具體參數
隨著現(xian)代工(gong)業(ye)的興起,以混(hun)凝(ning)土(tu)(tu)為主(zhu)材料(liao)的建設方式已經(jing)成為了(le)建筑業(ye)施(shi)工(gong)的主(zhu)要構(gou)造之一,在各種(zhong)工(gong)程(cheng)施(shi)工(gong)建設中(zhong)占據了(le)很大的比(bi)例,使(shi)得混(hun)凝(ning)土(tu)(tu)機(ji)械的發展經(jing)久不衰,且有越(yue)演(yan)越(yue)烈的形勢。拖式混(hun)凝(ning)土(tu)(tu)泵,簡稱拖泵,是各種(zhong)混(hun)凝(ning)土(tu)(tu)機(ji)械中(zhong)的一種(zhong),用(yong)于混(hun)凝(ning)土(tu)(tu)施(shi)工(gong)中(zhong)的輸送(song)和澆注工(gong)作。
拖泵分類選型
37千(qian)(qian)(qian)瓦(wa)(目前國內標準(zhun)混凝(ning)土泵,37千(qian)(qian)(qian)瓦(wa)以下為細(xi)石砂漿泵)、45千(qian)(qian)(qian)瓦(wa)、55千(qian)(qian)(qian)瓦(wa)、75千(qian)(qian)(qian)瓦(wa)、90千(qian)(qian)(qian)瓦(wa)、110千(qian)(qian)(qian)瓦(wa)、130千(qian)(qian)(qian)瓦(wa)(柴(chai)(chai)油(you)(you))、132千(qian)(qian)(qian)瓦(wa)、162千(qian)(qian)(qian)瓦(wa)(柴(chai)(chai)油(you)(you))、174千(qian)(qian)(qian)瓦(wa)(柴(chai)(chai)油(you)(you))等。
選(xuan)擇多大電機混凝土泵(beng),首先(xian)要(yao)考慮變壓(ya)(ya)器容量(liang),其(qi)次考慮距離混凝土泵(beng)的遠近和線徑大小(xiao),以免壓(ya)(ya)降過(guo)大造成(cheng)電流(liu)增(zeng)(zeng)高(gao)或跳閘停機,過(guo)大功率造成(cheng)成(cheng)本增(zeng)(zeng)加和使用不便。電機過(guo)小(xiao),同(tong)時也滿足(zu)不了工程需要(yao)。
混(hun)(hun)凝(ning)土輸(shu)(shu)送(song)泵功率、混(hun)(hun)凝(ning)土輸(shu)(shu)送(song)泵出口壓力(li)、混(hun)(hun)凝(ning)土輸(shu)(shu)送(song)泵輸(shu)(shu)送(song)量之(zhi)間的關(guan)系
一(yi)臺混凝(ning)土輸(shu)(shu)送(song)泵(beng)的電機功率是決定(ding)出(chu)口(kou)壓力(li)和輸(shu)(shu)送(song)方量(liang)的前提(ti)條件(jian),在電機功率一(yi)定(ding)的情況下,壓力(li)的升高(gao)必將(jiang)使(shi)輸(shu)(shu)送(song)量(liang)降低(di);相反,降低(di)出(chu)口(kou)壓力(li),將(jiang)會使(shi)輸(shu)(shu)送(song)量(liang)增加。
為了保證混凝土(tu)輸送(song)泵(beng)既(ji)要有較大(da)(da)輸送(song)量,又能有一定的(de)(de)(de)出(chu)口壓力(li)和(he)與之相(xiang)匹(pi)配的(de)(de)(de)經濟功率(lv),在(zai)混凝土(tu)輸送(song)泵(beng)的(de)(de)(de)設計中(zhong),大(da)(da)都采(cai)用了恒(heng)功率(lv)柱塞泵(beng);即(ji)恒(heng)功率(lv)值選定后,當出(chu)口壓力(li)升(sheng)高時,油泵(beng)輸出(chu)排量會(hui)自動(dong)降(jiang)低,達到與功率(lv)設計相(xiang)對應的(de)(de)(de)值;如(ru)果(guo)既(ji)要達到出(chu)口壓力(li)高,又想得到輸送(song)量大(da)(da)的(de)(de)(de)目的(de)(de)(de)。惟一的(de)(de)(de)途徑就(jiu)是增加電(dian)機功率(lv)。
因此,在(zai)(zai)國(guo)家新標準(zhun)中(zhong),引用了混(hun)凝(ning)(ning)土輸送(song)泵的(de)(de)能(neng)(neng)力(li)指數概念(nian)(以(yi)MPa·m3/h為度量(liang)(liang)單位(wei));即(ji)混(hun)凝(ning)(ning)土輸送(song)泵的(de)(de)實(shi)際出口(kou)壓力(li)與每小時實(shi)際輸送(song)量(liang)(liang)之乘積,該值(zhi)越大(da)(da),其能(neng)(neng)力(li)指數也(ye)越大(da)(da),電(dian)機(ji)的(de)(de)功(gong)(gong)率也(ye)將(jiang)越大(da)(da),由(you)此實(shi)現大(da)(da)排量(liang)(liang)、高(gao)(gao)揚程的(de)(de)目的(de)(de)。科尼樂公司在(zai)(zai)設計(ji)時,還采用了高(gao)(gao)低壓切換的(de)(de)功(gong)(gong)能(neng)(neng)設計(ji),以(yi)滿足不同(tong)的(de)(de)施工要(yao)求,在(zai)(zai)經濟狀態下(xia),又能(neng)(neng)產(chan)(chan)生較大(da)(da)的(de)(de)輸送(song)量(liang)(liang),或者(zhe)以(yi)相同(tong)的(de)(de)電(dian)機(ji)功(gong)(gong)率,產(chan)(chan)生較高(gao)(gao)的(de)(de)出口(kou)壓力(li)。
