Valve electric actuator characteristics

Jun 19, 2020

As the name implies, electric actuators are powered by electricity, and use single-phase or spindle motors to drive gears or worm gears to output linear or rotary motion. The electric actuator can output a relatively constant driving force, and has strong anti-deviation ability. The control accuracy is simpler than that of the pneumatic actuator. It has the characteristics of easy operation and easy remote control, but its structure is complicated, it is easy to load and malfunction, and positioning often occurs Low precision, over-opening and closing, motor burnout, gear box wear, etc., the maintenance cost is very large. Excessive adjustment will cause the motor to heat up, and the reduction gear is easy to wear. Therefore, the electric actuator runs slowly, it is difficult to achieve a large driving force, and there are problems such as difficulty in implementing over-protection, poor position, and the like.
