Introduction to Hydraulic Pump

2021-11-05
Hydraulic Pump is the power component of the hydraulic system. It is driven by the engine or electric motor, sucks oil from the hydraulic tank, forms pressure oil and discharges it, and sends it to the actuator. Hydraulic Pump is divided into gear pump, plunger pump, vane pump and screw pump according to the structure.

A hydraulic component that provides pressurized liquid for hydraulic transmission is a kind of pump. The function of Hydraulic Pump is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into pressure energy of liquids. There are many factors that affect the service life of Hydraulic Pump. In addition to the pump's own design and manufacturing factors, it is also related to the selection of some components related to the use of the pump (such as couplings, oil filters, etc.), and the operation during trial operation.
The working principle of a hydraulic pump is that movement brings about a change in the volume of the pump cavity, thereby compressing the fluid to make the fluid have pressure energy.
The necessary condition is that the pump cavity has a sealed volume change.
