8T Car Single pump Long Ram Hydraulic Jack has a shell, large piston, small piston, wrench, oil tank and other components. 8T Car Single pump Long Ram Hydraulic Jack’s working principle is that the wrench goes up to drive the small piston up, the oil in the tank is sucked into the lower part of the small piston through the tubing and one-way valve, the wrench presses down to drive the small piston down, the lower oil circuit of the tank and the small piston is blocked by the one-way valve, the lower oil of the small piston is pressed into the lower part of the large piston through the internal oil circuit and one-way valve, because the lower pressure of the small piston increases tens of times, The area of the large piston is dozens of times that of the small piston. The oil pressure produced by hand is squeezed into the large piston. It is known from PASCAL’s principle that the area ratio of the large piston is the same as the pressure ratio. When 8T Car Single pump Long Ram Hydraulic Jack is finished, a valve that is normally closed is opened manually, and the fuel is forced back into the tank by the weight of the car.
