Today, wuxi xinming automatic control valve industry co., ltd. will give you a specific introduction about the differences between electric actuators and pneumatic actuators?: Actuators generally include pneumatic actuators, electric actuators, hydraulic actuators of these three. The general definition of the actuator is: a driving device that can provide linear or rotary motion, use driving energy and under the action of control signals to actively operate some equipment and devices, control their switches and adjustments, and replace manual operations. Electric actuators are controlled through various types of current to know its work, while pneumatic actuators use air pressure to control its work. The functions of these two actuators are similar, but they are quite different from other aspects: ① Electric actuator: The driving source is the power source. Pneumatic actuator: the driving source is the gas source, the need for special supporting gas source station, laying pipelines, construction is more cumbersome, increase the budget. The air source is generally compressed air, so it is also equipped with a large air compressor. The power supply is very simple to obtain for all types of industrial sites. Some small equipment supporting actuators, electric plan will be more convenient (generally small equipment is not compressed gas, such as: pressing machine, shield machine, etc.) It's a bible. Energy saving Electric actuator: only when the opening of the control valve is changed, the motor is driven on demand, and the motor is powered off when the required opening is reached. The standby condition requires only a small amount of power to maintain the operation of the control unit. ② Pneumatic actuator: A certain amount of air pressure is required during the operation and standby conditions of the entire control valve. When the air pressure drops, the compressor will operate to pressurize. Generally speaking, the electric actuator is more energy-saving than the pneumatic actuator. Come on. Come on. Come on.

Differences at the skill level The obvious difference between pneumatic actuators and electric actuators is the difference in their skill level. The overall structure of pneumatic actuators is unified, so their load can be better, and because they use gas as the power source, they are especially suitable for high torque output. However, the volume of electric actuators is relatively fine and simpler than that of pneumatic actuators. Therefore, from the perspective of skills, they are simply equipped, the power drive is also very sensitive. Come on. Come on. Come on. Come on. Come on. Come on. Come on. Come on. Come on. Come on.

Differences in the use of the environment The difference in the use 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 energy and power between them. In general, the use environment of pneumatic actuators requires lower requirements, even in explosive, magnetic field and gas polluted environments. However, electric actuators have requirements for the environment. No matter which quality of electric actuators is good, they must strictly abide by the environmental requirements of their application. From the fundamental characteristics of electric actuators, we can know that there is a big difference between electric actuators and pneumatic actuators. The three obvious differences are their structure, skill level, application environment and so on, but these will not affect the application, because the two actuators are used in different fields. Summary: Electric actuator will have more advantages in selection. It is compact in structure and compact in size. Compared with pneumatic actuator, electric actuator has relatively simple structure, convenient access to energy, no danger of "air leakage" and high reliability. The performance of the electric valve is higher than that of the pneumatic valve, and its torque will be greater.
