具體參數
隨著現代(dai)工(gong)(gong)(gong)業的(de)(de)(de)興(xing)起,以混(hun)凝土為主(zhu)材(cai)料的(de)(de)(de)建(jian)(jian)(jian)設(she)方式(shi)已經成(cheng)為了建(jian)(jian)(jian)筑(zhu)業施(shi)工(gong)(gong)(gong)的(de)(de)(de)主(zhu)要構造(zao)之(zhi)一,在(zai)各(ge)種工(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)建(jian)(jian)(jian)設(she)中(zhong)占據了很大(da)的(de)(de)(de)比例(li),使得(de)混(hun)凝土機(ji)械(xie)的(de)(de)(de)發展經久不(bu)衰,且有越(yue)演(yan)越(yue)烈的(de)(de)(de)形勢(shi)。拖(tuo)式(shi)混(hun)凝土泵,簡稱拖(tuo)泵,是各(ge)種混(hun)凝土機(ji)械(xie)中(zhong)的(de)(de)(de)一種,用于(yu)混(hun)凝土施(shi)工(gong)(gong)(gong)中(zhong)的(de)(de)(de)輸送和澆注工(gong)(gong)(gong)作。
拖(tuo)泵分類選型(xing)
37千(qian)(qian)(qian)瓦(wa)(wa)(wa)(目前國內標準混凝(ning)土泵,37千(qian)(qian)(qian)瓦(wa)(wa)(wa)以下(xia)為細石砂漿泵)、45千(qian)(qian)(qian)瓦(wa)(wa)(wa)、55千(qian)(qian)(qian)瓦(wa)(wa)(wa)、75千(qian)(qian)(qian)瓦(wa)(wa)(wa)、90千(qian)(qian)(qian)瓦(wa)(wa)(wa)、110千(qian)(qian)(qian)瓦(wa)(wa)(wa)、130千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油)、132千(qian)(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油)、174千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油)等。
選(xuan)擇多大(da)(da)電(dian)(dian)機混凝土(tu)泵,首先要考(kao)慮變壓(ya)器容量(liang),其次考(kao)慮距離(li)混凝土(tu)泵的(de)遠(yuan)近(jin)和線徑大(da)(da)小(xiao),以免壓(ya)降過大(da)(da)造(zao)成(cheng)(cheng)電(dian)(dian)流增高或(huo)跳閘停機,過大(da)(da)功(gong)率(lv)造(zao)成(cheng)(cheng)成(cheng)(cheng)本增加和使用(yong)不便。電(dian)(dian)機過小(xiao),同時也滿足不了(le)工程需要。
混(hun)凝(ning)土輸(shu)送(song)泵(beng)功率、混(hun)凝(ning)土輸(shu)送(song)泵(beng)出口壓力、混(hun)凝(ning)土輸(shu)送(song)泵(beng)輸(shu)送(song)量之間的關系
一臺混(hun)凝土輸送(song)泵的(de)電機(ji)功(gong)率是決定(ding)出口壓(ya)力和輸送(song)方量(liang)的(de)前提條(tiao)件,在電機(ji)功(gong)率一定(ding)的(de)情況(kuang)下,壓(ya)力的(de)升高必將(jiang)使輸送(song)量(liang)降低(di);相反,降低(di)出口壓(ya)力,將(jiang)會使輸送(song)量(liang)增加。
為了保證混凝(ning)土輸送泵既要有較大(da)(da)輸送量(liang),又(you)能有一(yi)定的(de)(de)(de)出(chu)口(kou)壓(ya)(ya)力(li)(li)和(he)與之(zhi)相匹配的(de)(de)(de)經濟功率,在(zai)混凝(ning)土輸送泵的(de)(de)(de)設(she)計中(zhong),大(da)(da)都采用(yong)了恒功率柱塞(sai)泵;即恒功率值選(xuan)定后,當出(chu)口(kou)壓(ya)(ya)力(li)(li)升高時(shi),油泵輸出(chu)排(pai)量(liang)會自動降低(di),達到(dao)與功率設(she)計相對應的(de)(de)(de)值;如(ru)果(guo)既要達到(dao)出(chu)口(kou)壓(ya)(ya)力(li)(li)高,又(you)想得到(dao)輸送量(liang)大(da)(da)的(de)(de)(de)目的(de)(de)(de)。惟(wei)一(yi)的(de)(de)(de)途徑就是增加電機(ji)功率。
因此(ci),在(zai)國家新(xin)標準(zhun)中,引用了混凝土輸送(song)泵(beng)的(de)(de)能(neng)力指數(shu)概念(以MPa·m3/h為度量單(dan)位(wei));即混凝土輸送(song)泵(beng)的(de)(de)實際出口(kou)壓力與每小(xiao)時(shi)實際輸送(song)量之乘積,該值越大(da),其能(neng)力指數(shu)也(ye)越大(da),電(dian)機的(de)(de)功(gong)率(lv)也(ye)將越大(da),由此(ci)實現大(da)排量、高(gao)揚程的(de)(de)目的(de)(de)。科尼樂公司(si)在(zai)設(she)計(ji)時(shi),還采用了高(gao)低壓切(qie)換的(de)(de)功(gong)能(neng)設(she)計(ji),以滿(man)足(zu)不同的(de)(de)施工要求,在(zai)經濟狀態下,又能(neng)產生較大(da)的(de)(de)輸送(song)量,或者(zhe)以相同的(de)(de)電(dian)機功(gong)率(lv),產生較高(gao)的(de)(de)出口(kou)壓力。
