隨著現代工(gong)(gong)業(ye)的(de)興起,以混(hun)(hun)凝(ning)土為主材料的(de)建設方式已經(jing)成為了(le)建筑業(ye)施(shi)工(gong)(gong)的(de)主要構造之(zhi)一(yi),在各(ge)種工(gong)(gong)程施(shi)工(gong)(gong)建設中占據了(le)很大的(de)比例(li),使(shi)得混(hun)(hun)凝(ning)土機械的(de)發(fa)展經(jing)久不衰,且有越演越烈(lie)的(de)形(xing)勢。拖式混(hun)(hun)凝(ning)土泵(beng)(beng),簡稱拖泵(beng)(beng),是各(ge)種混(hun)(hun)凝(ning)土機械中的(de)一(yi)種,用(yong)于混(hun)(hun)凝(ning)土施(shi)工(gong)(gong)中的(de)輸送和澆(jiao)注工(gong)(gong)作。
拖泵分類選(xuan)型(xing)
37千(qian)(qian)(qian)瓦(wa)(wa)(目前國內標準混凝土泵,37千(qian)(qian)(qian)瓦(wa)(wa)以(yi)下(xia)為細石砂(sha)漿泵)、45千(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))、132千(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))、174千(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))等。
選擇多大電機(ji)混(hun)凝土泵,首先要考慮(lv)變壓器(qi)容量,其次考慮(lv)距離(li)混(hun)凝土泵的(de)遠近(jin)和(he)線徑大小,以免壓降過(guo)(guo)大造成電流(liu)增高或跳閘停機(ji),過(guo)(guo)大功率造成成本增加和(he)使(shi)用不便。電機(ji)過(guo)(guo)小,同時也滿足不了工程需要。
混(hun)(hun)凝(ning)土輸(shu)(shu)送泵功率、混(hun)(hun)凝(ning)土輸(shu)(shu)送泵出口壓力(li)、混(hun)(hun)凝(ning)土輸(shu)(shu)送泵輸(shu)(shu)送量之間的關系
一(yi)臺混凝土輸(shu)送(song)(song)(song)泵的(de)(de)電機功率是決定出口(kou)壓(ya)力和(he)輸(shu)送(song)(song)(song)方量(liang)的(de)(de)前提條件,在電機功率一(yi)定的(de)(de)情況下,壓(ya)力的(de)(de)升(sheng)高必將(jiang)使輸(shu)送(song)(song)(song)量(liang)降(jiang)低;相反,降(jiang)低出口(kou)壓(ya)力,將(jiang)會使輸(shu)送(song)(song)(song)量(liang)增(zeng)加。
為了保證(zheng)混凝土輸(shu)(shu)送(song)(song)(song)泵既要(yao)有較大輸(shu)(shu)送(song)(song)(song)量(liang),又能有一定的(de)(de)出口壓力和(he)與之相(xiang)匹配(pei)的(de)(de)經濟功(gong)(gong)率(lv),在混凝土輸(shu)(shu)送(song)(song)(song)泵的(de)(de)設計(ji)(ji)中,大都采用了恒功(gong)(gong)率(lv)柱塞泵;即(ji)恒功(gong)(gong)率(lv)值(zhi)選定后,當出口壓力升高(gao)時,油泵輸(shu)(shu)出排量(liang)會自動(dong)降低(di),達到(dao)與功(gong)(gong)率(lv)設計(ji)(ji)相(xiang)對(dui)應的(de)(de)值(zhi);如果既要(yao)達到(dao)出口壓力高(gao),又想得到(dao)輸(shu)(shu)送(song)(song)(song)量(liang)大的(de)(de)目的(de)(de)。惟一的(de)(de)途(tu)徑就是(shi)增加(jia)電機(ji)功(gong)(gong)率(lv)。
因此,在(zai)國家新標準(zhun)中,引用了混凝(ning)土輸(shu)送(song)(song)泵的(de)(de)(de)(de)能力(li)指數(shu)概念(nian)(以MPa·m3/h為度(du)量單(dan)位);即混凝(ning)土輸(shu)送(song)(song)泵的(de)(de)(de)(de)實際出口(kou)壓(ya)力(li)與每小時(shi)實際輸(shu)送(song)(song)量之乘積,該值越大(da),其能力(li)指數(shu)也(ye)越大(da),電機的(de)(de)(de)(de)功(gong)率也(ye)將越大(da),由(you)此實現大(da)排(pai)量、高(gao)揚程的(de)(de)(de)(de)目(mu)的(de)(de)(de)(de)。科尼樂公司在(zai)設(she)(she)計時(shi),還采用了高(gao)低壓(ya)切換的(de)(de)(de)(de)功(gong)能設(she)(she)計,以滿足不同的(de)(de)(de)(de)施(shi)工(gong)要求,在(zai)經濟狀(zhuang)態下,又能產(chan)生較(jiao)(jiao)大(da)的(de)(de)(de)(de)輸(shu)送(song)(song)量,或者以相同的(de)(de)(de)(de)電機功(gong)率,產(chan)生較(jiao)(jiao)高(gao)的(de)(de)(de)(de)出口(kou)壓(ya)力(li)。
