具體參數
隨(sui)著現代工(gong)業(ye)的(de)興起,以混(hun)(hun)凝(ning)(ning)土為主材料的(de)建(jian)設(she)方式(shi)已經成為了建(jian)筑(zhu)業(ye)施(shi)(shi)工(gong)的(de)主要構造之一,在各種(zhong)工(gong)程施(shi)(shi)工(gong)建(jian)設(she)中(zhong)(zhong)占據了很大(da)的(de)比(bi)例,使得混(hun)(hun)凝(ning)(ning)土機(ji)械的(de)發展經久不衰(shuai),且(qie)有越演越烈的(de)形勢(shi)。拖(tuo)(tuo)式(shi)混(hun)(hun)凝(ning)(ning)土泵,簡(jian)稱拖(tuo)(tuo)泵,是各種(zhong)混(hun)(hun)凝(ning)(ning)土機(ji)械中(zhong)(zhong)的(de)一種(zhong),用于混(hun)(hun)凝(ning)(ning)土施(shi)(shi)工(gong)中(zhong)(zhong)的(de)輸送(song)和(he)澆(jiao)注(zhu)工(gong)作(zuo)。
拖泵分類(lei)選型
37千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(目前(qian)國(guo)內(nei)標準混凝土泵(beng),37千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)以下(xia)為細石砂(sha)漿泵(beng))、45千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、55千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、75千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、90千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、110千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、130千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴油(you))、132千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴油(you))、174千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴油(you))等。
選擇多(duo)大(da)電(dian)(dian)機混凝(ning)土泵(beng),首先要(yao)考慮變(bian)壓器容量(liang),其次考慮距離混凝(ning)土泵(beng)的遠近和線徑大(da)小,以(yi)免壓降過大(da)造成電(dian)(dian)流(liu)增高(gao)或跳閘停機,過大(da)功(gong)率造成成本增加和使用不(bu)便。電(dian)(dian)機過小,同時也滿足不(bu)了工程需要(yao)。
混(hun)凝(ning)土(tu)輸(shu)送(song)泵功(gong)率、混(hun)凝(ning)土(tu)輸(shu)送(song)泵出口壓(ya)力、混(hun)凝(ning)土(tu)輸(shu)送(song)泵輸(shu)送(song)量之(zhi)間的關(guan)系
一臺混凝土輸(shu)(shu)(shu)送(song)(song)(song)泵的(de)電機功(gong)率是決(jue)定出(chu)口壓力(li)和(he)輸(shu)(shu)(shu)送(song)(song)(song)方量的(de)前提(ti)條件,在電機功(gong)率一定的(de)情況下,壓力(li)的(de)升高必(bi)將(jiang)使輸(shu)(shu)(shu)送(song)(song)(song)量降低;相(xiang)反,降低出(chu)口壓力(li),將(jiang)會使輸(shu)(shu)(shu)送(song)(song)(song)量增加(jia)。
為了保證混凝土(tu)輸(shu)送泵(beng)既(ji)(ji)要有較大(da)(da)輸(shu)送量,又(you)能有一定的(de)出(chu)口(kou)壓力和與之相匹(pi)配的(de)經濟功(gong)率(lv),在混凝土(tu)輸(shu)送泵(beng)的(de)設(she)(she)計中,大(da)(da)都采(cai)用(yong)了恒功(gong)率(lv)柱(zhu)塞泵(beng);即恒功(gong)率(lv)值(zhi)選定后,當出(chu)口(kou)壓力升(sheng)高(gao)時,油(you)泵(beng)輸(shu)出(chu)排量會自(zi)動降低,達到(dao)與功(gong)率(lv)設(she)(she)計相對應的(de)值(zhi);如果既(ji)(ji)要達到(dao)出(chu)口(kou)壓力高(gao),又(you)想得(de)到(dao)輸(shu)送量大(da)(da)的(de)目的(de)。惟一的(de)途徑就是增加電機功(gong)率(lv)。
因此,在(zai)國(guo)家新標準中,引(yin)用了混(hun)凝土輸送(song)(song)泵的(de)(de)(de)(de)能力指(zhi)數概念(以MPa·m3/h為度量(liang)(liang)單位(wei));即混(hun)凝土輸送(song)(song)泵的(de)(de)(de)(de)實際(ji)出口壓(ya)力與(yu)每小時實際(ji)輸送(song)(song)量(liang)(liang)之乘積,該值越(yue)大,其能力指(zhi)數也越(yue)大,電(dian)機的(de)(de)(de)(de)功率也將越(yue)大,由此實現大排量(liang)(liang)、高(gao)揚程的(de)(de)(de)(de)目的(de)(de)(de)(de)。科尼樂公司在(zai)設(she)計時,還(huan)采用了高(gao)低壓(ya)切換的(de)(de)(de)(de)功能設(she)計,以滿足不同的(de)(de)(de)(de)施(shi)工要求,在(zai)經濟(ji)狀態下,又能產(chan)(chan)生較大的(de)(de)(de)(de)輸送(song)(song)量(liang)(liang),或者以相同的(de)(de)(de)(de)電(dian)機功率,產(chan)(chan)生較高(gao)的(de)(de)(de)(de)出口壓(ya)力。
