Quick Lift Auto Maintenance Jack 3ton for Auto Repair Lifting

When the high-pressure rubber hose leaves the factory, it has passed the withstand voltage test of 1.25 times of the rated pressure. Due to the aging of colloid, users should pay attention to regular inspection, once every six months, when using it for a long time. In case of leakage, bulge or explosion during pressure test, it must be replaced. When using, avoid discounts and sharp turns, and do not get too close to the rubber hose to prevent explosion. Steel pipe can be used for fixing. All parts shall be cleaned with kerosene. Pay attention to protecting all mating surfaces of the jack, and do not bump at will. After assembly, all moving parts shall move flexibly without local jamming.

Jack is divided into mechanical jack and hydraulic jack, and the principle is different. In principle, the most basic principle that hydraulic transmission is based on is Pascal's law, that is, the pressure of liquid is consistent everywhere. In this way, in a balanced system, the pressure exerted on a smaller piston is smaller, while the pressure exerted on a larger piston is larger, so that the liquid can be kept still.
