Classification of electric jack

There are mechanical jacks and hydraulic jacks. The principles are different. In principle, the most basic principle based on hydraulic transmission is the Pascal principle. That is, the pressure of the liquid is the same everywhere. In this way, in a balanced system Among them, the pressure exerted on the smaller piston is smaller, and the pressure exerted on the larger piston is also larger, so that the liquid can be kept still. Therefore, through the transfer of liquid, different pressures on different ends can be obtained, so that a transformation can be achieved. The hydraulic jack that we commonly see uses this principle to achieve force transmission. The mechanical principle of the screw jack is that the handle is pulled back and forth, and the pawl is pulled to push the ratchet gap to rotate, and the small bevel gear drives the big bevel gear to rotate the lifting screw, so that the lifting sleeve can be raised or lowered to achieve the function of lifting tension . But it is not as simple as a hydraulic jack.
