在进行电梯维保时，维修人员使用紧急层门钥匙打开层门，准备进入轿厢顶部之前，需要保持专注和清醒。尽管层门已经打开，但一旦进入轿厢，层门将被自动关闭系统重新锁定，以保证安全。因此，在进入轿厢内部之前，务必将轿厢内的检修开关切换到检修模式，并且按下急停按钮，以防电梯意外启动。维修人员在进入轿厢时应迅速通过，避免在层门口附近停留。同时，在轿厢顶部的检修控制盒中开启检修开关，确保电梯不会在维修过程中被误操作。"><meta name="mobile-agent" content="format=html5;url=http://m.jialilift.com/articles/dtgbjd.html"><meta name="mobile-agent" content="format=xhtml;url=http://m.jialilift.com/articles/dtgbjd.html">

    <b><span>电梯停梯维修</span></b><b></b>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    <span>当需要进行电梯轿厢的维修工作且不希望其运行时，维修人员应当按照以下步骤来切断相应的开关：</span>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    1.<span>在电梯机房内，应关闭电源总开关。</span>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    2.<span>在轿顶上，要启动安全钳的关联开关，并通过轿顶的紧急停止开关来切断电源。</span>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    3.<span>在轿厢内部，应该按下控制盒上的紧急停止按钮，并且切断电源开关。</span>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    4.<span>在电梯井道底部（底坑），须确保限速器张紧装置的安全开关已经激活，以及底坑检修盒中的紧急停止开关已被切断。</span>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    <span>这些措施都是为了保证维修工作的安全进行，防止电梯在不当的时候突然运行造成意外。</span>
</p>
<p class="MsoNormal">
    <b><span>机械制动器的维修</span></b><b></b>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    <span>定期检查弹性联轴器的弹性损耗和老化状况。如果出现这些问题，应立即替换，以防止在运行中产生撞击声、电梯厢体的震动和噪音。</span>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    <span>制动器的操作应该灵活且可靠，电磁铁在铜衬套中的运动应顺畅无阻。如果出现动作迟缓的情况，须及时进行维修，并清理铜衬套中的油渍，可以适量添加滑石粉作为润滑材料。所有销轴部位，应经常涂抹机油以保持润滑。若发现有油泥堆积，应将其拆卸并清洁。确保制动效能稳定，同时清除溅到制动轮上的任何油渍。</span>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    <span>制动器线圈的温升通常不应超过</span>60<span>摄氏度，最高温度不允许超过</span><span>105</span><span>摄氏度。要经常检查线圈接头是否有松动现象，并确保其绝缘性能良好。</span>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    <span>制动器在工作时，刹车片应紧密而均匀地贴合在制动轮的工作表面上；松开刹车时，刹车片与制动轮之间的间隙应保持在</span>0.5<span>至</span><span>0.7</span><span>毫米之间，而且两个刹车片应保持相同。如果该间隙过大，可能会导致制动减速度增加，从而影响舒适性，因此需要定期调整这个间隙。特别是在使用一段时间后，刹车片和制动轮的摩擦表面会变得更加平滑。这时，在松开刹车后，可以将间隙调整到不产生摩擦的最小值，这样可以明显提升乘坐的舒适度。</span>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    <span>当固定制动带的钉子突出时，应立即更换，以防止它们与制动轮发生摩擦。如果发现制动力减弱，可以通过调整弹簧的螺母来增强制动力。假如观察到刹车片和制动轮的同心度不足，那么应当立刻调整制动器底座底部的垫片。</span>
</p>
<p class="MsoNormal">
    <b><span>控制柜的维修</span></b><b></b>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    电梯维保<span>需要定期对接触器和继电器进行检查，清理吸附在接触面的灰尘和油污。确保触点连接稳定，检查线圈的绝缘性能，联锁机构的动作是否准确，以及在继电器和接触器动作时是否有异常声音。检查动触点连接的导线是否有断股情况。确保接线柱上的导线连接牢固无松动。在更换保险丝时，其熔断电流需与所在电路相适应。通常控制电路的保险丝额定电流应与供电额定电流相同。电动机电路的保险丝额定电流推荐为电动机额定电流的</span>2.5<span>到</span><span>3</span><span>倍。</span>
</p>
<p class="MsoNormal">
    <b><span>速度测量装置的维修</span></b><b></b>
</p>
<p class="MsoNormal" style="text-indent:21.0000pt;">
    当在电梯维保时，<span>如果电梯轿厢在垂直方向上出现抖动或在启动和制动时感受到振动，除了检查驱动系统之外，首要任务是检查测速发电机的安装是否与曳引机轴心保持一致。对于采用齿形尼龙带或三角带传动的系统，需要检查传动带的磨损或损伤情况；若存在问题，必须进行替换，并清除电机内部的碳粉。同时，需要对轴承进行润滑。如果测速发电机采用电刷，那么每季度应检查一次电刷磨损状况，如有严重磨损，须更换电刷，并清理电机内的灰尘。假如测速设备是光电编码器，需要确保光电传感器功能正常，清洁发射和接收镜面，以及检查安装位置是否发生变化等。</span>
