, to maximize energy saving effect.

(8), multistage centrifugal pump during operation, the bearing temperature should not exceed the ambient temperature 35C, the highest temperature shall not exceed 80C.

(9), such as the discovery of the multistage l centrifugal pump abnormal sound should stop and check the reason.

(10), multistage centrifugal pump to stop use, turn off valve, pressure gauge, and then stop the motor.

(11), multistage centrifugal pump in the first month of work, replacement of oil by 100 hours, after every 500 hours, oil change time.

(12), multistage centrifugal pump often adjust the packing gland leakage, ensure the normal packing chamber (to drop out as appropriate).

(13), periodically check the wear of multistage centrifugal pump sleeve, wear in time after a larger replacement.

(14), multistage centrifugal pump used in the winter season, parking, the pump body lower drain plug unscrew medium on the net. To prevent the cracking.

(15), activate the motor, when the normal operation of the multi-stage pump, open the outlet pressure gauge and vacuum pump depending on the show after the appropriate pressure, and gradually open the valve, and check the motor load conditions.
