具體參數

隨(sui)著現代工(gong)業的興起，以混(hun)凝土(tu)為主材料的建(jian)設(she)方式已經(jing)成(cheng)為了(le)建(jian)筑(zhu)業施(shi)工(gong)的主要(yao)構(gou)造(zao)之(zhi)一(yi)，在各種(zhong)工(gong)程施(shi)工(gong)建(jian)設(she)中占據了(le)很大的比例，使(shi)得混(hun)凝土(tu)機械的發展經(jing)久不衰，且有越演越烈(lie)的形(xing)勢。拖(tuo)式混(hun)凝土(tu)泵(beng)，簡稱拖(tuo)泵(beng)，是各種(zhong)混(hun)凝土(tu)機械中的一(yi)種(zhong)，用(yong)于(yu)混(hun)凝土(tu)施(shi)工(gong)中的輸送和(he)澆注工(gong)作。

拖泵分類選型

37千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)（目前國(guo)內標準混凝(ning)土泵，37千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)以下為細石砂漿泵）、45千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)（柴(chai)油(you)）、132千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)（柴(chai)油(you)）、174千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)（柴(chai)油(you)）等。

選擇(ze)多大(da)(da)電(dian)(dian)機(ji)混凝(ning)土泵(beng)，首先要考(kao)慮變壓(ya)器容量，其次考(kao)慮距離混凝(ning)土泵(beng)的(de)遠近(jin)和線徑大(da)(da)小，以免壓(ya)降過(guo)(guo)大(da)(da)造(zao)(zao)成電(dian)(dian)流增高或(huo)跳閘(zha)停機(ji)，過(guo)(guo)大(da)(da)功(gong)率造(zao)(zao)成成本增加和使用(yong)不(bu)便。電(dian)(dian)機(ji)過(guo)(guo)小，同時也滿足不(bu)了工程需要。

混凝(ning)土(tu)輸(shu)(shu)(shu)送(song)(song)泵功(gong)率、混凝(ning)土(tu)輸(shu)(shu)(shu)送(song)(song)泵出口壓力、混凝(ning)土(tu)輸(shu)(shu)(shu)送(song)(song)泵輸(shu)(shu)(shu)送(song)(song)量(liang)之間的關(guan)系

一(yi)臺(tai)混凝土輸(shu)(shu)送泵的電(dian)機功率是決定(ding)出口壓力和輸(shu)(shu)送方量的前(qian)提(ti)條(tiao)件(jian)，在電(dian)機功率一(yi)定(ding)的情況下，壓力的升高必(bi)將使輸(shu)(shu)送量降低；相反，降低出口壓力，將會使輸(shu)(shu)送量增加。

為了(le)保證混(hun)凝(ning)土(tu)輸(shu)送(song)泵既要(yao)有較大(da)輸(shu)送(song)量，又能(neng)有一定的(de)(de)出(chu)口壓(ya)力(li)和與之相匹配(pei)的(de)(de)經濟功(gong)(gong)率，在混(hun)凝(ning)土(tu)輸(shu)送(song)泵的(de)(de)設計中，大(da)都采(cai)用(yong)了(le)恒(heng)(heng)功(gong)(gong)率柱塞泵；即恒(heng)(heng)功(gong)(gong)率值選(xuan)定后，當出(chu)口壓(ya)力(li)升高(gao)時，油(you)泵輸(shu)出(chu)排量會自動降低，達到(dao)與功(gong)(gong)率設計相對應的(de)(de)值；如果既要(yao)達到(dao)出(chu)口壓(ya)力(li)高(gao)，又想得到(dao)輸(shu)送(song)量大(da)的(de)(de)目的(de)(de)。惟一的(de)(de)途徑就(jiu)是增加電機(ji)功(gong)(gong)率。

因此(ci)，在(zai)(zai)國家新(xin)標準中(zhong)，引用(yong)了混凝土輸(shu)送(song)(song)泵(beng)的(de)(de)(de)(de)能(neng)(neng)力指(zhi)數(shu)概念（以(yi)MPa·m3/h為度(du)量(liang)單位）；即混凝土輸(shu)送(song)(song)泵(beng)的(de)(de)(de)(de)實際出(chu)口壓力與每小時實際輸(shu)送(song)(song)量(liang)之乘積，該(gai)值越大，其能(neng)(neng)力指(zhi)數(shu)也越大，電機的(de)(de)(de)(de)功(gong)(gong)(gong)率也將越大，由此(ci)實現大排量(liang)、高(gao)揚(yang)程的(de)(de)(de)(de)目的(de)(de)(de)(de)。科尼樂(le)公司在(zai)(zai)設計時，還采(cai)用(yong)了高(gao)低壓切換的(de)(de)(de)(de)功(gong)(gong)(gong)能(neng)(neng)設計，以(yi)滿足(zu)不(bu)同(tong)的(de)(de)(de)(de)施工(gong)要求，在(zai)(zai)經濟(ji)狀態下(xia)，又能(neng)(neng)產生(sheng)較大的(de)(de)(de)(de)輸(shu)送(song)(song)量(liang)，或者(zhe)以(yi)相同(tong)的(de)(de)(de)(de)電機功(gong)(gong)(gong)率，產生(sheng)較高(gao)的(de)(de)(de)(de)出(chu)口壓力。
