37千(qian)(qian)(qian)瓦(wa)(wa)(目前國(guo)內(nei)標準混(hun)凝土泵,37千(qian)(qian)(qian)瓦(wa)(wa)以(yi)下為細石砂漿泵)、45千(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))、132千(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))、174千(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))等等。
選擇多大(da)電機混(hun)凝(ning)土泵(beng),首先要(yao)考(kao)慮變(bian)壓器容量,其次考(kao)慮距離混(hun)凝(ning)土泵(beng)的遠近和線徑大(da)小(xiao),以免壓降過(guo)大(da)造成(cheng)電流增(zeng)高或跳閘停(ting)機,過(guo)大(da)功率造成(cheng)成(cheng)本增(zeng)加(jia)和使用不(bu)便(bian)。電機過(guo)小(xiao),同時也滿足不(bu)了工程需要(yao)。
混凝(ning)土(tu)輸(shu)(shu)送(song)泵功率、混凝(ning)土(tu)輸(shu)(shu)送(song)泵出口壓力、混凝(ning)土(tu)輸(shu)(shu)送(song)泵輸(shu)(shu)送(song)量(liang)之間的(de)關系。
一臺混凝土(tu)輸(shu)送(song)泵的電機功率是決定(ding)出口(kou)(kou)壓力(li)和(he)輸(shu)送(song)方量(liang)的前提條件,在電機功率一定(ding)的情況下,壓力(li)的升高必將使(shi)輸(shu)送(song)量(liang)降(jiang)低;相反,降(jiang)低出口(kou)(kou)壓力(li),將會使(shi)輸(shu)送(song)量(liang)增加。
為(wei)了保證混(hun)凝(ning)土輸(shu)(shu)(shu)送(song)泵既(ji)要有(you)(you)較大(da)輸(shu)(shu)(shu)送(song)量,又(you)(you)能有(you)(you)一(yi)(yi)定的(de)(de)出(chu)口(kou)壓(ya)力和與之相匹配的(de)(de)經濟功(gong)(gong)率(lv),在混(hun)凝(ning)土輸(shu)(shu)(shu)送(song)泵的(de)(de)設計中,大(da)都采用了恒功(gong)(gong)率(lv)柱塞泵;即(ji)恒功(gong)(gong)率(lv)值(zhi)選(xuan)定后,當(dang)出(chu)口(kou)壓(ya)力升高(gao)時(shi),油泵輸(shu)(shu)(shu)出(chu)排量會(hui)自(zi)動降(jiang)低,達(da)到與功(gong)(gong)率(lv)設計相對應(ying)的(de)(de)值(zhi);如果既(ji)要達(da)到出(chu)口(kou)壓(ya)力高(gao),又(you)(you)想(xiang)得到輸(shu)(shu)(shu)送(song)量大(da)的(de)(de)目的(de)(de)。惟一(yi)(yi)的(de)(de)途(tu)徑(jing)就是增(zeng)加電機(ji)功(gong)(gong)率(lv)。
因(yin)此,在國家新標準中,引用(yong)(yong)了(le)混凝土輸(shu)送(song)泵的(de)能力指(zhi)數(shu)(shu)概念(nian)(以MPa·m3/h為度量(liang)(liang)(liang)單位);即(ji)混凝土輸(shu)送(song)泵的(de)實(shi)際(ji)出(chu)口(kou)壓力與每小(xiao)時實(shi)際(ji)輸(shu)送(song)量(liang)(liang)(liang)之乘(cheng)積(ji),該值越大(da),其能力指(zhi)數(shu)(shu)也越大(da),電機(ji)的(de)功率也將越大(da),由此實(shi)現大(da)排量(liang)(liang)(liang)、高(gao)揚程的(de)目的(de)。科尼樂公(gong)司(si)在設(she)(she)計時,還采(cai)用(yong)(yong)了(le)高(gao)低壓切換(huan)的(de)功能設(she)(she)計,以滿足不同(tong)的(de)施工要(yao)求,在經濟狀態(tai)下,又能產(chan)生較大(da)的(de)輸(shu)送(song)量(liang)(liang)(liang),或(huo)者以相同(tong)的(de)電機(ji)功率,產(chan)生較高(gao)的(de)出(chu)口(kou)壓力。
