What is the Reason for the Power Loss in the Slurry Pump?

When the liquid delivered by the slurry pump flows in the pump, there are usually three types of hydraulic loss, volume loss and mechanical loss. As a Slurry Pumps Manufacturer, share with you.

Hydraulic loss of slurry pump

When the liquid flows in the pump, because the smoothness of the flow channel is different, the resistance is also different. In addition, when the fluid enters and exits the impeller, collisions and vortices will occur, as well as energy loss. These two losses are collectively referred to as hydraulic loss.

Volume loss of slurry pump

Because the pump body is stationary, there is a gap when the impeller rotates in the pump body. In this way, a small part of the high-pressure liquid at the outlet of the impeller will automatically flow back to the inlet of the impeller, or a part of the liquid may flow back to the inlet of the impeller from the balance pipe.

Or leakage from the seal, these losses are collectively referred to as volume loss.

Mechanical loss of slurry pump

Because the pump has friction with bearings, packing, etc. during operation, the impeller runs in the pump body, and its front and rear cover plates also have friction with the liquid.

The energy loss caused by these frictions is collectively referred to as mechanical loss, which is the internal power loss of the slurry pump.

So how to improve the efficiency of the slurry pump?

In order to reduce the hydraulic loss, volume loss and mechanical loss of the pump.

When the pump is running, it should work within the scope of use as much as possible.

Due to wear and tear, the gap will increase, which will increase leakage and reduce pump efficiency.

Therefore, the pump should be repaired in time to maintain a good lubrication state.

The tightness of the packing gland and other fasteners should be appropriate to reduce energy consumption and improve the efficiency of the pump. Our company also has HH Slurry Pump on sale, welcome to contact us.
