Cylinder is an important component in mechanical equipment, used to convert pneumatic energy into mechanical motion energy. It is widely used in various fields, including industry, automotive, aerospace, etc., playing an indispensable role. The design and manufacturing of cylinders involve high-precision processes and material science, aiming to achieve stable and reliable performance.

1.       Structure and principle of cylinder

    A cylinder is usually composed of components such as cylinder barrel,  piston, seal, piston rod, etc. The cylinder barrel is the main part of the cylinder, with one end connected to the air source and the other end connected to the actuator .The piston is located inside the cylinder and is connected to the actuator through a piston rod .When airflow enters the cylinder, it pushes the piston to move. Seals are used to prevent air pressure leakage and ensure the normal operation of the cylinder.    

    When gas enters the cylinder, the pressure will push the piston forward or backward, thereby driving the actuator to complete the corresponding work. The operation of cylinders can be divided into single acting cylinders and double acting cylinders according to the gas inlet and outlet methods .one
