Commissioning of axial flow pump after installation

Axial flow pumps are installed and commissioned in different situations to meet job requirements.
1, variable speed axial flow pump is to work at a certain speed, and at a certain speed to obtain the appropriate flow, head, 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 size can be changed to change the speed. If the axial flow pump is connected to the power machine by means of a V-belt or flat belt indirect drive, the drive pulley diameter can be changed to change the speed, Wheel or driven wheel can be, the purpose of foot to change the transmission ratio. Variable speed pump performance is more economical, wider scope of application, all agricultural pumps can be used.
2, variable angle adjustment From the structure point of view, axial flow impeller has a huge wheel hub, easy to install adjustable angle of the blade. When the blade installation angle changes, the blade of the lift of the water also changed, thus changing the performance of the pump, which is the axial flow pump variable angle adjustment. As the blade installation angle increases or decreases, the flow, head and power of the axial flow pump will change with the change. However, there is no change in the maximum efficiency point, which is very beneficial to the axial pump performance.
