37千(qian)(qian)瓦(wa)(wa)(wa)(目前國內(nei)標準混(hun)凝土泵(beng),37千(qian)(qian)瓦(wa)(wa)(wa)以(yi)下(xia)為(wei)細石(shi)砂漿(jiang)泵(beng))、45千(qian)(qian)瓦(wa)(wa)(wa)、55千(qian)(qian)瓦(wa)(wa)(wa)、75千(qian)(qian)瓦(wa)(wa)(wa)、90千(qian)(qian)瓦(wa)(wa)(wa)、110千(qian)(qian)瓦(wa)(wa)(wa)、130千(qian)(qian)瓦(wa)(wa)(wa)(柴油)、132千(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)瓦(wa)(wa)(wa)(柴油)、174千(qian)(qian)瓦(wa)(wa)(wa)(柴油)等等。
選擇多(duo)大電機(ji)混(hun)凝土(tu)泵(beng),首(shou)先(xian)要(yao)考慮(lv)(lv)變壓器容量,其次(ci)考慮(lv)(lv)距(ju)離混(hun)凝土(tu)泵(beng)的遠近和線徑大小(xiao),以免壓降過(guo)大造(zao)成(cheng)電流增高或(huo)跳閘停機(ji),過(guo)大功率造(zao)成(cheng)成(cheng)本增加和使用不便。電機(ji)過(guo)小(xiao),同(tong)時也滿足不了工程需要(yao)。
混(hun)凝土(tu)輸(shu)送(song)泵功率、混(hun)凝土(tu)輸(shu)送(song)泵出口壓力、混(hun)凝土(tu)輸(shu)送(song)泵輸(shu)送(song)量之間的關系
一(yi)臺混凝土(tu)輸(shu)送(song)(song)泵的(de)(de)電機(ji)(ji)功率是決定出(chu)口(kou)壓力和輸(shu)送(song)(song)方量的(de)(de)前提條件,在(zai)電機(ji)(ji)功率一(yi)定的(de)(de)情況下,壓力的(de)(de)升高必將使輸(shu)送(song)(song)量降(jiang)低;相反(fan),降(jiang)低出(chu)口(kou)壓力,將會使輸(shu)送(song)(song)量增加。
為了保證混凝(ning)土(tu)輸(shu)送(song)泵(beng)既(ji)要有較大輸(shu)送(song)量,又能有一定(ding)的出口壓(ya)力和(he)與(yu)(yu)之相(xiang)匹配的經濟(ji)功率(lv)(lv)(lv),在混凝(ning)土(tu)輸(shu)送(song)泵(beng)的設(she)計中,大都采用了恒功率(lv)(lv)(lv)柱塞(sai)泵(beng);即恒功率(lv)(lv)(lv)值(zhi)選(xuan)定(ding)后,當出口壓(ya)力升(sheng)高時,油泵(beng)輸(shu)出排量會自動(dong)降低,達(da)到與(yu)(yu)功率(lv)(lv)(lv)設(she)計相(xiang)對應的值(zhi);如果既(ji)要達(da)到出口壓(ya)力高,又想得到輸(shu)送(song)量大的目的。惟一的途(tu)徑就是(shi)增(zeng)加電機功率(lv)(lv)(lv)。
因此(ci)(ci),在國家新(xin)標準中,引用了混(hun)凝土(tu)輸(shu)送(song)(song)(song)泵的(de)(de)(de)(de)能(neng)力指數(shu)概念(以MPa·m3/h為度(du)量單位);即混(hun)凝土(tu)輸(shu)送(song)(song)(song)泵的(de)(de)(de)(de)實(shi)際出(chu)口壓(ya)力與每小時(shi)實(shi)際輸(shu)送(song)(song)(song)量之乘積,該值越大(da)(da),其能(neng)力指數(shu)也(ye)越大(da)(da),電機(ji)的(de)(de)(de)(de)功(gong)率也(ye)將越大(da)(da),由此(ci)(ci)實(shi)現大(da)(da)排量、高(gao)(gao)揚程的(de)(de)(de)(de)目的(de)(de)(de)(de)。科尼樂公司(si)在設計時(shi),還(huan)采(cai)用了高(gao)(gao)低壓(ya)切換的(de)(de)(de)(de)功(gong)能(neng)設計,以滿足不同(tong)的(de)(de)(de)(de)施工要求,在經濟狀(zhuang)態(tai)下,又能(neng)產生較大(da)(da)的(de)(de)(de)(de)輸(shu)送(song)(song)(song)量,或者以相同(tong)的(de)(de)(de)(de)電機(ji)功(gong)率,產生較高(gao)(gao)的(de)(de)(de)(de)出(chu)口壓(ya)力。
