The slurry pump bearing assembly is also called the rotor assembly. It is a slurry pump accessory assembly. It is an important part of the slurry pump and a transmission power device. The bearing assembly is used to connect the water pump and motor components to form a complete working system. Slurry pump The stability of the pump bearing assembly directly affects the operation and service life of the pump.It is used to transmit power, withstand the force under working conditions and the corresponding axial force, and ensure that the impeller rotates and drives on the same axis.

Slurry Pump Bearing Components

The slurry pump bearing assembly is also called the rotor assembly. It is a slurry pump accessory assembly. It is an important part of the slurry pump and a transmission power device. The bearing assembly is used to connect the water pump and motor components to form a complete working system. Slurry pump The stability of the pump bearing assembly directly affects the operation and service life of the pump.It is used to transmit power, withstand the force under working conditions and the corresponding axial force, and ensure that the impeller rotates and drives on the same axis.

The composition of the slurry pump bearing assembly: mainly consists of 11 parts: 1. Labyrinth sleeve, 2. Oil cup, 3. Butter retaining ring, 4. Bearing body, 5. Bearing, 6. Adjustment pad, 7. End cover, 8 , shaft, 9. labyrinth ring, 10 inch nut, 11. end cover fastening screw

The main function of the bearing body is to support the shaft and the bearing, ensure rotation on the axis, withstand the force, and connect the working body with the power.

The bearings bear the meridional and axial forces to achieve effective rotation. The installation clearances of the bearings of different bearing components in the slurry pump are also different.

The shaft is the center line of pump rotation. The two ends are used to connect the impeller and coupling, connect active components, and transfer power to the working components.

The bearing end cover is used to fix and locate the accurate position of the shaft, adjust the assembly clearance of the bearing, and bear the axial force of the pump

Labyrinth sleeves, oil cups, and labyrinth rings are used to seal both ends of the bearing. One is to prevent the leakage of bearing grease, and the other is to prevent debris and sewage outside the bearing body from entering the bearing. Injecting grease through the oil cup seals and lubricates the labyrinth ring.

The main function of the grease retaining ring is to ensure the normal lubrication of the bearing, block a certain amount of grease, and discharge excess waste oil into the bearing body through the gap between the grease retaining ring and the bearing.

Adjustment pads are used to adjust the bearing clearance of components. They are adjusted according to different standards of different components. The adjustment pads are available in four specifications: 0.5mm, 0.3mm, 0.2mm, and 0.14mm.

The inch nut is mainly used to fasten the drive end labyrinth sleeve and bearings.

Lithium-based grease is used for lubrication of the bearings in the slurry pump bearing assembly.

The installation of bearing components is very important. Improper installation can easily cause the slurry pump to fail to operate, or cause the slurry pump to run unstable, break the shaft, vibrate, etc.
