How should the brushless motor motor automatic rotor loading machine be maintained?
The following are several important aspects of the maintenance of brushless motor motor automatic rotor loading machine:
1, daily cleaning and inspection
l Cleaning content:
Regularly clean the surface of the equipment, clear off the dust, oil and debris to prevent it from entering the interior of the equipment to affect normal operation. Pay special attention to the surface cleaning of the conveyor rail, bin, loading mechanism and sensors and other parts of the loading machine, because these parts are in direct contact with the rotor or involved in the loading process, and they are prone to accumulating dust and sundries.
When cleaning electrical parts, use dry, non-static cleaning tools, avoid using wet cloth to wipe the electrical components directly to prevent short circuit. For circuit boards, PLCs, relays, etc. in the control cabinet, use compressed air or special electrical cleaners to clean and clear away dust and tiny particles.
l Inspection items:
Check the appearance of the equipment daily for any damage, such as whether there are cracks in the casing and whether the parts are loose or deformed. Check whether the screws are tightened, especially the mechanical connection parts of the loading machine, such as the installation screws of the transmission parts and the fixing screws of the bin, etc. Tighten the loose screws in time to prevent abnormal vibration or affecting the precision of the equipment due to the loosening of the parts.
Check whether the electrical wiring is broken and aging. Check whether the insulation of the wires is intact, whether the joints are firm, for the exposed lines, focus on checking its protection.
2、Maintenance of mechanical parts
l Transmission parts:
Regularly check and maintain the transmission parts such as conveyor belts and chains. For the conveyor belt, check its wear and tear, if the surface is found to be seriously worn, slipping or running phenomenon, the tensioning device should be adjusted in time or replace the conveyor belt. For the chain, check whether its links are loose, deformed or worn, and add the right amount of lubricating oil or grease regularly to ensure the smooth operation of the chain.
Check the mechanical parts of the feeding mechanism, such as gripping claws, suction cups, push rods and so on. Grabbing claw and push rod should check whether it is worn, deformed or cracked, if there is damage should be replaced in time; for the suction cup, check whether its suction is enough, whether the seal is good, if there is leakage need to be repaired or replaced in time.
Check the bearings of the equipment, listen to whether there is any abnormal sound when it is running, if you find that there is a strange sound or rotation is not flexible, it may be bearing wear or poor lubrication. Add grease to the bearings regularly, if the bearings are worn out seriously, new bearings should be replaced in time to ensure the mechanical performance of the equipment.
l Silo:
Clean the debris in the material bin to prevent the rotor from clogging in the bin. Check whether there is any deformation or damage to the structure of the silo, especially the outlet of the silo and the internal guiding device, to ensure that the rotor can be smoothly discharged.
For the silo with a vibrator, check the working condition of the vibrator, including vibration frequency, amplitude is normal, vibration motor is running smoothly, check whether the installation of the vibrator is solid, timely adjustment or replacement of faulty vibrator parts.
3、Maintenance of electrical components
l Motor maintenance:
Check the running status of the brushless motor, including the speed, current and temperature of the motor. Use tools such as multimeter, clamp ammeter and infrared thermometer to measure the operating parameters of the motor to ensure that they are within the normal range. If the motor temperature is too high, the current is abnormal or the speed is unstable, it may be a faulty motor winding, a bearing problem or an abnormal power supply that requires further inspection.
Clean the heat sink of the motor regularly to ensure good heat dissipation. For the junction box of the motor, check whether the wiring is firm to prevent electrical failure due to poor contact.
l Sensor maintenance:
Regularly test and clean all kinds of sensors such as position sensors, counting sensors and proximity sensors. Use professional test tools to check whether the output signals of the sensors are normal or not, if the signals are abnormal, deal with them in accordance with the solutions for sensor failures.
Clean the sensing area of the sensor to avoid dust, oil, etc. affecting its normal operation. Check whether the installation position of the sensor is offset, such as offset needs to be re-adjusted to ensure that it accurately senses the position of the rotor, the number of information.
l Control unit maintenance:
Check and maintain the PLC, controller and other control units. Check whether the input and output signals of the PLC are normal, check the operation of the PLC program through the programming software or the monitoring interface of the equipment, and carry out timely debugging and modification of the program if abnormal operation is found.
Check whether the display interface of the controller displays information normally, and whether the operating parts such as buttons and knobs of the controller are flexible and reliable. Regularly back up the parameters and programs of the controller to prevent data loss due to equipment failure.
4、Lubrication and cooling system maintenance
l Lubrication system:
Ensure that the lubrication system of the equipment works properly and check the level and quality of lubricant or grease regularly. For the loading machine with centralized lubrication system, check the operation of the lubrication pump to ensure that it can provide lubrication for the key parts of the equipment on time and in quantity.
Replenish or replace the lubricant or grease in a timely manner according to the equipment's usage time and operating environment. Different parts may require different types of lubricants. Make sure that the lubricant used meets the requirements of the equipment to avoid damage to the equipment caused by the use of improper lubricants.
l Cooling system (if any):
For the loading machine equipped with a cooling system, check whether the piping of the cooling system is smooth and the coolant is sufficient. Check whether the cooling fan operates normally and whether the cooling water pump works normally to prevent the equipment from being damaged due to overheating.
Regularly clean the radiator of the cooling system, clear away the scale or impurities in the cooling pipes to ensure the cooling effect and extend the service life of the equipment.
5、Regular calibration and adjustment
l Equipment calibration:
Regularly calibrate the equipment, including calibrating the position sensor, the position of the feeding mechanism, and the lowering position of the bin. Use professional calibration tools to adjust the key parameters of the equipment to an excellent state according to the technical specifications of the equipment to ensure the feeding accuracy and positional accuracy of the feeding machine.
Calibrate the speed, torque and other parameters of the motor to ensure that the performance of the motor meets the production requirements. By adjusting the controller parameters of the motor, the motor can run stably under different loads to ensure the feeding speed and stability.
l Software parameter adjustment:
For the control software of the feeding machine, check whether the setting parameters of the software are correct. According to the change of production process, adjust the parameters such as feeding speed, feeding quantity and time interval in the software.
Check the communication settings of the software to ensure that the communication between the software and the equipment is normal. Setting and adjusting the alarm parameters in the software to ensure that accurate alarm information can be issued in time when the equipment is abnormal, which is convenient for the operators to deal with the faults in time.
Through all of the above maintenance measures, you can ensure that the brushless motor motor automatic rotor loading machine long-term stable operation, improve the service life of the equipment and production efficiency, reduce the occurrence of failures.
