低凈空手拉葫蘆專為有限的空間尺寸設(shè)計(jì),大大縮短了手拉葫蘆下吊鉤到橫梁之間的距離,較低的凈空尺寸為140mm,擴(kuò)大了有效提升空間,具有較低的凈空尺寸。低凈空手拉葫蘆適用于單軌運(yùn)行,特別適用于在較低的建筑物、臨時(shí)搭建的廠房內(nèi)或起升空間有限的場所。
低凈空手拉葫蘆較小型號為1T/3M,較大型號為10T/3M,鏈條可根據(jù)起升高度的要求定做,工字鋼尺寸也可根據(jù)客戶的需要定做。
低凈空手拉葫蘆通過特定的設(shè)計(jì)能使重物升至距離固定處較近,較大程度上縮小距離,實(shí)現(xiàn)單軌小車與手拉葫蘆的低凈空空組合。除此之外,低凈空凈空手拉葫蘆還具有自重輕,手拉力小,經(jīng)濟(jì)實(shí)用等優(yōu)點(diǎn)。

鋼絲繩電動葫蘆應(yīng)用廣泛,它的電機(jī)結(jié)構(gòu)很復(fù)雜也很重要,所以電機(jī)保護(hù)器的性能關(guān)系到鋼絲繩電動葫蘆的產(chǎn)品質(zhì)量。 目前鋼絲繩電動葫蘆的電機(jī)保護(hù)器全部是智能的,可直接顯示電機(jī)的各種數(shù)據(jù),并且功能多,調(diào)試方便,既延長電機(jī)的使用壽命,又有利于解決電機(jī)意外故障的處理時(shí)間。 一個(gè)好的電機(jī)保護(hù)器不僅技術(shù)要**,較重要的是滿足市場和現(xiàn)場實(shí)際的需求,同時(shí)電機(jī)保護(hù)器的種類繁多,合理得選擇保護(hù)器的種類和功能也很重要,還要考
? 1、單相運(yùn)行,電動葫蘆電動機(jī)在運(yùn)轉(zhuǎn)過程中定子三相繞組中有一相斷開,這是常見的單相運(yùn)轉(zhuǎn)故障。此時(shí)電動機(jī)轉(zhuǎn)矩顯著減小,不出力,轉(zhuǎn)速變慢,且有“嗡嗡”異常聲。由于單相運(yùn)轉(zhuǎn)時(shí)電流很大,運(yùn)轉(zhuǎn)時(shí)間稍長會使電動機(jī)發(fā)熱嚴(yán)重而燒壞。 對于多支路并聯(lián)的電動機(jī),如其中有一路斷開時(shí),就可以用電橋測量三相繞組的電阻,如三相電阻值相差大于5%時(shí),電阻較大的一相即為斷路相。 2、電動機(jī)運(yùn)轉(zhuǎn)不久就冒煙,通常是定子三
? 電動葫蘆是起重行業(yè)重要的組成部分,安裝電動葫蘆也需要一定的技巧,那么應(yīng)該注意什么呢? 1、安裝環(huán)鏈電動葫蘆一定要先安裝好鏈盒。 2、在連接電源線時(shí),務(wù)必先提前切斷電源,同時(shí)地線應(yīng)良好接地,否則操作者觸摸葫蘆或鏈條的任何部位時(shí),都可能會感到有電擊的感覺。 3、及時(shí)有效地潤滑負(fù)載鏈,才能保證鏈條的有效使用壽命,因?yàn)殒湕l的潤滑程度是影響負(fù)載鏈?zhǔn)褂脡勖囊粋€(gè)重要因素。 4、認(rèn)真檢查鏈條的排列
鋼絲繩電動葫蘆使用頻繁偶爾會遇到升降失靈的故障,造成這個(gè)問題的原因是什么? 1、電動葫蘆控制按鈕失效。按鈕絕緣擊穿短路只要是由于頻繁操作,使其有效絕緣遭到破壞。主要原因是因?yàn)楣ぷ鳝h(huán)境惡劣造成的泄漏電流大,維修不及時(shí)等。因此除了選取質(zhì)量合格的電動葫蘆產(chǎn)品外,還要加強(qiáng)日常維護(hù),及時(shí)解決事故隱患。 2、交流接觸器主觸頭燒結(jié)鏈接。由于接觸器的質(zhì)量問題或選型不當(dāng)?shù)?,主觸頭常常燒結(jié)粘連,該斷開的時(shí)候不能斷開
