What are the common sensor failures and their solutions for brushless motor motor manual stator slot paper machine?
Brushless motor motor manual stator slot paper machine common sensor failure and its solutions are as follows:
First, the paper feed detection sensor failure
1, paper detection failure
Fault Description: The paper feed detection sensor can not detect the presence of paper, resulting in abnormal operation of the paper feeding mechanism, there may be idle or continuous paper feeding non-stop.
Solution: Check the sensor surface whether there is dust, paper and other pollutants, such as clean; check whether the sensor is installed in the correct position, such as offset is re-adjusted to the appropriate position; test the sensor's connecting wire is loose or damaged, if there is a problem, then tighten or replace; if the sensor itself is damaged, you need to replace the new sensor.
2, false detection
Fault Description: The sensor in the absence of paper or paper normal delivery, the wrong detection signal, resulting in equipment operation disorder.
Solution: Check whether the sensitivity of the sensor is set too high or too low, re-adjust the sensitivity parameters; check whether there are sources of interference around, such as electromagnetic interference, etc., if any, then take shielding measures or adjust the wiring of the equipment; check the paper material, color, etc., whether the sensor detection has an impact on the sensor, if necessary, to replace the appropriate sensors or to adjust the detection method.
Second, the positioning sensor failure
1、Inaccurate positioning
Fault description: The positioning sensor can not accurately determine the position of the stator slot paper, resulting in slot paper position deviation during processing, affecting product quality.
Solution: calibrate the positioning sensor to ensure the accuracy of its measurement; check whether the sensor mounting base is firm, if loose, then fasten; see whether the mechanical transmission components are worn, excessive gap and other issues, if any, then repair or replacement; check the electrical control system with the positioning of the correct parameter settings, if there is an error, then adjust.
2、Sensor signal instability
Fault Description: The output signal of the positioning sensor is sporadic or fluctuates greatly, resulting in incoherent or inaccurate positioning action.
Solution: Check whether the sensor's power supply is stable, whether the voltage is within the prescribed range, if there is a problem, then check the power supply circuit and repair; check whether the sensor's signal line is broken, poor contact and so on, if any, then repair or replacement; check whether the sensor's working environment temperature, humidity and so on to meet the requirements, such as not in line with the improvement of the environmental conditions; to consider the sensor whether the aging, if possible, then Replacement of new sensors.
Third, the tension sensor failure
1, tension detection deviation
Fault Description: Tension sensor measured paper tension and the actual tension does not match, resulting in paper in the delivery process is too loose or too tight, affecting the flatness of the groove paper and processing accuracy.
Solution: Re-calibrate the tension sensor to ensure accurate measurement; check whether the installation of the tension sensor is correct, whether it is interfered by additional external forces, if any, then adjust and exclude; check whether the parameter settings of the tension control mechanism is reasonable, if any problem, then optimize the adjustment.
2、Tension sensor no signal output
Fault description: The tension sensor suddenly has no signal output during the working process, resulting in the tension control system can not work normally.
Solution: Check whether the sensor power supply is normally connected, whether the fuse is blown, if there is a problem, then repair the power supply circuit; check whether the sensor signal line is broken or short-circuited, if there is a repair; check whether the sensor itself is damaged, you can use a multimeter and other tools for testing, such as damage to the replacement of new sensors; check and sensor connected to the controller or amplifier is working properly, if there is a failure, then repair or replacement. Repair or replacement.
Fourth, counting sensor failure
1, inaccurate counting
Fault description: The counting sensor is inaccurate in counting the number of paper in the stator slot, which leads to discrepancy between the production quantity and the actual quantity, affecting production management and quality control.
Solution: Check whether the installation position of the counting sensor is appropriate to ensure that it can accurately detect the passage of each stator slot paper; adjust the sensitivity of the sensor and the trigger threshold, so that it can stably count the target; check whether the sensor's counting logic is set correctly, if there is an error, then modify it; clean up the sensor surface of the dust and debris, to prevent it from affecting the detection effect.
2、Counting interruption
Fault Description: The counting sensor suddenly stops counting during the counting process, resulting in incomplete counting data.
Solution: Check whether the sensor power supply and signal lines are normal, such as loose, disconnected and other issues are repaired; see whether the sensor is subject to strong electromagnetic interference, such as anti-interference measures, such as increased shielding, filtering, etc.; check whether the sensor's operating temperature is too high or too low, beyond its normal operating range, such as the improvement of heat dissipation or heat preservation measures; check the counting sensor software program whether there are loopholes or errors, if any, make changes; clean up the surface of the sensor to prevent the counting data incomplete. Check whether there are loopholes or errors in the software program of the counting sensor, if so, update or repair.
