37千(qian)(qian)瓦(wa)(wa)(目(mu)前(qian)國內標準混凝土泵(beng),37千(qian)(qian)瓦(wa)(wa)以(yi)下為細(xi)石(shi)砂漿泵(beng))、45千(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)瓦(wa)(wa)(柴(chai)油(you))、132千(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)瓦(wa)(wa)(柴(chai)油(you))、174千(qian)(qian)瓦(wa)(wa)(柴(chai)油(you))等(deng)等(deng)。
選擇多大(da)電機(ji)混凝土(tu)(tu)泵,首先要考慮變壓(ya)器容量(liang),其次考慮距離混凝土(tu)(tu)泵的遠近和線(xian)徑大(da)小,以免壓(ya)降(jiang)過(guo)大(da)造(zao)成(cheng)電流增(zeng)高或跳閘(zha)停機(ji),過(guo)大(da)功率造(zao)成(cheng)成(cheng)本增(zeng)加和使用不(bu)便。電機(ji)過(guo)小,同時也滿足不(bu)了工程需(xu)要。
混(hun)(hun)凝(ning)土輸(shu)(shu)送(song)泵(beng)功率、混(hun)(hun)凝(ning)土輸(shu)(shu)送(song)泵(beng)出口壓力、混(hun)(hun)凝(ning)土輸(shu)(shu)送(song)泵(beng)輸(shu)(shu)送(song)量之(zhi)間的關(guan)系
一臺混凝土輸送(song)泵的(de)電(dian)機(ji)功率(lv)是決定出口壓力和輸送(song)方量的(de)前提(ti)條件,在電(dian)機(ji)功率(lv)一定的(de)情況下,壓力的(de)升高必將(jiang)使輸送(song)量降低;相反,降低出口壓力,將(jiang)會(hui)使輸送(song)量增加。
為了保證混(hun)凝土輸(shu)送(song)(song)泵(beng)(beng)既(ji)要有(you)較(jiao)大(da)(da)輸(shu)送(song)(song)量,又(you)能有(you)一定(ding)的(de)出(chu)(chu)口(kou)壓力和與之相匹(pi)配的(de)經濟功(gong)(gong)率,在混(hun)凝土輸(shu)送(song)(song)泵(beng)(beng)的(de)設(she)計(ji)中,大(da)(da)都采(cai)用了恒功(gong)(gong)率柱塞泵(beng)(beng);即恒功(gong)(gong)率值(zhi)選定(ding)后,當出(chu)(chu)口(kou)壓力升高(gao)時,油泵(beng)(beng)輸(shu)出(chu)(chu)排(pai)量會自動降低,達到(dao)與功(gong)(gong)率設(she)計(ji)相對(dui)應(ying)的(de)值(zhi);如果既(ji)要達到(dao)出(chu)(chu)口(kou)壓力高(gao),又(you)想得到(dao)輸(shu)送(song)(song)量大(da)(da)的(de)目(mu)的(de)。惟一的(de)途徑就是增加電機功(gong)(gong)率。
因此,在國家新標準中,引用了混(hun)凝土(tu)輸(shu)送(song)(song)泵(beng)的(de)能(neng)(neng)力(li)指(zhi)數概(gai)念(以MPa·m3/h為度量(liang)單位(wei));即混(hun)凝土(tu)輸(shu)送(song)(song)泵(beng)的(de)實際出(chu)口壓(ya)力(li)與每小時實際輸(shu)送(song)(song)量(liang)之乘(cheng)積(ji),該值越(yue)大(da)(da)(da),其能(neng)(neng)力(li)指(zhi)數也越(yue)大(da)(da)(da),電(dian)(dian)機的(de)功(gong)率也將越(yue)大(da)(da)(da),由此實現大(da)(da)(da)排量(liang)、高揚(yang)程的(de)目(mu)的(de)。科尼樂(le)公司在設計時,還采用了高低壓(ya)切換的(de)功(gong)能(neng)(neng)設計,以滿足不同(tong)(tong)的(de)施工要(yao)求,在經濟狀態下,又能(neng)(neng)產(chan)生較(jiao)大(da)(da)(da)的(de)輸(shu)送(song)(song)量(liang),或者以相同(tong)(tong)的(de)電(dian)(dian)機功(gong)率,產(chan)生較(jiao)高的(de)出(chu)口壓(ya)力(li)。
