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

選擇多大(da)(da)電(dian)(dian)機混凝土泵，首先要(yao)考慮(lv)(lv)變壓器容量，其次考慮(lv)(lv)距離混凝土泵的遠近(jin)和線徑大(da)(da)小，以免壓降過(guo)大(da)(da)造成電(dian)(dian)流增高或(huo)跳閘(zha)停機，過(guo)大(da)(da)功率造成成本增加和使用不便。電(dian)(dian)機過(guo)小，同(tong)時也滿足不了工(gong)程需要(yao)。

混凝土輸送(song)(song)泵功率、混凝土輸送(song)(song)泵出(chu)口壓(ya)力、混凝土輸送(song)(song)泵輸送(song)(song)量之間的關(guan)系。

一(yi)臺混凝土輸(shu)(shu)送泵(beng)的電機功率是決定(ding)(ding)出(chu)口壓(ya)力和(he)輸(shu)(shu)送方量(liang)的前提條件(jian)，在電機功率一(yi)定(ding)(ding)的情況下，壓(ya)力的升(sheng)高必將使(shi)輸(shu)(shu)送量(liang)降(jiang)(jiang)低；相反，降(jiang)(jiang)低出(chu)口壓(ya)力，將會使(shi)輸(shu)(shu)送量(liang)增加。

為了(le)保證混(hun)凝土輸(shu)送(song)泵(beng)既要有較大輸(shu)送(song)量(liang)，又能有一(yi)定的(de)出口(kou)壓(ya)力(li)和(he)與(yu)(yu)之(zhi)相匹配的(de)經(jing)濟功(gong)(gong)率(lv)，在混(hun)凝土輸(shu)送(song)泵(beng)的(de)設計(ji)中，大都采(cai)用了(le)恒(heng)功(gong)(gong)率(lv)柱塞泵(beng)；即恒(heng)功(gong)(gong)率(lv)值選定后，當出口(kou)壓(ya)力(li)升高時(shi)，油泵(beng)輸(shu)出排量(liang)會(hui)自動降低，達(da)到(dao)與(yu)(yu)功(gong)(gong)率(lv)設計(ji)相對應的(de)值；如(ru)果既要達(da)到(dao)出口(kou)壓(ya)力(li)高，又想(xiang)得到(dao)輸(shu)送(song)量(liang)大的(de)目的(de)。惟一(yi)的(de)途徑就是增加電機功(gong)(gong)率(lv)。

因此(ci)，在(zai)國家新(xin)標準中，引(yin)用了混(hun)凝土輸(shu)送泵(beng)的(de)能(neng)力指數(shu)概念（以MPa·m3/h為(wei)度量單位）；即(ji)混(hun)凝土輸(shu)送泵(beng)的(de)實際(ji)出(chu)(chu)口壓力與每小時實際(ji)輸(shu)送量之乘積，該值越大(da)(da)，其能(neng)力指數(shu)也越大(da)(da)，電機的(de)功(gong)率也將越大(da)(da)，由此(ci)實現大(da)(da)排量、高揚程的(de)目的(de)。科尼樂(le)公(gong)司(si)在(zai)設計(ji)時，還采用了高低(di)壓切(qie)換的(de)功(gong)能(neng)設計(ji)，以滿(man)足不同的(de)施工(gong)要求，在(zai)經濟狀態(tai)下，又能(neng)產(chan)生較大(da)(da)的(de)輸(shu)送量，或(huo)者以相同的(de)電機功(gong)率，產(chan)生較高的(de)出(chu)(chu)口壓力。
