In the pneumatic actuator, there are many kinds of actuator, such as scotch yoke pneumatic actuator, electric actuator, piston actuator and so on. Because the principle of each actuator is different, its scope of application is also different. Among them, the scotch yoke pneumatic actuator and the electric actuator are often used to compare, so what is the difference between them? Now let's get to know it.

Electric actuator is also called electric actuator. According to the movement mode, it can be divided into angular stroke and straight stroke; it is often used to match various valves to form electric valves or electric regulating valves; AC AC or DC direct current is used as driving energy; according to the movement mode, it can be divided into two categories; its advantages are easy access to energy, fast signal transmission speed, long transmission distance, easy centralized control, high sensitivity and precision, and it can cooperate with electric regulating instruments. Easy to install and connect. The disadvantage is that the structure is complex, the thrust is small, the average failure rate is higher than that of the pneumatic actuator, which is suitable for places where the explosion-proof requirements are not high and the gas source is scarce.

Pneumatic actuator
As we all know, pneumatic actuators are a kind of classifications of actuators. In the last few articles, the small edition has explained the relevant contents of pneumatic actuators for you. I believe that you have a general understanding of pneumatic actuators, but today we will go further into pneumatic actuators. Here we will explain the difference between pneumatic actuators and electric actuators. Rong.
The actuating mechanism and regulating mechanism of pneumatic actuator are unified as a whole. The actuating mechanism of pneumatic actuator includes film type, piston type, fork type and gear rack type. The piston stroke is long and suitable for situations requiring greater thrust, while the membrane stroke is small and can only drive the valve stem directly. Pneumatic fork actuator has the characteristics of large torque, small space, torque curve more in line with the torque curve of the valve, but it is not very beautiful; it is commonly used in large torque valves. The rack-and-pinion pneumatic actuator has the advantages of simple structure, stable and reliable operation, and safety and explosion-proof. It is widely used in power plants, chemical industry, oil refining and other production processes with high safety requirements.
