1. According to the structural characteristics: piston type, plunger type and swing type
2. According to the mode of action: single action and double action
The single-acting hydraulic cylinder can only make the piston (or plunger) move in one direction, that is, the pressure only leads to one cavity of the hydraulic cylinder, and the movement in the opposite direction must rely on external force (such as spring release or self-weight, etc.) to achieve; double-acting The movement of the hydraulic cylinder in both directions is realized by the pressure oil.
3. According to the use pressure
The hydraulic cylinder is a very important component for hydraulic machinery. It plays the role of an executive component in the entire hydraulic machinery. The hydraulic cylinder converts hydraulic energy into mechanical energy in the whole process. According to the JIB-B8354 specification, hydraulic cylinders can be divided into the following specifications according to the working pressure.
Host type
Design pressure (Mpa)
Low pressure hydraulic cylinder
0~3.5MPa
Medium and low pressure hydraulic cylinder
0~7.0MPa
Medium pressure hydraulic cylinder
7.0~14.0MPa
High pressure hydraulic cylinder
14~21.0MPa
Ultra high pressure hydraulic cylinder
Above 21MPa
