The manufacturer of Nanyang explosion-proof motors stated that in order to ensure the normal operation of high-voltage motors, in addition to using them according to operating procedures, they should also conduct punctual inspections and do a good job in protecting high-voltage motors. This can prevent defects from occurring and ensure that the motor can operate.

1. Clean the high-voltage motor. Timely remove dust and oil sludge from the outside of the high-voltage motor frame. If the environment is dusty, clean it once a day.

2. Check and clean the high-voltage motor wiring terminals. Check if the wiring screws of the junction box are loose or burnt.

3. Check the screws of each fixed part, including foundation screws, end cover screws, bearing cover screws, etc. Tighten the loose nuts.

4. Check the transmission equipment, belt pulleys or couplings for signs of momentum, damage, and robustness of the equipment; Is the belt and its connecting buckle intact.

5. The motor advocates that the equipment should also be cleaned of external dust and dirt in a timely manner, the contacts should be cleaned, and all wiring parts should be checked for burn marks and whether the grounding wire is excellent.

6. Inspection and protection of bearings. The manufacturer of Nanyang explosion-proof motor stated that the bearings should be cleaned and replaced with lubricating grease or oil after a period of use. The time for cleaning and oil change should depend on the operating condition, working environment, cleanliness level, and lubricant type of the motor. Generally, every 3-6 months of operation, it should be cleaned and replaced with lubricating grease from the beginning. When the oil temperature is high, motors with poor environmental conditions and high dust content may need to be cleaned and replaced frequently.

7. Inspection of insulation condition. The insulation adjustment of insulation materials varies depending on the degree of monotony, so it is very important to check the monotony of the motor winding. The humid working environment of the motor and the presence of corrosive gases in the working room can damage the electrical insulation. A common drawback of winding grounding is insulation damage, which causes the live part to collide with metal parts such as the casing that should not be live. This defect not only affects the normal operation of the motor, but also endangers personal safety. Therefore, in the use of motors, insulation resistance should be checked frequently, and attention should be paid to checking whether the grounding of the motor casing is reliable.

In addition to the above items for punctual protection of high-voltage motors, major repairs are required after one year of operation. The purpose of major maintenance is to inspect and protect the motor once, remove dust and dirt from the motor surface, and check its wear condition. Generally speaking, the operating life of high-voltage motors is very long, as long as the correct application, protective insurance, and timely handling of defects are used.
