Do hydraulic power station pumps run continuously?
Thread Content
Does the electric pump of a hydraulic press keep running when the press is not in use or while it is maintaining pressure? In other words, does a 1KW power pump definitely consume 1 kilowatt-hour of electricity per hour?
The electric pumps used in hydraulic presses are mostly positive-displacement types (piston-type)~~~~ Such pumps are equipped with a check valve at their outlet; as a result, under normal conditions, if the piston of the hydraulic cylinder does not move, the electric pump does not operate； For a 1kw pump station, the value indicated is the rated power~~~ During operation, the load varies~~~ As a result, the pressure at the pump outlet changes~~~ And the motor power also changes ；
