37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(目前國(guo)內標準混凝土泵,37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)以下為細石砂(sha)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(deng)等(deng)。
選擇多大(da)電機(ji)(ji)混凝土(tu)泵,首先要考(kao)(kao)慮(lv)變壓(ya)器容量(liang),其次考(kao)(kao)慮(lv)距離混凝土(tu)泵的遠近和(he)線徑大(da)小(xiao),以免壓(ya)降過大(da)造成(cheng)(cheng)電流增高或跳閘(zha)停機(ji)(ji),過大(da)功(gong)率造成(cheng)(cheng)成(cheng)(cheng)本增加和(he)使(shi)用(yong)不便。電機(ji)(ji)過小(xiao),同時也滿足不了工(gong)程需要。
混凝土輸送(song)泵功率、混凝土輸送(song)泵出口壓力、混凝土輸送(song)泵輸送(song)量之間的關系(xi)
一臺混凝土(tu)輸(shu)送泵的(de)電機功(gong)率(lv)是決定(ding)出(chu)口壓(ya)力(li)(li)和輸(shu)送方量(liang)(liang)的(de)前(qian)提(ti)條(tiao)件,在(zai)電機功(gong)率(lv)一定(ding)的(de)情(qing)況下,壓(ya)力(li)(li)的(de)升高必將使輸(shu)送量(liang)(liang)降低;相反,降低出(chu)口壓(ya)力(li)(li),將會使輸(shu)送量(liang)(liang)增加。
為了(le)(le)保證混凝(ning)(ning)土(tu)輸送(song)(song)(song)泵既要(yao)有(you)較大(da)輸送(song)(song)(song)量,又(you)能有(you)一定的(de)出(chu)口(kou)壓力(li)和(he)與之相(xiang)匹(pi)配的(de)經濟功(gong)(gong)(gong)率(lv)(lv),在混凝(ning)(ning)土(tu)輸送(song)(song)(song)泵的(de)設計中,大(da)都采用了(le)(le)恒功(gong)(gong)(gong)率(lv)(lv)柱塞(sai)泵;即恒功(gong)(gong)(gong)率(lv)(lv)值選(xuan)定后,當出(chu)口(kou)壓力(li)升高(gao)時,油泵輸出(chu)排(pai)量會自動降(jiang)低,達到(dao)與功(gong)(gong)(gong)率(lv)(lv)設計相(xiang)對(dui)應的(de)值;如果既要(yao)達到(dao)出(chu)口(kou)壓力(li)高(gao),又(you)想(xiang)得到(dao)輸送(song)(song)(song)量大(da)的(de)目(mu)的(de)。惟一的(de)途徑就是增加電(dian)機功(gong)(gong)(gong)率(lv)(lv)。
因此(ci),在國家新標準中,引用了(le)混(hun)凝(ning)土輸(shu)送泵(beng)的(de)能(neng)力指數(shu)概(gai)念(以(yi)MPa·m3/h為度量單位);即(ji)混(hun)凝(ning)土輸(shu)送泵(beng)的(de)實際出口(kou)壓力與每小時(shi)實際輸(shu)送量之乘積,該值越(yue)大,其能(neng)力指數(shu)也(ye)越(yue)大,電機(ji)的(de)功率(lv)也(ye)將越(yue)大,由此(ci)實現大排(pai)量、高揚程的(de)目的(de)。科(ke)尼(ni)樂公司在設(she)計(ji)時(shi),還采用了(le)高低(di)壓切換的(de)功能(neng)設(she)計(ji),以(yi)滿足不同的(de)施工要求,在經濟(ji)狀態下,又(you)能(neng)產(chan)生較大的(de)輸(shu)送量,或者以(yi)相同的(de)電機(ji)功率(lv),產(chan)生較高的(de)出口(kou)壓力。
