37千(qian)(qian)(qian)瓦(wa)(wa)(目前國內(nei)標準混凝土泵,37千(qian)(qian)(qian)瓦(wa)(wa)以(yi)下為細石(shi)砂漿(jiang)泵)、45千(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)瓦(wa)(wa)(柴油(you)(you))、132千(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(柴油(you)(you))、174千(qian)(qian)(qian)瓦(wa)(wa)(柴油(you)(you))等等。
選(xuan)擇多大電(dian)(dian)機混(hun)凝(ning)土(tu)泵,首先(xian)要考慮變壓(ya)器容(rong)量,其次考慮距離混(hun)凝(ning)土(tu)泵的遠近和線徑大小,以免壓(ya)降過大造(zao)成(cheng)電(dian)(dian)流(liu)增高或(huo)跳閘停機,過大功率造(zao)成(cheng)成(cheng)本增加和使用不(bu)便。電(dian)(dian)機過小,同時也滿足不(bu)了工程需要。
混凝土輸送(song)泵功率、混凝土輸送(song)泵出口(kou)壓力、混凝土輸送(song)泵輸送(song)量之間的關系。
一(yi)臺混凝土輸送(song)泵的電(dian)機(ji)功率是決定出口壓力(li)和輸送(song)方量(liang)的前提條件(jian),在電(dian)機(ji)功率一(yi)定的情(qing)況(kuang)下,壓力(li)的升高必將使輸送(song)量(liang)降(jiang)低;相反,降(jiang)低出口壓力(li),將會使輸送(song)量(liang)增加(jia)。
為了保證混凝(ning)土輸(shu)送(song)泵既要(yao)有較大(da)輸(shu)送(song)量,又能有一定(ding)的(de)出(chu)(chu)口(kou)壓(ya)力(li)(li)和與(yu)之(zhi)相匹配的(de)經濟功(gong)率,在(zai)混凝(ning)土輸(shu)送(song)泵的(de)設(she)計中,大(da)都采用了恒功(gong)率柱(zhu)塞泵;即(ji)恒功(gong)率值(zhi)選定(ding)后,當出(chu)(chu)口(kou)壓(ya)力(li)(li)升高(gao)時,油泵輸(shu)出(chu)(chu)排量會自(zi)動降低,達到與(yu)功(gong)率設(she)計相對應的(de)值(zhi);如(ru)果既要(yao)達到出(chu)(chu)口(kou)壓(ya)力(li)(li)高(gao),又想得到輸(shu)送(song)量大(da)的(de)目的(de)。惟一的(de)途徑就是增加電(dian)機功(gong)率。
因此,在國家(jia)新標準中(zhong),引用了混(hun)凝土(tu)輸送(song)(song)(song)泵的能力指數概念(以(yi)MPa·m3/h為度量(liang)單位);即混(hun)凝土(tu)輸送(song)(song)(song)泵的實際出口壓(ya)力與每小(xiao)時實際輸送(song)(song)(song)量(liang)之乘(cheng)積,該(gai)值越大(da)(da)(da),其能力指數也(ye)越大(da)(da)(da),電機的功率也(ye)將越大(da)(da)(da),由(you)此實現大(da)(da)(da)排量(liang)、高揚程的目的。科尼樂公司在設計時,還采用了高低壓(ya)切(qie)換的功能設計,以(yi)滿(man)足(zu)不同(tong)的施(shi)工要(yao)求,在經濟狀態下,又能產(chan)生(sheng)較大(da)(da)(da)的輸送(song)(song)(song)量(liang),或(huo)者以(yi)相同(tong)的電機功率,產(chan)生(sheng)較高的出口壓(ya)力。
