working principle

The working principle of a plunger type hydraulic pump (swash plate quantitative piston pump swash plate variable displacement piston pump swash shaft quantitative piston pump swash shaft variable displacement piston pump high pressure gear pump) is that external power drives the pump shaft to rotate (with a certain speed requirement for consistency and stability) - hydraulic pressure is generated in the pump body inner cavity - controlled by a multi way valve - to drive the actuating transmission mechanism. Its principle is mechanical energy - hydraulic energy - mechanical energy, which is mainly used to transform energy to meet the special needs of functional humanized control and working mechanisms. The working principle of a hydraulic motor is just the opposite, absorbing and converting the energy provided by the hydraulic pump into output torque and rotational speed
