How to maintain the brushless motor motor automatic rotor magnetizer?
Maintenance of a brushless motor motor automatic rotor magnetizer is critical to its performance, accuracy, stability and service life. The following are the detailed maintenance suggestions from mechanical, electrical, software and other aspects:
First, the mechanical part of the maintenance
1、Cleaning
Regularly (e.g., weekly) clean up the appearance of the magnetizer and the internal mechanical structure, remove dust, iron filings and other impurities. You can use a clean soft cloth to wipe the surface, for the internal hard to reach parts, you can use compressed air to blow clean.
Pay special attention to the rotor clamps and guide rails, the cleanliness of these parts will affect the positioning accuracy and smooth movement of the rotor. A small amount of antirust oil can be applied after cleaning to prevent parts from rusting.
2、Lubrication
In accordance with the requirements of the equipment manual, lubricate the transmission parts of the magnetizer, such as the silk rod, guide rail, bearings and so on, on a regular basis. For example, for the silk rod and guide rail, add special grease once a month; for the bearings, replace the grease once a quarter.
Note that the choice of grease should be matched with the working environment and requirements of the equipment, to avoid the use of inappropriate grease resulting in damage to the components.
3、Fastening
Regularly check and tighten the mechanical connection parts of the magnetizer, such as bolts and nuts. Due to the vibration caused by the operation of the equipment, these connection parts may loosen, resulting in a decrease in precision or failure of the equipment. It is generally recommended to perform a complete tightening check once a month.
For the key parts of the bolts, you can use torque wrenches in accordance with the specified torque for tightening to ensure a solid connection.
4、Component inspection and replacement
Regularly check the wear and tear of mechanical parts, such as the clamping claws of the rotor fixture, guide slider and so on. If serious wear is found, it should be replaced in time to ensure the accuracy and reliability of the equipment.
For some wearing parts, such as belts, chains, etc., to regularly check the tension and wear, if necessary, to adjust or replace.
Second, the electrical part of the maintenance
1、Cleaning and inspection
Regularly (quarterly) clean up the dust inside the electrical control cabinet to prevent the accumulation of dust leading to poor heat dissipation or short-circuit electrical components. Brush and compressed air can be used to clean up.
Check whether the connection of the electrical line is firm, there is no loose, aging, broken and other phenomena. For loose terminals, tighten them in time; for aging or broken wires, they should be replaced in time.
2、Insulation test
Use insulation resistance meter to test the insulation resistance of electrical equipment every year to ensure good insulation performance. General requirements of the insulation resistance value is not less than the specified standard, otherwise there may be a risk of leakage, need to be further checked and dealt with.
Before testing the insulation resistance, make sure that the equipment has been disconnected from the power supply, and the electrical components are fully discharged.
3、Maintenance of electrical components
Regularly check the working condition of electrical components, such as contactors, relays, fuses, etc.. For abnormal heat, contact wear and other components, timely maintenance or replacement.
For electronic components, such as chips and capacitors on the circuit board, pay attention to prevent static electricity damage. When carrying out maintenance, anti-static bracelets should be worn.
4、Power supply maintenance
Ensure that the power supply of the magnetizer is stable to avoid excessive voltage fluctuations causing damage to the equipment. A voltage regulator or uninterruptible power supply (UPS) can be installed to protect the equipment.
Regularly check the contact of the power plug and socket to avoid poor contact leading to equipment failure.
Third, the software part of the maintenance
1、System update
Pay attention to the update information of the magnetizer software, and contact the equipment manufacturer in time to get the new software version. It is generally recommended to upgrade the software under the guidance of the equipment manufacturer to repair software vulnerabilities, improve performance and add new features.
Before performing the software upgrade, backup important data and parameters to prevent data loss.
2、Data backup
Regularly (e.g., monthly) backup the operation data and process parameters of the magnetizer and store them in external storage devices. In this way, in case of software failure or data loss, the data can be recovered in time to reduce the loss.
Backup data should be properly stored to prevent data damage or loss.
3、Virus protection
Install reliable antivirus software in the control system of the magnetizer and update the virus database regularly. Avoid using storage devices of unknown origin in the control system of the equipment to prevent virus infection.
Regularly scan the system for viruses to ensure the normal operation of the software system.
Fourth, the operating environment maintenance
1、Temperature and humidity control
Place the magnetizer in a temperature and humidity suitable environment, the general temperature control at 20 ℃ - 30 ℃, relative humidity control at 40% - 70%. Excessive temperature will affect the performance of electrical components, while excessive humidity may cause equipment rust and short circuit.
Air conditioning and dehumidification equipment can be installed to regulate the temperature and humidity of the environment.
2. Dust and moisture prevention
Keep the workplace of the magnetizer clean to avoid dust and debris from entering the equipment. Dust-proof curtains or air purification equipment can be installed in the workplace.
For humid environment, take moisture-proof measures, such as placing desiccant around the equipment.
3. Avoid vibration and interference
The magnetizer should be installed in a place far away from the source of vibration and electromagnetic interference, such as large mechanical equipment, transformers and so on. Vibration will affect the accuracy of the equipment, while electromagnetic interference may lead to malfunction of the electrical system.
If vibration and interference cannot be avoided, damping and shielding measures can be taken, such as installing damping pads and using shielded cables.
V. Operator training and management
1、Training
Provide professional training to the operators of the magnetizer to make them familiar with the operation methods, maintenance points and precautions of the equipment. The training includes the basic principles of the equipment, the use of the operator interface, common faults, etc. The operator should pass the examination and be qualified to operate the machine.
Operators should be qualified after examination before they are allowed to operate the equipment.
2、Operation standardization
Formulate strict operating procedures and require operators to operate in strict accordance with the procedures. For example, equipment inspection should be carried out before starting the machine, and the equipment should be cleaned and maintained after shutting down the machine.
Prohibit the operator to change the parameters and settings of the equipment at will, if necessary, should be under the guidance of professionals.
3、Record and feedback
Operators are required to make a good record of the operation of the equipment, including the equipment's start-up time, shutdown time, operating parameters, fault conditions. Through the analysis of the operation records, the potential problems of the equipment can be found in time and appropriate measures can be taken to deal with them.
Encourage operators to give timely feedback on the abnormal situation of the equipment and use suggestions for timely maintenance and improvement.
If the equipment failure still cannot be solved by the above ways and means, please contact the technical specialist of Xinhui electromechanical through the page chat tool for help.
