How to maintain the String Excitation Motor Motor Stator Press End Plate Machine?
The maintenance methods of the series excitation motor motor stator press end plate machine are as follows:
1、Daily maintenance
Cleaning: Regularly clear away the dust and debris on the surface and inside of the equipment, especially the stator, rotor, heat sink and other parts, to prevent the accumulation of dust affecting heat dissipation and normal operation. It is recommended to use clean compressed air or soft brush for cleaning, avoid using wet cloth or water to rinse directly, to prevent moisture from entering the internal equipment causing short circuit and other faults.
Fastening check: Check all fasteners on the equipment, such as screws, nuts, bolts, etc., to make sure they are not loose or falling off. If they are loose, they should be tightened in time; if any damaged fasteners are found, they need to be replaced immediately to ensure the structural stability of the equipment.
Wiring check: check whether the wiring of the equipment is firm, with or without damage, aging, burning and other phenomena. For loose terminals, retighten; for damaged wires, must be replaced in a timely manner to ensure a reliable electrical connection to prevent poor contact, leakage and other hidden dangers.
2、Regular maintenance
Lubrication maintenance: According to the frequency of use and working environment of the equipment, regularly add the appropriate amount of lubricant or grease to the bearings, gears, rails and other moving parts of the equipment. Select the appropriate lubricant, and follow the equipment manufacturer's recommendations for lubrication operations, can effectively reduce friction and wear between parts, improve the operating efficiency and service life of the equipment.
Electrical system testing: Use professional electrical testing tools, such as multimeter, megohmmeter, etc., to test the motor's winding, insulation resistance, grounding resistance, etc., on a regular basis. Ensure that the resistance value of the windings is within the normal range, the insulation resistance meets the requirements, and the grounding is good, in order to prevent the motor from short-circuiting, leakage and other electrical failures, and to safeguard the operation of the equipment.
Inspection of mechanical parts: Check the wear and tear of mechanical parts such as stator, rotor, pressure end plate, etc., to see if there are cracks, deformation, excessive wear and tear, etc. For parts that are badly worn or damaged, they should be replaced in time to ensure the normal working accuracy and performance of the equipment. At the same time, check whether the fit gap of the mechanical transmission parts is appropriate, if there is any abnormality, it needs to be adjusted or repaired 23.
Pressure system maintenance: check the pressure components in the hydraulic or pneumatic system, such as oil pumps, cylinders, solenoid valves, etc., to ensure that they work properly and the pressure is stable. Regularly replace the hydraulic oil or filter the air source to prevent oil contamination or air source impurities from affecting the system performance. At the same time, check the accuracy of the pressure sensor and pressure gauge, if there is any deviation, it should be calibrated or replaced in time.
3、Operation monitoring
Temperature monitoring: During the operation of the equipment, pay close attention to the temperature changes of the motor, transformer, controller and other key components. By installing temperature sensors or using tools such as infrared thermometers, measure the temperature of the components on a regular basis to ensure that they are within the normal operating temperature range. If the temperature is found to be abnormally high, the machine should be shut down immediately for inspection, to find out the cause and troubleshooting, to prevent damage to the equipment due to overheating.
Vibration monitoring: Use vibration sensors or vibrometers to monitor the vibration of the equipment and check whether there is any abnormal vibration. Under normal circumstances, the vibration of the equipment should be within the specified range. If the vibration is too large, it may be caused by component imbalance, looseness, wear and tear, etc., and need to stop the machine in time for inspection and repair, in order to avoid the vibration aggravation of the equipment to cause greater damage.
Noise monitoring: pay attention to listen to the sound of the equipment operation, if there is abnormal noise, such as harsh sound, friction, humming, etc., should be promptly shut down for inspection. Abnormal noise may be due to component failure, poor lubrication, foreign objects into the causes, through careful inspection and analysis, to find the source of the noise and take appropriate measures to deal with.
4、Long-term out-of-service maintenance
Clean and dry: Before the equipment is out of service for a long period of time, it should be cleaned completely and ensure that the inside and outside of the equipment are dry and moisture-free. Can use desiccant or ventilation equipment to absorb and exclude moisture in the equipment to prevent equipment rust and corrosion.
Rust prevention treatment: For the metal parts of the equipment, such as the shell, shaft, bolts, etc., you can apply the appropriate amount of anti-rust oil or anti-rust paint for protection to prevent rust and corrosion during the period of decommissioning.
Periodic coiling: During the period of equipment decommissioning, perform a coiling operation on the motor at regular intervals (e.g., every week or every month) to manually rotate the motor shaft so as to make the internal parts of the motor get proper activities and prevent the bearings and journals and other parts from sticking or deforming due to long-term static.
Moisture and dust: Store the equipment in a dry, well-ventilated and dust-free environment, use a dust cover or packing materials to cover the equipment to prevent dust and debris from entering the equipment.
