Pneumatic actuators actuators classification

Pneumatic actuator
there are two main types of actuators, is a kind of double-acting actuators, the other is a single acting actuator. The selection of actuators with double acting mainly DA series pneumatic actuators as the main example. Article gear actuator output torque is the product of piston pressure with the pitch circle radius. Double-acting actuators of frictional resistance is small and the efficiency is relatively high. Rotate clockwise or counterclockwise to rotate in the output torque is linear. Single-acting actuator pneumatic actuator selection is the SR series pneumatic actuators, the output torque is in the process of the two different operation, according to the position of the stroke, each operation can produce two different torque values. Actuator is in both cases on the basis of a balance torque to carry on the design. But whatever the type of actuator, it on the pneumatic actuators are able to play a more important role.
