How can the pneumatic actuator speed up?
Pneumatic actuator is a continuous rotating pneumatic actuator, is an energy conversion device, the pressure energy of compressed air into rotating mechanical energy, equivalent to the motor or hydraulic motor, output torque, drive the actuator rotation. Vane type, piston type and gear type pneumatic motors are widely used in pneumatic transmission. Pneumatic actuator is a power device that uses compressed air as the working medium. It is a power device that uses the expansion of compressed gas to convert pressure energy into mechanical energy. It is usually called pneumatic motor.
Although the structure and working principle of various pneumatic actuators are different, most pneumatic actuators have the following characteristics:
Can be stepless speed regulation. 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 of the motor can be adjusted, so as to achieve the purpose of adjusting the speed and power.
It can turn forward or reverse. As long as most pneumatic actuators simply use control valves to change the direction of intake and exhaust of the motor, positive and negative rotation of the motor output shaft can be achieved and the direction can be changed immediately. In the positive and negative conversion, the impact is small.
There is a regulating valve on the pneumatic actuator. If so, you can also consider increasing the air source pressure or pipe diameter within a certain range. In addition, the air source pressure and the air source pipe size should be increased, the corresponding cylinder hole should be increased, and then the exhaust valve should be accelerated to improve its opening speed.
In fact, the valve selection of pneumatic actuator should consider the valve switching time requirements, pay attention to the valve switching torque and pressure switching torque, on the premise of considering torque safety factors, consider the air inlet and exhaust speed of the pneumatic actuator, in the pipeline and pneumatic accessories to consider the increase of pipe diameter and gas control valve and fast exhaust valve!
