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

選擇多大(da)電(dian)機(ji)混(hun)凝(ning)土(tu)泵(beng)，首(shou)先要(yao)考慮變壓(ya)器容(rong)量，其次(ci)考慮距離(li)混(hun)凝(ning)土(tu)泵(beng)的遠(yuan)近和線徑大(da)小(xiao)，以免壓(ya)降(jiang)過(guo)大(da)造成(cheng)電(dian)流(liu)增高(gao)或跳閘停機(ji)，過(guo)大(da)功率(lv)造成(cheng)成(cheng)本增加和使用(yong)不便。電(dian)機(ji)過(guo)小(xiao)，同時也滿足不了工(gong)程需要(yao)。

混(hun)凝(ning)土輸(shu)送(song)泵功(gong)率、混(hun)凝(ning)土輸(shu)送(song)泵出口(kou)壓力、混(hun)凝(ning)土輸(shu)送(song)泵輸(shu)送(song)量之間(jian)的關系。

一臺混凝土輸(shu)(shu)(shu)送(song)泵的電機(ji)功率是(shi)決定出口壓力和(he)輸(shu)(shu)(shu)送(song)方量的前提條件，在電機(ji)功率一定的情況(kuang)下(xia)，壓力的升高必將使(shi)輸(shu)(shu)(shu)送(song)量降低；相反，降低出口壓力，將會使(shi)輸(shu)(shu)(shu)送(song)量增加。

為了保證混凝(ning)土(tu)輸送(song)(song)(song)泵(beng)既要(yao)有較(jiao)大輸送(song)(song)(song)量，又能(neng)有一(yi)定(ding)的(de)(de)(de)出(chu)口壓(ya)力和(he)與之相匹(pi)配的(de)(de)(de)經濟功(gong)率(lv)(lv)，在混凝(ning)土(tu)輸送(song)(song)(song)泵(beng)的(de)(de)(de)設計(ji)中，大都(dou)采用了恒(heng)功(gong)率(lv)(lv)柱塞泵(beng)；即恒(heng)功(gong)率(lv)(lv)值選定(ding)后，當出(chu)口壓(ya)力升高時，油泵(beng)輸出(chu)排量會(hui)自動降(jiang)低，達到(dao)與功(gong)率(lv)(lv)設計(ji)相對應的(de)(de)(de)值；如(ru)果既要(yao)達到(dao)出(chu)口壓(ya)力高，又想得(de)到(dao)輸送(song)(song)(song)量大的(de)(de)(de)目的(de)(de)(de)。惟一(yi)的(de)(de)(de)途徑就(jiu)是(shi)增加電機功(gong)率(lv)(lv)。

因此，在(zai)國家新標準(zhun)中，引(yin)用了混凝土(tu)輸(shu)(shu)送(song)泵的(de)(de)能(neng)力指(zhi)數概念（以(yi)MPa·m3/h為度量單位(wei)）；即混凝土(tu)輸(shu)(shu)送(song)泵的(de)(de)實際出口(kou)壓(ya)力與每小時實際輸(shu)(shu)送(song)量之乘積(ji)，該值越大(da)，其能(neng)力指(zhi)數也越大(da)，電機(ji)的(de)(de)功(gong)(gong)率也將越大(da)，由(you)此實現大(da)排量、高揚程的(de)(de)目(mu)的(de)(de)。科尼樂公司在(zai)設計時，還(huan)采(cai)用了高低(di)壓(ya)切換的(de)(de)功(gong)(gong)能(neng)設計，以(yi)滿足不同的(de)(de)施(shi)工要求，在(zai)經濟狀(zhuang)態下，又(you)能(neng)產(chan)生較大(da)的(de)(de)輸(shu)(shu)送(song)量，或(huo)者以(yi)相(xiang)同的(de)(de)電機(ji)功(gong)(gong)率，產(chan)生較高的(de)(de)出口(kou)壓(ya)力。
