How To Adjust And Control The Water Flow Of Sanitary Volute Pump

For the use of Sanitary Volute Pump, we mainly drain water, so for the control of water output and water flow, I believe many people do not know how to understand it. Next, the various adjustment methods of water flow control of sanitary volute pumps are explained.

1. Variable speed adjustment. Changing the speed of the sanitary volute pump can change the performance of the sanitary volute pump, thereby changing the operating point of the sanitary volute pump. This method is called variable speed adjustment.

2. Variable diameter adjustment. After the impeller is turned, the performance of the sanitary volute pump will change according to a certain rule, thereby changing the operating point of the sanitary volute pump. We call the method of turning the impeller to change the operating point of the sanitary volute pump variable diameter adjustment.

3. Variable angle adjustment. Changing the installation angle of the blades can change the performance of the sanitary volute pump, thereby achieving the purpose of changing the operating point of the sanitary volute pump. This way of changing the operating point is called variable angle adjustment of the sanitary volute pump.

4. Throttling adjustment. For a sanitary volute pump device with a gate valve installed in the outlet pipeline, when the gate valve is closed, the local resistance in the pipeline is increased, and the pipeline characteristic curve becomes steeper, and its operating point moves to the upper left along the Q-H curve of the sanitary volute pump. The smaller the gate valve is closed, the greater the increased resistance, and the smaller the flow rate becomes. This method of changing the operating point of the sanitary volute pump by closing the gate valve is called throttling regulation or variable valve regulation.
