I see that the nameplate on the high-pressure reciprocating pump indicates a rated power of 75 kW and a rated flow rate of 11,000 liters per hour. What is the current consumption, and how many cubic meters of fluid does it handle per hour?
The flow rate of a reciprocating pump depends on the plunger area, stroke length, number of strokes per minute, and the number of cylinders. Adjusting the flow rate means adjusting these parameters; changes in these parameters lead to changes in power and current, and these values need to be measured specifically.
W=UI can be used to calculate the current at a given flow rate; the rated flow rate is already specified
The current can be measured in real time; calculating it using power does not yield very accurate results. Moreover, the rated current is usually indicated on the nameplate – isn’t the rated flow rate 11,000 L/h?
Only these two can’t be calculated, right? There should also be an efficiency factor, I think
