QGB technology parameter of the cylinder

Pneumatic actuators is an energy conversion device, it is the pressure of compressed air can be converted into mechanical energy, the drive mechanism to realize the straight line reciprocating movement, swinging, rotary motion or impact. Pneumatic actuators divided into two major categories of gas cylinder motor. Used to provide a straight line reciprocating movement or swinging cylinder, the output force and the linear speed or oscillating angular displacement. Gas motor is used to provide continuous rotary motion, the output torque and rotational speed. Pneumatic control components used to adjust the pressure of compressed air flow and direction, etc. , to ensure that the actuator according to the procedures prescribed by the normal work. Pneumatic control components according to the function can be divided into the pressure control valve, flow control valves and direction control valves. The output of the power cylinder, QGB cylinder theory calculation in the design of output force and the hydraulic cylinder, can see the calculation in the design of the hydraulic cylinder; The load rate of beta, QGB cylinder from the research on the working characteristic of the cylinder, it is difficult to accurately determine the actual output of the power cylinder. So in the research performance and the output of the cylinder, cylinder is commonly used to the concept of load factor; Gas consumption, QGB cylinder gas consumption of cylinder is a piston moving volume per minute, according to the volume of compressed air and gas consumption in general, cylinder gas consumption refers to the free air gas consumption. , QGB cylinder of the cylinder is divided into static characteristic and dynamic characteristic. Static characteristics of cylinder, it refers to the output of the cylinder force and the minimum working pressure is closely related to the gas consumption, the highest working pressure and frictional resistance parameters. Dynamic characteristic of the cylinder is refers to the cylinder in the process of pneumatic cylinder motion two cavity pressure, air temperature, piston velocity, displacement and other parameters with the change of time. It can truly reflect the cylinder's working performance. QGB cylinder diameter should be design calculation based on load size, speed, and system pressure of work. First of all, according to actual working condition, cylinder installation and driven load analysis to calculate the actual load cylinder axial F, then selected by average speed of cylinder to cylinder load rate, preliminary selected cylinder pressure ( As a general rule, be. MPa～. MPa） , the F/L, calculate the output Ft cylinder theory and finally calculate the diameter and stem diameter, and according to the actual required roundness with standard cylinder diameter and stem diameter.
