37千(qian)(qian)(qian)(qian)瓦(wa)(目(mu)前國內標準混凝(ning)土泵,37千(qian)(qian)(qian)(qian)瓦(wa)以下為細石砂漿泵)、45千(qian)(qian)(qian)(qian)瓦(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(柴(chai)油)、132千(qian)(qian)(qian)(qian)瓦(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(柴(chai)油)、174千(qian)(qian)(qian)(qian)瓦(wa)(柴(chai)油)等等。
選(xuan)擇多大(da)電機混(hun)凝土泵,首先要考(kao)慮(lv)變壓器容量,其次考(kao)慮(lv)距離混(hun)凝土泵的遠(yuan)近(jin)和(he)線(xian)徑大(da)小,以(yi)免壓降(jiang)過大(da)造成(cheng)電流增(zeng)高(gao)或跳(tiao)閘停機,過大(da)功率造成(cheng)成(cheng)本增(zeng)加和(he)使用不(bu)便。電機過小,同(tong)時也滿足不(bu)了工程需要。
混(hun)凝(ning)土輸(shu)送(song)(song)(song)泵(beng)功(gong)率、混(hun)凝(ning)土輸(shu)送(song)(song)(song)泵(beng)出口壓力、混(hun)凝(ning)土輸(shu)送(song)(song)(song)泵(beng)輸(shu)送(song)(song)(song)量之間(jian)的關系
一(yi)臺混凝土輸送(song)(song)泵的(de)(de)電機功率是決定出(chu)口壓(ya)(ya)力和輸送(song)(song)方量(liang)的(de)(de)前提(ti)條件,在電機功率一(yi)定的(de)(de)情況下,壓(ya)(ya)力的(de)(de)升高必將(jiang)使輸送(song)(song)量(liang)降(jiang)低(di)(di);相反,降(jiang)低(di)(di)出(chu)口壓(ya)(ya)力,將(jiang)會使輸送(song)(song)量(liang)增加。
為了(le)保(bao)證混凝(ning)土輸(shu)(shu)(shu)送(song)泵既(ji)要(yao)(yao)有較(jiao)大輸(shu)(shu)(shu)送(song)量(liang),又(you)能有一(yi)定的出口(kou)壓(ya)力(li)和與(yu)之相(xiang)匹配的經濟(ji)功率(lv)(lv),在混凝(ning)土輸(shu)(shu)(shu)送(song)泵的設計(ji)中,大都(dou)采用了(le)恒功率(lv)(lv)柱(zhu)塞泵;即(ji)恒功率(lv)(lv)值選定后,當(dang)出口(kou)壓(ya)力(li)升高時,油泵輸(shu)(shu)(shu)出排(pai)量(liang)會自(zi)動(dong)降低,達到(dao)(dao)與(yu)功率(lv)(lv)設計(ji)相(xiang)對應的值;如(ru)果既(ji)要(yao)(yao)達到(dao)(dao)出口(kou)壓(ya)力(li)高,又(you)想得到(dao)(dao)輸(shu)(shu)(shu)送(song)量(liang)大的目的。惟一(yi)的途徑就是增加電機(ji)功率(lv)(lv)。
因此(ci),在國家新標(biao)準(zhun)中,引用(yong)了混(hun)凝土輸(shu)送(song)泵的(de)(de)能力(li)指(zhi)數(shu)概念(以(yi)MPa·m3/h為度量單位(wei));即混(hun)凝土輸(shu)送(song)泵的(de)(de)實際(ji)(ji)出口壓力(li)與每小(xiao)時實際(ji)(ji)輸(shu)送(song)量之乘積,該值越(yue)大,其能力(li)指(zhi)數(shu)也越(yue)大,電機的(de)(de)功率(lv)也將越(yue)大,由此(ci)實現大排量、高揚程的(de)(de)目的(de)(de)。科尼樂公(gong)司在設計(ji)時,還采用(yong)了高低壓切換(huan)的(de)(de)功能設計(ji),以(yi)滿足(zu)不同的(de)(de)施工要(yao)求(qiu),在經濟狀態(tai)下,又(you)能產生較(jiao)大的(de)(de)輸(shu)送(song)量,或者以(yi)相同的(de)(de)電機功率(lv),產生較(jiao)高的(de)(de)出口壓力(li)。
