Description

Technical Field

[0001] The utility model relates to the technical field of electric hydraulic jacks, in particular to an electric hydraulic jack. Background Art

[0002] The electric hydraulic jack is composed of a hydraulic cylinder and an electric pump station. It can realize various operations such as jacking, pushing, pulling, and squeezing. The most basic principle of hydraulic transmission is Pascal's principle, that is, the pressure of the liquid is consistent everywhere. In this way, in a balanced system, the pressure exerted on the smaller piston is relatively small, and the pressure exerted on the larger piston is also relatively large. This can keep the liquid still. Therefore, through the transmission of liquid, different pressures can be obtained at different ends, so that the purpose of transformation can be achieved. The hydraulic electric jacks we often see use this principle to achieve force transmission.
