What are the types of actuators for 3C fire dampers?

There are three types of actuators for 3C fire dampers, which are pneumatic, electric, and hydraulic actuators. Now let's introduce the advantages and disadvantages of these three types of actuators

The characteristic of large pneumatic actuators is high safety. Among the three types of actuators, pneumatic actuators have the advantages of fire prevention and explosion prevention, and are suitable for applications in industries such as petrochemicals, petroleum, and oil processing. In addition to its explosion-proof performance, the advantages of pneumatic actuators also lie in their good cost-effectiveness, simple and convenient use, easy maintenance, and relatively low technical requirements for personnel. The disadvantage of pneumatic actuators is their low control accuracy, which cannot be compared with electric and hydraulic actuators. This is due to the compressed gas driving method of pneumatic actuators. The compressibility of gas makes pneumatic actuators lack sufficient anti offset performance, thus lacking competitiveness in control accuracyThe usage rate of electric actuators has been increasing in recent years, especially in high-pressure water systems, where electric actuators exhibit advantages that the other two types of actuators do not possess. Electric actuators have high output thrust and stability, but at the same time, their cost is lower than that of hydraulic actuators, making them a cost-effective choice. The parameter control of electric actuators is very detailed, but their structure is complex and the failure rate is higher than that of pneumatic actuators. It requires dedicated personnel with high technical level to operate and maintain them. The electric actuator receives electrical signals, which can easily cause ignition problems, and its safety is inferior to the other two types of actuatorsHydraulic actuators have many performance advantages, such as high output thrust, good resistance to offset, suitable control, response speed, and stable operation. Hydraulic actuators are driven by liquids, which have incompressible properties, giving them excellent resistance to displacement and stable adjustment. The disadvantage of hydraulic actuators is their high cost. To operate hydraulic actuators, hydraulic stations and oil pipelines need to be equipped, which requires a significant initial investment. The volume of hydraulic actuators is also relatively large and bulky, so only large and special projects will specifically build and use hydraulic actuators
