How should the DC brushed motor motor automatic press bearing magnetizer be maintained?
The maintenance of DC brushed motor motor automatic receivers can be carried out in the following aspects:
I. Daily maintenance
l Appearance cleaning
At the end of each day's work, use a clean rag to wipe the body of the reclaimer and clear away the dust, material residues and other debris on the surface. This not only keeps the equipment tidy, but also prevents debris from entering the interior of the machine and affecting its normal operation.
For the surface of the motor, sensors and other key components, pay special attention to cleaning, to avoid the accumulation of dust affecting heat dissipation or signal transmission.
l Check the connection parts
Check whether the connection bolts and nuts between various parts of the equipment are loose. Focus on checking the connection between the motor and the receiving device and transmission parts, and tighten them in time if they are loose. Loose connections may lead to increased vibration of the equipment, wear and tear of parts or even fall off, affecting the stability of the equipment.
Check whether the wire connections are firm, including the power plug, sensor signal wire, motor control wire and so on. If the plug is found to be loose, it should be re-inserted and make sure that the contact is good; for broken wires, they should be wrapped or replaced in time to prevent leakage or signal interruption.
l Running status check
Before starting the equipment, manually disk the motor shaft to check whether the motor can rotate smoothly. If there is a feeling of stagnation, it is necessary to further check whether there are foreign objects or damaged parts inside the motor.
After starting the equipment, observe whether the running sound of the motor is normal. Under normal circumstances, the motor running sound is smooth, no abnormal friction, impact sound or whistling sound. If there is any abnormal sound, stop the machine immediately for inspection to avoid the expansion of the fault.
Observe whether the material collecting process of the reclaimer is smooth, whether the material conveying is normal, and whether there is any jamming or clogging. If you find that the collection of material is not smooth, we should promptly clean up the material channel or check whether the conveying parts are damaged.
Second, regular maintenance (weekly or monthly)
l Lubrication maintenance
Lubricate the transmission parts of the equipment, such as gears, chains, pulleys and so on. According to the instruction manual of the equipment, choose suitable lubricant, such as lubricating oil or grease, and use a grease gun or brush to apply the lubricant evenly on the surface of the transmission parts. Lubrication can reduce the friction between parts, reduce wear and prolong the service life of the equipment.
Regularly check the lubrication effect, if you find that the lubricant is dry or contaminated, you should promptly clean and re-add lubricant. At the same time, pay attention to the amount of lubricant used, to avoid too much lubricant to cause slippage between parts or contaminated material.
l Electrical system check
Check the wear and tear of the brushes of the motor. Brushes are the key components of DC brush motors, and they will wear out gradually with the increase of usage time. When the brush length is less than the specified value, the brushes should be replaced in time to ensure normal operation of the motor. When replacing brushes, pay attention to selecting brushes that match the motor model and install them according to the correct installation method.
Use an insulation resistance meter to check the insulation resistance of the motor windings. Low insulation resistance may cause the motor to short-circuit and affect its performance. If the insulation resistance is found to be out of compliance with the requirements, it is necessary to further check whether the motor windings are damp or damaged, and dry or repair them if necessary.
Clean the inside of the electrical control cabinet. Periodically open the electrical control cabinet and use a hair dryer or soft brush to remove dust and debris from the interior. Dust buildup can cause poor heat dissipation, short circuits or signal interference in electrical components, so it is important to keep the inside of the control cabinet clean. At the same time, check whether the electrical components are firmly connected, whether there are signs of overheating and discoloration, and if there is any abnormality, it should be dealt with in time.
l Sensor calibration and cleaning
For various sensors such as material level sensors and speed sensors, calibrate them regularly. The calibration method can be based on the type of sensor and equipment requirements. For example, for the material level sensor, you can use the standard material level height to check whether the output signal of the sensor is accurate; for the speed sensor, you can use the tachometer to compare the calibration. Calibration can ensure the measurement accuracy of the sensor and the normal operation of the skimmer.
Clean the surface of the sensor. The surface of the sensor may be contaminated by materials, dust or oil, affecting its detection performance. Use a clean damp cloth or special cleaner to gently wipe the sensor probe, lens and other parts to remove dirt, but be careful to avoid damage to the sensor.
III. Long-term maintenance (every six months or a year)
l Mechanical parts inspection and replacement
Conduct a full inspection of the mechanical parts of the equipment, including bearings, shafts, rollers, etc. Check the bearings for signs of wear, looseness or overheating, and replace the bearings if there are any problems. For shafts and rollers, check whether there is any wear, deformation or corrosion on their surfaces, and repair or replace them if necessary.
Check the wear and tear of the conveyor belt, chain and other parts of the reclaimer. If the wear is serious and exceeds the specified limit, it should be replaced in time to avoid breakage and other faults during the working process, which will affect production.
Check whether the frame and shell of the equipment are deformed, cracked and so on. Damage to the frame and shell may affect the overall structural stability of the equipment, which needs to be repaired or reinforced in time.
l Motor Maintenance and Repair
Perform all maintenance on the motor, including disassembling the motor shell and cleaning the dust and debris inside the motor. At the same time, check the stator and rotor of the motor for wear and tear, short circuits or other damage. If problems are found, the motor should be repaired or replaced depending on the extent of damage.
Check the motor's cooling system, such as heat sinks and fans. Make sure that the heat sink is not clogged with dust and that the fan can operate properly. Poor heat dissipation will cause the motor to overheat and reduce its performance and life, so it is very important to maintain good heat dissipation conditions.
l Control system upgrade and backup
Check whether there is an updated version of the control system software of the reclaimer. If there is a new version of the software release, and the update contains performance optimization, functional improvement or vulnerability repair, etc., the control system should be upgraded in a timely manner. Back up the original system parameters and programs before upgrading, in order to prevent data loss due to unforeseen circumstances during the upgrade process.
Backup the important data of the control system, such as parameter settings and operation records. You can use external storage devices, such as USB flash drives, removable hard disks, etc., and regularly back up the data to these devices so that they can be recovered in time when the equipment malfunctions or data loss occurs.
