37千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)（目前國內標準混凝土泵(beng)，37千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)以(yi)下為細石砂漿泵(beng)）、45千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)（柴(chai)(chai)油）、132千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)（柴(chai)(chai)油）、174千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)（柴(chai)(chai)油）等(deng)(deng)等(deng)(deng)。

選擇多大電機(ji)混凝土(tu)泵，首(shou)先(xian)要考慮變壓器容量(liang)，其次(ci)考慮距離混凝土(tu)泵的遠近和線徑大小(xiao)，以(yi)免壓降過大造(zao)成(cheng)電流增高或跳閘停機(ji)，過大功率造(zao)成(cheng)成(cheng)本增加和使用不(bu)便(bian)。電機(ji)過小(xiao)，同(tong)時也滿足不(bu)了工程需要。

混(hun)凝(ning)土輸(shu)(shu)送(song)(song)泵(beng)功率(lv)、混(hun)凝(ning)土輸(shu)(shu)送(song)(song)泵(beng)出口(kou)壓力、混(hun)凝(ning)土輸(shu)(shu)送(song)(song)泵(beng)輸(shu)(shu)送(song)(song)量之間的關系。

一臺混凝土輸(shu)送泵(beng)的電(dian)機功率是決(jue)定出口壓(ya)力和輸(shu)送方量(liang)的前提(ti)條件，在電(dian)機功率一定的情(qing)況(kuang)下，壓(ya)力的升(sheng)高必將使輸(shu)送量(liang)降低(di)；相反(fan)，降低(di)出口壓(ya)力，將會使輸(shu)送量(liang)增加(jia)。

為了保證(zheng)混凝土輸(shu)送泵既要(yao)有(you)較(jiao)大輸(shu)送量(liang)(liang)，又(you)能有(you)一定的(de)(de)(de)出口(kou)壓(ya)力和(he)與之相匹配的(de)(de)(de)經(jing)濟功(gong)(gong)率(lv)，在混凝土輸(shu)送泵的(de)(de)(de)設計(ji)中，大都采用(yong)了恒功(gong)(gong)率(lv)柱塞泵；即(ji)恒功(gong)(gong)率(lv)值選定后(hou)，當出口(kou)壓(ya)力升高(gao)時(shi)，油泵輸(shu)出排量(liang)(liang)會自動降低，達(da)到(dao)與功(gong)(gong)率(lv)設計(ji)相對(dui)應的(de)(de)(de)值；如果既要(yao)達(da)到(dao)出口(kou)壓(ya)力高(gao)，又(you)想得到(dao)輸(shu)送量(liang)(liang)大的(de)(de)(de)目的(de)(de)(de)。惟(wei)一的(de)(de)(de)途徑就是增加電機功(gong)(gong)率(lv)。

因此(ci)，在(zai)(zai)國家新標準中，引用了混凝土(tu)(tu)輸送(song)(song)(song)泵(beng)的(de)(de)(de)(de)(de)能力指數(shu)概念（以MPa·m3/h為度量(liang)單位）；即(ji)混凝土(tu)(tu)輸送(song)(song)(song)泵(beng)的(de)(de)(de)(de)(de)實(shi)際(ji)(ji)出(chu)口(kou)壓(ya)力與每小時實(shi)際(ji)(ji)輸送(song)(song)(song)量(liang)之乘積，該值越大，其能力指數(shu)也(ye)越大，電機的(de)(de)(de)(de)(de)功率(lv)也(ye)將越大，由此(ci)實(shi)現大排量(liang)、高(gao)揚程的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)。科尼(ni)樂公司(si)在(zai)(zai)設(she)計(ji)時，還采用了高(gao)低壓(ya)切換(huan)的(de)(de)(de)(de)(de)功能設(she)計(ji)，以滿足不同的(de)(de)(de)(de)(de)施工要求，在(zai)(zai)經(jing)濟狀態下，又能產(chan)(chan)生(sheng)較(jiao)大的(de)(de)(de)(de)(de)輸送(song)(song)(song)量(liang)，或者以相(xiang)同的(de)(de)(de)(de)(de)電機功率(lv)，產(chan)(chan)生(sheng)較(jiao)高(gao)的(de)(de)(de)(de)(de)出(chu)口(kou)壓(ya)力。
