Overhaul Items and Maintenance of Heavy Duty Slurry Pump

1. Wear detection for heavy duty slurry pump?

Check the wear depth of the shaft hole. If the wear depth is less than 4mm in the diameter direction (i.e. less than 2mm in the radius direction), the position to be repaired shall be polished and deepened with an electric tool. Note: the surface should not be polished too much. The coarser the better.



2. Repair wear for heavy duty slurry pump

Wipe off the extruded repair agent. Remind again: when pushing the bearing, ensure that there is no lack of glue at the repair position.


3. Bearing positioning for heavy duty slurry pump
a. The simplest way is to assemble the shaft and bearing with glue, and keep it at this position until the repair agent solidifies after the accuracy is found.
b. When possible, three-point gasket positioning method or manufacturing fixture can be used for positioning and assembly. It can be put into use after complete curing.

4. Cleaning to be repaired for heavy duty slurry pump
Clean the surface to be repaired of the bearing hole with cleaning agent.

5.Paint mold dope for heavy duty slurry pump
Paint a thin layer of release agent on the outer ring of the bearing to facilitate the disassembly of the bearing in the future.

6. Antifriction repair for heavy duty slurry pump
Prepare antifriction repair agent and apply the repair agent directly to the bearing outer ring, but only to the rear half of the bearing outer ring. The coating amount shall ensure that there is no lack of glue between the bearing outer ring and the shaft hole, and the gap must be filled with repair agent.

7. Bearing installation for heavy duty slurry pump
Push the bearing coated with repair agent into the shaft hole. There are three main types: claw coupling, diaphragm coupling and hydraulic coupling.

1. Claw coupling is usually made of cast iron, which has the advantages of simple structure, convenient installation and low price. It is often used in low power (below 45KW) and less important occasions, and the intermediate elastic block (generally made of rubber) is easy to be damaged.

2. The diaphragm coupling is usually made of a group of thin metal spring sheets in various shapes, which are connected with the two half couplings on the master-slave moving shaft with bolts, also known as the metal diaphragm coupling. The utility model has the advantages of no lubrication and maintenance, high temperature resistance, good misalignment resistance, high reliability of desulfurization pump and large transmission torque.

3. Hydraulic coupling plays the role of transmitting power (torque) through the energy conversion of working fluid between pump wheel and turbine. Hydraulic coupling has the functions of overload protection and stepless speed regulation. It is generally used in large pumps with high power or working conditions that need to be changed frequently.
