Pneumatic actuators do to speed things up?

Pneumatic actuator is a kind of continuous rotation movement of the pneumatic actuators, is a kind of pressure of the compressed air can be converted into the energy of the rotary mechanical energy conversion device, its function is equal to the motor or hydraulic motor, its output torque, drive actuators for rotary motion. Widely used in pneumatic transmission is vane, piston and gear type pneumatic motor. Pneumatic actuators is compressed air as working medium of the prime mover, it is to use compressed gas expansion effect, the pressure can be converted into mechanical energy power plant, usually also called pneumatic motor. Various types of pneumatic actuators in spite of different structures, working principle and there's a difference, but most of the pneumatic equipment has the following features: can be stepless speed regulation. As long as the inlet valve control or exhaust valve opening, which control the flow of compressed air, can adjust the output power and speed of the motor, in order to achieve the purpose of adjusting the rotational speed and power. To be able to forward can reverse. Most of the pneumatic control valve actuator simply used to change the direction of the motor inlet and exhaust, air motor output shaft can be realized forward and inversion, and can be instantaneous commutation. In forward and reverse transformation, the impact is very small. Pneumatic actuators on a regulator, you and see if it is already open to the largest, if it is, in a certain range increases air pressure or pipe diameter can also be considered. And increase the air pressure and air pipe size, the corresponding cylinder hole will increase, and then speed up the discharge valve, this will improve his opening speed. Actually when valves are equipped with pneumatic actuators should consider the time requirements of valve, pay attention to the air valve open and close of under pressure open-close torque, torque and on the premise of considering the safety of the torque coefficient, considering the pneumatic actuator of intake and exhaust speed, on the exhaust pipe and pneumatic accessories of adding pipe diameter and the selection of the control valve and quick discharge valve.
