How To Regulate And Control The Water Flow Of Deep Well Submersible Pumps?

For the use of high head submersible pumps, our main focus is on drainage. However, for the control of water output and flow, many people are not familiar with it. Next, we will explain various adjustment methods for the flow control of submersible pumps.
1. Variable speed adjustment. Changing the speed of a submersible pump can change its performance, thereby changing the operating point of the pump. This method is called variable speed adjustment.
2. Variable diameter adjustment. After the impeller is turned, the performance of the water pump will change according to a certain pattern, resulting in a change in the operating point of the water pump. We refer to the method of changing the operating point of the water pump by turning the impeller as variable diameter adjustment.
3. Variable angle adjustment. Changing the installation angle of the blades can change the performance of the water pump, thereby achieving the goal of changing the operating point of the submersible pump. This method of changing the operating point is called variable angle adjustment of the water pump.
4. Throttling adjustment. For the water pump device with a gate valve installed in the outlet pipeline, when the gate valve is closed, local resistance is added in the pipeline, and the characteristic curve of the pipeline becomes steeper. Its operating point moves to the upper left along the Q-H curve of the water pump. The smaller the gate valve is closed, the greater the added resistance and the smaller the flow rate. This method of changing the operating point of the water pump by closing the gate valve is called throttling regulation or variable valve regulation.
