        A total of 9 common faults are summarized,

        The first one is that when the power consumption of the slurry pump is too large, the reason for this phenomenon is that the packing is too tight, the packing chamber is heated, the water supply is too large, and the impeller is worn. These reasons will cause the slurry pump to fail. Too much power.

        The second point is that when the sound in the slurry pump is not like the usual sound, it is abnormal, and the slurry pump does not produce water. The reasons for this phenomenon are that the resistance of the suction pipe is too large, the water absorption height is too large, and air enters the water absorption These phenomena are the reasons for the abnormal sound of the slurry pump.

        Point 3: When the flow rate of the slurry pump is lower than the design flow rate, the reasons for this phenomenon are that the impeller is blocked, the speed of the slurry pump is not enough, and the clearance of the sealing ring is too worn. These reasons are the flow rate of the slurry pump. flow below design.

        The fourth point is that the bearing is short of oil or the oil viscosity is too high to affect the lubrication, the bearing wear gap is too large, and the slurry pump and the motor are not concentric, and the slurry pump bearing will heat up.

        The fifth point is that when the outlet pipe resistance is large, the steering is wrong, the impeller is blocked, and the speed is not enough, these reasons will cause the slurry pump to produce little or no water.

        The sixth point is the abnormal vibration of the slurry pump. The reasons are that the slurry pump shaft and the motor shaft are not concentric, the impeller is unbalanced, and the bearing clearance is too large. These are the reasons for the abnormal vibration of the slurry pump.

        Point 7 is that the installation of the slurry pump and the motor is not concentric, and the bearings of the slurry pump or the motor are worn, which causes excessive noise of the slurry pump.

        Point 8: When there is air in the pump body of the slurry pump, air leakage occurs in the suction pipe and the surface pipe, the slurry pump will not absorb water and the pressure gauge will jump violently.

        The ninth point is that the bottom valve of the slurry pump is not opened or is seriously blocked, the resistance of the suction pipe is too large, and the suction height is too high. These reasons are that the vacuum gauge of the slurry pump indicates a high vacuum, and the slurry pump is still Does not absorb water.
