Hi guys in this article we learn the topic Pneumatic Actuator its Advantages, Disadvantages and Applications so let's see further information,  

Pneumatic Actuator its Advantages, Disadvantages and Applications

Pneumatic Actuator its Advantages, Disadvantages and Applications

Pneumatic actuator

Pneumatic actuator is a device that converts compressed energy in to mechanical movement. Principals of this actuator same of hydrolic actuator. Working fluid is compressed air. Air pressure varies from 6 to 10 Mpa. because  air pressure of components are low. The pneumatic cylinders are used to actuate the linear joints. 

Advantages 

1) In this actuators less operating parts so it is reliable.

2) Maintenance cost is less.

3) This actuators are inexpensive of all actuators. Parts of this actuators are easily available.

4) The compressed air is clean explosion proof and temperature is also low.

5) Response time is also quick, so it allow fast working cycle.

6) Compressed air easily stored and  transport long distances.

7) Control of pneumatic actuator is very simple.

8) Not requiring mechanical transmission element.

9) No electrical control is required.

10) Less leakage.

Disadvantages

1) Pneumatic actuator are not suitable for carrying heavy loads.

2) If moisture is comes in contact with units, it damage to metal components.

3) If requiring speed and control you might have add more complex electromechanical devices.

4) Performance speed is low.

5) In this actuator low power to weight ratio.

Applications

• Used in griper of robots.
• This actuator has vast application in explosion areas. 
• Piston and ignition chamber.

So in this article we discussed about the topic Pneumatic Actuator its Advantages, Disadvantages and Applications hope you understand well.
