拖泵分類選(xuan)型

37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)（目前國內標準混凝土(tu)泵(beng)，37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)以下為細石(shi)砂漿(jiang)泵(beng)）、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)（柴油(you)）、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)（柴油(you)）、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)（柴油(you)）等等。

選擇多大(da)電(dian)機混(hun)(hun)凝(ning)土(tu)泵，首先要考(kao)慮(lv)變壓(ya)器容量，其次考(kao)慮(lv)距離混(hun)(hun)凝(ning)土(tu)泵的遠近和線徑大(da)小，以免(mian)壓(ya)降過大(da)造成電(dian)流增高或跳閘(zha)停機，過大(da)功率造成成本增加和使(shi)用(yong)不便。電(dian)機過小，同時也(ye)滿足(zu)不了工程(cheng)需要。

混(hun)凝土輸(shu)(shu)送(song)泵(beng)功率、混(hun)凝土輸(shu)(shu)送(song)泵(beng)出(chu)口壓力、混(hun)凝土輸(shu)(shu)送(song)泵(beng)輸(shu)(shu)送(song)量(liang)之間的關系(xi)。

一臺(tai)混(hun)凝(ning)土輸送(song)(song)泵的電機功率是決(jue)定出口(kou)壓力和(he)輸送(song)(song)方量(liang)的前提條件(jian)，在電機功率一定的情況(kuang)下，壓力的升高必將(jiang)(jiang)使(shi)輸送(song)(song)量(liang)降(jiang)(jiang)低；相反，降(jiang)(jiang)低出口(kou)壓力，將(jiang)(jiang)會使(shi)輸送(song)(song)量(liang)增加。

為了保(bao)證混(hun)(hun)凝土輸(shu)(shu)(shu)送(song)泵既(ji)要有(you)較大輸(shu)(shu)(shu)送(song)量(liang)，又能有(you)一定的(de)出(chu)口(kou)壓力和(he)與之相(xiang)(xiang)匹配的(de)經(jing)濟功(gong)(gong)率(lv)(lv)，在(zai)混(hun)(hun)凝土輸(shu)(shu)(shu)送(song)泵的(de)設計中，大都采用了恒功(gong)(gong)率(lv)(lv)柱塞泵；即恒功(gong)(gong)率(lv)(lv)值選定后(hou)，當出(chu)口(kou)壓力升高時，油泵輸(shu)(shu)(shu)出(chu)排量(liang)會自動降低(di)，達到(dao)(dao)與功(gong)(gong)率(lv)(lv)設計相(xiang)(xiang)對應的(de)值；如果既(ji)要達到(dao)(dao)出(chu)口(kou)壓力高，又想得到(dao)(dao)輸(shu)(shu)(shu)送(song)量(liang)大的(de)目的(de)。惟一的(de)途徑就是(shi)增加(jia)電機功(gong)(gong)率(lv)(lv)。

因此，在國家新標準中，引(yin)用了混(hun)凝土輸(shu)(shu)送(song)(song)(song)泵的(de)能力(li)指數概念（以MPa·m3/h為度(du)量(liang)單(dan)位）；即混(hun)凝土輸(shu)(shu)送(song)(song)(song)泵的(de)實際出口(kou)壓力(li)與每小時(shi)實際輸(shu)(shu)送(song)(song)(song)量(liang)之乘(cheng)積，該值越大(da)(da)，其能力(li)指數也越大(da)(da)，電機(ji)的(de)功(gong)(gong)率也將越大(da)(da)，由(you)此實現大(da)(da)排量(liang)、高(gao)(gao)揚(yang)程的(de)目(mu)的(de)。科尼(ni)樂公(gong)司在設計時(shi)，還采(cai)用了高(gao)(gao)低壓切換的(de)功(gong)(gong)能設計，以滿足(zu)不同(tong)的(de)施工要求(qiu)，在經濟狀(zhuang)態(tai)下，又能產生較(jiao)(jiao)大(da)(da)的(de)輸(shu)(shu)送(song)(song)(song)量(liang)，或者以相同(tong)的(de)電機(ji)功(gong)(gong)率，產生較(jiao)(jiao)高(gao)(gao)的(de)出口(kou)壓力(li)。
