How to increase the switching speed of pneumatic actuators? Wuxi Xinming automatic control valve industry Co., Ltd. will give you a detailed explanation Pneumatic actuator is a kind of pneumatic actuator that makes continuous rotary motion. It is an energy conversion device that converts the pressure energy of compressed air into reverse mechanical energy. Its effect is equivalent to an electric motor or hydraulic motor. It outputs torque and drives execution. The organization makes a rotary motion. Gear type pneumatic motor, vane type and piston type are widely used in pneumatic transmission. Pneumatic actuator is a prime mover with compressed air as the working medium. It uses the expansion of compressed gas to convert pressure energy into mechanical energy. It is also commonly called a pneumatic motor. Although various types of pneumatic actuators have different structures and working principles, 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 speed of the motor can be adjusted to achieve the purpose of adjusting the speed and power. It can turn forward or reverse. Most pneumatic actuators can realize the forward and reverse of the output shaft of the gas motor, and can be reversed instantaneously. In the forward and reverse conversion, the impact is very small. There is a regulating valve on the pneumatic actuator. You can see if it has been opened to the maximum. If so, you can also consider adding signal air source pressure or pipe diameter within a certain range. Also increase the air source pressure and the size of the air source pipe, increase the corresponding cylinder hole, and then add a quick exhaust valve, which will increase his opening speed. In fact, when selecting pneumatic actuators for valves, the switching time requirements of valves should be considered. Pay attention to the air opening and closing torque and pressure opening and closing torque of valves. Under the premise of considering the safety factor of torque, consider the air intake and exhaust speed of pneumatic actuators, and consider increasing the pipe diameter and matching of pneumatic control valves and quick discharge valves on exhaust pipes and pneumatic accessories! Pneumatic actuators are sometimes equipped with corresponding auxiliary equipment. Commonly used valve positioner and handwheel organization. The effect of the valve positioner is to use the feedback principle to improve the performance of the actuator, so that the actuator can be controlled by the controller signal to achieve accurate positioning. The effect of the handwheel organization is that when the control system is due to power failure, gas failure, no output of the controller or failure of the execution organization, it can be used to directly operate the control valve to maintain the normal production. The above is about how to increase the switching speed of pneumatic actuators. Assuming you have a demand for our products, please contact online customer service for specific inquiries, quotations and other information. You are also welcome to come to our company for inquiries and are sincerely invited to cooperate with you!
