37千(qian)(qian)(qian)(qian)瓦(wa)(目前國內標準(zhun)混凝土泵,37千(qian)(qian)(qian)(qian)瓦(wa)以下為(wei)細(xi)石砂漿(jiang)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)(柴油(you))、132千(qian)(qian)(qian)(qian)瓦(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(柴油(you))、174千(qian)(qian)(qian)(qian)瓦(wa)(柴油(you))等等。
選擇多大(da)電機(ji)混凝(ning)(ning)土泵,首先要考慮變壓器(qi)容量,其次(ci)考慮距離混凝(ning)(ning)土泵的遠近和(he)線徑大(da)小,以免壓降過大(da)造成電流增高或跳閘停機(ji),過大(da)功(gong)率造成成本增加和(he)使用(yong)不便。電機(ji)過小,同時也滿足不了工程需要。
混凝(ning)土(tu)輸送(song)泵(beng)功(gong)率、混凝(ning)土(tu)輸送(song)泵(beng)出口壓力、混凝(ning)土(tu)輸送(song)泵(beng)輸送(song)量(liang)之間的關系。
一臺(tai)混凝土輸(shu)送(song)(song)泵的(de)電機(ji)功(gong)率是(shi)決(jue)定出口壓(ya)(ya)力(li)和輸(shu)送(song)(song)方量的(de)前(qian)提條件,在電機(ji)功(gong)率一定的(de)情(qing)況下,壓(ya)(ya)力(li)的(de)升高必將(jiang)使輸(shu)送(song)(song)量降低;相反,降低出口壓(ya)(ya)力(li),將(jiang)會使輸(shu)送(song)(song)量增加(jia)。
為了(le)保證(zheng)混凝土(tu)輸(shu)(shu)(shu)送(song)泵(beng)既要有(you)較大(da)輸(shu)(shu)(shu)送(song)量(liang),又能(neng)有(you)一(yi)定的(de)(de)出口(kou)壓力和與之相匹配的(de)(de)經濟功(gong)(gong)率(lv),在(zai)混凝土(tu)輸(shu)(shu)(shu)送(song)泵(beng)的(de)(de)設計中,大(da)都采用了(le)恒功(gong)(gong)率(lv)柱塞泵(beng);即恒功(gong)(gong)率(lv)值選定后,當出口(kou)壓力升(sheng)高(gao)時,油泵(beng)輸(shu)(shu)(shu)出排量(liang)會自動降低(di),達到與功(gong)(gong)率(lv)設計相對應的(de)(de)值;如果既要達到出口(kou)壓力高(gao),又想得(de)到輸(shu)(shu)(shu)送(song)量(liang)大(da)的(de)(de)目的(de)(de)。惟一(yi)的(de)(de)途徑就是(shi)增加電機(ji)功(gong)(gong)率(lv)。
因(yin)此(ci),在(zai)(zai)國家新標準中(zhong),引(yin)用了混凝土(tu)輸送(song)泵(beng)的(de)能(neng)力(li)指數概念(以(yi)MPa·m3/h為度量(liang)單位(wei));即混凝土(tu)輸送(song)泵(beng)的(de)實(shi)際出口(kou)壓(ya)(ya)力(li)與每小時實(shi)際輸送(song)量(liang)之乘積,該(gai)值越大(da)(da),其(qi)能(neng)力(li)指數也(ye)越大(da)(da),電(dian)機(ji)的(de)功(gong)率也(ye)將越大(da)(da),由此(ci)實(shi)現大(da)(da)排(pai)量(liang)、高(gao)(gao)揚程的(de)目的(de)。科尼樂公(gong)司(si)在(zai)(zai)設計時,還采用了高(gao)(gao)低壓(ya)(ya)切換的(de)功(gong)能(neng)設計,以(yi)滿足不同(tong)(tong)的(de)施工要求,在(zai)(zai)經濟(ji)狀(zhuang)態下,又能(neng)產(chan)生(sheng)(sheng)較大(da)(da)的(de)輸送(song)量(liang),或(huo)者(zhe)以(yi)相同(tong)(tong)的(de)電(dian)機(ji)功(gong)率,產(chan)生(sheng)(sheng)較高(gao)(gao)的(de)出口(kou)壓(ya)(ya)力(li)。
