In order to ensure the normal operation of the centrifugal slurry pump after starting and extend the service life of the centrifugal slurry pump, Shijiazhuang Stone Pump slurry Pump Pump Industry Co., LTD., some necessary checks on the equipment of the centrifugal slurry pump before starting are as follows:

1) Check whether the anchor bolts are tightened.

2) Check whether the bearing temperature measuring components are normal (desulfurization pump is equipped with temperature measuring components).

3) Check whether the motor insulation is normal.

4), check whether the bearing room is filled with oil, mechanical oil is divided into 32#, 46#, 68# (32# is preferred). When mechanical lubricating oil is filled, the oil level should be flush with the center line of the oil mark (the initial filling should be slightly higher than the center line of the oil mark);

Grease lubrication is not added at the first start, and 2# or 3# lithium-based grease is added according to the product instruction manual

5), check whether the mechanical seal limit plate is open. Note: Slurry pump equipped with mechanical seal must open limit plate before starting pump!

6), rotating pump shaft (including motor and adjusting device) whether there is tight and friction phenomenon, there are abnormalities to be eliminated. Method: Rotate the pump shaft 360℃ according to the direction indicated by the pump arrow. When there is friction in the pump chamber, adjust the axial clearance of the pump shaft to eliminate it.

7), check and confirm whether the rotation direction of the motor, diesel engine, reducer, etc. is consistent with the rotation direction specified by the pump, remember: the pump is not allowed to rotate in the opposite direction! (When the motor is started by buck and then switched to normal pressure operation, whether it is started by buck or normal pressure operation, the rotation direction of the motor should be consistent with the direction specified by the pump). In addition, when checking the rotation direction of the motor, diesel engine, etc., it should be tested separately, and must not be tested with the pump after connection.

8) Check whether the shaft seal water pump is normal, including the pipe and valve of the shaft seal water pump, to ensure that the water pressure and flow of the shaft seal water meet the requirements of the product instruction manual.

9) Check whether the valves of the centrifugal pump system are flexible and reliable.

10), check whether the motor and the pump shaft are concentric: the concentricity of the coupling, reducer, etc. with the motor and the pump shaft should conform to the specified value in the product manual.

11) Check whether the pump groove wheel driven by the triangle belt is installed correctly, and ensure that the pump shaft is parallel to the motor shaft and the two wheels are aligned.
