How are cylinders classified? What are the types of cylinders?

Cylinder There are many types, and the classification methods are also different. Generally, they can be classified according to the direction of the compressed air acting on the piston end face, structural characteristics and Classified by installation form. The specific categories are as follows:

1. Classify whether the gas pressure received by the cylinder piston is one-way or two-way:

1. Single-acting cylinder: The piston of the cylinder can only be pushed by air pressure in one direction, and requires external force in the reverse direction.

2. Double-acting cylinder: The piston of the cylinder is pushed by air pressure in both forward and reverse directions.

2. Classification based on the installation form of the cylinder:

1. Fixed cylinder: The cylinder body is fixed.​​

2. Axis pin type cylinder: The cylinder block can swing within a certain angle around the fixed axis pin.

3. Rotary cylinder: The cylinder block is usually fixed on the machine tool spindle and can rotate with the machine tool spindle. This type of cylinder is often used in pneumatic chucks on machine tools.

3. Classify the cylinders according to their functions and uses:

1. Ordinary cylinders: including single-acting and double-acting cylinders. This type of cylinder is generally used unless there are special requirements.

2. Buffer cylinder: The cylinder is equipped with a buffer device to avoid strong impact when the piston moves to the end. This type of cylinder is often used in workplaces with high pressure and high movement speed.

3. Gas-liquid damping cylinder: The air cylinder and the hydraulic cylinder are connected in series to obtain a more accurate movement speed. This type can be used in occasions with high speed regulation requirementsCylinder.

4. Swing cylinder: The action of the cylinder is reciprocating rotation around the axis, which can be used for fixture indexing, valve switching, etc.

5. Impact cylinder: It is a high-energy cylinder that uses the high-speed movement of the piston rod to form impact force. It can be used for stamping, cutting, etc.
