Commonly used water pump performance adjustment method has the following several.
1. Variable speed regulation:
Change the speed of the pump, to change the performance of the pump. Under normal circumstances, to reduce the pump speed is allowed to run.
2. Reducing regulation :
The pump impeller diameter turning smaller, to change the performance of the pump, so as to achieve the purpose of expanding the scope of use of the pump.
3. Variable angle adjustment :
In order to change the performance of the pump by changing the angle of the vane of the axial flow pump, the pump can operate at high efficiency to expand its use range.
4. Water pumps in series and parallel :
Namely when a pump can not meet the actual head and flow requirements, you can pump or more than two sets of pumps in series or parallel.
1). The series operation of the pump is the pump ends of two or more than two of the same performance is that the water outlet pipe of a water pump and a water pump is connected with the tube, the aim is to increase the lift, while maintaining constant flow.
2). The parallel operation of the pump is two or more than two pumps are connected to the common outlet, its purpose is to increase the flow rate.
