When the bearing assembly is installed under the liquid slurry pump, the bearing assembly needs to be preheated. Temperature should not exceed 120°C .. The lower bearing adopts double-row tapered roller bearing. Inner ring, outer ring and positioning sleeve are complete sets of components, which are not allowed to be interchanged with corresponding parts of similar bearings. When installing the bearing lower end cover, pay attention to the lip of the lip seal ring in the groove of the lower end cover facing outward. The oil hanger must be in the same direction as in the installation drawing. When installing the labyrinth ring, pay attention to stagger the opening diameter of the labyrinth ring. Although the bearing itself has ensured the axial clearance, the bearing assembly of sewage pump does not need to adjust the clearance during assembly, but after assembly, it is recommended to check the end clearance of the device according to the values listed in the table below. The bearing assembly end clearance bracket, device plate and pump body device are connected with bolts, the split device plate is installed on the periphery of the bracket, fixed with studs, and then the rear guard plate, impeller and pump body are installed. Pay attention to the relative directions of bearing body, bracket, device plate and pump body during installation. The following figure must be complied with to ensure the relative direction between the flowline and the choke. Precautions for Installation of Immersion Slurry Pump and Vertical Slurry Pump The connecting bolts between bracket and pump body must be tightened to check whether the impeller rolls smoothly. In case of friction, the connecting bolts between the bearing body and the bracket can be adjusted by adding cushion blocks. In the final device, the upper and lower filter screens and the discharge pipe are fixed on the device board by screws above the discharge pipe.
