Eight possible faults and solutions for electric actuators
Solution: Check whether the power supply voltage is correct, check whether the motor is disconnected, and check whether the ten-core plug is disconnected from the end to the end of each line.
Treatment method: Check whether the polarity of the input signal is correct, and check whether the control module is good by the comparison and interchange method.
Treatment method: The parameter setting of the regulator is inappropriate, which will cause the system to produce different degrees of oscillation. According to the manufacturer's instructions or actual use experience, the parameters are revised again.
Treatment method: use AC 2V voltage file to test whether the input end of the control module has AC interference. Check whether the signal line is isolated from the power line, check whether the potentiometer and potentiometer wiring are good, and check whether the feedback component operates normally.
Treatment method: check whether the adjustment of the "zero position" and "stroke" potentiometers is correct, and check the replacement control module to judge.
Treatment method: check whether the function selection switch of the control module is in the correct position, check whether the adjustment of the "zero position" and "stroke" potentiometers is correct, and check the judgment by replacing the control module.
Treatment method: mainly because the sensitivity is adjusted too high, the insensitive area is too small, and it is too sensitive, so that the small loop of the actuator cannot be stabilized and oscillates. The sensitivity can be finely adjusted counterclockwise to reduce the sensitivity; the fluid pressure changes too much, the actuator thrust Insufficient; the choice of regulating valve is large, and the valve often works in small opening.
