1. Electrical system inspection
Check the contactor contacts: ensure that the moving and static contacts of the contactor are in good contact to avoid the motor running in phase loss due to poor contact, thereby burning the motor.
Check the cable insulation: perform cable insulation tests regularly to avoid phase-to-phase or grounding faults due to reduced insulation level.
Check the relay protection device: ensure that the appearance of the relay protection device is intact, the terminal is tight, and there is no hot part with poor contact.
2. Motor body maintenance
Lubrication and grease inspection: regularly add an appropriate amount of lubricating oil to the motor bearing to reduce bearing wear.
Cleaning and tightening: regularly clean the dust and oil on the surface of the motor, and tighten the bolts of the motor, including the screws of the foot, end cover, bearing cover and other parts.
Check the waste oil: clean the waste oil in the motor waste oil box, and judge the bearing rotation and lubrication according to the color and amount of the waste oil.
3. Regular inspection and maintenance
Minor repair inspection: regularly check the power cord and signal line of the motor, and perform insulation wrapping or replacement in time to avoid short circuit failure.
Overhaul inspection: Regularly dismantle and inspect the motor bearings and bearing chamber end covers for wear, and check whether the stator and rotor are overheated, worn, or slot strips are broken.
Preventive tests: Regularly conduct preventive tests such as insulation resistance and absorption ratio tests, DC microresistance tests, and DC withstand voltage tests to detect insulation defects in a timely manner.
4. Safety and environment
Keep the working environment clean and tidy: avoid accumulation of debris, excessive humidity, etc. to ensure the normal operation of the equipment.
Pay attention to safety devices: Before debugging and using the shearing machine, carefully check whether the safety devices of the equipment are intact.
