In the production process of various industries, actuators are an indispensable machine. Generally, they can be divided into two categories according to the application environment and application industry, namely, electric actuators and pneumatic actuators. The functions of these two actuators are almost the same, but they are quite different from other aspects. Here are three differences.

What are the differences between electric actuators and pneumatic actuators

1、 Structural differences

The overall structure of the pneumatic actuator is divided into two parts, namely, execution and adjustment, which are composed of three different styles and gears. The power source is gas; The electric actuator is composed of circuit control and execution, and each part can be a completely independent layer. In addition, as the name implies, the electric actuator takes electric power as its driving force.

2、 Technical differences

The obvious difference between the pneumatic actuator and the electric actuator is their technical differences. The overall structure of the pneumatic actuator is uniform, so its load capacity is good. And because it uses gas as the power source, it is particularly suitable for high torque output; The electric actuator is relatively small in size and simpler in structure than the pneumatic actuator, so from a technical point of view, it is easy to equip and flexible in power drive.

3、 Differences in use environment

The difference in operating environment is also one of the important differences between pneumatic actuators and electric actuators. This difference is also caused by the difference in structure and dynamic force between them. Generally, the operating environment of pneumatic actuators is low, even in explosive, magnetic field and gas polluted environments. However, electric actuators have requirements on the environment. No matter which one has good quality, they should strictly comply with the requirements of their use environment.

From the basic characteristics of electric actuators, it can be seen that there are big differences between electric actuators and pneumatic actuators. The three obvious differences are their structures, technical aspects, use environment, etc., but these will not affect the use, because the two actuators are used in different fields.
