具體參數
隨著(zhu)現代工業的興起(qi),以混凝(ning)(ning)土(tu)為(wei)主材料的建(jian)(jian)設(she)方式(shi)已(yi)經成為(wei)了建(jian)(jian)筑業施工的主要構造之一(yi)(yi),在各種(zhong)工程施工建(jian)(jian)設(she)中占據(ju)了很大的比例(li),使得混凝(ning)(ning)土(tu)機(ji)械的發展(zhan)經久不衰(shuai),且有越演越烈的形勢(shi)。拖式(shi)混凝(ning)(ning)土(tu)泵,簡稱拖泵,是各種(zhong)混凝(ning)(ning)土(tu)機(ji)械中的一(yi)(yi)種(zhong),用于(yu)混凝(ning)(ning)土(tu)施工中的輸送和澆(jiao)注(zhu)工作。
拖泵分類(lei)選型
37千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(目(mu)前國內標準混凝土泵,37千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)以下為細石砂漿(jiang)泵)、45千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)油)、132千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)油)、174千(qian)(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)油)等。
選擇多大(da)(da)電(dian)機混凝土泵(beng),首先要考慮(lv)變(bian)壓(ya)器容量,其次考慮(lv)距離混凝土泵(beng)的遠(yuan)近和線徑大(da)(da)小,以免壓(ya)降過(guo)大(da)(da)造成(cheng)電(dian)流增高或(huo)跳閘停機,過(guo)大(da)(da)功率(lv)造成(cheng)成(cheng)本增加和使(shi)用(yong)不(bu)便(bian)。電(dian)機過(guo)小,同時也(ye)滿足(zu)不(bu)了(le)工(gong)程(cheng)需要。
混(hun)凝(ning)土輸(shu)送泵(beng)功率(lv)、混(hun)凝(ning)土輸(shu)送泵(beng)出口壓(ya)力、混(hun)凝(ning)土輸(shu)送泵(beng)輸(shu)送量之間的(de)關系
一(yi)臺(tai)混凝土輸送(song)(song)(song)泵的(de)(de)電機功(gong)率是(shi)決定出口壓力(li)和輸送(song)(song)(song)方量(liang)的(de)(de)前(qian)提條(tiao)件,在電機功(gong)率一(yi)定的(de)(de)情(qing)況下,壓力(li)的(de)(de)升高必將使輸送(song)(song)(song)量(liang)降低(di);相(xiang)反,降低(di)出口壓力(li),將會使輸送(song)(song)(song)量(liang)增加。
為了(le)保(bao)證(zheng)混(hun)凝土(tu)輸(shu)送(song)(song)泵(beng)(beng)既要(yao)有(you)較大輸(shu)送(song)(song)量(liang),又能(neng)有(you)一定(ding)的(de)(de)(de)出(chu)口壓(ya)(ya)力(li)和與之相匹配的(de)(de)(de)經(jing)濟(ji)功(gong)(gong)率(lv)(lv),在混(hun)凝土(tu)輸(shu)送(song)(song)泵(beng)(beng)的(de)(de)(de)設(she)計中,大都采(cai)用了(le)恒功(gong)(gong)率(lv)(lv)柱塞(sai)泵(beng)(beng);即(ji)恒功(gong)(gong)率(lv)(lv)值選定(ding)后,當出(chu)口壓(ya)(ya)力(li)升高(gao)時,油泵(beng)(beng)輸(shu)出(chu)排量(liang)會自動降低,達到與功(gong)(gong)率(lv)(lv)設(she)計相對應的(de)(de)(de)值;如果既要(yao)達到出(chu)口壓(ya)(ya)力(li)高(gao),又想(xiang)得到輸(shu)送(song)(song)量(liang)大的(de)(de)(de)目的(de)(de)(de)。惟一的(de)(de)(de)途徑就是(shi)增加(jia)電(dian)機功(gong)(gong)率(lv)(lv)。
因此,在國家(jia)新標準中(zhong),引用了(le)混凝土(tu)輸(shu)送(song)泵(beng)的(de)能(neng)力(li)指數概(gai)念(nian)(以(yi)(yi)MPa·m3/h為度量(liang)單位);即(ji)混凝土(tu)輸(shu)送(song)泵(beng)的(de)實(shi)際(ji)出口壓力(li)與每小時實(shi)際(ji)輸(shu)送(song)量(liang)之乘(cheng)積,該值越(yue)大(da),其(qi)能(neng)力(li)指數也越(yue)大(da),電機的(de)功(gong)率也將(jiang)越(yue)大(da),由此實(shi)現大(da)排量(liang)、高揚程(cheng)的(de)目的(de)。科尼(ni)樂公司(si)在設(she)計時,還采用了(le)高低(di)壓切換的(de)功(gong)能(neng)設(she)計,以(yi)(yi)滿足不同的(de)施(shi)工要求(qiu),在經濟狀(zhuang)態下,又能(neng)產生較大(da)的(de)輸(shu)送(song)量(liang),或者以(yi)(yi)相同的(de)電機功(gong)率,產生較高的(de)出口壓力(li)。
