For the use of FY Immersible Pump, we mainly transport corrosive media containing a small amount of solid particles and abrasive materials. As for flow control, I believe that many people do not understand it. Next, we will focus on the flow control of FY Immersible Pump. Explain this kind of adjustment method.
1. Variable speed adjustment. Changing the speed of the FY Immersible Pump can change the performance of the pump, thereby changing the working point of the pump. This method is called variable speed adjustment.
2. Adjustable diameter adjustment. After the impeller is turned, the performance of the FY Immersible Pump will change according to a certain rule, which will change the operating point of the pump. We call the method of turning the impeller to change the working condition point of the pump, which is called the variable diameter adjustment.
3. Variable angle adjustment. Changing the installation angle of the blade can change the performance of the FY Immersible Pump, so as to achieve the purpose of changing the operating point of the FY Immersible Pump. This way of changing the operating point is called variable angle adjustment of the pump.
4. Throttle adjustment. For the FY Immersible Pump device with gate valve installed in the outlet pipeline, if the gate valve is closed for a small amount of time, local resistance is increased in the pipeline, and the pipeline characteristic curve becomes steep, and its operating point is along the QH curve of the pump to the upper left move. The smaller the gate valve is closed, the greater the increased resistance and the smaller the flow rate. This method of changing the operating point of the pump by closing the gate valve is called throttling adjustment or variable valve adjustment.
