Slurry Pump Installation

The slurry pump is a very versatile water pump. So how should the slurry pump be installed?

1. Inspection before installation

The pump must be inspected and tested before leaving the factory to ensure that it is in good working condition and installed correctly. Installation should first check whether the model and parameters of the equipment are correct, whether the parts are complete and intact, and whether the technical data and quality certificates that are carried with the machine are complete.

2. Pump installation alignment

The horizontal pump unit should be installed by the secondary grouting method. After installation, the centerline of the unit should be consistent with the centerline of the foundation. For the belt-driven pump unit, the parallelism of the pump shaft and the motor shaft should be ensured, and the belt pulley should be used for alignment. If the center distance is small, you can use a straightedge to align with the end face of the flat pulley.

3. Configuration requirements for inlet and outlet pipe sections

The suction pipe diameter should be the same as the pump inlet diameter or slightly larger than the pump inlet diameter. The principle is to avoid cavitation of the pump and prevent the slurry from depositing in the pipeline. An expansion joint should be provided between the suction port of the pump and the suction pipe to facilitate disassembly and assembly of the pump. The diameter of the outlet pipe is related to the sedimentation flow rate of the slurry properties. In general, the diameter of the discharge pipe should be equal to or slightly larger than the diameter of the pump outlet. The outlet gate valve should be the same diameter as the discharge pipe. The pressure gauge is located on the straight run between the pump outlet and the first valve.

4. Shaft seal water and cooling water requirements

High-quality lubricated brackets without cooling water. When using grease lubricating packing, do not add shaft sealing water.

The pressure of cooling water is 0.05-0.2MPa, and the flow rate is 1-3m3/h.

5. Machinery Seal

A mechanical seal is a kind of end face seal, which has the characteristics of no leakage and low power consumption.

6. Lubricant filling requirements

Rarely lubricated brackets should be added with N32 (winter) or N46 (summer) according to the oil mark position before driving. Grease lubricated brackets should be filled with lithium grease No. 2 or No. 3.

7. Slurry pump adjustment

Check and adjust the clearance between the impeller and the front fender.
