平衡補償鏈有哪些結構？該如何選擇？

1、穿繩補(bu)償鏈(lian)導(dao)向圈，是最原始(shi)的(de)一(yi)種補(bu)償鏈(lian)，只能用(yong)于(yu)梯速1.75m/s以下的(de)電(dian)梯。結構為在鐵鏈(lian)中(zhong)穿入(ru)麻繩，這(zhe)種補(bu)償鏈(lian)在使用(yong)過程中(zhong)由于(yu)鏈(lian)與鏈(lian)之間發生摩(mo)擦和碰(peng)撞，噪(zao)音比較(jiao)大，而且人在轎廂內有明顯的(de)抖動感。優點是價格便宜，目前大多(duo)數(shu)電(dian)梯公(gong)司已(yi)經(jing)棄用(yong)。

2、包(bao)塑補(bu)償鏈(lian)(lian)導(dao)向圈，為了減小穿(chuan)(chuan)繩(sheng)(sheng)補(bu)償鏈(lian)(lian)在運行(xing)過程(cheng)中的噪(zao)音(yin)，同時減緩環境對鐵鏈(lian)(lian)的腐蝕，于是(shi)在穿(chuan)(chuan)繩(sheng)(sheng)補(bu)償鏈(lian)(lian)的基礎上包(bao)裹(guo)一層PVC軟管，形成了包(bao)塑補(bu)償鏈(lian)(lian)。相比于穿(chuan)(chuan)繩(sheng)(sheng)補(bu)償鏈(lian)(lian)，包(bao)塑補(bu)償鏈(lian)(lian)運行(xing)時噪(zao)音(yin)大大減小，且(qie)更加美觀，但是(shi)在柔韌性及耐用(yong)性方面仍需(xu)改(gai)善。

3、全塑補償鏈導向圈，可用至6m/s的高速電梯，外表為纜狀PVC結構，使用時電梯運行能達到平穩靜音的效果，為許多大型電梯公司所喜愛。

一(yi)般(ban)來說，首先(xian)根(gen)(gen)據曳引繩的(de)(de)重(zhong)(zhong)(zhong)量(liang)減去(qu)隨(sui)行電纜(lan)的(de)(de)重(zhong)(zhong)(zhong)量(liang)以確定補(bu)償(chang)(chang)(chang)鏈(lian)(lian)(lian)的(de)(de)重(zhong)(zhong)(zhong)量(liang)，然后(hou)確定補(bu)償(chang)(chang)(chang)鏈(lian)(lian)(lian)的(de)(de)每(mei)(mei)米重(zhong)(zhong)(zhong)量(liang)，再(zai)從生產廠家的(de)(de)補(bu)償(chang)(chang)(chang)鏈(lian)(lian)(lian)的(de)(de)品種(zhong)中(zhong)選(xuan)用(yong)(yong)。專業補(bu)償(chang)(chang)(chang)鏈(lian)(lian)(lian)生產廠家一(yi)般(ban)擁(yong)有(you)靈活的(de)(de)配重(zhong)(zhong)(zhong)選(xuan)用(yong)(yong)方(fang)案。在計算補(bu)償(chang)(chang)(chang)鏈(lian)(lian)(lian)每(mei)(mei)米重(zhong)(zhong)(zhong)量(liang)里允許(xu)有(you)一(yi)定的(de)(de)誤(wu)差范圍。在誤(wu)差范圍內可(ke)有(you)兩種(zhong)選(xuan)擇，既可(ke)選(xuan)用(yong)(yong)每(mei)(mei)米重(zhong)(zhong)(zhong)量(liang)較輕的(de)(de)2根(gen)(gen)補(bu)償(chang)(chang)(chang)鏈(lian)(lian)(lian)，也可(ke)選(xuan)用(yong)(yong)每(mei)(mei)米重(zhong)(zhong)(zhong)量(liang)較重(zhong)(zhong)(zhong)的(de)(de)1根(gen)(gen)補(bu)償(chang)(chang)(chang)鏈(lian)(lian)(lian)。這(zhe)主要是考(kao)慮電梯(ti)系統中(zhong)緩(huan)(huan)沖(chong)器(qi)(qi)的(de)(de)布置情況。如果(guo)轎(jiao)廂和對(dui)重(zhong)(zhong)(zhong)下方(fang)各(ge)設一(yi)個(ge)緩(huan)(huan)沖(chong)器(qi)(qi)，或者轎(jiao)廂設有(you)2個(ge)、對(dui)重(zhong)(zhong)(zhong)側(ce)設有(you)一(yi)個(ge)，那(nei)么采(cai)用(yong)(yong)2根(gen)(gen)補(bu)償(chang)(chang)(chang)鏈(lian)(lian)(lian)較為合適；如果(guo)轎(jiao)廂及(ji)對(dui)重(zhong)(zhong)(zhong)下方(fang)各(ge)設有(you)2個(ge)緩(huan)(huan)沖(chong)器(qi)(qi)，那(nei)么就應采(cai)用(yong)(yong)1根(gen)(gen)補(bu)償(chang)(chang)(chang)鏈(lian)(lian)(lian)。
