1.2<\/span> <\/span><\/b>升<\/span><\/b>降機(jī)的常見故障<\/span><\/b> <\/strong><\/p>

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

①保護(hù)開關(guān)Q1跳閘，保護(hù)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(shí)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(yùn)行。<\/span><\/strong><\/p>

③吊籠運(yùn)行時(shí)震動(dòng)較大；吊籠起動(dòng)或停止時(shí)有跳動(dòng)現(xiàn)象；吊籠運(yùn)行時(shí)電機(jī)跳動(dòng)；吊籠運(yùn)行時(shí)有跳動(dòng)現(xiàn)象；吊籠運(yùn)行時(shí)有擺動(dòng)現(xiàn)象；吊籠啟、制動(dòng)時(shí)振動(dòng)大；吊籠制動(dòng)時(shí)下滑距離過長(zhǎng)；吊籠上下運(yùn)行有自�，F(xiàn)象；吊籠上行或下行運(yùn)行時(shí)；限位碰鐵碰到限位開關(guān)不停止。<\/span><\/strong><\/p>

④<\/span>減速機(jī)<\/span><\/a>漏油；減速機(jī)<\/span>蝸輪<\/span><\/a>磨損快；減速機(jī)通氣塞漏油；減速機(jī)有異常的不穩(wěn)定的噪聲；減速機(jī)有異常穩(wěn)定的運(yùn)轉(zhuǎn)噪聲；減速機(jī)輸出軸不轉(zhuǎn)，但電動(dòng)機(jī)轉(zhuǎn)動(dòng)。<\/span><\/strong><\/p>
