產品介紹

液(ye)(ye)(ye)壓電梯是指(zhi)通過液(ye)(ye)(ye)壓動(dong)力源，把油壓入(ru)油缸使柱塞作直線運(yun)動(dong)，直接(jie)(jie)或通過鋼(gang)絲(si)繩間(jian)接(jie)(jie)地使轎廂運(yun)動(dong)的電梯。液(ye)(ye)(ye)壓電梯是機(ji)、電、電子、液(ye)(ye)(ye)壓產品(pin)，由下(xia)列相(xiang)(xiang)對獨立但又相(xiang)(xiang)互聯系(xi)配合的系(xi)統(tong)(tong)(tong)組成：泵站系(xi)統(tong)(tong)(tong)、液(ye)(ye)(ye)壓系(xi)統(tong)(tong)(tong)、導向系(xi)統(tong)(tong)(tong)、轎廂、門系(xi)統(tong)(tong)(tong)、電氣控(kong)制系(xi)統(tong)(tong)(tong)、保護系(xi)統(tong)(tong)(tong)等。

濟(ji)南別(bie)墅(shu)電(dian)(dian)梯(ti)(ti)(ti)(ti)技(ji)術人員講(jiang)解一(yi)下(xia)(xia)：液(ye)(ye)(ye)壓(ya)(ya)驅(qu)動是較(jiao)早出現的(de)(de)(de)(de)(de)一(yi)種電(dian)(dian)梯(ti)(ti)(ti)(ti)驅(qu)動方式。早期的(de)(de)(de)(de)(de)液(ye)(ye)(ye)壓(ya)(ya)電(dian)(dian)梯(ti)(ti)(ti)(ti)的(de)(de)(de)(de)(de)傳動介(jie)質是水，利(li)用(yong)(yong)水的(de)(de)(de)(de)(de)不可(ke)壓(ya)(ya)縮特性通過加壓(ya)(ya)提高(gao)水的(de)(de)(de)(de)(de)壓(ya)(ya)力(li)，將帶有(you)一(yi)壓(ya)(ya)力(li)的(de)(de)(de)(de)(de)水接入缸體(ti)內，推動缸體(ti)內的(de)(de)(de)(de)(de)柱塞頂升轎廂(xiang)，使轎廂(xiang)向上運行(xing)；通過泄流閥(fa)開啟泄流，轎廂(xiang)在(zai)(zai)自重的(de)(de)(de)(de)(de)作用(yong)(yong)下(xia)(xia)下(xia)(xia)降。但由于(yu)水壓(ya)(ya)含有(you)氣泡會產生波動及(ji)缸體(ti)生銹問題(ti)難以解決，之后(hou)就用(yong)(yong)油為(wei)(wei)媒介(jie)驅(qu)動柱塞做(zuo)直線運動。由于(yu)液(ye)(ye)(ye)壓(ya)(ya)電(dian)(dian)梯(ti)(ti)(ti)(ti)提升力(li)大、可(ke)以提供較(jiao)高(gao)的(de)(de)(de)(de)(de)機械(xie)效(xiao)率且能耗(hao)較(jiao)低(di)，因此對于(yu)短(duan)行(xing)程、重載(zai)荷的(de)(de)(de)(de)(de)場(chang)(chang)合，使用(yong)(yong)優點尤(you)為(wei)(wei)明(ming)顯。另(ling)外，因為(wei)(wei)液(ye)(ye)(ye)壓(ya)(ya)電(dian)(dian)梯(ti)(ti)(ti)(ti)不必在(zai)(zai)樓頂設置機房(fang)，減(jian)小了井道豎向尺寸，有(you)效(xiao)地(di)利(li)用(yong)(yong)了建筑物空間，所以液(ye)(ye)(ye)壓(ya)(ya)電(dian)(dian)梯(ti)(ti)(ti)(ti)應(ying)用(yong)(yong)前景(jing)較(jiao)為(wei)(wei)寬廣。如今液(ye)(ye)(ye)壓(ya)(ya)電(dian)(dian)梯(ti)(ti)(ti)(ti)廣泛用(yong)(yong)于(yu)停(ting)車場(chang)(chang)、工廠及(ji)低(di)層的(de)(de)(de)(de)(de)建筑中(zhong)。對于(yu)負(fu)載(zai)大、速度慢及(ji)行(xing)程短(duan)的(de)(de)(de)(de)(de)場(chang)(chang)合，選(xuan)用(yong)(yong)液(ye)(ye)(ye)壓(ya)(ya)電(dian)(dian)梯(ti)(ti)(ti)(ti)比曳電(dian)(dian)梯(ti)(ti)(ti)(ti)更經濟(ji)、更適宜。

液壓(ya)電(dian)梯運行(xing)分上行(xing)和下(xia)行(xing)。電(dian)梯下(xia)行(xing)時，打開(kai)閥組，利用轎廂自重[客（貨）的(de)重量]造成(cheng)的(de)壓(ya)差，使液壓(ya)油回流液壓(ya)油箱中，實現(xian)電(dian)梯的(de)下(xia)行(xing)運動，此時液壓(ya)泵站不消耗(hao)功，轎廂下(xia)行(xing)的(de)速度是由液壓(ya)系統中閥組開(kai)啟的(de)大小來控制的(de)。

電梯上(shang)行(xing)時，由液(ye)(ye)(ye)壓泵站(zhan)提(ti)供電梯上(shang)行(xing)所(suo)需的動力壓差，液(ye)(ye)(ye)壓系統中(zhong)的閥(fa)組控制(zhi)泵中(zhong)液(ye)(ye)(ye)壓油的流量，當(dang)液(ye)(ye)(ye)壓油進(jin)入缸內油腔中(zhong)，液(ye)(ye)(ye)壓油推動液(ye)(ye)(ye)壓油缸中(zhong)柱塞(sai)來(lai)提(ti)升轎廂，從而實現電梯的上(shang)行(xing)運(yun)動，此時液(ye)(ye)(ye)壓泵消(xiao)耗的功為實際功。
