Motors are commonly used mechanical equipment in our lives and production. They convert electrical energy into mechanical energy, bringing great convenience and benefits to our production and life. However, if some motors have not been used for a long time, some problems will occur, such as damage, rust, etc. At this time, we need to do some work before putting them into use to ensure the normal operation of the motor. Next, I will introduce to you what needs to be done before putting in a motor that has not been used for a long time.
1. Check the appearance and structure
First of all, we need to check the appearance and structure of the motor to see if there is rust, deformation, looseness, etc., especially the bearing part, whether it is severely worn, whether there is rust and abnormal noise. In addition, check whether the transmission parts, such as belts, gears, etc. are normal.
2. Check the electrical parts
Secondly, we need to check the electrical parts of the motor, including circuits, motor starters, motor windings, capacitors, etc., to see if there are open circuits, false soldering, poor contacts, etc. The insulation condition of the motor winding can be judged by measuring the insulation resistance.
3. Add lubricating oil
Next, we need to add lubricating oil to the appropriate location according to the requirements of the motor to ensure the reduction of friction and wear when the motor is running and extend the service life of the motor.
4. Drying motor
If the motor has not been used for a long time, there may be moisture inside. At this time, we can remove the moisture by drying it. The specific method is to install the motor on the bracket, connect it to the power supply, and let the motor rotate to evaporate the water inside when the current does not exceed the rated current. It usually takes about 12 hours to dry.
5. Carry out trial operation
Finally, we need to conduct a test run. First, conduct a no-load test run to check whether the motor is running smoothly, whether there is overheating, whether there are any abnormal sounds, etc. If everything is normal, perform a test run with load to check whether the performance of the motor is good when running with load.
The above is the work that needs to be done before putting in a motor that has not been used for a long time. Only after these preparations are completed, the motor can ensure normal operation and exert its due benefits. I hope this article can be helpful to everyone, and let us work together to contribute to the beauty of production and life.
