37千(qian)(qian)瓦(wa)(wa)(wa)(目前國內標準混(hun)凝(ning)土泵,37千(qian)(qian)瓦(wa)(wa)(wa)以下為細石砂漿泵)、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(chai)油(you)(you))、132千(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油(you)(you))、174千(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油(you)(you))等(deng)等(deng)。
選擇多大電機混凝(ning)土(tu)泵,首先要考慮變(bian)壓器容量,其次考慮距(ju)離混凝(ning)土(tu)泵的遠近和(he)線徑大小(xiao),以免壓降過(guo)大造(zao)成電流增高或(huo)跳閘停機,過(guo)大功率造(zao)成成本增加和(he)使用不便。電機過(guo)小(xiao),同時也滿足不了工程(cheng)需要。
混凝(ning)(ning)(ning)土輸送(song)泵(beng)功率、混凝(ning)(ning)(ning)土輸送(song)泵(beng)出(chu)口壓力、混凝(ning)(ning)(ning)土輸送(song)泵(beng)輸送(song)量之間(jian)的關系
一臺混凝土輸送(song)泵(beng)的電(dian)機功率是決定出口壓(ya)力和輸送(song)方量(liang)的前提條件(jian),在(zai)電(dian)機功率一定的情況下,壓(ya)力的升高必將使(shi)輸送(song)量(liang)降低;相反,降低出口壓(ya)力,將會(hui)使(shi)輸送(song)量(liang)增加。
為了保證(zheng)混(hun)凝(ning)(ning)土(tu)輸送(song)泵(beng)(beng)既要(yao)有較大(da)輸送(song)量,又(you)(you)能有一(yi)定(ding)的(de)(de)(de)出(chu)(chu)口(kou)壓(ya)(ya)力和與(yu)之相(xiang)匹配(pei)的(de)(de)(de)經濟功(gong)(gong)率(lv)(lv),在(zai)混(hun)凝(ning)(ning)土(tu)輸送(song)泵(beng)(beng)的(de)(de)(de)設(she)計(ji)中,大(da)都采(cai)用了恒(heng)功(gong)(gong)率(lv)(lv)柱塞泵(beng)(beng);即(ji)恒(heng)功(gong)(gong)率(lv)(lv)值(zhi)選定(ding)后,當出(chu)(chu)口(kou)壓(ya)(ya)力升高時,油(you)泵(beng)(beng)輸出(chu)(chu)排量會(hui)自動降低,達到與(yu)功(gong)(gong)率(lv)(lv)設(she)計(ji)相(xiang)對應的(de)(de)(de)值(zhi);如果既要(yao)達到出(chu)(chu)口(kou)壓(ya)(ya)力高,又(you)(you)想得到輸送(song)量大(da)的(de)(de)(de)目的(de)(de)(de)。惟一(yi)的(de)(de)(de)途徑就是增加電機(ji)功(gong)(gong)率(lv)(lv)。
因此,在國家(jia)新標準中,引用了(le)混凝土(tu)輸送(song)(song)泵的(de)(de)能力指(zhi)數(shu)概念(nian)(以MPa·m3/h為(wei)度量(liang)單位);即(ji)混凝土(tu)輸送(song)(song)泵的(de)(de)實(shi)際(ji)出口壓(ya)力與每小時實(shi)際(ji)輸送(song)(song)量(liang)之乘(cheng)積,該值越(yue)(yue)大(da),其能力指(zhi)數(shu)也越(yue)(yue)大(da),電(dian)機的(de)(de)功率(lv)也將越(yue)(yue)大(da),由此實(shi)現(xian)大(da)排量(liang)、高(gao)揚(yang)程的(de)(de)目的(de)(de)。科尼樂公(gong)司在設計時,還采用了(le)高(gao)低壓(ya)切(qie)換的(de)(de)功能設計,以滿足不同的(de)(de)施工要(yao)求(qiu),在經(jing)濟狀態下(xia),又(you)能產生較(jiao)大(da)的(de)(de)輸送(song)(song)量(liang),或者以相同的(de)(de)電(dian)機功率(lv),產生較(jiao)高(gao)的(de)(de)出口壓(ya)力。
