Can adding an electric control valve behind a centrifugal pump achieve more precise flow control? Or other pumps will work too. The pump is required to have a flow rate of 1000 liters and a pressure of 0.3–0.8 MPa. It has been determined that a regulating valve cannot be installed after the pump to control the flow rate
Yes, if the control valve has good linearity, the control is very stable
Any pump will work; it’s possible to control the backflow volume
A control valve can be installed at the outlet of the centrifugal pump to regulate flow; select an appropriate flow meter, and use it as a reference for adjusting the control valve~~
When the medium is non-corrosive, piston-type electro-hydraulic valves perform better: they enable automatic control of the flow rate, velocity, and pressure of the conveyed medium, and offer functions such as constant flow, constant pressure, and elimination of water hammer.
It has been clearly stated that a control valve can be installed at the outlet of the centrifugal pump to regulate the flow rate. As for what form to adopt, it can be decided after considering various factors. If you don’t want to do it or aren’t entirely sure, consult a manufacturer, provide them with the relevant parameters, and let them help choose the appropriate option. By asking more questions, you’ll gradually understand better
Does anyone have similar process diagrams?
The ways to control flow can be backflow, variable-frequency reciprocating pumps, or adjusting the gap
