隨著現代工(gong)(gong)業的(de)興起,以混(hun)(hun)凝(ning)(ning)土(tu)為主材料的(de)建設方(fang)式已(yi)經成為了建筑業施工(gong)(gong)的(de)主要構造之一,在各種工(gong)(gong)程施工(gong)(gong)建設中占據了很大的(de)比例(li),使得混(hun)(hun)凝(ning)(ning)土(tu)機械的(de)發展經久(jiu)不衰,且有越(yue)(yue)演(yan)越(yue)(yue)烈的(de)形勢。拖式混(hun)(hun)凝(ning)(ning)土(tu)泵,簡稱(cheng)拖泵,是各種混(hun)(hun)凝(ning)(ning)土(tu)機械中的(de)一種,用于混(hun)(hun)凝(ning)(ning)土(tu)施工(gong)(gong)中的(de)輸送和澆注(zhu)工(gong)(gong)作(zuo)。
拖泵分類選型
37千(qian)(qian)(qian)瓦(wa)(wa)(wa)(目前(qian)國內標(biao)準混凝土(tu)泵,37千(qian)(qian)(qian)瓦(wa)(wa)(wa)以(yi)下(xia)為細(xi)石砂漿泵)、45千(qian)(qian)(qian)瓦(wa)(wa)(wa)、55千(qian)(qian)(qian)瓦(wa)(wa)(wa)、75千(qian)(qian)(qian)瓦(wa)(wa)(wa)、90千(qian)(qian)(qian)瓦(wa)(wa)(wa)、110千(qian)(qian)(qian)瓦(wa)(wa)(wa)、130千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油)、132千(qian)(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油)、174千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油)等。
選擇多大電機(ji)混凝土泵,首先要(yao)考慮(lv)變壓(ya)器容(rong)量,其次考慮(lv)距離(li)混凝土泵的遠(yuan)近和(he)線徑大小,以免壓(ya)降過(guo)大造(zao)成(cheng)電流增(zeng)高或跳閘停機(ji),過(guo)大功率造(zao)成(cheng)成(cheng)本增(zeng)加和(he)使用(yong)不(bu)便。電機(ji)過(guo)小,同(tong)時也(ye)滿足不(bu)了工程需要(yao)。
混凝土(tu)輸(shu)(shu)送(song)(song)(song)泵功率、混凝土(tu)輸(shu)(shu)送(song)(song)(song)泵出口壓力、混凝土(tu)輸(shu)(shu)送(song)(song)(song)泵輸(shu)(shu)送(song)(song)(song)量之間的關系
一(yi)(yi)臺(tai)混(hun)凝(ning)土輸(shu)送(song)泵(beng)的電(dian)機功率是決定出口壓力(li)和(he)輸(shu)送(song)方(fang)量的前提(ti)條(tiao)件,在電(dian)機功率一(yi)(yi)定的情況下,壓力(li)的升高必將使輸(shu)送(song)量降低(di)(di);相反,降低(di)(di)出口壓力(li),將會(hui)使輸(shu)送(song)量增加。
為了保證混凝(ning)土輸(shu)(shu)送(song)泵既要有較大(da)輸(shu)(shu)送(song)量,又(you)能有一(yi)定的出口(kou)壓力和與(yu)之相匹配(pei)的經濟功(gong)率,在混凝(ning)土輸(shu)(shu)送(song)泵的設(she)計中,大(da)都(dou)采用了恒功(gong)率柱塞泵;即恒功(gong)率值選(xuan)定后,當(dang)出口(kou)壓力升高時(shi),油泵輸(shu)(shu)出排量會自動降(jiang)低,達到與(yu)功(gong)率設(she)計相對應的值;如果既要達到出口(kou)壓力高,又(you)想(xiang)得到輸(shu)(shu)送(song)量大(da)的目的。惟一(yi)的途徑就(jiu)是增加電機功(gong)率。
因此,在(zai)國(guo)家新(xin)標準(zhun)中,引用(yong)了(le)混(hun)凝土(tu)輸(shu)送(song)泵(beng)的(de)(de)(de)能(neng)力(li)指(zhi)數概念(以MPa·m3/h為度(du)量(liang)(liang)單位);即(ji)混(hun)凝土(tu)輸(shu)送(song)泵(beng)的(de)(de)(de)實際出(chu)口(kou)壓(ya)(ya)力(li)與每小時實際輸(shu)送(song)量(liang)(liang)之(zhi)乘積,該(gai)值越(yue)大(da)(da),其能(neng)力(li)指(zhi)數也越(yue)大(da)(da),電機(ji)的(de)(de)(de)功(gong)率也將越(yue)大(da)(da),由(you)此實現大(da)(da)排量(liang)(liang)、高揚程(cheng)的(de)(de)(de)目(mu)的(de)(de)(de)。科尼樂公司(si)在(zai)設計(ji)時,還(huan)采用(yong)了(le)高低(di)壓(ya)(ya)切換(huan)的(de)(de)(de)功(gong)能(neng)設計(ji),以滿足不同的(de)(de)(de)施工要求,在(zai)經濟(ji)狀態(tai)下,又(you)能(neng)產生較大(da)(da)的(de)(de)(de)輸(shu)送(song)量(liang)(liang),或(huo)者(zhe)以相同的(de)(de)(de)電機(ji)功(gong)率,產生較高的(de)(de)(de)出(chu)口(kou)壓(ya)(ya)力(li)。
