Pneumatic actuator is an actuating device that opens, closes or regulates a valve with gas pressure, also known as pneumatic device. In this article, DELCO Valve will share the working principle, main applications, advantages and disadvantages of pneumatic actuators.
Working Principle of Pneumatic Actuator
The working principle of pneumatic actuator is to use gas as power to realize mechanical movement. There will be a cylinder inside the pneumatic actuator, which is equipped with a piston. When the gas passes through the cylinder, the piston will move according to the flow direction of the gas. The movement direction and speed of the pneumatic actuator can be controlled by a control valve, which can change the flow direction and flow rate of the gas according to the different control signals, thus realizing different movement methods.
Pneumatic Actuator Applications
- Pneumatic actuators are used for fluid control in petroleum and chemical, metallurgy and power, water treatment and other industries.
- Pneumatic actuators are used in packaging and printing, machining and electrical and electronic applications to ensure product quality and stability.
- Pneumatic actuators are used in the medical equipment field to control the moving parts of various surgical instruments and equipment to ensure the accuracy and safety of the surgical process.
- Pneumatic actuators are used in the food processing field to control the moving parts of packaging machines, filling machines and other equipment to ensure the sealing and sanitation of food packaging.
- Pneumatic actuators aerospace field to ensure the normal operation and safety of aircraft; in the field of transportation: used to control ships, aircraft and other mechanical devices.
Pneumatic Actuator Advantages
- Easy to control: pneumatic actuator can control its movement by controlling the air pressure, this kind of control is simple, easy to understand and easy to realize.
- High precision: Pneumatic actuators have fast response speed and can accomplish precise movement in a very short time.
- Easy maintenance: pneumatic actuators are simple in design, easy to maintain, and have a long life because they do not require lubrication.
- Wide range of application: Pneumatic actuators can be used in a variety of different types of mechanical devices, so it has a very wide range of application.
- Compact size: Pneumatic actuators are compact and small in size and can be used in applications where space is limited.
- High Reliability: Pneumatic actuators are highly reliable due to their simple design, easy maintenance and no lubrication is required.
Pneumatic Actuators Disadvantages
- Pneumatic actuators typically do not work in high-speed or high-precision applications.
- Pneumatic actuators can be affected by temperature changes, which can lead to poor performance.
- Pneumatic actuators typically require a large amount of air pressure to operate, which means they may require additional air compression equipment.
- Pneumatic actuators may generate a lot of noise, which can be a problem in the work environment.
- Pneumatic actuators may require regular maintenance and replacement parts, which can increase their operating costs.
