What is the reason for the excessive power of the sand pump shaft

The excessive shaft power of the Centrifugal Sand Pump will occur during use, which will affect the efficiency and service life of the sand pump. So what is the main reason for the excessive shaft power? In the long-term research process, we found that the following reasons will affect the shaft power of the sand pump:

1. There is friction between the impeller and the end face of the pump casing or between the impeller and the guard plate or the auxiliary impeller.

2. The pump runs at a much lower head than the design point.

3. The packing gland is pressed too tightly.

So what should we do when the shaft power is too large?

Let me briefly talk about the operation method below

1. Adjust the gap between the impeller and the end face of the pump casing and the gap between the impeller and the mechanical seal pump cover to eliminate friction.

2. Check whether the equipped working machine meets the requirements, and close the discharge valve to make the pump work at the design point.

3. Loosen the gland.

The sand pump produced by Xi'an HL has the following advantages:

1). Large flow capacity of 300 cubic meters

2). Wear-resistant and corrosion-resistant materials for flow parts

3). Mechanical seal, the service life is extended by 6 times

4). Two interfaces of metric and imperial system to meet the needs of domestic and foreign users

5). 6 series, 24 specifications, suitable for different industries
