具體參數
隨(sui)著現代工(gong)(gong)業的(de)(de)興起,以混凝(ning)(ning)土(tu)為主(zhu)材料的(de)(de)建(jian)設方式已經成為了建(jian)筑業施工(gong)(gong)的(de)(de)主(zhu)要(yao)構(gou)造之一,在(zai)各種(zhong)工(gong)(gong)程施工(gong)(gong)建(jian)設中占據了很大的(de)(de)比(bi)例,使得混凝(ning)(ning)土(tu)機械(xie)的(de)(de)發展(zhan)經久不衰,且有越演(yan)越烈的(de)(de)形勢。拖(tuo)式混凝(ning)(ning)土(tu)泵,簡稱拖(tuo)泵,是各種(zhong)混凝(ning)(ning)土(tu)機械(xie)中的(de)(de)一種(zhong),用于混凝(ning)(ning)土(tu)施工(gong)(gong)中的(de)(de)輸送和澆注工(gong)(gong)作。
拖泵分類(lei)選(xuan)型
37千(qian)(qian)(qian)瓦(wa)(目(mu)前國(guo)內標(biao)準混凝土泵(beng),37千(qian)(qian)(qian)瓦(wa)以下為細(xi)石砂漿泵(beng))、45千(qian)(qian)(qian)瓦(wa)、55千(qian)(qian)(qian)瓦(wa)、75千(qian)(qian)(qian)瓦(wa)、90千(qian)(qian)(qian)瓦(wa)、110千(qian)(qian)(qian)瓦(wa)、130千(qian)(qian)(qian)瓦(wa)(柴(chai)油(you))、132千(qian)(qian)(qian)瓦(wa)、162千(qian)(qian)(qian)瓦(wa)(柴(chai)油(you))、174千(qian)(qian)(qian)瓦(wa)(柴(chai)油(you))等。
選(xuan)擇多大(da)(da)電機混凝(ning)土泵,首先要(yao)考慮變壓(ya)器容量,其(qi)次考慮距離(li)混凝(ning)土泵的遠(yuan)近和線(xian)徑大(da)(da)小(xiao)(xiao),以免壓(ya)降過大(da)(da)造成(cheng)電流(liu)增(zeng)(zeng)高或跳閘停機,過大(da)(da)功率造成(cheng)成(cheng)本增(zeng)(zeng)加和使(shi)用不便。電機過小(xiao)(xiao),同時也滿足不了工程需要(yao)。
混凝(ning)(ning)土輸(shu)(shu)送(song)泵(beng)功率、混凝(ning)(ning)土輸(shu)(shu)送(song)泵(beng)出口(kou)壓力、混凝(ning)(ning)土輸(shu)(shu)送(song)泵(beng)輸(shu)(shu)送(song)量之間的關(guan)系
一臺混凝土輸(shu)送(song)(song)泵的電(dian)(dian)機(ji)(ji)功(gong)率(lv)是決定(ding)出口(kou)壓(ya)力和輸(shu)送(song)(song)方量(liang)(liang)的前(qian)提條(tiao)件,在電(dian)(dian)機(ji)(ji)功(gong)率(lv)一定(ding)的情(qing)況(kuang)下(xia),壓(ya)力的升高必將(jiang)使輸(shu)送(song)(song)量(liang)(liang)降低(di);相反,降低(di)出口(kou)壓(ya)力,將(jiang)會使輸(shu)送(song)(song)量(liang)(liang)增(zeng)加。
為了保證(zheng)混凝(ning)土輸(shu)送(song)泵(beng)(beng)既要(yao)有(you)較大輸(shu)送(song)量(liang)(liang),又(you)能(neng)有(you)一(yi)定(ding)的(de)出(chu)(chu)口壓(ya)力(li)和與之相(xiang)匹配的(de)經濟功(gong)(gong)率,在混凝(ning)土輸(shu)送(song)泵(beng)(beng)的(de)設計中,大都采用了恒(heng)功(gong)(gong)率柱塞(sai)泵(beng)(beng);即恒(heng)功(gong)(gong)率值選定(ding)后,當出(chu)(chu)口壓(ya)力(li)升高(gao)時,油泵(beng)(beng)輸(shu)出(chu)(chu)排量(liang)(liang)會自動降低,達到(dao)與功(gong)(gong)率設計相(xiang)對應的(de)值;如果既要(yao)達到(dao)出(chu)(chu)口壓(ya)力(li)高(gao),又(you)想得到(dao)輸(shu)送(song)量(liang)(liang)大的(de)目(mu)的(de)。惟(wei)一(yi)的(de)途徑(jing)就是增加電(dian)機(ji)功(gong)(gong)率。
因此,在國家新標準中,引(yin)用(yong)了混(hun)(hun)凝土輸送(song)泵(beng)的(de)能(neng)(neng)力指數概念(nian)(以MPa·m3/h為度量(liang)單位(wei));即混(hun)(hun)凝土輸送(song)泵(beng)的(de)實際(ji)出口(kou)壓(ya)力與每小時實際(ji)輸送(song)量(liang)之乘積(ji),該(gai)值越大(da),其能(neng)(neng)力指數也越大(da),電(dian)機(ji)的(de)功(gong)率也將(jiang)越大(da),由此實現(xian)大(da)排(pai)量(liang)、高揚程的(de)目的(de)。科尼樂公司在設(she)計時,還采用(yong)了高低壓(ya)切換(huan)的(de)功(gong)能(neng)(neng)設(she)計,以滿足不同的(de)施(shi)工要求,在經濟狀態(tai)下,又能(neng)(neng)產生較大(da)的(de)輸送(song)量(liang),或者以相同的(de)電(dian)機(ji)功(gong)率,產生較高的(de)出口(kou)壓(ya)力。
