Description
 

Hydraulic pump is a component that provides power for hydraulic system, driven by engine or electric motor, which can convert mechanical energy into pressure energy of liquid. The working principle of the hydraulic pump is to change the volume of the pump chamber through movement, thereby compressing the fluid to make the fluid have pressure energy.

The cam of the hydraulic pump is driven to rotate by the electric motor. When the cam pushes the plunger to move upward, the sealing volume formed by the plunger and the cylinder is reduced, and the oil is squeezed out of the sealing volume and discharged to the required place through the one-way valve. When the cam rotates to the descending part of the curve, the spring forces the plunger downward to form a certain degree of vacuum, and the oil in the oil tank enters the sealing volume under the action of atmospheric pressure. The cam makes the plunger rise and fall continuously, the sealing volume decreases and increases periodically, and the pump continuously absorbs and discharges oil.
