37千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)（目前國內標準(zhun)混凝土泵，37千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)以下(xia)為細石砂(sha)漿(jiang)泵）、45千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、55千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、75千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、90千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、110千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、130千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)（柴油）、132千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)（柴油）、174千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)（柴油）等等。

選擇多大(da)電(dian)機(ji)混凝(ning)土泵，首先(xian)要(yao)考慮變壓(ya)器容量，其次考慮距(ju)離混凝(ning)土泵的遠近(jin)和線(xian)徑大(da)小，以免(mian)壓(ya)降過大(da)造(zao)(zao)成(cheng)電(dian)流增高或跳閘停機(ji)，過大(da)功率(lv)造(zao)(zao)成(cheng)成(cheng)本增加和使用不便(bian)。電(dian)機(ji)過小，同時也滿足不了工程需要(yao)。

混凝土輸(shu)(shu)送(song)泵功率、混凝土輸(shu)(shu)送(song)泵出口壓力、混凝土輸(shu)(shu)送(song)泵輸(shu)(shu)送(song)量(liang)之間的關系

一臺混凝土輸(shu)送(song)泵的(de)(de)電機(ji)功率是決定出(chu)口(kou)壓(ya)(ya)力和輸(shu)送(song)方量的(de)(de)前提條件，在(zai)電機(ji)功率一定的(de)(de)情(qing)況下，壓(ya)(ya)力的(de)(de)升(sheng)高必將(jiang)使(shi)輸(shu)送(song)量降低(di)；相反，降低(di)出(chu)口(kou)壓(ya)(ya)力，將(jiang)會使(shi)輸(shu)送(song)量增加。

為了保(bao)證混凝土輸(shu)(shu)送(song)泵既要有(you)較(jiao)大輸(shu)(shu)送(song)量，又能有(you)一定(ding)的(de)(de)(de)出(chu)(chu)口(kou)壓(ya)力(li)和與之(zhi)相匹(pi)配(pei)的(de)(de)(de)經濟功率(lv)(lv)(lv)，在混凝土輸(shu)(shu)送(song)泵的(de)(de)(de)設(she)計中(zhong)，大都(dou)采用了恒功率(lv)(lv)(lv)柱塞泵；即恒功率(lv)(lv)(lv)值選定(ding)后(hou)，當出(chu)(chu)口(kou)壓(ya)力(li)升高(gao)時，油泵輸(shu)(shu)出(chu)(chu)排量會自動降低，達(da)到與功率(lv)(lv)(lv)設(she)計相對應的(de)(de)(de)值；如(ru)果既要達(da)到出(chu)(chu)口(kou)壓(ya)力(li)高(gao)，又想得到輸(shu)(shu)送(song)量大的(de)(de)(de)目(mu)的(de)(de)(de)。惟一的(de)(de)(de)途徑就(jiu)是增(zeng)加電機(ji)功率(lv)(lv)(lv)。

因此，在國(guo)家新標準(zhun)中，引用了(le)混凝(ning)土(tu)輸(shu)送(song)泵的(de)(de)能力指數概念（以(yi)MPa·m3/h為度(du)量單位(wei)）；即混凝(ning)土(tu)輸(shu)送(song)泵的(de)(de)實(shi)(shi)際出口(kou)壓力與(yu)每(mei)小時(shi)實(shi)(shi)際輸(shu)送(song)量之乘積，該(gai)值(zhi)越(yue)大(da)，其能力指數也越(yue)大(da)，電(dian)(dian)機(ji)的(de)(de)功(gong)率也將越(yue)大(da)，由(you)此實(shi)(shi)現(xian)大(da)排量、高(gao)揚程(cheng)的(de)(de)目的(de)(de)。科(ke)尼樂公(gong)司在設(she)計時(shi)，還采用了(le)高(gao)低壓切換的(de)(de)功(gong)能設(she)計，以(yi)滿(man)足不同的(de)(de)施工要求(qiu)，在經濟狀態下，又能產生(sheng)較(jiao)大(da)的(de)(de)輸(shu)送(song)量，或者以(yi)相同的(de)(de)電(dian)(dian)機(ji)功(gong)率，產生(sheng)較(jiao)高(gao)的(de)(de)出口(kou)壓力。
