Flow rate issues with high-pressure plunger water pumps
Thread Content
The rated flow rate of this three-plunger water pump is 30 liters per minute. If the flow rate is restricted at the outlet, only 21 liters can be discharged per minute. I would like to know what impact this has on the pump
How should we understand \"no\"? Please specify. Thank you
The outlet can’t be restricted, right? It should be possible to adjust the stroke of the injection pump.
Plunger pumps cannot adjust flow rate based on the resistance in the outlet pipeline; generally, flow rate is controlled through methods such as frequency variation, stroke adjustment, and bypass regulation
I agree with what was said above: if you restrict the outlet flow for an extended period, it will damage the pump; it’s better to reduce the stroke, lower the frequency, or use a return line for adjustment
Does bypass regulation refer to something similar to a return valve?
Does a return line refer to the mechanism that sends excess water back to the inlet?
I’m not sure what kind of setting you mean by the return valve Bypass regulation involves connecting a low-flow pipeline from the pump outlet to the pump inlet or to a tank upstream of the pump inlet; a control valve or flow-limiting orifice is installed on this bypass line.
Thank you. It's easier to understand when you put it that way.
