DIFFERENCE BETWEEN ELECTRIC AND PNEUMATIC ACTUATOR

Source:新捕京3522com原创 Author:master UpdateTime:2014-4-29 9:07:32 Hits:4113

Electric as well as pneumatic actuators are quite well known for their varied uses. Both have their own merits and are useful in different situations. An electric actuator makes use of electrical energy to produce mechanical energy while a pneumatic actuator is an air-operated actuator that converts air pressure into mechanical force to operate the valve.

Pneumatic actuators offer more force and speed per unit size than the electric actuators. One can easily adjust the force and speed on the pneumatic actuators. Thus, pneumatic actuators are better to control and regulate the force and speed in the system.

The component costs of pneumatic actuators are lower than the electric actuators, which come with a hefty component costs. However, their maintenance and operating costs are quite high as compared to the electric actuators. The design of the pneumatic actuators resists overheating. In contrast, the electric actuators can tend to overheat. Also, while the pneumatic actuators are insensitive to wet environment or moisture, the electric actuators need to keep well away from moisture.

The pneumatic actuators can be stalled easily but the electric ones cannot be stalled during their operation or use. The pneumatic actuators have a high torque to weight ratio as compared to the electric actuators.
