Performance regulation method of axial flow pump

Axial flow pump should be adjusted in use to make it reach the best operation state. The adjustment methods of axial flow pump can be divided into variable speed adjustment and variable angle adjustment. Next, we will introduce these two adjustment methods.

The variable-speed regulation of axial-flow pump is a more familiar regulation method. Changing the speed of its flow, head, power and efficiency will change. By adjusting the speed of its parameters to achieve the best working range. The adjustment of the speed of the axial-flow pump can be divided into two types: one is the axial-flow pump powered by diesel engine or gasoline engine, which can adjust the speed through the throttle; the other is the indirect transmission device of the triangular belt or flat belt is used to connect the axial-flow pump and the power engine. The speed can be adjusted by changing the diameter of the drive pulley.

Variable angle adjustment is not used too much, it is the same angle of adjusting blade to adjust the performance of axial-flow pump. The increase or decrease of blade angle of axial flow pump will affect the flow, head and power, and make it reach the best performance state through reasonable adjustment.

The above is the adjustment method of axial-flow pump performance, in which the variable-speed adjustment is more economical and practical, more used, and the variable angle adjustment is sometimes used.
