the Uses of Slurry Pumps

As a Centrifugal Water Pump Manufacturer, share with you. Slurry pumps are often used in coal mines, electric power, and seawater sand selection industries. They are widely used in these industries. Let's understand them together.

Slurry pumps are in the power industry, mainly thermal power plants. In thermal power plants, because a large amount of coal is used for power generation, the slag or ash after coal combustion needs to be removed. The slurry pump is used to remove the ash and slag. After mixing a certain amount of water, the slag is removed by the slurry pump. It is transported to the place where the slag is piled, so sometimes the slurry pump also becomes the ash pump in the power plant.

In the coal washing industry, due to different working conditions, larger coal lump and coal gangue are easy to block, which requires high design requirements for slurry pumps.

In the field of seawater sand selection, the application of slurry pumps has gradually been recognized by customers. However, when selecting sand in seawater and digging sand in rivers, slurry pumps are more easily called sand pumps or dredging pumps. Although the names are different, in terms of structural features and pump performance principles, they can all be called slurry pumps. Therefore, in this seawater sand selection, we often call it a sand pump, and it is customarily called a dredging pump in river dredging.

To keep the slurry pump in good working condition, the pump needs to be installed correctly.

Horizontal slurry pump units, such as wear-resistant slurry pumps, should be installed using the secondary grouting method. According to the installation dimensions of the pump and motor, the pump should be installed directly on the foundation. After installation, the centerline of the unit should be consistent with the centerline of the foundation; the deviation of the center elevation of the unit from the design value should not be greater than ±2 mm, and the allowable horizontal error of the unit is 1/10 000.

For slurry pump units that use couplings for direct drive, the coaxiality of the units are generally ensured by the alignment coupling. The alignment method of the coupling is: use a straightedge (knife-edge ruler and feeler gauge are parallel to the axis line, use the knife-edge ruler to align the outer circle of the coupling, check the four positions that are 90° each other, and the maximum error should be Not more than 0.1 mm; it is also possible to use a magnetic dial indicator with a feeler gauge alignment coupling, fix the magnetic dial indicator on the outer circle of one side of the coupling and crank, and place the magnetic dial indicator probe on On the outer circle of the opposite coupling, the runout of the dial indicator should not be greater than 0.1 5 mm. A uniform axial gap should be maintained between the two couplings. The gap of the coupling should be measured with a feeler gauge, and the gap should not be greater than 0.1 mm.

For the slurry pump unit driven by a pulley, the parallelism between the pump shaft and the motor shaft should be maintained, and the pulley is usually used for alignment. Slurry pump units with a small pulley center distance can be aligned with a straightedge against the end surface of the flat pulley; for slurry pump units with a large pulley center distance, you can use a cable to locate the end surface of the flat pulley.
