具體參數
隨著現代工(gong)(gong)(gong)業的(de)(de)興(xing)起,以混(hun)凝(ning)(ning)土(tu)為主材(cai)料的(de)(de)建(jian)設方式(shi)已經成為了(le)(le)建(jian)筑業施工(gong)(gong)(gong)的(de)(de)主要(yao)構造(zao)之一(yi),在各種工(gong)(gong)(gong)程施工(gong)(gong)(gong)建(jian)設中占(zhan)據(ju)了(le)(le)很大(da)的(de)(de)比例(li),使得混(hun)凝(ning)(ning)土(tu)機(ji)械(xie)的(de)(de)發展經久不衰(shuai),且有越演越烈的(de)(de)形勢。拖式(shi)混(hun)凝(ning)(ning)土(tu)泵,簡稱拖泵,是各種混(hun)凝(ning)(ning)土(tu)機(ji)械(xie)中的(de)(de)一(yi)種,用于混(hun)凝(ning)(ning)土(tu)施工(gong)(gong)(gong)中的(de)(de)輸送和澆注工(gong)(gong)(gong)作。
拖泵(beng)分類選(xuan)型
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)以下為細(xi)石砂(sha)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)(柴油)、132千(qian)(qian)(qian)(qian)瓦(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(柴油)、174千(qian)(qian)(qian)(qian)瓦(wa)(柴油)等(deng)。
選擇多大(da)電機混凝土泵,首先要考(kao)慮(lv)變壓(ya)(ya)器容量,其次考(kao)慮(lv)距離混凝土泵的遠近和線徑大(da)小,以免(mian)壓(ya)(ya)降過(guo)(guo)大(da)造成電流(liu)增高或跳閘停(ting)機,過(guo)(guo)大(da)功率造成成本增加和使用不便。電機過(guo)(guo)小,同時也滿(man)足不了工程需要。
混(hun)凝土輸(shu)送(song)泵功率、混(hun)凝土輸(shu)送(song)泵出(chu)口壓(ya)力、混(hun)凝土輸(shu)送(song)泵輸(shu)送(song)量(liang)之間的關系
一臺混凝土輸(shu)送泵的電(dian)機功(gong)率是決(jue)定出(chu)口壓力(li)(li)(li)和輸(shu)送方(fang)量(liang)的前提條(tiao)件(jian),在電(dian)機功(gong)率一定的情況下,壓力(li)(li)(li)的升高(gao)必將(jiang)使輸(shu)送量(liang)降低;相反,降低出(chu)口壓力(li)(li)(li),將(jiang)會使輸(shu)送量(liang)增加。
為了(le)保證混凝(ning)土輸(shu)(shu)送(song)泵(beng)(beng)既(ji)要有較大(da)輸(shu)(shu)送(song)量,又能有一定(ding)的出(chu)口壓力和與之相匹配的經濟功率(lv)(lv),在混凝(ning)土輸(shu)(shu)送(song)泵(beng)(beng)的設計(ji)中(zhong),大(da)都采用了(le)恒功率(lv)(lv)柱塞泵(beng)(beng);即(ji)恒功率(lv)(lv)值(zhi)選定(ding)后,當出(chu)口壓力升高時,油泵(beng)(beng)輸(shu)(shu)出(chu)排量會自(zi)動降低,達到與功率(lv)(lv)設計(ji)相對(dui)應的值(zhi);如(ru)果既(ji)要達到出(chu)口壓力高,又想得到輸(shu)(shu)送(song)量大(da)的目的。惟一的途(tu)徑就(jiu)是增加電機功率(lv)(lv)。
因此,在(zai)國家新標準中,引(yin)用了混凝土輸(shu)(shu)(shu)送(song)泵的(de)(de)能(neng)力指(zhi)(zhi)數概(gai)念(以(yi)(yi)MPa·m3/h為度量(liang)單位(wei));即混凝土輸(shu)(shu)(shu)送(song)泵的(de)(de)實(shi)際出口壓力與(yu)每小時(shi)(shi)實(shi)際輸(shu)(shu)(shu)送(song)量(liang)之乘(cheng)積,該(gai)值越(yue)(yue)大,其能(neng)力指(zhi)(zhi)數也越(yue)(yue)大,電(dian)機(ji)的(de)(de)功率也將越(yue)(yue)大,由(you)此實(shi)現(xian)大排量(liang)、高揚程的(de)(de)目的(de)(de)。科(ke)尼(ni)樂公司(si)在(zai)設(she)計時(shi)(shi),還采用了高低壓切換的(de)(de)功能(neng)設(she)計,以(yi)(yi)滿足(zu)不同的(de)(de)施工要(yao)求,在(zai)經濟狀態下(xia),又能(neng)產(chan)生(sheng)較(jiao)大的(de)(de)輸(shu)(shu)(shu)送(song)量(liang),或者(zhe)以(yi)(yi)相同的(de)(de)電(dian)機(ji)功率,產(chan)生(sheng)較(jiao)高的(de)(de)出口壓力。
