Advantages, disadvantages and characteristics of electric actuators

advantage:

　　The advantages of electric actuators are convenient energy access, fast signal transmission speed, long transmission distance, convenient centralized control, high sensitivity and precision, easy coordination with electric adjustment instruments, and simple installation and wiring.

    The disadvantage is that the structure is complex, the thrust is small, the average failure rate of the anti-frost level gauge is higher than that of the pneumatic actuator, and it is suitable for places with low explosion-proof requirements and lack of air sources.

Disadvantages:

1. The structure is more complex, and it is more prone to failure, and because of its complexity, the technical requirements for on-site maintenance personnel are relatively higher;

2. The motor runs to generate heat. If the high temperature solenoid valve is adjusted too frequently, it is easy to cause the motor to overheat, produce thermal protection, and increase the wear of the reduction gear;

3. In addition, it runs slower. It takes a long time from the output of a signal from the regulator to the movement of the regulating valve to the corresponding position in response. This is where it is inferior to pneumatic and hydraulic actuators.

Features:

1. Small size: the size is only about 35% of similar products.

2. Light and cheap: the weight is only about 30% of similar products.

3. Anti-corrosion and anti-rust: the bracket, coupling and screw are all made of stainless steel.

4. Protection device: double limit, overheat protection, overload protection (optional).

5. Easy to use: no refueling, no spot inspection, waterproof and rustproof, installation at any angle.　

6. Safety guarantee: Pass 1500V withstand voltage test, F-class insulated motor, safety is guaranteed.

7. Beautiful and generous: aluminum alloy die-casting shell, fine and smooth, and can reduce electromagnetic interference.

8. Reliable performance: Imported products are used for key components such as bearing and mouth electrical components.

9. Powerful functions: intelligent, proportional, on-off, and various signal output types.

10. Intelligent CNC: digital setting, digital setting, high accuracy, self-diagnosis, multiple functions in one machine.

11. Precision and wear resistance: The worm gear output shaft is integrated with special aluminum alloy forging, which has high strength and good wear resistance.

12. Very small return difference: the worm gear output shaft is integrated, which avoids the gap of the key connection, and has high transmission accuracy.

13. Simple matching: It adopts single-phase power supply and external wiring is particularly simple. It can also be used as 380V, DC power supply.

14. Integration: the valve actuator intelligent control module is highly integrated in the electric device body, without the need for an external positioner, etc.

15. Multiple speeds: (partial rotation angular travel) full travel time of 5 seconds, 10 seconds, 15 seconds, 30 seconds, 60 seconds, 100 seconds, etc.
