In many projects, damper actuators can simply realize fast linear cyclic motion, with simple structure and convenient maintenance. At the same time, they can be used in various harsh working environments, such as explosion-proof requirements, dusty or humid working conditions.
The advantages of damper actuators mainly include the following four aspects:
(1) Large load, can adapt to applications with high torque output.
(2) Rapid action and fast response.
(3) Good adaptability to working environment, especially in harsh working environments such as flammable, explosive, dusty, strong magnetic, radiation and vibration, which is superior to hydraulic, electronic and electrical control.
(4) The motor is easily damaged when the stroke is blocked or the valve stem is stuck.
What is the difference between damper actuators and electric actuators?
Pneumatic systems and electric systems are not mutually exclusive. Damper actuators can simply realize fast linear cyclic motion, with simple structure and convenient maintenance. At the same time, they can be used in various harsh working environments, such as explosion-proof requirements, dusty or humid working conditions. However, when the force increases rapidly and accurate feedback is required, electric drives with servo motors have advantages. For applications that require accurate, synchronous operation, adjustable and specified feedback programming, electric drives are a better choice. The electric drive system composed of servo or stepper motors with closed-loop feedback controllers can supplement the deficiencies of pneumatic systems.
The actuator and adjustment mechanism of the damper actuator are a unified whole. Its actuators are diaphragm type, piston type, scotch fork type and gear rack type. The piston type has a long stroke and is suitable for occasions requiring a large thrust; while the diaphragm type has a small stroke and can only directly drive the valve stem. The scotch fork type pneumatic actuator has the characteristics of large torque, small space, and a torque curve that is more in line with the torque curve of the valve, but it is not very beautiful; it is often used on valves with large torque.
The gear rack type pneumatic actuator has the advantages of simple structure, stable and reliable operation, and explosion-proof. It is widely used in power plants, chemical industry, oil refining and other production processes with high requirements.
