Seven precautions for high voltage dc motor refueling
When the amount of oil is judged in the state of DC motor operation, the difference from the actual amount of oil is relatively large. The amount of oil should be measured in the state of stopping operation and an appropriate amount of DC motor lubricating oil should be added.
7 notes for DC motor refueling:
1. Disconnect from the DC motor or disconnect the main power supply, and then wait until it is cooled to the remaining temperature (should be warm when changing oil).
2. Place a suitable oil-plated plate at the bottom of the DC motor oil drain hole.
3. Loosen and remove the oil plug screw plug, the ventilator and the oil drain plug.
4. Discharge all the remaining lubricating oil in the DC motor and remove impurities such as metal particles in the chassis.
5. After the removal, install the oil drain plug as it is (to be tightened).
6. Write the same grade of lubricating oil from the oil filling hole, pay attention to the amount of increase, according to the increase of the oil mark, can not add more but can not increase.
7. After adding the oil, tighten the oil hole screw plug and the aerator.
