A power hydraulic actuator is a hydraulic drive unit integrating a motor, centrifugal pump, and cylinder, mainly used for braking control of mechanical equipment and operation of industrial valves, gates, and other mechanisms. The equipment is produced by multiple enterprises in Jiaozuo City (such as Jianghe Brakes, Gongli Brakes, etc.), covering series models like Ed, YT1, BED, and is widely used in the fields of lifting transportation, metallurgy, mining, and port machinery.

Compared to traditional mechanical drives, its features include:

High-Efficiency Energy Conversion: The efficiency of electrical to hydraulic energy conversion can reach over 90% (refer to "Hydraulic and Pneumatic Technology Handbook"), significantly higher than the 70%-80% of mechanical transmission.

2. Precise Control: Achieving millimeter-level displacement accuracy through adjusting current or oil pressure, suitable for applications such as precise assembly and machine tool positioning.

3. Modular Design: High integration, with a volume reduced by approximately 30% compared to traditional hydraulic systems, making installation and maintenance easier.
