37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(目前國內標準混凝(ning)土(tu)泵(beng),37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)以下(xia)為(wei)細石砂漿(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(chai)(chai)油)、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)(chai)油)、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)(chai)油)等(deng)等(deng)。
選擇多大電(dian)機混(hun)凝土泵,首先要考慮(lv)(lv)變壓器容量,其次考慮(lv)(lv)距離混(hun)凝土泵的遠近和線徑大小,以免(mian)壓降過大造成電(dian)流增(zeng)高(gao)或跳閘停機,過大功率造成成本增(zeng)加和使(shi)用不(bu)便。電(dian)機過小,同時也(ye)滿足(zu)不(bu)了工(gong)程(cheng)需要。
混(hun)(hun)凝土輸(shu)(shu)送泵功率、混(hun)(hun)凝土輸(shu)(shu)送泵出口壓力、混(hun)(hun)凝土輸(shu)(shu)送泵輸(shu)(shu)送量之間的關(guan)系
一臺混凝(ning)土輸送(song)泵的(de)(de)電(dian)機(ji)功率(lv)是(shi)決定(ding)出口(kou)壓(ya)力和輸送(song)方量(liang)的(de)(de)前提條件,在電(dian)機(ji)功率(lv)一定(ding)的(de)(de)情況下,壓(ya)力的(de)(de)升高必將使輸送(song)量(liang)降低(di);相反,降低(di)出口(kou)壓(ya)力,將會(hui)使輸送(song)量(liang)增加。
為了(le)保證混凝土輸(shu)送(song)泵既(ji)要(yao)有(you)較大輸(shu)送(song)量,又能有(you)一(yi)定(ding)的(de)(de)出(chu)口壓(ya)力(li)和與之相(xiang)匹(pi)配的(de)(de)經濟功(gong)率(lv),在(zai)混凝土輸(shu)送(song)泵的(de)(de)設(she)計中,大都采用了(le)恒功(gong)率(lv)柱(zhu)塞泵;即恒功(gong)率(lv)值(zhi)(zhi)選定(ding)后,當出(chu)口壓(ya)力(li)升高時(shi),油泵輸(shu)出(chu)排量會自(zi)動降低,達(da)到與功(gong)率(lv)設(she)計相(xiang)對應的(de)(de)值(zhi)(zhi);如(ru)果既(ji)要(yao)達(da)到出(chu)口壓(ya)力(li)高,又想得到輸(shu)送(song)量大的(de)(de)目的(de)(de)。惟一(yi)的(de)(de)途徑就是增加(jia)電機(ji)功(gong)率(lv)。
因此,在(zai)(zai)國(guo)家(jia)新標準中,引用了混凝土輸(shu)(shu)送(song)泵的(de)(de)(de)能力指(zhi)數概念(以MPa·m3/h為度量(liang)(liang)(liang)單(dan)位);即混凝土輸(shu)(shu)送(song)泵的(de)(de)(de)實際出口壓力與(yu)每小時實際輸(shu)(shu)送(song)量(liang)(liang)(liang)之乘積,該值越大(da)(da),其能力指(zhi)數也越大(da)(da),電機(ji)的(de)(de)(de)功(gong)率也將越大(da)(da),由此實現大(da)(da)排量(liang)(liang)(liang)、高揚程(cheng)的(de)(de)(de)目的(de)(de)(de)。科尼(ni)樂公司在(zai)(zai)設(she)計時,還(huan)采(cai)用了高低壓切換的(de)(de)(de)功(gong)能設(she)計,以滿足不同的(de)(de)(de)施工要求(qiu),在(zai)(zai)經濟狀態下(xia),又能產(chan)生較(jiao)大(da)(da)的(de)(de)(de)輸(shu)(shu)送(song)量(liang)(liang)(liang),或者(zhe)以相同的(de)(de)(de)電機(ji)功(gong)率,產(chan)生較(jiao)高的(de)(de)(de)出口壓力。
