Product Introduction: A jack is a commonly used lifting tool in production.QYLType vertical hydraulic jack is a national type new series products. Its structure is simple, easy to operate, small volume, light weight, convenient for maintenance. Widely used in factories, warehouses, bridges, wharves, transportation construction engineering departments and other lifting operations. This product can only be used vertically, and its working environment temperature is -20Celsiusto+45CelsiusShould not be used in acid and alkali or corrosive gas environments.
Working Principle:
The hydraulic jack operates based on the principles of the Pascal's law. It consists of several parts including a tank, two pressure oil cylinders of different sizes, a rocking arm, and a closing needle valve. When working, the small piston sucks oil into the small pressure oil cylinder, and when pressing down on the small piston, the oil is pressed into the large pressure oil cylinder. The pressure of the oil on the small piston is transmitted to the large piston, allowing the heavy object to be lifted. The small piston continuously recursively acts, allowing the heavy object to be lifted to a certain height. After the work is completed, the closing needle valve is opened to connect the large pressure oil cylinder and the tank. At this time, as long as a slight pressure is applied to the large piston, it can fall, and the oil returns to the tank.
