37千(qian)(qian)(qian)(qian)(qian)瓦(目(mu)前國內(nei)標準混(hun)凝土泵,37千(qian)(qian)(qian)(qian)(qian)瓦以下為細(xi)石砂漿(jiang)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(xuan)擇多大(da)電(dian)機混(hun)凝(ning)(ning)土泵(beng),首先要(yao)考(kao)慮變壓(ya)器(qi)容量(liang),其次考(kao)慮距(ju)離混(hun)凝(ning)(ning)土泵(beng)的遠(yuan)近和線(xian)徑大(da)小,以免壓(ya)降過(guo)大(da)造(zao)成(cheng)(cheng)電(dian)流(liu)增高或跳(tiao)閘停機,過(guo)大(da)功率造(zao)成(cheng)(cheng)成(cheng)(cheng)本增加和使用不(bu)便(bian)。電(dian)機過(guo)小,同時(shi)也滿足(zu)不(bu)了工程(cheng)需(xu)要(yao)。
混凝(ning)土(tu)輸(shu)(shu)(shu)送(song)泵(beng)(beng)功率(lv)、混凝(ning)土(tu)輸(shu)(shu)(shu)送(song)泵(beng)(beng)出口壓力(li)、混凝(ning)土(tu)輸(shu)(shu)(shu)送(song)泵(beng)(beng)輸(shu)(shu)(shu)送(song)量之間的關系。
一(yi)臺混凝(ning)土輸送(song)(song)泵的(de)電機功率是決定出口壓力(li)和輸送(song)(song)方量的(de)前(qian)提條件,在電機功率一(yi)定的(de)情況下,壓力(li)的(de)升高必將使輸送(song)(song)量降(jiang)低;相(xiang)反,降(jiang)低出口壓力(li),將會使輸送(song)(song)量增加。
為了保證(zheng)混(hun)凝(ning)土輸(shu)(shu)送(song)泵既(ji)(ji)要有(you)較大(da)輸(shu)(shu)送(song)量(liang)(liang),又能有(you)一定的(de)(de)出(chu)(chu)口壓力(li)(li)和與之相(xiang)匹配的(de)(de)經濟功率(lv),在(zai)混(hun)凝(ning)土輸(shu)(shu)送(song)泵的(de)(de)設計(ji)中,大(da)都采用(yong)了恒(heng)功率(lv)柱塞(sai)泵;即恒(heng)功率(lv)值選定后(hou),當(dang)出(chu)(chu)口壓力(li)(li)升高時,油泵輸(shu)(shu)出(chu)(chu)排量(liang)(liang)會自(zi)動降低(di),達(da)到與功率(lv)設計(ji)相(xiang)對應的(de)(de)值;如果既(ji)(ji)要達(da)到出(chu)(chu)口壓力(li)(li)高,又想得(de)到輸(shu)(shu)送(song)量(liang)(liang)大(da)的(de)(de)目(mu)的(de)(de)。惟(wei)一的(de)(de)途徑就是增(zeng)加電機功率(lv)。
因(yin)此,在國(guo)家新(xin)標(biao)準中(zhong),引(yin)用了混凝土輸(shu)送(song)泵的(de)(de)能(neng)力(li)(li)(li)指數概念(以MPa·m3/h為(wei)度量(liang)單位);即(ji)混凝土輸(shu)送(song)泵的(de)(de)實(shi)(shi)際出口(kou)壓(ya)力(li)(li)(li)與每小時實(shi)(shi)際輸(shu)送(song)量(liang)之乘(cheng)積,該值越(yue)大,其能(neng)力(li)(li)(li)指數也(ye)(ye)越(yue)大,電(dian)機(ji)的(de)(de)功率也(ye)(ye)將越(yue)大,由(you)此實(shi)(shi)現大排量(liang)、高揚(yang)程的(de)(de)目的(de)(de)。科尼樂(le)公司(si)在設(she)計(ji)時,還采用了高低壓(ya)切換的(de)(de)功能(neng)設(she)計(ji),以滿(man)足不同的(de)(de)施工要求,在經濟狀態下,又能(neng)產(chan)生(sheng)較大的(de)(de)輸(shu)送(song)量(liang),或者以相同的(de)(de)電(dian)機(ji)功率,產(chan)生(sheng)較高的(de)(de)出口(kou)壓(ya)力(li)(li)(li)。
