Working Principles of Hydraulic Pump (With Videos)
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 Braking System: Diagram, Parts & Working [PDF]
A hydraulic system uses liquid under pressure to transfer force, move an object, or increase its force. The fluid pressure is known as hydraulic pressure. Brakes that are operated using hydraulic pressure are called hydraulic brakes. This type of braking system transfers pressure from the controlling mechanism to the braking mechanism …
