The electric hydraulic pump is a hydraulic device that converts the mechanical energy of the motor into hydraulic energy and outputs it in the form of pressure and flow. The drive shaft of the hydraulic oil pump is connected to the motor through a connector. When the motor of the hydraulic pump rotates, the drive shaft of the electric oil pump is also Synchronous rotation, and drives the cylinder to rotate together through splines.
The electric hydraulic pump is a hydraulic device that converts the mechanical energy of the motor into hydraulic energy and outputs it in the form of pressure and flow. The drive shaft of the hydraulic oil pump is connected to the motor through a connector. When the motor of the hydraulic pump rotates, the drive shaft of the electric oil pump is also Synchronous rotation, and drives the cylinder to rotate together through splines. The motor of the electric hydraulic pump has different voltages, which can be selected according to the demand.
There are also many types of motors. It is better to choose a brushless high-power motor, which not only has high power and provides sufficient power for the hydraulic pump, but also a good-quality motor can extend the service life of the hydraulic pump. Plungers are arranged along the driving axial or radial direction in the cylinder hole. The plunger of the high-pressure hydraulic pump rotates with the cylinder body. The sliding plate at the end of the plunger is always in contact with the sliding aluminum plate of Xie Pan under the action of the pressure plate. Due to the inclination angle of the swash plate, the plunger produces reciprocating motion in the cylinder hole. Every time the main pump rotates, the plunger performs a suction and discharge process, the hydraulic oil related to the volume change of the plunger and the plunger hole enters the cylinder hole under the action of suction and atmospheric pressure, and enters the hydraulic system through the valve plate under the push of the swash plate.
The volume change depends on the inclination of the swash plate. The types of electric hydraulic pumps can be divided into low-pressure hydraulic pump station, high-pressure hydraulic pump, ultra-high-pressure hydraulic pump, etc. according to the pressure. By volume: portable electric hydraulic pump and large hydraulic pump station. According to the flow: standard electric hydraulic pump and large displacement hydraulic pump. Standard functions generally have oil outlet, pressure regulating valve, reversing valve, etc. Other functions can be customized according to the needs.
