37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(目前國內標準(zhun)混凝土泵,37千(qian)(qian)(qian)(qian)瓦(wa)(wa)以下為細(xi)石砂漿泵)、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)(chai)(chai)油(you))、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)(chai)(chai)油(you))、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)(chai)(chai)油(you))等等。
選擇多大(da)(da)電機(ji)混凝(ning)土泵,首先要考慮變壓器容量,其(qi)次考慮距離混凝(ning)土泵的遠近和線徑大(da)(da)小,以免(mian)壓降過(guo)大(da)(da)造成(cheng)(cheng)電流增(zeng)高(gao)或跳閘停機(ji),過(guo)大(da)(da)功率造成(cheng)(cheng)成(cheng)(cheng)本增(zeng)加和使(shi)用不(bu)便。電機(ji)過(guo)小,同時也滿(man)足不(bu)了工程需(xu)要。
混(hun)凝土輸(shu)送(song)泵(beng)功率、混(hun)凝土輸(shu)送(song)泵(beng)出口壓(ya)力、混(hun)凝土輸(shu)送(song)泵(beng)輸(shu)送(song)量之(zhi)間的關(guan)系
一(yi)臺混(hun)凝土輸送(song)(song)(song)(song)泵的(de)電機功率是決定出(chu)口壓(ya)(ya)力和輸送(song)(song)(song)(song)方量的(de)前提(ti)條件,在(zai)電機功率一(yi)定的(de)情(qing)況(kuang)下(xia),壓(ya)(ya)力的(de)升高必將(jiang)使輸送(song)(song)(song)(song)量降低;相反,降低出(chu)口壓(ya)(ya)力,將(jiang)會使輸送(song)(song)(song)(song)量增加。
為了保證混凝土輸送泵既(ji)要有較大(da)輸送量,又能(neng)有一定的出(chu)口(kou)(kou)壓(ya)力(li)和與(yu)之相匹配的經濟功(gong)率(lv)(lv),在混凝土輸送泵的設(she)計(ji)中(zhong),大(da)都采用(yong)了恒功(gong)率(lv)(lv)柱塞泵;即(ji)恒功(gong)率(lv)(lv)值選定后,當出(chu)口(kou)(kou)壓(ya)力(li)升(sheng)高時,油(you)泵輸出(chu)排量會自動降低(di),達到與(yu)功(gong)率(lv)(lv)設(she)計(ji)相對應的值;如果既(ji)要達到出(chu)口(kou)(kou)壓(ya)力(li)高,又想得(de)到輸送量大(da)的目的。惟一的途徑就是增加電機功(gong)率(lv)(lv)。
因(yin)此(ci),在國家新(xin)標(biao)準中,引(yin)用了混凝土輸送(song)(song)泵(beng)的(de)(de)(de)(de)能力指數概念(以MPa·m3/h為度量單(dan)位);即混凝土輸送(song)(song)泵(beng)的(de)(de)(de)(de)實(shi)際出口壓(ya)力與(yu)每小時(shi)實(shi)際輸送(song)(song)量之(zhi)乘(cheng)積,該值(zhi)越(yue)大(da)(da)(da)(da),其能力指數也(ye)越(yue)大(da)(da)(da)(da),電(dian)機的(de)(de)(de)(de)功率也(ye)將越(yue)大(da)(da)(da)(da),由此(ci)實(shi)現大(da)(da)(da)(da)排量、高揚程(cheng)的(de)(de)(de)(de)目的(de)(de)(de)(de)。科尼樂(le)公司(si)在設(she)計(ji)(ji)時(shi),還采(cai)用了高低壓(ya)切換的(de)(de)(de)(de)功能設(she)計(ji)(ji),以滿足(zu)不同的(de)(de)(de)(de)施工要求,在經濟狀態下(xia),又能產(chan)生(sheng)較(jiao)大(da)(da)(da)(da)的(de)(de)(de)(de)輸送(song)(song)量,或者以相同的(de)(de)(de)(de)電(dian)機功率,產(chan)生(sheng)較(jiao)高的(de)(de)(de)(de)出口壓(ya)力。
