The Pneumatic Motor of Electro Pneumatic Positioner

The pneumatic motor of the electro pneumatic positioner can be steplessly adjusted. As long as the opening of the intake valve or exhaust valve is controlled, that is, the flow of compressed air is controlled, the output power and speed of the motor can be adjusted. The purpose of adjusting speed and power can be achieved. It can be rotated forward and reversed. Most air motors simply use the control valve to change the direction of the motor's intake and exhaust, which can realize the forward and reverse rotation of the output shaft of the air motor, and can change the direction instantaneously. In the forward and reverse conversion, the impact is small. One of the main advantages of the air motor reversing operation is that it has the ability to rise to full speed almost instantaneously. The vane-type air motor can rise to full speed in one and a half revolutions; the piston-type air motor can rise to full speed in less than one second. Using the control valve to change the direction of the air intake can realize forward and reverse rotation. The time to realize forward and reverse rotation is short, the speed is fast, the impact is small, and there is no need to unload the load.
