门内电机保养和更换要点
2018-5-11 10:44:44

     电机是车库门中非常重要的部分,万一出现故障,将影响使用。下面,就让小编来给我们讲解一下门电机保养知识。
    Motor is a very important part of garage door. In case of failure, it will affect the use. Next, let Xiaobian to explain to us about the door motor maintenance knowledge.
    1、使用环境应经常保持干燥,电动机表面应保持清洁,进风口不应受尘土、纤维等阻碍。
    the use of the environment should always be kept dry, motor surface should be kept clean, air inlet should not be impeded by dust, fiber and so on.
    2、应保证电动机在运行过程中良好的润滑。一般的电动机运行5000小时左右,即应补充或更换润滑脂,运行中发现轴承过热或润滑变质时,液压及时换润滑脂。更换润滑脂时,应清除旧的润滑油,并有汽油洗净轴承及轴承盖的油槽。
    ensure that the motor is well lubricated during operation. General motor running for about 5000 hours, that is, should be supplemented or replaced grease, running during the discovery of overheating or lubrication deterioration, the hydraulic timely change grease. When replacing grease, the old lubricating oil should be removed, and the oil groove of bearing and bearing cover should be washed with gasoline.

    3、更换绕组时必须记下原绕组的形式,尺寸及匝数,线规等,当失落了这些数据时,应向制造厂索取,随意更改原设计绕组,常常使电动机某项或几项性能恶化,甚至于无法使用。
    when changing the winding, we must remember the form of the original winding, the size and the number of turns, the line gauge and so on. When the data is lost, it should be asked to the manufacturer and change the original design windings at will, which often worsens the performance of some or several items of the motor, or even can not be used.
    4、当轴承的寿命终了时,电动机运行的振动及噪声将明显增大,检查轴承的径向游隙达到下列值时,即应更换轴承。
    when the life of the bearing ends, the vibration and noise of the motor will increase obviously. When the radial clearance of the bearing is checked to the following value, the bearing should be replaced.
    5、拆卸电动机时,从轴伸端或非伸端取出转子都可以。如果没有必要卸下风扇,还是从非轴伸端取出转子较为便利,从定子中抽出转子时,应防止损坏定子绕组或绝缘。
    when removing the motor, it is OK to remove the rotor from the shaft extension or the non extension end. If it is not necessary to unload the fan or remove the rotor from the non axial extension end, it is more convenient to remove the rotor from the stator, so the stator winding or insulation should be prevented.
    6、当电动机的热保护连续发生动作时,应查明故障来自电动机还是超负荷或保护装置整定值太低,消除故障后,方可投入运行。
    when the thermal protection of the motor continues to occur, it should be found that the fault comes from the motor or the overload or protection device is too low. After the failure, it can be put into operation.
    如果电机万一出现损坏,不得不更换,该如何更换呢?
    If the motor has to be replaced in case of damage, how should it be replaced?
    将新电机按照上面相反的顺序安装好。
    Install the new motor in the reverse order.
    将环形手拉链条垂直向下,以免发生卡阻现象。
    The annular hand zipper strip is vertically downward to avoid the phenomenon of blockage.
    将电机做好标记后拆除。
    The motor is marked and dismantled.
    松动电机地脚螺丝,将传动链条摘下。
    Loosen the motor foundation screw and remove the transmission chain.
    拆除电机地脚螺丝,取下电机。
    Remove the motor anchor screw and remove the motor.
