37千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(目(mu)前國內標(biao)準混(hun)凝土泵,37千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)以下為細石砂漿(jiang)泵)、45千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)、55千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)、75千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)、90千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)、110千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)、130千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(柴(chai)油)、132千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)、162千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(柴(chai)油)、174千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(柴(chai)油)等(deng)等(deng)。
選(xuan)擇多(duo)大(da)(da)電機(ji)混凝土泵(beng),首(shou)先(xian)要考慮變壓(ya)器容量(liang),其次(ci)考慮距離混凝土泵(beng)的遠近和線徑大(da)(da)小,以免壓(ya)降過(guo)大(da)(da)造成(cheng)(cheng)電流(liu)增(zeng)高或跳閘停機(ji),過(guo)大(da)(da)功率造成(cheng)(cheng)成(cheng)(cheng)本增(zeng)加和使(shi)用不(bu)便(bian)。電機(ji)過(guo)小,同時(shi)也滿足(zu)不(bu)了工程(cheng)需要。
混(hun)凝土(tu)輸(shu)送(song)泵功(gong)率(lv)、混(hun)凝土(tu)輸(shu)送(song)泵出口壓力、混(hun)凝土(tu)輸(shu)送(song)泵輸(shu)送(song)量(liang)之間(jian)的關系。
一臺混凝土輸(shu)送(song)泵的(de)(de)電機(ji)功率是決定出口壓力(li)和輸(shu)送(song)方量的(de)(de)前提條件(jian),在電機(ji)功率一定的(de)(de)情況(kuang)下,壓力(li)的(de)(de)升高必將使輸(shu)送(song)量降(jiang)低;相反,降(jiang)低出口壓力(li),將會使輸(shu)送(song)量增加。
為(wei)了保證混凝土(tu)輸送泵(beng)既(ji)要有較大(da)輸送量(liang)(liang),又能(neng)有一(yi)定(ding)的(de)出(chu)口壓力和與之相匹配的(de)經濟功(gong)(gong)率(lv),在(zai)混凝土(tu)輸送泵(beng)的(de)設計中,大(da)都采用了恒(heng)功(gong)(gong)率(lv)柱塞泵(beng);即恒(heng)功(gong)(gong)率(lv)值選定(ding)后,當(dang)出(chu)口壓力升高時,油泵(beng)輸出(chu)排量(liang)(liang)會(hui)自動降低,達(da)到與功(gong)(gong)率(lv)設計相對應的(de)值;如果既(ji)要達(da)到出(chu)口壓力高,又想得到輸送量(liang)(liang)大(da)的(de)目的(de)。惟一(yi)的(de)途徑就是增加電機功(gong)(gong)率(lv)。
因此,在國(guo)家新標準(zhun)中,引用(yong)了(le)混(hun)凝土(tu)輸送泵的(de)(de)(de)能力(li)指數概念(以MPa·m3/h為度量單位(wei));即(ji)混(hun)凝土(tu)輸送泵的(de)(de)(de)實(shi)際出口壓力(li)與每小時實(shi)際輸送量之(zhi)乘(cheng)積,該值(zhi)越大(da)(da),其能力(li)指數也越大(da)(da),電機(ji)的(de)(de)(de)功率(lv)也將越大(da)(da),由此實(shi)現大(da)(da)排量、高揚(yang)程(cheng)的(de)(de)(de)目的(de)(de)(de)。科尼樂公(gong)司在設(she)計時,還采用(yong)了(le)高低壓切(qie)換(huan)的(de)(de)(de)功能設(she)計,以滿足(zu)不同的(de)(de)(de)施工要求,在經濟狀態下,又能產生(sheng)較(jiao)大(da)(da)的(de)(de)(de)輸送量,或者以相同的(de)(de)(de)電機(ji)功率(lv),產生(sheng)較(jiao)高的(de)(de)(de)出口壓力(li)。
