1.2<\/span> <\/span><\/b>升<\/span><\/b>降機的常見故障<\/span><\/b> <\/strong><\/p>

在建筑升降機運行的過程中，會出現(xiàn)眾多的問題，給施工人員帶來很多困擾。下面是對升降機一些常見故障的總結(jié)。<\/span><\/strong><\/p>

①保護開關(guān)Q1跳閘，保護開關(guān)F1、F2、F3跳閘。<\/span><\/strong><\/p>

②電源正常，電源<\/span>接觸器<\/span><\/a>不吸合；操作開關(guān)手柄置于上下行位置，接觸器不吸合；接觸器釋放有延時現(xiàn)象。接觸器易燒損；總接觸器吸合，變頻器無電，吊籠不能運行。<\/span><\/strong><\/p>

③吊籠運行時震動較大；吊籠起動或停止時有跳動現(xiàn)象；吊籠運行時電機跳動；吊籠運行時有跳動現(xiàn)象；吊籠運行時有擺動現(xiàn)象；吊籠啟、制動時振動大；吊籠制動時下滑距離過長；吊籠上下運行有自停現(xiàn)象；吊籠上行或下行運行時；限位碰鐵碰到限位開關(guān)不停止。<\/span><\/strong><\/p>

④<\/span>減速機<\/span><\/a>漏油；減速機<\/span>蝸輪<\/span><\/a>磨損快；減速機通氣塞漏油；減速機有異常的不穩(wěn)定的噪聲；減速機有異常穩(wěn)定的運轉(zhuǎn)噪聲；減速機輸出軸不轉(zhuǎn)，但電動機轉(zhuǎn)動。<\/span><\/strong><\/p>
