隨著現代(dai)工業的(de)(de)興(xing)起(qi),以(yi)混(hun)(hun)凝(ning)(ning)土(tu)為主(zhu)材料的(de)(de)建設方(fang)式(shi)已經成為了建筑業施(shi)工的(de)(de)主(zhu)要構(gou)造(zao)之一,在各(ge)種(zhong)工程施(shi)工建設中(zhong)占據了很大的(de)(de)比例,使得混(hun)(hun)凝(ning)(ning)土(tu)機械的(de)(de)發展經久不衰,且(qie)有越演越烈的(de)(de)形勢。拖式(shi)混(hun)(hun)凝(ning)(ning)土(tu)泵(beng),簡稱拖泵(beng),是各(ge)種(zhong)混(hun)(hun)凝(ning)(ning)土(tu)機械中(zhong)的(de)(de)一種(zhong),用于(yu)混(hun)(hun)凝(ning)(ning)土(tu)施(shi)工中(zhong)的(de)(de)輸送和澆注工作。
拖泵分類選型
37千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(目(mu)前國內標準混(hun)凝土泵(beng),37千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)以下(xia)為細石砂漿泵(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(chai)油)、132千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)油)、174千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)油)等(deng)。
選擇多大電(dian)(dian)機混凝土泵(beng),首先要考(kao)慮變壓(ya)器容(rong)量,其次考(kao)慮距離(li)混凝土泵(beng)的遠(yuan)近和(he)線徑大小,以免壓(ya)降(jiang)過大造(zao)(zao)成電(dian)(dian)流增(zeng)高(gao)或(huo)跳閘停機,過大功率造(zao)(zao)成成本增(zeng)加(jia)和(he)使用不(bu)便。電(dian)(dian)機過小,同時也滿足不(bu)了工程需要。
混(hun)凝(ning)(ning)土(tu)輸(shu)送(song)泵(beng)功率(lv)、混(hun)凝(ning)(ning)土(tu)輸(shu)送(song)泵(beng)出口壓(ya)力、混(hun)凝(ning)(ning)土(tu)輸(shu)送(song)泵(beng)輸(shu)送(song)量(liang)之間的(de)關系(xi)
一臺混凝土輸(shu)送(song)(song)泵的電機功(gong)率是決定出口壓力(li)和輸(shu)送(song)(song)方量(liang)的前提條件,在(zai)電機功(gong)率一定的情況下,壓力(li)的升高必將(jiang)使輸(shu)送(song)(song)量(liang)降低(di);相反(fan),降低(di)出口壓力(li),將(jiang)會使輸(shu)送(song)(song)量(liang)增(zeng)加。
為了保證混(hun)凝土(tu)輸送(song)泵(beng)既要有較大(da)輸送(song)量(liang),又(you)(you)能有一定的(de)(de)出(chu)(chu)口壓(ya)力(li)和與之相(xiang)匹配的(de)(de)經濟(ji)功(gong)(gong)率(lv),在(zai)混(hun)凝土(tu)輸送(song)泵(beng)的(de)(de)設計中,大(da)都采(cai)用了恒功(gong)(gong)率(lv)柱(zhu)塞泵(beng);即恒功(gong)(gong)率(lv)值選定后(hou),當出(chu)(chu)口壓(ya)力(li)升高(gao)時,油泵(beng)輸出(chu)(chu)排量(liang)會(hui)自動降低,達到與功(gong)(gong)率(lv)設計相(xiang)對應的(de)(de)值;如(ru)果既要達到出(chu)(chu)口壓(ya)力(li)高(gao),又(you)(you)想得(de)到輸送(song)量(liang)大(da)的(de)(de)目的(de)(de)。惟一的(de)(de)途(tu)徑(jing)就是(shi)增加電機功(gong)(gong)率(lv)。
因(yin)此,在國家新(xin)標準中,引(yin)用(yong)了混凝土(tu)輸(shu)(shu)送(song)(song)(song)泵的(de)(de)(de)能力指數概(gai)念(以(yi)MPa·m3/h為(wei)度量(liang)單位);即混凝土(tu)輸(shu)(shu)送(song)(song)(song)泵的(de)(de)(de)實(shi)際出(chu)口(kou)壓(ya)力與每小時(shi)實(shi)際輸(shu)(shu)送(song)(song)(song)量(liang)之乘(cheng)積,該值越大(da),其能力指數也越大(da),電(dian)機的(de)(de)(de)功(gong)率(lv)(lv)也將越大(da),由此實(shi)現(xian)大(da)排量(liang)、高(gao)揚程的(de)(de)(de)目的(de)(de)(de)。科(ke)尼樂公司在設計時(shi),還采用(yong)了高(gao)低(di)壓(ya)切(qie)換的(de)(de)(de)功(gong)能設計,以(yi)滿足不同的(de)(de)(de)施(shi)工要求,在經濟狀態下,又能產生較(jiao)大(da)的(de)(de)(de)輸(shu)(shu)送(song)(song)(song)量(liang),或者以(yi)相同的(de)(de)(de)電(dian)機功(gong)率(lv)(lv),產生較(jiao)高(gao)的(de)(de)(de)出(chu)口(kou)壓(ya)力。
