Tips: The working principle of hydraulic jack

1. Oil pump suction process
   When the lever handle is lifted by hand, the small piston is driven upward, and the sealing working volume in the pump body increases. At this time, because the oil discharge check valve and the oil discharge valve respectively closes their respective oil paths, the working volume in the pump body increases to form a partial vacuum. Under the action of atmospheric pressure, the oil in the oil tank flows into the pump body through the oil pipe to open the oil suction check valve to complete an oil suction action.
2. 2. Vehicle lifting process
   When the lever handle is pressed down, the small piston is driven to move down, the working volume of the small oil chamber in the pump body is reduced, the oil is squeezed out, and the oil discharge check valve is opened (the oil suction check valve is automatically closed at this time The oil path leading to the oil tank), the oil enters the hydraulic cylinder (oil cavity) through the oil pipe. Since the hydraulic cylinder (oil cavity) is also a sealed working volume, the force generated by the incoming oil due to squeezing will push the big piston up and lift the car to do work. Repeatedly lifting and pressing the lever handle can make the car rise continuously to achieve the purpose of lifting.
3. 3. Vehicle falling process
   When the big piston needs to return downwards, open the drain valve (rotate 90°), then under the action of the weight of the car, the oil in the hydraulic cylinder (oil cavity) will flow back to the oil tank, and the big piston will drop to its original position.

The working principle of the hydraulic jack is: Oil is used as the working medium, the movement is transmitted through the change of the sealing volume, and the power is transmitted through the internal pressure of the oil. The hydraulic transmission device is essentially an energy conversion device.
