Advantages Of Explosion-proof Electric Actuators in Use
The explosion-proof electric actuator is a new generation of angular stroke electric actuator, which uses worm gear and worm reduction mechanism and has locking function. Equipped with a motor and handwheel, it can perform both electric and manual operations, suitable for small and medium-sized butterfly valves, ball valves, plug valves, and similar equipment with 90 ¡ã rotation. Equipped with stroke control and torque limiting mechanisms. The actuator adopts a top mounted structure, reducing the connection bolts of the valve body itself under high pressure and large diameter conditions, enhancing the reliability of the valve and overcoming the impact of system weight on the normal operation of the valve.
Advantages of using explosion-proof electric actuators:
1. Small size, light weight, and actuator with the same shaft torque, weighing only 1/3 of DKJ and DKZ, with a volume of 1/2 of similar products. The rated output torque of the electric actuator is 600Nm, and the total weight is only 10.0 kilograms.
2. High precision: The careful design of electronic circuits enables the servo motor to cut off the power supply in advance and reverse the power supply. Electric braking ensures positioning accuracy and effectively reduces dead zones and self-excitation.
3. High reliability: Carefully designed and reliable electronic brake circuits can reduce mechanical wear and system self excitation. Significant technological breakthroughs have been made in overcoming surge voltage and protecting non-contact switches. It adopts its innovative design of solid-state relay SSR, which has a current rise rate suppression circuit and a voltage rise rate suppression circuit, so its load capacity and resistance ability are strong. Strong anti-interference performance adopts high-precision and low-power electromagnetic isolation technology, achieving isolation between current input signal and position output, electromagnetic radiation, effectively preventing power frequency and common ground interference, and can be directly used.
4. More innovative points: Because only non-contact power switches can achieve maintenance free, long-lasting, and frequent startup, only non-contact power switches can achieve fast conduction, cutoff, and precise positioning, while also abandoning the method of mechanical friction braking. The successful use of advanced braking technology has doubled sensitivity and control, reducing maintenance workload.
5. Protection function: The protection level of the product is IP67, and customers can choose orders up to IP68 to prevent motor overheating, set motor overheating protection, and protect motor limits.
