37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(目前國內標準混凝土(tu)泵,37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)以(yi)下為細石砂漿泵)、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)(da)電(dian)機混(hun)凝土泵(beng),首先要考慮(lv)變壓器容量,其次考慮(lv)距(ju)離混(hun)凝土泵(beng)的遠近和(he)線徑大(da)(da)小,以免壓降過大(da)(da)造(zao)成電(dian)流增(zeng)高或(huo)跳閘停機,過大(da)(da)功率造(zao)成成本增(zeng)加和(he)使用(yong)不(bu)便(bian)。電(dian)機過小,同時也滿足不(bu)了工程需要。
混凝土(tu)(tu)輸(shu)送泵(beng)功率、混凝土(tu)(tu)輸(shu)送泵(beng)出口壓(ya)力、混凝土(tu)(tu)輸(shu)送泵(beng)輸(shu)送量之間(jian)的關系。
一(yi)臺混凝土輸(shu)(shu)送泵的電(dian)機(ji)(ji)功(gong)率是決定(ding)出口壓力和輸(shu)(shu)送方量的前提條件,在(zai)電(dian)機(ji)(ji)功(gong)率一(yi)定(ding)的情況下,壓力的升高(gao)必將(jiang)使(shi)輸(shu)(shu)送量降(jiang)低;相(xiang)反(fan),降(jiang)低出口壓力,將(jiang)會使(shi)輸(shu)(shu)送量增加。
為了保證混凝(ning)土輸送(song)泵既(ji)要(yao)有較大(da)輸送(song)量(liang)(liang),又能有一定的出口(kou)壓(ya)力(li)(li)和與(yu)之相匹配的經濟(ji)功率(lv),在混凝(ning)土輸送(song)泵的設計(ji)中,大(da)都采(cai)用了恒(heng)功率(lv)柱塞泵;即恒(heng)功率(lv)值選定后,當出口(kou)壓(ya)力(li)(li)升高時,油(you)泵輸出排量(liang)(liang)會自(zi)動降低,達到(dao)與(yu)功率(lv)設計(ji)相對(dui)應的值;如(ru)果(guo)既(ji)要(yao)達到(dao)出口(kou)壓(ya)力(li)(li)高,又想得到(dao)輸送(song)量(liang)(liang)大(da)的目的。惟(wei)一的途(tu)徑就是增(zeng)加電機功率(lv)。
因(yin)此,在國家(jia)新標準中,引用了混凝土(tu)輸送(song)泵(beng)的(de)(de)(de)能(neng)力指(zhi)數概念(nian)(以(yi)MPa·m3/h為度量單位);即混凝土(tu)輸送(song)泵(beng)的(de)(de)(de)實(shi)際(ji)出(chu)口壓(ya)力與每(mei)小時(shi)實(shi)際(ji)輸送(song)量之乘(cheng)積,該(gai)值越大,其(qi)能(neng)力指(zhi)數也越大,電(dian)(dian)機的(de)(de)(de)功(gong)率也將(jiang)越大,由(you)此實(shi)現大排量、高揚程的(de)(de)(de)目的(de)(de)(de)。科尼樂公司(si)在設(she)計時(shi),還采用了高低壓(ya)切換(huan)的(de)(de)(de)功(gong)能(neng)設(she)計,以(yi)滿足(zu)不(bu)同(tong)的(de)(de)(de)施(shi)工要(yao)求,在經濟(ji)狀態下,又能(neng)產生(sheng)(sheng)較大的(de)(de)(de)輸送(song)量,或者以(yi)相(xiang)同(tong)的(de)(de)(de)電(dian)(dian)機功(gong)率,產生(sheng)(sheng)較高的(de)(de)(de)出(chu)口壓(ya)力。
