Working Principles of Hydraulic Pump – The functioning concept of hydraulic pumps is similar to that of displacement pumps. A hydraulic pump is a key component of a hydraulic system because it converts mechanical energy from an engine or motor to hydraulic energy. To conduct beneficial work, the hydraulic pump comprises pressure and flow.
The flow of a pump is determined by its speed and displacement (volume). By rotating a pump faster, a bigger pump may transfer more fluid at once or push on more fluid. In hydraulics, power is a combination of pressure and flow. The horsepower is doubled by doubling the pressure while keeping the flow the same. On the other side, doubling the flow while maintaining the same pressure doubles the horsepower.
What is a Hydraulic Pump
The core of a hydraulic system is a hydraulic pump, which is a mechanical source of power that transfers mechanical energy into hydraulic energy (i.e. flow, pressure). In other words, it produces enough flow to counteract the pressure generated by the load at the pump output. Hydraulic power is pressure times flow, whereas mechanical rotational power is the combination of torque and speed.
When a hydraulic pump is turned on, it causes a vacuum at the pump inlet, which draws liquid from the reservoir into the pump’s intake line, where it is supplied to the pump output and pushed into the hydraulic system by mechanical action.
