Related introduction of angle travel electric actuator

These two types of actuators previously consisted of servo reducers and actuators. Electric actuators can be divided into three types: angular stroke, straight stroke and multi-turn type. The role of angular stroke electric actuators is to accept conditioners. Or other instrument's current value of 0 ~ 10, 4 ~ 20mA or 1 ~ 5V voltage.

After the actuator becomes displacement thrust or corner moment, in order to operate the switch, valve, etc., to complete the obligation of automatic adjustment, today's inorganic-electric integrated intelligent structure, their structure, task principle and application method are similar, the difference is only The reason is that one input displacement (thrust) and one input angle (moment). \

The selection of electric actuators with angle travel determines the electrical parameters according to the selected electric actuator. Because the electrical parameters of different manufacturers of electric actuators with different angle travel are different, it is common to determine the electrical parameters when designing and selecting, mainly the motor power. , Extra current, secondary control loop voltage, etc., are often negligent in this regard. As a result, the control system and the electric actuator parameters are not matched to form the task of time-open trip, fuse blown, thermal overload relay maintenance and other shortcomings. Angle travel electric The rotation of the input shaft of the actuator is less than one turn, that is, less than 360 degrees; usually, the opening and closing process control of the valve is completed at (0 ~ 90) degrees. The angular stroke electric actuator is used to control butterfly valves, ball valves, plug valves and other valves. Direct connection type, base crank type
