Electric pneumatic valve actuator is to realize the electric pneumatic valve program control, automatic control and remote control of drive control device.
Electric pneumatic valve movement process controlled by the stroke, torque, etc, due to the working characteristic of electric pneumatic valve and utilization depends on the type and characteristics of pneumatic valve, so the correct selection of electric pneumatic valve actuator is very important to prevent overload.
the output torque of actuators is one of the important parameters choice of electric actuator. The output torque of the actuator should be selected 1 pneumatic valve operating torque. 2 to 1. 5 times. Secondly, according to the different conditions of use of pneumatic valve, select the appropriate opening and closing speed, prevent the pneumatic valve actuator opening and closing speed is too fast and produce water hammer.
electric pneumatic valve actuator has its special requirements, which must be able to limit torque ( Axial force) And the rotation Angle. When determining the specifications of the electric installation, but also determine the control torque. In general, when the motor running in a due time will not overload. But the overload may be caused by the following: one is low voltage power supply, unable to obtain the required torque, the motor stop running; Second, improper adjustment torque limit institutions, make it is greater than the stop torque, lead to continuous torque is too big, make the motor stop running; 3 it is intermittent use, cause heat accumulation, allow more than motor temperature rise; Four is limit circuit fault for the moment, make the torque is too large; Five is to use the environment temperature is too high heat capacity of the motor is less.
1, the environment temperature should be controlled in - 25℃- Between 70 ℃.
2, explosion-proof electric pneumatic valve should be in the current is not stable, environmental corrosion, flammable and explosive, special medium, long time no maintenance and so on occasion. Due to the complexity of the motor structure, failure, should not be removed, so as to avoid an accident.
3, under any circumstances are not allowed to beat or electric pneumatic valve assembly.
