For the use of submersible pumps, we mainly drain water, so I believe many of them do not understand the control of water output and water flow. Next, I will explain the various adjustment methods of water flow control of submersible pumps.
1. Variable speed adjustment. Changing the speed of the submersible pump can change the performance of the pump, thereby changing the working point of the pump. This method is called variable speed adjustment.

2. Variable diameter adjustment. After the impeller is turned, the performance of the pump will change according to a certain law, so that the working point of the pump will change. We call the method of turning the impeller to change the working point of the water pump as variable diameter adjustment.
3. Variable angle adjustment. Changing the installation angle of the blades can change the performance of the pump, so as to achieve the purpose of changing the working point of the submersible pump. This way of changing the working point is called the variable angle adjustment of the water pump.
4. Throttle adjustment. For the pump device with the gate valve installed in the outlet pipeline, if the gate valve is closed for a small time, the local resistance is increased in the pipeline, the pipeline characteristic curve becomes steeper, and the operating point moves to the upper left along the Q-H curve of the pump.
