车库门在使用中不正常抖动的原因

发布人:http://www.kdjlm.com    发布时间:2021-07-13 15:38:28

电机是车库门的驱动器,它如果闹了情绪,不好好干活,您就只能干着急,没办法,给您的企业带来一些不必要的损失,
The motor is the driver of the garage door. If it is in a bad mood and doesn't work well, you can only work in a hurry, and it will bring some unnecessary losses to your enterprise,
1、定、转子之间气隙很小,容易导致定、转子之间相碰;如发现快速快速堆积门轴承磨损应及时更换,对端盖进行更换或刷镀处理,比较简单的处理方法是给端盖镶套。
1. The air gap between the stator and rotor is very small, which easily leads to the collision between the stator and rotor; If it is found that the bearing of the quick accumulation door is worn, it should be replaced in time. The end cover should be replaced or brush plated. The relatively simple treatment method is to insert a sleeve into the end cover.

2、不正常振动或噪音容易引起电机的发热,这种情况属于电机本身引起的振动,多数是由于转子动平衡不好,以及轴承不良、转轴弯曲,端盖、机座、转子不同轴心,紧固件松动或电机安装地基不平、安装不到位造成的,也可能是机械端传递过来
2. Abnormal vibration or noise is easy to cause motor heating, which belongs to the vibration caused by the motor itself, most of which are caused by poor dynamic balance of the rotor, poor bearing, bending of the shaft, different shaft axes of the end cover, base and rotor, loose fasteners or uneven foundation and improper installation of the motor, or the mechanical end
3、轴承工作不正常,应在运行3,000小时~5,000小时左右换一次润滑脂。
3. If the bearing does not work normally, the grease should be changed once after 3000-5000 hours of operation.
4、电源电压偏高,励磁电流增 大,电机会过度发热,当三相电压不对称时,即一相电压偏高或偏低时,会导致某相电流过大,电机发热,同时转距减小会发出“嗡嗡”声,时间长了会损坏绕组。机电源电压不允许超过额定值的±10%,三相电源电压之间的差值不应超出额定值的±5%。
4. When the power supply voltage is too high and the excitation current increases, the motor will overheat. When the three-phase voltage is asymmetric, that is, when the voltage of one phase is too high or too low, the motor will overheat due to the excessive current of one phase. At the same time, when the torque decreases, the motor will emit a "buzz" sound, and the winding will be damaged after a long time. The power supply voltage of the generator shall not exceed ± 10% of the rated value, and the difference between the three-phase power supply voltages shall not exceed ± 5% of the rated value.
所以,在选电机这事上,不可掉以轻心,常见的质量较好的品牌有:SEJ快速门电机,SEW,格兰德,佰阔杰等,这样就能有用避免快速快速堆积门的不正常震动了。
Therefore, in the selection of motor matter, can not be taken lightly, common good quality brands are: sej fast door motor, sew, grand, baikuojie, etc., so that it can be useful to avoid the abnormal vibration of fast stacking door.
