What’s a Pneumatic Actuator?

A pneumatic actuator uses air pressure to produce rotary or linear motion, with the piston being a crucial component. It requires mechanical parts like an air compressor and can be airtight and maintained to prevent force reduction.

A pneumatic actuator, also called a pneumatic actuator, is a device made to produce motion through air pressure. Depending on how the actuator is set up, a pneumatic actuator is capable of rotary or linear motion, and some specialty actuators can produce both. One of the most important parts of this type of actuator is the piston, which is directly responsible for the power output of the device and can reduce the amount of input air pressure required. Although this system is one of the most powerful, the horsepower will drop dramatically if there is anything blocking the air intake.

Each actuator is made to push other parts by movement and a power source is required to perform this movement. With a pneumatic actuator, air pressure is the predominant energy. This tends to be stronger than other power sources and often leads to fewer electrical parts, but this actuator needs a lot of mechanical parts. There must be parts, like an air compressor and a piston, to regulate and produce the air. Air is also cleaner than other methods, such as hydraulics, because liquids are not required for the actuator to function.

Like most actuators, a pneumatic actuator is capable of creating rotary or linear motion. Rotary pneumatic actuators are capable of creating circular and angular motions, while linear pneumatic actuators move back and forth. Some pneumatic actuators are capable of combining both types of motion, but most are one or the other.

While many parts are required to make a pneumatic actuator, perhaps one of the most important is the piston. The piston is responsible for emitting energy by first being pushed by the air pressure, which causes the piston to move downwards. As the piston moves, the input force increases and the output is generally about three times the input energy. If the piston is changed at all, it will alter the amount of pressure output from the pneumatic actuator; a larger piston results in more horsepower.

One of the major problems with using a pneumatic actuator is that the force can be drastically reduced if there are leaks or if there are problems with the air pressure entering the actuator. Any interruption in the air reduces the overall force of the actuator, so this system must be kept airtight and maintained. If particles such as dust violate the actuator, they will also reduce its effectiveness.
