1. The daily operation environment of garage doors should be dry and not in a humid environment. The appearance of motors should be clean, especially the air intake should not be hindered by impurities such as dust and fibers.
2. Ensure that the garage door motor has good smoothness in the operation process. Generally speaking, when the garage door motor runs every 5000 hours or so, it is necessary to replace or replace the smooth grease. If the bearing is found to be overheated or smooth degeneration in operation, it should be timely hydraulically or smoothly greased. When replacing the grease, the old grease should be removed first, and the oil groove of the bearing and bearing cover should be washed with gasoline, then the grease should be filled in one-second of the cavity between the inner and outer rings of the bearing.
3. Once it is found that the vibration and noise of motor running in garage doors increase significantly, it is clarified that the life of motor bearings has reached the limit. At this time, it is necessary to check whether the radial clearance of bearings can reach the relevant value and replace the new motor bearings in time.
4. When the thermal maintenance of the garage door motor is in continuous vibration, it is necessary to find out the direction of the fault first, to see whether the motor is overloaded or the setting value of maintenance and installation is too low, and to put it into normal operation after the fault is eliminated.
5. If the garage door motor breaks down and needs to be disassembled, the rotor can be removed at the extension end or non-extension end of the shaft. Nanchang Minghe advocates that if it is not necessary to unload the fan, it is more convenient to remove the rotor from the non-axle extension end. If it is necessary to withdraw the rotor from the stator, care should be taken to avoid damaging the stator winding or insulation.
