Knowledge Introduction of Garage Door Motor Maintenance
1、车库门的日常使用环境应保持干燥，不得处于潮湿的环境中，电机的表面应保持清洁，特别是进风口不得受尘土、纤维等杂质的阻碍。
1. The daily use environment of garage door should be kept dry, not in humid environment, and the surface of motor should be kept clean, especially the air intake should not be hindered by impurities such as dust and fibers.
2、保证车库门电机在运行过程中有良好的润滑。一般来说，车库门电机运行每5000小时左右，就要补充或更换润滑脂，若运行中发现轴承过热或润滑变质时，应及时液压或换润滑脂。更换润滑脂时，应先清除旧的润滑油，并用汽油洗净轴承及轴承盖的油槽，然后将润滑脂填充在轴承内外圈之间的空腔的1/2、2/3处。
2. Ensure good lubrication of garage door motor during operation. Generally speaking, when the garage door motor runs every 5000 hours or so, it is necessary to supplement or replace the grease. If it is found that the bearings are overheated or lubricated, it is necessary to change the grease or hydraulic pressure in time. When replacing grease, the old grease should be removed first, and the oil grooves of bearing and bearing cover should be washed with gasoline, then the grease should be filled in 1/2 and 2/3 of the cavity between the inner and outer rings of the bearing.
3、一旦发现车库门电机运行的振动及噪声明显增大时，就说明电机轴承的寿命已到达极限，这时需要检查轴承的径向游隙是否达到相关数值，并及时更换新的电机轴承。
3. Once it is found that the vibration and noise of the garage door motor are obviously increased, the life of the motor bearing has reached the limit. siwang.75ix.cn    hansi.75ix.cn    buxiugangsi.75ix.cn

4、当车库门电机的热保护连续发生振动时，必须要先查明故障来自哪个方向，看电机还是超负荷或保护装置整定值太低的问题，待故障消除后，才能投入正常运行中。
4. When the thermal protection of garage door motor continuously vibrates, we must first find out which direction the fault comes from, and see whether the motor is overloaded or the setting value of the protection device is too low. Only after the fault is eliminated, can it be put into normal operation.
