37千(qian)(qian)瓦(wa)(wa)(wa)(目前國內標準混(hun)凝(ning)土泵,37千(qian)(qian)瓦(wa)(wa)(wa)以下(xia)為細石(shi)砂漿泵)、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(xuan)擇(ze)多大(da)電(dian)(dian)機混凝(ning)土泵,首先要(yao)考慮變壓器容(rong)量,其次考慮距離混凝(ning)土泵的(de)遠近和(he)線徑大(da)小,以免(mian)壓降過(guo)大(da)造成(cheng)電(dian)(dian)流增高或(huo)跳(tiao)閘停機,過(guo)大(da)功率造成(cheng)成(cheng)本增加(jia)和(he)使用不(bu)便。電(dian)(dian)機過(guo)小,同時也滿(man)足不(bu)了工程需要(yao)。
混(hun)(hun)凝土輸(shu)送(song)(song)泵(beng)功率、混(hun)(hun)凝土輸(shu)送(song)(song)泵(beng)出(chu)口壓力、混(hun)(hun)凝土輸(shu)送(song)(song)泵(beng)輸(shu)送(song)(song)量(liang)之(zhi)間(jian)的關系。
一臺(tai)混凝土輸送(song)泵的(de)電機(ji)功率(lv)是決(jue)定(ding)出(chu)口壓(ya)(ya)力(li)和輸送(song)方(fang)量(liang)的(de)前提條件,在(zai)電機(ji)功率(lv)一定(ding)的(de)情況下,壓(ya)(ya)力(li)的(de)升高必將(jiang)(jiang)使輸送(song)量(liang)降(jiang)低(di);相反,降(jiang)低(di)出(chu)口壓(ya)(ya)力(li),將(jiang)(jiang)會使輸送(song)量(liang)增加。
為(wei)了保證混(hun)凝土(tu)輸送(song)(song)泵(beng)(beng)既要有(you)較大輸送(song)(song)量,又能(neng)有(you)一定的(de)(de)出(chu)(chu)口壓(ya)力(li)和與之相匹配的(de)(de)經濟功(gong)率(lv),在混(hun)凝土(tu)輸送(song)(song)泵(beng)(beng)的(de)(de)設計(ji)中,大都采(cai)用了恒(heng)功(gong)率(lv)柱塞泵(beng)(beng);即恒(heng)功(gong)率(lv)值(zhi)選定后(hou),當出(chu)(chu)口壓(ya)力(li)升高時,油泵(beng)(beng)輸出(chu)(chu)排量會自動降低,達到與功(gong)率(lv)設計(ji)相對(dui)應的(de)(de)值(zhi);如果既要達到出(chu)(chu)口壓(ya)力(li)高,又想得(de)到輸送(song)(song)量大的(de)(de)目的(de)(de)。惟一的(de)(de)途(tu)徑就(jiu)是增加電機功(gong)率(lv)。
因此,在(zai)國家(jia)新標準中,引用了混凝土輸(shu)(shu)送(song)(song)(song)泵的(de)(de)能力指數概念(nian)(以MPa·m3/h為度量單(dan)位);即(ji)混凝土輸(shu)(shu)送(song)(song)(song)泵的(de)(de)實(shi)際(ji)出口壓力與每小時實(shi)際(ji)輸(shu)(shu)送(song)(song)(song)量之乘積,該值(zhi)越(yue)大(da)(da),其(qi)能力指數也越(yue)大(da)(da),電機的(de)(de)功率也將越(yue)大(da)(da),由此實(shi)現(xian)大(da)(da)排(pai)量、高揚程的(de)(de)目的(de)(de)。科尼樂公(gong)司在(zai)設(she)計時,還采用了高低壓切換的(de)(de)功能設(she)計,以滿足不同的(de)(de)施工要(yao)求,在(zai)經濟狀態下,又(you)能產生(sheng)較(jiao)大(da)(da)的(de)(de)輸(shu)(shu)送(song)(song)(song)量,或者以相同的(de)(de)電機功率,產生(sheng)較(jiao)高的(de)(de)出口壓力。
