選擇多大(da)電機(ji)(ji)混凝土(tu)泵,首先要考(kao)慮變壓(ya)器(qi)容量,其次考(kao)慮距離混凝土(tu)泵的遠近和(he)線(xian)徑大(da)小,以免(mian)壓(ya)降過大(da)造(zao)成(cheng)電流增高或跳(tiao)閘停機(ji)(ji),過大(da)功率造(zao)成(cheng)成(cheng)本(ben)增加和(he)使(shi)用不便。電機(ji)(ji)過小,同時也滿足不了(le)工(gong)程需要。
混(hun)凝(ning)土(tu)(tu)輸(shu)(shu)送(song)(song)泵功率、混(hun)凝(ning)土(tu)(tu)輸(shu)(shu)送(song)(song)泵出口壓力、混(hun)凝(ning)土(tu)(tu)輸(shu)(shu)送(song)(song)泵輸(shu)(shu)送(song)(song)量之(zhi)間的關系
一臺混(hun)凝土(tu)輸送(song)泵(beng)的(de)(de)電機(ji)(ji)功率(lv)是決定(ding)出口壓(ya)力和輸送(song)方量的(de)(de)前提條件,在電機(ji)(ji)功率(lv)一定(ding)的(de)(de)情況下,壓(ya)力的(de)(de)升高必將(jiang)使輸送(song)量降低(di);相反,降低(di)出口壓(ya)力,將(jiang)會使輸送(song)量增(zeng)加。
為了保證混(hun)凝土(tu)輸(shu)送(song)泵(beng)既(ji)要有較大輸(shu)送(song)量(liang),又能(neng)有一(yi)定(ding)的(de)出(chu)口(kou)(kou)壓(ya)(ya)力和與(yu)之相匹配的(de)經濟(ji)功率,在混(hun)凝土(tu)輸(shu)送(song)泵(beng)的(de)設(she)計中,大都采(cai)用了恒功率柱塞泵(beng);即(ji)恒功率值選定(ding)后,當(dang)出(chu)口(kou)(kou)壓(ya)(ya)力升高(gao)時,油(you)泵(beng)輸(shu)出(chu)排量(liang)會自動降低,達(da)到(dao)與(yu)功率設(she)計相對應的(de)值;如(ru)果既(ji)要達(da)到(dao)出(chu)口(kou)(kou)壓(ya)(ya)力高(gao),又想得到(dao)輸(shu)送(song)量(liang)大的(de)目的(de)。惟(wei)一(yi)的(de)途徑就是(shi)增加(jia)電(dian)機功率。
因此,在(zai)(zai)國(guo)家(jia)新標準中(zhong),引用了混凝土(tu)輸(shu)送(song)(song)泵(beng)的(de)(de)能力指(zhi)數(shu)概念(以MPa·m3/h為(wei)度量單位);即混凝土(tu)輸(shu)送(song)(song)泵(beng)的(de)(de)實際出(chu)口(kou)壓(ya)力與每(mei)小時實際輸(shu)送(song)(song)量之乘積,該值越大(da)(da)(da),其能力指(zhi)數(shu)也(ye)(ye)越大(da)(da)(da),電(dian)機的(de)(de)功(gong)率也(ye)(ye)將越大(da)(da)(da),由此實現大(da)(da)(da)排量、高(gao)揚程的(de)(de)目(mu)的(de)(de)。科尼樂(le)公司(si)在(zai)(zai)設(she)計時,還采(cai)用了高(gao)低壓(ya)切換的(de)(de)功(gong)能設(she)計,以滿足(zu)不同的(de)(de)施工要求,在(zai)(zai)經濟狀(zhuang)態下,又(you)能產生(sheng)較(jiao)大(da)(da)(da)的(de)(de)輸(shu)送(song)(song)量,或者以相同的(de)(de)電(dian)機功(gong)率,產生(sheng)較(jiao)高(gao)的(de)(de)出(chu)口(kou)壓(ya)力。
