37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(目前(qian)國內標準混凝土泵(beng),37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)以下(xia)為細(xi)石砂漿泵(beng))、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴油)、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴油)、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴油)等等。
選擇多大電機(ji)混凝土泵,首先要考(kao)(kao)慮(lv)變(bian)壓器容量(liang),其(qi)次考(kao)(kao)慮(lv)距離混凝土泵的遠近和線徑(jing)大小,以免壓降過大造成(cheng)電流增(zeng)高(gao)或跳閘停機(ji),過大功率造成(cheng)成(cheng)本增(zeng)加和使用(yong)不(bu)便。電機(ji)過小,同時也滿足不(bu)了工程需要。
混(hun)凝土輸送(song)(song)泵功率、混(hun)凝土輸送(song)(song)泵出口壓(ya)力、混(hun)凝土輸送(song)(song)泵輸送(song)(song)量之間的關系
一臺混凝土輸(shu)送(song)泵的(de)電機功(gong)率是(shi)決定出(chu)口壓(ya)力(li)和(he)輸(shu)送(song)方量的(de)前提條(tiao)件,在電機功(gong)率一定的(de)情況下,壓(ya)力(li)的(de)升高必將(jiang)使(shi)輸(shu)送(song)量降(jiang)低(di)(di);相反(fan),降(jiang)低(di)(di)出(chu)口壓(ya)力(li),將(jiang)會(hui)使(shi)輸(shu)送(song)量增加。
為(wei)了(le)保證混凝土輸(shu)送泵既要有較大輸(shu)送量(liang)(liang)(liang),又能有一定(ding)的(de)(de)(de)(de)出口壓力和與之相匹(pi)配的(de)(de)(de)(de)經濟功(gong)(gong)(gong)率,在混凝土輸(shu)送泵的(de)(de)(de)(de)設計中,大都采用了(le)恒功(gong)(gong)(gong)率柱塞泵;即恒功(gong)(gong)(gong)率值選定(ding)后,當出口壓力升高時,油泵輸(shu)出排(pai)量(liang)(liang)(liang)會自動降(jiang)低,達(da)到與功(gong)(gong)(gong)率設計相對應的(de)(de)(de)(de)值;如果既要達(da)到出口壓力高,又想得到輸(shu)送量(liang)(liang)(liang)大的(de)(de)(de)(de)目的(de)(de)(de)(de)。惟一的(de)(de)(de)(de)途徑(jing)就是增(zeng)加電機功(gong)(gong)(gong)率。
因(yin)此(ci),在國(guo)家(jia)新標準中,引用(yong)了混凝土輸(shu)送(song)泵的(de)(de)能(neng)力指(zhi)數概念(以(yi)(yi)MPa·m3/h為度量單(dan)位(wei));即混凝土輸(shu)送(song)泵的(de)(de)實際(ji)出(chu)口壓力與每小時實際(ji)輸(shu)送(song)量之乘積,該值(zhi)越大(da),其能(neng)力指(zhi)數也越大(da),電機(ji)的(de)(de)功(gong)率也將越大(da),由此(ci)實現大(da)排量、高揚程的(de)(de)目的(de)(de)。科尼樂公司(si)在設計時,還采用(yong)了高低壓切(qie)換的(de)(de)功(gong)能(neng)設計,以(yi)(yi)滿足不同的(de)(de)施(shi)工要求,在經(jing)濟狀態下,又(you)能(neng)產生較大(da)的(de)(de)輸(shu)送(song)量,或者(zhe)以(yi)(yi)相同的(de)(de)電機(ji)功(gong)率,產生較高的(de)(de)出(chu)口壓力。
