1. The actuator does not operate, but the control module power and signal lights are on.
Axial flow valve manufacturer's processing method: check whether the switching power supply working voltage is appropriate; whether the motor is disconnected; the ten-core power plug from the end to each line terminal equipment is disconnected; the motor, resistor, capacitor each power plug is Not good; it is not good to use the comparison exchange method to distinguish modules.
2. The actuator does not move, the power light does not light up.
Axial flow valve manufacturer's processing method: check whether the input data signal optical rotation is appropriate; whether the module is distinguished by the comparison method.
3. Adjusting the system parameters improperly causes the actuator to oscillate frequently.
The processing method of the axial flow valve manufacturer: the parameter setting of the regulator is not suitable, which will cause the system to generate different degrees of oscillation. For single-loop regulation systems, the proportional band is too small, the integration time is too short, and the differential time and differential gain are too large to cause system oscillation. These parameters can be reasonably selected through the system tuning method to keep the loop stable.
4. The actuator motor generates heat quickly, oscillates and crawls, and stops in a short time.
Axial flow valve manufacturer processing method: use communication 2V working voltage file test module type input terminal is not AC interference; check power cord is not and power plug protection; resistor and resistor wiring is not good; feedback component posture is Not everything is ok.
5, the actuator moves into, crawls, and moves slowly.
Axial valve manufacturer processing method: Check whether the signal action time from the operator is correct.
6. The actuator position feedback signal is too large or too small.
Axial valve manufacturer processing method: check the "zero return" and "stroke arrangement" resistor adjustment is not appropriate; replace the module resolution.
7. After the signal is added, the actuator is fully open or fully closed, and the limit is not stopped.
Axial valve manufacturer processing method: check whether the function of the module knob is in the proper part; "zero return" and "stroke arrangement" resistor adjustment is not appropriate;
8. The actuator oscillates and sings.
The processing method of the axial flow valve manufacturer: the root cause sensitivity is emphasized too high, the failure zone is small, and the dexterity is too dexterous, resulting in the small control loop of the electric actuator not being stable and causing oscillation, and the sensitivity resistor can be adjusted in the opposite direction to reduce the sensitivity. The hydrodynamic working pressure changes greatly, the electric actuator thrust is not enough; the adjustment valve selection becomes larger, and the valve often works in a small opening degree.
9. The actuator does not operate normally, but the motor does not stop after the limit switch is actuated.
The processing method of the axial flow valve manufacturer: check whether the limit switch and the limit switch wiring are faulty; replace the control module to judge.
10. The actuator is broken.
Axial valve manufacturer's treatment method: Check whether part of the internal actuator of the electric actuator is destroyed or not; whether the "zero return" and "stroke" resistor adjustment is appropriate; whether the travel switch is appropriate.
