When designing a hydraulic cylinder, it is necessary to know its use, as well as the working pressure and rated working pressure of the hydraulic system, the form determines the force and effect, and finally determines the cylinder bore and stroke of the hydraulic cylinder, connection method, installation size, etc. Hydraulic system, generally There are five levels of pressure, low pressure, medium pressure, high pressure, and ultra-high pressure. A pneumatic actuator that converts the pressure energy of compressed gas into mechanical energy in the pneumatic transmission of the cylinder. There are two types of cylinders: reciprocating linear motion and reciprocating swing. Cylinders for reciprocating linear motion can be divided into four types: single-acting cylinders, double-acting cylinders, diaphragm cylinders and impact cylinders. After determining the hydraulic system, the output force of the hydraulic cylinder can be determined, etc.
In the main components of the hydraulic cylinder, including cylinder (compressed air), piston, piston rod and guide sleeve, and other cylinder materials, usually require sufficient strength and impact toughness, if the temperature is minus 50 degrees, it must be tempered . The cylinder guides the piston to perform linear reciprocating motion in the cylinder. Air in the engine cylinder converts thermal energy into mechanical energy through expansion; gas is compressed by the piston in the compressor cylinder to increase the pressure. And the inner surface of the cylinder, and has the right to the level of tolerance and surface roughness and geometric tolerance grade, etc., to ensure that the hydraulic cylinder has good sealing and movement stability (explain: stable and stable; no variability and wear resistance .
For the connection of the piston rod head, it should be selected according to the load situation. The cylinder guides the piston to perform linear reciprocating motion in the cylinder. Air in the engine cylinder converts thermal energy into mechanical energy through expansion; gas is compressed by the piston in the compressor cylinder to increase the pressure. Generally speaking, there are mainly threaded type, single earring type and three pairs of earrings. The cooperation between the piston rod and the guide sleeve should not be too tight or too loose, otherwise it is easy to have stuck phenomenon or unevenness.
