How Jacks Work Dec 05, 2019

Jacks are divided into two types: mechanical jacks and hydraulic jacks. The principles are different. In principle, the principle based on the hydraulic jack is Pascal's principle, that is, the pressure across the liquid is the same. In this way, in a balanced system, the pressure on the smaller piston is smaller, and the pressure on the larger piston is smaller. The applied pressure is also relatively large, which can keep the liquid still. Therefore, through the transmission of liquid, different pressures on different ends can be obtained, so that the purpose of a transformation can be achieved. The hydraulic jacks we commonly use are based on this principle to achieve force transmission. The mechanical jack adopts the mechanical principle. The handle is reciprocated. The claw pulls the ratchet gap back and forth. The small bevel gear drives the large bevel gear and rotates the weight lifting screw, so that the lifting sleeve can be raised or lowered to achieve the lifting tension. Features. But not as easy as a hydraulic jack.
