Operation steps of slurry pump

Operation steps of slurry pump:

First,  pour the oil dimension into calcium-based grease.

Second, check whether the motor rotation direction is correct.

Third, observe whether  the pump installed base is stable, all the parts bolts are tightened.

Fourth, when the pump stops working, you should first stop the motor, and then close gauge cocks. Fifth,  pump stops running for a long time, the pump should be disassembled, wipe clean, coated with anti-rust oil for safekeeping Classification according.

Sixth, check whether the shaft has been adjusted to the gap (no friction sound can flip couplings).

Seventh, the starter motor, open gauge cocks, when the pump is working at full revolutions, the regulator valve opening to the desired range.

First, the vortex solid hard shell sediment blockage of measures you can clear the blockage.

Second, the shaft and Tim bin different axis, mainly due to processing error, incorrectly installed. You should check after-installation for proper installation. Such as sealing water ring badly worn, then replace new water ring. Such as sealing water tube blockage, water can not enter the packing seal packing wear and tear caused by the middle of fast, resulting in leakage of material. You should deal with clogged pipes for dredging and maintaining seal water clean.
 
Third, the media uneven density. Medium density cause uneven pump just started when vibration occurs when the pump is normally turned on, the pump vibration will disappear, this situation do not need treatment, just before driving, people should pay attention to the media with high-pressure wind ;

Fourth, the installation of the pump is not level. The installation and operation of the pump should be checked during the level.

Fifth, cavitation, which makes the pump impeller imbalance. Mounting height should be reduced,gravel pump industry transfer a small water valve, reducing imports resistance.

Sixth, uneven suction pipe inlet.  People should improve feed pump , enhance the uniformity and stability of the intake.

Seventh, the pump bearing clearance is large. Bearing clearance too large will make the vibration of the pump, in the daily operation of the device people should always
observe the pump and found that the pump shaft and motor shaft misalignment or bearing damage should be promptly treated.

Eighth, the motor shaft and pump shaft asymmetric or are not parallel. People should adjust  the motor shaft or shaft, if there is deformed or bent shaft people should replace the shaft directly .

Ninth, the bearing assembly is unreasonable. The bearing and shaft reload, or replace bearings.

Tenth, poor lubrication. Too little can lead to excessive impurities bearing life short, API standard mean the bearing should be removed for cleaning before use.
