Small hydraulic power unit

Hydraulic power unit A small hydraulic power unit is a device that uses hydraulic energy transmission and control, usually consisting of hydraulic pumps, hydraulic motors and hydraulic cylinders. It has the advantages of small size, light weight, high power and high transmission efficiency, and is widely used in construction machinery, agricultural machinery, aerospace, automobiles and other fields. The working principle of the small hydraulic power unit is to convert liquid pressure into mechanical energy through a hydraulic pump, and then convert the mechanical energy into liquid pressure through a hydraulic motor or hydraulic cylinder. The hydraulic pump is powered by a driving device (such as a motor), sucks liquid from a low-pressure area, and then sends it to a hydraulic motor or hydraulic cylinder through a pressure oil pipe to generate a corresponding power output. The application range of small hydraulic power devices is very wide. For example, in construction machinery…
