1. Speed ​​regulation We already know that the axial flow pump is working at a certain speed, and access to the appropriate flow, lift, power and efficiency. When the speed changes, its performance parameters also change accordingly, so as to achieve the purpose of regulation. If the axial flow pump is powered by a diesel engine or a gasoline engine, the throttle speed can be changed by changing the throttle size. If the axial flow pump is connected with the power machine through a V-belt or flat belt indirect transmission device, the diameter of the transmission pulley can be changed to change speed Drive wheel or driven wheel can, the purpose is to change the transmission ratio. Variable speed pump performance, more economical, the scope of application is broader, all agricultural pumps can be used. 2. Variable angle adjustment From the structure point of view, axial pump impeller with a huge hub for easy installation of adjustable angle blades. When the blade installation angle is changed, the blade lift on the water also changed, thus changing the pump performance, which is the axial pump variable angle adjustment. As the blade mounting angle increases and decreases, the axial flow pump flow, lift, power that is changed, however, the highest point of efficiency but no change, it is very conducive to the axial flow pump performance regulation.
