37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(目前國內(nei)標準混凝土泵,37千(qian)(qian)(qian)(qian)瓦(wa)(wa)以下為細石砂漿泵)、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)(柴油(you))、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))等等。
選擇多(duo)大電機(ji)混凝土泵(beng),首先要考慮變壓(ya)器容(rong)量(liang),其次考慮距離(li)混凝土泵(beng)的遠近(jin)和線徑大小,以免(mian)壓(ya)降(jiang)過(guo)(guo)大造成(cheng)電流增高(gao)或跳閘停機(ji),過(guo)(guo)大功率造成(cheng)成(cheng)本增加和使(shi)用不便。電機(ji)過(guo)(guo)小,同時(shi)也(ye)滿(man)足不了工程(cheng)需要。
混(hun)凝(ning)(ning)土(tu)輸(shu)送(song)泵功率、混(hun)凝(ning)(ning)土(tu)輸(shu)送(song)泵出口壓力、混(hun)凝(ning)(ning)土(tu)輸(shu)送(song)泵輸(shu)送(song)量之間(jian)的關系。
一臺混(hun)凝土(tu)輸(shu)送(song)泵的電機(ji)功(gong)率是決定(ding)出(chu)口(kou)壓力(li)和(he)輸(shu)送(song)方量的前提條件,在(zai)電機(ji)功(gong)率一定(ding)的情況下,壓力(li)的升高(gao)必將使輸(shu)送(song)量降低;相反(fan),降低出(chu)口(kou)壓力(li),將會使輸(shu)送(song)量增加(jia)。
為(wei)了保(bao)證混凝(ning)土輸(shu)送(song)(song)泵(beng)既(ji)(ji)要(yao)(yao)有(you)較大(da)輸(shu)送(song)(song)量(liang)(liang),又能有(you)一定(ding)的(de)(de)出(chu)口壓(ya)力和與(yu)之相(xiang)匹配的(de)(de)經濟(ji)功(gong)率(lv)(lv),在混凝(ning)土輸(shu)送(song)(song)泵(beng)的(de)(de)設計(ji)中,大(da)都采用了恒功(gong)率(lv)(lv)柱塞泵(beng);即恒功(gong)率(lv)(lv)值選(xuan)定(ding)后,當出(chu)口壓(ya)力升高時,油(you)泵(beng)輸(shu)出(chu)排量(liang)(liang)會(hui)自動降低(di),達到與(yu)功(gong)率(lv)(lv)設計(ji)相(xiang)對(dui)應的(de)(de)值;如果既(ji)(ji)要(yao)(yao)達到出(chu)口壓(ya)力高,又想得到輸(shu)送(song)(song)量(liang)(liang)大(da)的(de)(de)目的(de)(de)。惟一的(de)(de)途徑(jing)就是(shi)增加電機(ji)功(gong)率(lv)(lv)。
因此,在(zai)(zai)國家(jia)新標準中,引用了(le)混凝土輸(shu)(shu)送泵(beng)的(de)(de)(de)(de)(de)能(neng)力(li)指數概念(以MPa·m3/h為度(du)量單位);即(ji)混凝土輸(shu)(shu)送泵(beng)的(de)(de)(de)(de)(de)實(shi)際出(chu)口(kou)壓力(li)與每小時實(shi)際輸(shu)(shu)送量之乘積,該(gai)值越大(da),其能(neng)力(li)指數也越大(da),電機的(de)(de)(de)(de)(de)功率也將(jiang)越大(da),由此實(shi)現大(da)排量、高揚程的(de)(de)(de)(de)(de)目(mu)的(de)(de)(de)(de)(de)。科尼樂(le)公司在(zai)(zai)設(she)計時,還采用了(le)高低(di)壓切換的(de)(de)(de)(de)(de)功能(neng)設(she)計,以滿足(zu)不(bu)同(tong)的(de)(de)(de)(de)(de)施工(gong)要求,在(zai)(zai)經濟狀態下,又能(neng)產生較大(da)的(de)(de)(de)(de)(de)輸(shu)(shu)送量,或者以相同(tong)的(de)(de)(de)(de)(de)電機功率,產生較高的(de)(de)(de)(de)(de)出(chu)口(kou)壓力(li)。
