How to Vary Hydraulic Pump Flow to Get the Most Out of Your Prime MoverIn order to generate massive force, you must apply pressure to a large area. The trade-off is that the larger the area that is being acted on, the more flow (volume) it takes to get an actuator to move a given distance. If you want a cylinder to generate massive force and move quickly, you will need a massive prime mover.
With today’s ever changing demands on hydraulics and the advent of new Tier 4 engine, the need to vary the input torque of hydraulic pumps becomes evident. Using the Power Shift regulator, input torque to the pump can be limited to prevent engine overload and stalling at varying engine speeds and output power. Optimizing the horsepower input demands of the pump can result in significant savings in fuel consumption and emission output.
