拖泵分類選型

37千(qian)(qian)(qian)(qian)(qian)瓦（目前國內標準(zhun)混凝土泵，37千(qian)(qian)(qian)(qian)(qian)瓦以(yi)下(xia)為細石砂(sha)漿泵）、45千(qian)(qian)(qian)(qian)(qian)瓦、55千(qian)(qian)(qian)(qian)(qian)瓦、75千(qian)(qian)(qian)(qian)(qian)瓦、90千(qian)(qian)(qian)(qian)(qian)瓦、110千(qian)(qian)(qian)(qian)(qian)瓦、130千(qian)(qian)(qian)(qian)(qian)瓦（柴油）、132千(qian)(qian)(qian)(qian)(qian)瓦、162千(qian)(qian)(qian)(qian)(qian)瓦（柴油）、174千(qian)(qian)(qian)(qian)(qian)瓦（柴油）等等。

選擇多大電(dian)(dian)機混凝土泵，首先要(yao)(yao)考慮(lv)變壓(ya)器(qi)容(rong)量(liang)，其次考慮(lv)距離混凝土泵的遠(yuan)近和線(xian)徑大小，以免壓(ya)降過大造成電(dian)(dian)流增高或跳閘停機，過大功(gong)率造成成本增加(jia)和使(shi)用不便(bian)。電(dian)(dian)機過小，同時也滿(man)足不了(le)工程需要(yao)(yao)。

混(hun)凝土(tu)(tu)輸(shu)(shu)送泵功(gong)率、混(hun)凝土(tu)(tu)輸(shu)(shu)送泵出(chu)口壓力、混(hun)凝土(tu)(tu)輸(shu)(shu)送泵輸(shu)(shu)送量之間的(de)關系

一臺混凝土輸(shu)送(song)(song)泵的(de)(de)電機功率(lv)(lv)是決(jue)定出口(kou)壓力和輸(shu)送(song)(song)方量的(de)(de)前(qian)提條(tiao)件(jian)，在電機功率(lv)(lv)一定的(de)(de)情況下，壓力的(de)(de)升(sheng)高(gao)必將(jiang)使輸(shu)送(song)(song)量降低(di)(di)；相反，降低(di)(di)出口(kou)壓力，將(jiang)會使輸(shu)送(song)(song)量增加。

為(wei)了保證混凝(ning)土(tu)輸(shu)(shu)(shu)(shu)送(song)(song)泵既要有較(jiao)大輸(shu)(shu)(shu)(shu)送(song)(song)量(liang)，又能有一定的(de)出(chu)口(kou)壓(ya)力和與(yu)之相(xiang)(xiang)匹配的(de)經濟功率(lv)(lv)，在混凝(ning)土(tu)輸(shu)(shu)(shu)(shu)送(song)(song)泵的(de)設(she)計中，大都采用了恒(heng)功率(lv)(lv)柱塞泵；即恒(heng)功率(lv)(lv)值選(xuan)定后，當出(chu)口(kou)壓(ya)力升高時，油泵輸(shu)(shu)(shu)(shu)出(chu)排量(liang)會自動降低，達到(dao)與(yu)功率(lv)(lv)設(she)計相(xiang)(xiang)對應的(de)值；如果既要達到(dao)出(chu)口(kou)壓(ya)力高，又想(xiang)得到(dao)輸(shu)(shu)(shu)(shu)送(song)(song)量(liang)大的(de)目的(de)。惟一的(de)途徑就是增加電機功率(lv)(lv)。

因此，在(zai)國(guo)家(jia)新標準(zhun)中，引用(yong)了(le)混凝(ning)土(tu)輸送泵(beng)的能(neng)力指數概(gai)念(nian)（以(yi)MPa·m3/h為度量單位(wei)）；即混凝(ning)土(tu)輸送泵(beng)的實(shi)際(ji)(ji)出口(kou)壓力與每小時實(shi)際(ji)(ji)輸送量之乘積，該值越(yue)大，其(qi)能(neng)力指數也(ye)越(yue)大，電機的功(gong)率也(ye)將(jiang)越(yue)大，由(you)此實(shi)現大排(pai)量、高揚(yang)程的目的。科尼樂公司在(zai)設計時，還采用(yong)了(le)高低壓切換的功(gong)能(neng)設計，以(yi)滿(man)足不同的施(shi)工(gong)要(yao)求，在(zai)經濟狀態(tai)下，又能(neng)產生(sheng)較大的輸送量，或者以(yi)相同的電機功(gong)率，產生(sheng)較高的出口(kou)壓力。
