具體參數
隨(sui)著現(xian)代工(gong)業的(de)(de)(de)(de)興起,以混(hun)凝(ning)土(tu)為(wei)主材料(liao)的(de)(de)(de)(de)建設方(fang)式已經成為(wei)了建筑業施(shi)工(gong)的(de)(de)(de)(de)主要構造之(zhi)一(yi),在各(ge)種工(gong)程施(shi)工(gong)建設中(zhong)占據了很大的(de)(de)(de)(de)比例(li),使得混(hun)凝(ning)土(tu)機(ji)械的(de)(de)(de)(de)發展經久(jiu)不衰(shuai),且(qie)有越演越烈(lie)的(de)(de)(de)(de)形勢。拖式混(hun)凝(ning)土(tu)泵,簡稱拖泵,是各(ge)種混(hun)凝(ning)土(tu)機(ji)械中(zhong)的(de)(de)(de)(de)一(yi)種,用于混(hun)凝(ning)土(tu)施(shi)工(gong)中(zhong)的(de)(de)(de)(de)輸送和澆注工(gong)作(zuo)。
拖泵分類選(xuan)型(xing)
37千(qian)(qian)(qian)(qian)(qian)瓦(目前國內標準(zhun)混凝土泵(beng),37千(qian)(qian)(qian)(qian)(qian)瓦以下(xia)為細石砂漿(jiang)泵(beng))、45千(qian)(qian)(qian)(qian)(qian)瓦、55千(qian)(qian)(qian)(qian)(qian)瓦、75千(qian)(qian)(qian)(qian)(qian)瓦、90千(qian)(qian)(qian)(qian)(qian)瓦、110千(qian)(qian)(qian)(qian)(qian)瓦、130千(qian)(qian)(qian)(qian)(qian)瓦(柴油)、132千(qian)(qian)(qian)(qian)(qian)瓦、162千(qian)(qian)(qian)(qian)(qian)瓦(柴油)、174千(qian)(qian)(qian)(qian)(qian)瓦(柴油)等(deng)。
選擇多大電(dian)機混凝土泵,首先要(yao)考(kao)慮(lv)變壓(ya)器容量,其次考(kao)慮(lv)距離混凝土泵的(de)遠近(jin)和線徑大小,以免壓(ya)降過(guo)(guo)大造成電(dian)流增高或跳閘停機,過(guo)(guo)大功率造成成本增加和使用不便。電(dian)機過(guo)(guo)小,同時也(ye)滿足不了工程需要(yao)。
混(hun)凝(ning)土輸(shu)(shu)送(song)泵功(gong)率、混(hun)凝(ning)土輸(shu)(shu)送(song)泵出口壓力、混(hun)凝(ning)土輸(shu)(shu)送(song)泵輸(shu)(shu)送(song)量之(zhi)間的(de)關系
一臺混凝土輸(shu)送泵的(de)(de)電(dian)機(ji)功率是(shi)決定出(chu)口壓力(li)(li)和輸(shu)送方量的(de)(de)前提條件,在電(dian)機(ji)功率一定的(de)(de)情況下,壓力(li)(li)的(de)(de)升高(gao)必(bi)將使輸(shu)送量降低;相反,降低出(chu)口壓力(li)(li),將會(hui)使輸(shu)送量增加。
為了保證混(hun)凝土輸送(song)(song)泵既要(yao)有(you)較大輸送(song)(song)量,又能(neng)有(you)一(yi)定(ding)的出口(kou)壓力和(he)與之相匹配(pei)的經(jing)濟功(gong)(gong)率,在混(hun)凝土輸送(song)(song)泵的設計中,大都采用了恒(heng)功(gong)(gong)率柱塞(sai)泵;即(ji)恒(heng)功(gong)(gong)率值選定(ding)后,當出口(kou)壓力升高(gao)時(shi),油泵輸出排(pai)量會自動降低(di),達到與功(gong)(gong)率設計相對應的值;如(ru)果既要(yao)達到出口(kou)壓力高(gao),又想得到輸送(song)(song)量大的目(mu)的。惟一(yi)的途徑就是增加電機(ji)功(gong)(gong)率。
因此(ci),在(zai)國家新標(biao)準(zhun)中(zhong),引用了(le)混(hun)(hun)凝土輸(shu)(shu)送泵的(de)能(neng)力(li)(li)指數概念(以MPa·m3/h為度量(liang)單位);即混(hun)(hun)凝土輸(shu)(shu)送泵的(de)實際出(chu)口壓(ya)力(li)(li)與每小時實際輸(shu)(shu)送量(liang)之乘積(ji),該值越大(da),其能(neng)力(li)(li)指數也(ye)越大(da),電(dian)機的(de)功(gong)(gong)率(lv)也(ye)將越大(da),由此(ci)實現大(da)排量(liang)、高(gao)揚程的(de)目(mu)的(de)。科尼(ni)樂公司(si)在(zai)設計時,還(huan)采用了(le)高(gao)低壓(ya)切換的(de)功(gong)(gong)能(neng)設計,以滿足不同(tong)的(de)施工(gong)要(yao)求,在(zai)經濟狀態(tai)下,又能(neng)產(chan)生(sheng)較(jiao)大(da)的(de)輸(shu)(shu)送量(liang),或(huo)者以相同(tong)的(de)電(dian)機功(gong)(gong)率(lv),產(chan)生(sheng)較(jiao)高(gao)的(de)出(chu)口壓(ya)力(li)(li)。
