37千(qian)(qian)瓦(wa)(wa)(wa)(目(mu)前(qian)國內(nei)標(biao)準混凝(ning)土泵(beng),37千(qian)(qian)瓦(wa)(wa)(wa)以下為細(xi)石砂漿泵(beng))、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)(柴油)、132千(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)瓦(wa)(wa)(wa)(柴油)、174千(qian)(qian)瓦(wa)(wa)(wa)(柴油)等等。
選擇多(duo)大(da)電(dian)機(ji)混(hun)凝土泵(beng),首(shou)先要考慮變壓(ya)器容量,其次考慮距離混(hun)凝土泵(beng)的遠近和線徑大(da)小,以免壓(ya)降(jiang)過(guo)大(da)造成(cheng)電(dian)流增(zeng)高或跳閘停機(ji),過(guo)大(da)功率造成(cheng)成(cheng)本(ben)增(zeng)加(jia)和使用不便。電(dian)機(ji)過(guo)小,同(tong)時也滿足不了工程需(xu)要。
混(hun)凝土(tu)輸送泵(beng)功(gong)率、混(hun)凝土(tu)輸送泵(beng)出口壓(ya)力、混(hun)凝土(tu)輸送泵(beng)輸送量之間的關(guan)系。
一臺混凝土輸(shu)送(song)(song)泵的電機(ji)功率(lv)是決(jue)定出(chu)(chu)口壓力和輸(shu)送(song)(song)方量的前提條件(jian),在電機(ji)功率(lv)一定的情(qing)況下,壓力的升高必將(jiang)使輸(shu)送(song)(song)量降低;相(xiang)反(fan),降低出(chu)(chu)口壓力,將(jiang)會使輸(shu)送(song)(song)量增加(jia)。
為(wei)了保證混(hun)凝土(tu)輸(shu)送(song)泵(beng)(beng)既(ji)要有較大(da)(da)輸(shu)送(song)量(liang),又能(neng)有一定的出(chu)口壓(ya)(ya)力(li)和與之相匹配的經濟功(gong)率,在混(hun)凝土(tu)輸(shu)送(song)泵(beng)(beng)的設計中(zhong),大(da)(da)都采用了恒功(gong)率柱塞泵(beng)(beng);即恒功(gong)率值選定后,當出(chu)口壓(ya)(ya)力(li)升高(gao)時,油泵(beng)(beng)輸(shu)出(chu)排(pai)量(liang)會(hui)自動降(jiang)低,達(da)(da)到與功(gong)率設計相對應的值;如果既(ji)要達(da)(da)到出(chu)口壓(ya)(ya)力(li)高(gao),又想得到輸(shu)送(song)量(liang)大(da)(da)的目的。惟(wei)一的途徑就是增加電機(ji)功(gong)率。
因此(ci),在國家新標準中,引用了混凝土輸(shu)送(song)(song)(song)泵的(de)能(neng)力指(zhi)數概念(以MPa·m3/h為度(du)量(liang)單位);即混凝土輸(shu)送(song)(song)(song)泵的(de)實(shi)際出口壓(ya)力與每小時實(shi)際輸(shu)送(song)(song)(song)量(liang)之乘積(ji),該(gai)值(zhi)越(yue)大(da)(da)(da),其(qi)能(neng)力指(zhi)數也越(yue)大(da)(da)(da),電機的(de)功(gong)(gong)率也將越(yue)大(da)(da)(da),由此(ci)實(shi)現大(da)(da)(da)排量(liang)、高(gao)揚程的(de)目的(de)。科(ke)尼(ni)樂公司在設計時,還采用了高(gao)低壓(ya)切換的(de)功(gong)(gong)能(neng)設計,以滿足(zu)不同(tong)(tong)的(de)施工要求,在經濟(ji)狀(zhuang)態(tai)下,又能(neng)產生(sheng)(sheng)較大(da)(da)(da)的(de)輸(shu)送(song)(song)(song)量(liang),或者以相同(tong)(tong)的(de)電機功(gong)(gong)率,產生(sheng)(sheng)較高(gao)的(de)出口壓(ya)力。
