具體參數
隨著現(xian)代工(gong)(gong)業的(de)(de)(de)興起,以混(hun)凝(ning)土(tu)為主(zhu)材料的(de)(de)(de)建(jian)設方式已經(jing)成為了建(jian)筑業施工(gong)(gong)的(de)(de)(de)主(zhu)要構(gou)造(zao)之(zhi)一,在各(ge)種工(gong)(gong)程施工(gong)(gong)建(jian)設中占據了很大的(de)(de)(de)比例,使得混(hun)凝(ning)土(tu)機械(xie)的(de)(de)(de)發展經(jing)久不衰,且(qie)有越演越烈的(de)(de)(de)形勢。拖式混(hun)凝(ning)土(tu)泵,簡稱拖泵,是各(ge)種混(hun)凝(ning)土(tu)機械(xie)中的(de)(de)(de)一種,用于(yu)混(hun)凝(ning)土(tu)施工(gong)(gong)中的(de)(de)(de)輸送和澆注(zhu)工(gong)(gong)作。
拖泵(beng)分類選型
37千(qian)(qian)瓦(wa)(wa)(目前國內標(biao)準混凝土泵(beng),37千(qian)(qian)瓦(wa)(wa)以下為細石(shi)砂漿泵(beng))、45千(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)瓦(wa)(wa)(柴(chai)油)、132千(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)瓦(wa)(wa)(柴(chai)油)、174千(qian)(qian)瓦(wa)(wa)(柴(chai)油)等。
選擇多(duo)大電機(ji)(ji)混凝(ning)土(tu)泵(beng),首先要考(kao)慮變壓器容量,其次(ci)考(kao)慮距(ju)離混凝(ning)土(tu)泵(beng)的(de)遠近和線(xian)徑(jing)大小,以免壓降過(guo)大造(zao)成電流增高或跳(tiao)閘停(ting)機(ji)(ji),過(guo)大功(gong)率造(zao)成成本增加和使(shi)用不便(bian)。電機(ji)(ji)過(guo)小,同時也滿足不了工程需要。
混(hun)凝土輸(shu)送(song)泵功率、混(hun)凝土輸(shu)送(song)泵出口壓力、混(hun)凝土輸(shu)送(song)泵輸(shu)送(song)量之間的關系
一臺混凝土(tu)輸(shu)送(song)泵的(de)電(dian)機功(gong)率(lv)(lv)是(shi)決定出(chu)口壓(ya)力(li)和輸(shu)送(song)方量(liang)(liang)的(de)前(qian)提條件,在電(dian)機功(gong)率(lv)(lv)一定的(de)情況下,壓(ya)力(li)的(de)升高必將(jiang)使輸(shu)送(song)量(liang)(liang)降低;相反,降低出(chu)口壓(ya)力(li),將(jiang)會使輸(shu)送(song)量(liang)(liang)增加(jia)。
為了保證混凝土輸(shu)(shu)(shu)送(song)(song)泵既要有較大(da)輸(shu)(shu)(shu)送(song)(song)量,又(you)能有一定(ding)的出口(kou)壓力(li)和與之相匹配的經(jing)濟功(gong)(gong)率(lv),在混凝土輸(shu)(shu)(shu)送(song)(song)泵的設(she)計中,大(da)都采用了恒功(gong)(gong)率(lv)柱塞泵;即恒功(gong)(gong)率(lv)值選定(ding)后,當出口(kou)壓力(li)升高時,油泵輸(shu)(shu)(shu)出排量會自動降低,達(da)到(dao)與功(gong)(gong)率(lv)設(she)計相對(dui)應的值;如(ru)果既要達(da)到(dao)出口(kou)壓力(li)高,又(you)想得到(dao)輸(shu)(shu)(shu)送(song)(song)量大(da)的目的。惟一的途徑就是增(zeng)加(jia)電(dian)機功(gong)(gong)率(lv)。
因此,在(zai)國家(jia)新標準中(zhong),引用(yong)了混凝(ning)土(tu)輸送(song)泵的(de)(de)(de)能(neng)力(li)(li)指數概念(以MPa·m3/h為度(du)量(liang)(liang)單位);即混凝(ning)土(tu)輸送(song)泵的(de)(de)(de)實(shi)際(ji)(ji)出口壓(ya)力(li)(li)與(yu)每小時實(shi)際(ji)(ji)輸送(song)量(liang)(liang)之乘積,該(gai)值(zhi)越大,其(qi)能(neng)力(li)(li)指數也(ye)越大,電機的(de)(de)(de)功(gong)(gong)率(lv)也(ye)將越大,由此實(shi)現大排量(liang)(liang)、高(gao)揚程的(de)(de)(de)目的(de)(de)(de)。科尼樂公司在(zai)設(she)計時,還(huan)采用(yong)了高(gao)低壓(ya)切換的(de)(de)(de)功(gong)(gong)能(neng)設(she)計,以滿(man)足不同(tong)的(de)(de)(de)施工要求,在(zai)經濟狀(zhuang)態下,又能(neng)產(chan)生(sheng)較(jiao)大的(de)(de)(de)輸送(song)量(liang)(liang),或者以相同(tong)的(de)(de)(de)電機功(gong)(gong)率(lv),產(chan)生(sheng)較(jiao)高(gao)的(de)(de)(de)出口壓(ya)力(li)(li)。
