三明有效降低電梯的能耗的方法
電梯是一種在日常的使用過程之中實用的設備,耗能也是比較多的,那么我們應該采取怎樣的措施來降低電梯的能耗呢?
1.選(xuan)擇減小電梯機(ji)械(xie)系(xi)統的慣性和磨擦阻(zu)力。
2.電(dian)梯安裝合理(li)運用對重和平衡重。驅動系統使用永(yong)磁(ci)同(tong)步無齒輪曳引機從永(yong)磁(ci)同(tong)步馬達(da)(da)工作原理(li)可(ke)知其勵(li)磁(ci)是由永(yong)磁(ci)鐵來實現的,不需要定子額外提供(gong)勵(li)磁(ci)電(dian)流,因而電(dian)機的功率(lv)因數,可(ke)以(yi)達(da)(da)高。
3.同時永磁(ci)同步(bu)馬達的轉(zhuan)(zhuan)子無電流通(tong)過(guo),電梯(ti)安(an)裝不存在(zai)轉(zhuan)(zhuan)子耗(hao)損問(wen)題,一般比異(yi)步(bu)電機降低(di)耗(hao)損。由于沒率低(di),高能(neng)耗(hao)蝸輪蝸桿傳動副,能(neng)耗(hao)進一步(bu)降低(di)。在(zai)停站較少(shao)的群梯(ti)布置中(zhong),一個主機驅(qu)動兩個轎(jiao)廂分別上下運(yun)行是一種節能(neng)的方(fang)案(an)。
4.減少能耗的另一途徑是電梯運(yun)行(xing)(xing)過(guo)程的(de)能耗控制(zhi)。利用電梯空載上行(xing)(xing)、滿(man)載下(xia)行(xing)(xing)時(shi)電機處(chu)以發電狀態的(de)特性,將(jiang)能反饋給電網(wang),電梯安(an)裝將(jiang)這種節能措施(指(zhi)針對(dui)問題(ti)的(de)解決辦法)在(zai)高速(su)梯上效果較好。還(huan)有(you)一種節能方案將(jiang)在(zai)軟件(jian)控制(zhi)中得以實現(xian)。
5.電(dian)(dian)(dian)(dian)梯(ti)召喚與(yu)轎廂指令合一(yi)的(de)樓層入口乘(cheng)客(ke)登記(ji)方案是電(dian)(dian)(dian)(dian)梯(ti)控(kong)制(zhi)方式的(de)一(yi)項有效技術,使原來層站(zhan)上(shang)乘(cheng)客(ke)未知的(de)目的(de)層變(bian)得可(ke)見,從而(er)使控(kong)制(zhi)系(xi)統(tong)(tong)(tong)的(de)派梯(ti)效率(lv)達(da)高(gao)。電(dian)(dian)(dian)(dian)梯(ti)保(bao)養(yang)電(dian)(dian)(dian)(dian)氣(qi)控(kong)制(zhi)系(xi)統(tong)(tong)(tong):電(dian)(dian)(dian)(dian)氣(qi)控(kong)制(zhi)系(xi)統(tong)(tong)(tong)的(de)主(zhu)要功能是對電(dian)(dian)(dian)(dian)梯(ti)的(de)運(yun)行實行操縱(zong)和控(kong)制(zhi)。電(dian)(dian)(dian)(dian)氣(qi)控(kong)制(zhi)系(xi)統(tong)(tong)(tong)主(zhu)要由操縱(zong)裝(zhuang)置,位(wei)置顯示裝(zhuang)置,控(kong)制(zhi)屏(柜),平(ping)層裝(zhuang)置,選層器等(deng)組(zu)成。
