QGB cylinder parsing the classification and application of cylinder

As the cylinder components in automation equipment and production lines, the popularity of the application of cylinder works by pneumatic transmission of compressed gas pressure can be converted into mechanical energy of the pneumatic actuators. There are many types of cylinder, many users tend to have the correct equipment operation caused cylinder type selection is not stable and the service life of cylinder. General press cylinder driving mode of the structure, function, classification and installation method of cylinder. According to the structure characteristics, mainly divided into piston cylinder and cylinder diaphragm type cylinder. According to the movement form is divided into linear motion of cylinder and swinging cylinder. For reciprocating linear motion can be divided into the single-acting cylinder, double acting, diaphragm type and impact cylinder. Only a single-acting cylinder cavity can input the compressed air, air supply from one side of the piston can produce pressure, only have the piston rod end, air pressure forces the pistons to generate thrust, implement a direction. The piston rod can only with the aid of outside force to back into it. Will usually with the aid of the spring force, diaphragm tension, gravity, etc. The characteristics of the single-acting cylinder is: only one inlet, simple structure, small gas consumption; With reset spring force or diaphragm force etc, part of the compressed air energy used to overcome the spring force or tension of diaphragm, and thus reduce the lose force of the piston rod; Installed in cylinder spring, diaphragm and so on, generally shorter trip; Compared with the same volume of double-acting cylinder, effective stroke. Cylinder reset spring, the tension of the diaphragm are changing with the deformation size, as a result the output force in the process of the piston rod is changing. Correct selection of the type of cylinder in practice should be according to the specific job requirements and conditions. For cylinder to travel no impact on the terminal phenomenon and impact noise should choose buffer cylinder; Buffer cylinder, often referred to as air cushion. For light weight, choose the light cylinder; Required to install a space narrow and short journeys, optional thin cylinder; With transverse load, optional with guide rod cylinder; Brake precision demanding, choose the lock cylinder. Do not allow the piston rod rotation, optional with rod rotating cylinder; Under the environment of high temperature to choose heat cylinder; A corrosive environment, need to choose the corrosion resistance of cylinder. Has the bad environment, such as dust need piston rod out of the dust cover installation. Asked to choose when no pollution to oil or no oil lubrication cylinder.
