The principle of hydraulic jack cylinder.

The principle of Hydraulic Jack Cylinder, when the external wrench is lifted upward, it will drive the small piston to move upward, and the oil in the oil tank is sucked into the lower part of the small piston through the oil pipe and one-way valve.
When the external wrench downward reality, the small fire plug downward movement, the pipeline to the oil tank is blocked by the one-way valve, hydraulic oil through the internal oil circuit and one-way valve is pressed into the lower part of the large piston, so repeatedly lift and press down, and constantly press the oil into the lower part of the large piston, so that the piston upward movement, so as to jack up the weight.
When the need to put down, you need to open the return valve, the hydraulic oil under the large piston will flow back to the reservoir, the piston and the weight will fall down together.

According to Pascal's principle, the area ratio of the piston and the pressure ratio are the same, that is, the larger the area, the higher the pressure. Therefore, the pressure at the small piston is transferred to the large fire plug under the time is multiplied. Therefore, we can easily lift heavy objects by jacking.

Deeleap factory is mainly producing all kinds of high pressure hydraulic pumps and cylinders.
