產品介紹

液(ye)壓(ya)(ya)電(dian)梯是指通過(guo)液(ye)壓(ya)(ya)動(dong)(dong)(dong)力源，把油壓(ya)(ya)入(ru)油缸使(shi)柱塞作(zuo)直(zhi)線(xian)運(yun)動(dong)(dong)(dong)，直(zhi)接或(huo)通過(guo)鋼絲繩間接地使(shi)轎(jiao)廂運(yun)動(dong)(dong)(dong)的(de)電(dian)梯。液(ye)壓(ya)(ya)電(dian)梯是機、電(dian)、電(dian)子(zi)、液(ye)壓(ya)(ya)產品，由下列相對(dui)獨立但又相互聯系配合的(de)系統(tong)組(zu)成：泵站系統(tong)、液(ye)壓(ya)(ya)系統(tong)、導向系統(tong)、轎(jiao)廂、門系統(tong)、電(dian)氣控(kong)制系統(tong)、保護系統(tong)等。

濟(ji)(ji)南別墅電梯(ti)(ti)技術(shu)人員講解(jie)(jie)一(yi)(yi)下(xia)：液(ye)壓(ya)驅(qu)動(dong)是較早出(chu)現的(de)一(yi)(yi)種電梯(ti)(ti)驅(qu)動(dong)方(fang)式。早期的(de)液(ye)壓(ya)電梯(ti)(ti)的(de)傳動(dong)介質是水(shui)，利(li)用(yong)(yong)水(shui)的(de)不可(ke)壓(ya)縮特性通過加壓(ya)提高水(shui)的(de)壓(ya)力，將帶(dai)有(you)一(yi)(yi)壓(ya)力的(de)水(shui)接入缸(gang)體(ti)內(nei)，推動(dong)缸(gang)體(ti)內(nei)的(de)柱塞頂升轎廂(xiang)(xiang)，使轎廂(xiang)(xiang)向上運(yun)行(xing)；通過泄流閥開啟泄流，轎廂(xiang)(xiang)在(zai)自重的(de)作用(yong)(yong)下(xia)下(xia)降。但由(you)于(yu)水(shui)壓(ya)含有(you)氣泡會產生波動(dong)及(ji)缸(gang)體(ti)生銹(xiu)問題難以(yi)解(jie)(jie)決，之后就用(yong)(yong)油為(wei)(wei)媒介驅(qu)動(dong)柱塞做直線運(yun)動(dong)。由(you)于(yu)液(ye)壓(ya)電梯(ti)(ti)提升力大、可(ke)以(yi)提供(gong)較高的(de)機械效率且能(neng)耗較低，因此對于(yu)短行(xing)程、重載荷(he)的(de)場合，使用(yong)(yong)優點(dian)尤為(wei)(wei)明顯。另外，因為(wei)(wei)液(ye)壓(ya)電梯(ti)(ti)不必在(zai)樓頂設置(zhi)機房(fang)，減小了井道豎向尺寸(cun)，有(you)效地利(li)用(yong)(yong)了建筑物空間，所以(yi)液(ye)壓(ya)電梯(ti)(ti)應用(yong)(yong)前景(jing)較為(wei)(wei)寬廣(guang)(guang)。如今(jin)液(ye)壓(ya)電梯(ti)(ti)廣(guang)(guang)泛(fan)用(yong)(yong)于(yu)停車(che)場、工廠及(ji)低層的(de)建筑中。對于(yu)負載大、速度慢及(ji)行(xing)程短的(de)場合，選(xuan)用(yong)(yong)液(ye)壓(ya)電梯(ti)(ti)比(bi)曳電梯(ti)(ti)更(geng)經濟(ji)(ji)、更(geng)適宜(yi)。

液(ye)(ye)(ye)壓電(dian)梯(ti)(ti)運(yun)行(xing)(xing)分上行(xing)(xing)和下行(xing)(xing)。電(dian)梯(ti)(ti)下行(xing)(xing)時(shi)，打(da)開(kai)閥組(zu)，利用轎廂自重(zhong)[客（貨）的(de)重(zhong)量(liang)]造成的(de)壓差，使液(ye)(ye)(ye)壓油回(hui)流(liu)液(ye)(ye)(ye)壓油箱中(zhong)(zhong)，實現電(dian)梯(ti)(ti)的(de)下行(xing)(xing)運(yun)動，此時(shi)液(ye)(ye)(ye)壓泵站不消(xiao)耗功，轎廂下行(xing)(xing)的(de)速(su)度是由液(ye)(ye)(ye)壓系統中(zhong)(zhong)閥組(zu)開(kai)啟的(de)大小來控制的(de)。

電(dian)(dian)梯(ti)上行時(shi)，由液(ye)壓泵(beng)站提(ti)供電(dian)(dian)梯(ti)上行所需的動力壓差，液(ye)壓系統中的閥組控制泵(beng)中液(ye)壓油的流量，當液(ye)壓油進入缸內油腔中，液(ye)壓油推動液(ye)壓油缸中柱塞(sai)來(lai)提(ti)升轎廂，從(cong)而實現電(dian)(dian)梯(ti)的上行運動，此時(shi)液(ye)壓泵(beng)消耗的功(gong)為實際功(gong)。
