具體參數
隨著(zhu)現代工(gong)業的(de)興起,以混(hun)(hun)(hun)凝(ning)(ning)土(tu)為主材料的(de)建(jian)(jian)設(she)方式已經(jing)成(cheng)為了建(jian)(jian)筑業施(shi)工(gong)的(de)主要構造之(zhi)一(yi),在各(ge)(ge)種工(gong)程施(shi)工(gong)建(jian)(jian)設(she)中(zhong)占據(ju)了很大的(de)比例,使得(de)混(hun)(hun)(hun)凝(ning)(ning)土(tu)機械的(de)發展經(jing)久(jiu)不衰,且有越演越烈的(de)形勢。拖(tuo)式混(hun)(hun)(hun)凝(ning)(ning)土(tu)泵,簡稱(cheng)拖(tuo)泵,是各(ge)(ge)種混(hun)(hun)(hun)凝(ning)(ning)土(tu)機械中(zhong)的(de)一(yi)種,用(yong)于混(hun)(hun)(hun)凝(ning)(ning)土(tu)施(shi)工(gong)中(zhong)的(de)輸送和澆注工(gong)作。
拖泵分類選型
37千(qian)(qian)瓦(wa)(目前國內(nei)標準(zhun)混凝土(tu)泵(beng),37千(qian)(qian)瓦(wa)以下為細石砂漿(jiang)泵(beng))、45千(qian)(qian)瓦(wa)、55千(qian)(qian)瓦(wa)、75千(qian)(qian)瓦(wa)、90千(qian)(qian)瓦(wa)、110千(qian)(qian)瓦(wa)、130千(qian)(qian)瓦(wa)(柴油(you))、132千(qian)(qian)瓦(wa)、162千(qian)(qian)瓦(wa)(柴油(you))、174千(qian)(qian)瓦(wa)(柴油(you))等。
選(xuan)擇多大電(dian)(dian)機混凝(ning)土泵,首先(xian)要考慮變壓器容量,其次考慮距離混凝(ning)土泵的(de)遠(yuan)近和(he)線徑大小(xiao),以免壓降過(guo)大造(zao)成電(dian)(dian)流增高或跳閘停機,過(guo)大功(gong)率造(zao)成成本增加和(he)使用不(bu)便(bian)。電(dian)(dian)機過(guo)小(xiao),同(tong)時也滿足(zu)不(bu)了工程需要。
混凝土(tu)(tu)輸送(song)(song)泵(beng)功率、混凝土(tu)(tu)輸送(song)(song)泵(beng)出口壓(ya)力、混凝土(tu)(tu)輸送(song)(song)泵(beng)輸送(song)(song)量之間(jian)的(de)關系
一臺混凝土輸(shu)(shu)送泵的電機(ji)功(gong)率(lv)是決定出(chu)口壓(ya)(ya)力(li)(li)和輸(shu)(shu)送方量的前(qian)提條件,在電機(ji)功(gong)率(lv)一定的情(qing)況下,壓(ya)(ya)力(li)(li)的升高必將使輸(shu)(shu)送量降(jiang)低(di);相(xiang)反,降(jiang)低(di)出(chu)口壓(ya)(ya)力(li)(li),將會使輸(shu)(shu)送量增加。
為了保證(zheng)混凝(ning)土(tu)輸(shu)(shu)送(song)(song)(song)泵(beng)既(ji)要有較(jiao)大(da)輸(shu)(shu)送(song)(song)(song)量,又能(neng)有一定的(de)出口(kou)(kou)壓力和與之相(xiang)匹配的(de)經濟功(gong)率(lv),在混凝(ning)土(tu)輸(shu)(shu)送(song)(song)(song)泵(beng)的(de)設(she)計中,大(da)都采用了恒(heng)功(gong)率(lv)柱塞(sai)泵(beng);即恒(heng)功(gong)率(lv)值選定后,當出口(kou)(kou)壓力升高(gao)時,油泵(beng)輸(shu)(shu)出排量會自動降低(di),達到與功(gong)率(lv)設(she)計相(xiang)對應的(de)值;如果既(ji)要達到出口(kou)(kou)壓力高(gao),又想得到輸(shu)(shu)送(song)(song)(song)量大(da)的(de)目的(de)。惟一的(de)途徑就是(shi)增加電(dian)機功(gong)率(lv)。
因(yin)此,在(zai)國家新標準中(zhong),引用(yong)了混凝(ning)土輸送泵(beng)的能(neng)力(li)指(zhi)數概念(以(yi)(yi)MPa·m3/h為度量(liang)(liang)單位);即混凝(ning)土輸送泵(beng)的實(shi)(shi)際出口壓(ya)力(li)與每小時實(shi)(shi)際輸送量(liang)(liang)之乘積(ji),該(gai)值越大(da)(da),其能(neng)力(li)指(zhi)數也(ye)越大(da)(da),電機的功(gong)率(lv)也(ye)將(jiang)越大(da)(da),由此實(shi)(shi)現大(da)(da)排量(liang)(liang)、高揚程的目的。科尼樂公(gong)司在(zai)設(she)計時,還采用(yong)了高低壓(ya)切(qie)換的功(gong)能(neng)設(she)計,以(yi)(yi)滿(man)足不同的施工要求,在(zai)經濟(ji)狀(zhuang)態下,又(you)能(neng)產生(sheng)較大(da)(da)的輸送量(liang)(liang),或(huo)者以(yi)(yi)相同的電機功(gong)率(lv),產生(sheng)較高的出口壓(ya)力(li)。
