What Factors Affect The Head of The Slurry Pump?

Slurry pumps can be widely used in electric power, metallurgy, mining, coal, building materials, the chemical industry, and other industrial departments that contain corrosive or corrosive slurry, especially suitable for power plant ash transmission. It is the ideal pump for ash removal slag. It can be used in series in the range of allowable working pressure, and the allowable working pressure is 3.6mpa. The overcurrent parts are interchangeable. The transmission part adopts the horizontal open type thin oil lubrication bracket and has two groups of water cooling systems inside and outside.

Factors affecting the head of the slurry pump

1. Relationship between pump and blade outlet placement Angle β2a

When other values are constant, the larger the blade outlet Angle, the higher the head increases with the increase of the flow rate. With the increase of flow rate, the head of sand and stone slurry pump decreases correspondingly with the decrease of blade outlet placement angle.

2. Relationship between pump and number of blades

When other values are fixed, without considering the flow loss, the more the number of blades, the greater the head. This is because the finite blade impeller can give less energy to the liquid than the infinite blade impeller.

3. Relationship between pump and speed

The higher the rotational speed, the greater the theoretical head.

4. Relationship between line loss and head

When the type of slurry pump is determined, the total head is certain. The loss of head mainly comes from the pipeline resistance, the smaller the pipe diameter, the higher the resistance, so the greater the loss of head. Therefore, after reducing the pipe diameter, the actual head of the slurry pump can not be increased, but will be reduced, leading to a decrease in the efficiency of the slurry pump. When the small diameter slurry pump is pumped with a large water pipe, the actual head of the sand and stone slurry pump will not be reduced, but the loss head will be reduced because of the reduced resistance of the pipeline so that the actual head is increased.
