What are the common sensor failures and their solutions for series-excited motor-motor stator paint dripping machine?
1、Temperature sensor failure
Fault phenomenon:
The display temperature does not match with the actual temperature, which may lead to inaccurate control of drying temperature during the paint dripping process, affecting the drying effect and quality of paint.
Temperature sensor no signal output, so that the drying system can not be adjusted according to the actual temperature, may cause the paint drying incomplete or excessive baking.
Solution:
Calibrate the temperature sensor, use a standard thermometer for comparative measurements, adjust the calibration parameters of the sensor to make the displayed temperature consistent with the actual temperature.
Check whether the connection line of the temperature sensor is loose, broken or short-circuited, if there is any problem, repair or replace the line in time.
If the temperature sensor itself is damaged, you need to replace the new temperature sensor, and to ensure that the installation position is correct, and the measured object is in good contact.
2, level sensor failure
Failure phenomenon:
Liquid level sensor false alarm, showing that the paint level is too low or too high, resulting in the paint pump can not work properly or paint overflow.
Can not accurately detect the liquid level, so that the paint replenishment is not timely, affecting the continuity of paint dripping.
Solution:
Clean the probe of the liquid level sensor, remove the paint and impurities on the surface of the probe to ensure that the probe can accurately detect the liquid level.
Check whether the installation position of the liquid level sensor is correct, whether it is affected by vibration, impact and other impacts and displacement, if necessary, readjust the installation position.
For capacitive level sensors, check whether the capacitance value of the sensor is within the normal range, such as out of range may be sensor damage, need to be replaced.
3, flow sensor failure
Failure phenomenon:
The flow sensor measurement value is inaccurate, resulting in uneven paint dripping, affecting the quality of stator paint dripping.
Flow sensor no flow signal output, so that the drip paint system can not work properly, the stator can not get uniform drip paint.
Solution:
Check whether the pipeline connection of the flow sensor is tight, whether there is any leakage phenomenon, if there is leakage timely repair.
Clean the internal channel of the flow sensor to prevent debris, paint lumps, etc. from blocking the sensor and affecting the measurement accuracy.
Calibrate the flow sensor, operate in accordance with the calibration procedure of the sensor, adjust the measurement parameters of the sensor to ensure that the measurement value is accurate.
4, position sensor failure
Failure phenomenon:
The position sensor is unable to accurately detect the position of the stator, resulting in inaccurate paint dripping position, affecting the effect of paint dripping.
The position sensor is triggered incorrectly, so that the paint dripping system starts dripping paint before the stator reaches the specified position, resulting in the waste of paint and uneven paint dripping.
Solution:
Check the sensing surface of the position sensor for dirt, debris, etc. If there is any, clean the sensing surface to ensure that the sensor can sense normally.
Adjust the installation position and sensitivity of the position sensor so that it can accurately detect the position of the stator.
Check whether the electrical connection of the position sensor is normal, such as loose, broken circuit and other problems in time to repair.
5, photoelectric sensor failure
Failure phenomenon:
The photoelectric sensor can not be sensed normally, resulting in the automated control process of the paint dripping machine failure, such as the inability to automatically start or stop the paint dripping, conveying and other operations.
Photoelectric sensor mis-sensing, so that the paint dripping machine malfunction, affecting production efficiency and product quality.
Solution:
Clean the lens and sensing area of the photoelectric sensor, remove dust, oil and other impurities to ensure that the light can be transmitted and sensed normally.
Check whether the optical path of the photoelectric sensor is blocked, if there is any blocking material clear off in time.
Adjust the sensitivity and detection distance of the photoelectric sensor so that it can accurately sense the target object.
