具體參數
隨(sui)著現代工(gong)業的(de)(de)興(xing)起,以混(hun)凝(ning)土(tu)(tu)為主(zhu)材(cai)料的(de)(de)建設方式已經成(cheng)為了建筑業施工(gong)的(de)(de)主(zhu)要構造之一(yi)(yi),在(zai)各種工(gong)程施工(gong)建設中占據了很大的(de)(de)比例,使得混(hun)凝(ning)土(tu)(tu)機械(xie)的(de)(de)發展經久不衰(shuai),且(qie)有越演越烈的(de)(de)形勢。拖式混(hun)凝(ning)土(tu)(tu)泵,簡(jian)稱拖泵,是(shi)各種混(hun)凝(ning)土(tu)(tu)機械(xie)中的(de)(de)一(yi)(yi)種,用于混(hun)凝(ning)土(tu)(tu)施工(gong)中的(de)(de)輸送和(he)澆注工(gong)作。
拖泵(beng)分類(lei)選型(xing)
37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(目(mu)前國(guo)內標準混凝土泵,37千(qian)(qian)(qian)(qian)瓦(wa)(wa)以下為細石(shi)砂(sha)漿泵)、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))等(deng)。
選(xuan)擇(ze)多(duo)大(da)電機(ji)混凝(ning)土泵,首(shou)先要考(kao)慮(lv)變壓器容量,其次考(kao)慮(lv)距離混凝(ning)土泵的遠(yuan)近和線徑大(da)小,以免壓降過(guo)大(da)造成(cheng)電流增高或跳閘停機(ji),過(guo)大(da)功率造成(cheng)成(cheng)本增加和使用(yong)不便。電機(ji)過(guo)小,同時也滿(man)足不了工程需要。
混凝土(tu)輸(shu)送(song)泵(beng)功率、混凝土(tu)輸(shu)送(song)泵(beng)出口壓力、混凝土(tu)輸(shu)送(song)泵(beng)輸(shu)送(song)量之間(jian)的(de)關系
一臺混凝土輸(shu)(shu)(shu)送(song)(song)泵(beng)的(de)電機功率是決定(ding)出口壓力(li)和輸(shu)(shu)(shu)送(song)(song)方量的(de)前(qian)提(ti)條件(jian),在電機功率一定(ding)的(de)情況下(xia),壓力(li)的(de)升高必(bi)將(jiang)使輸(shu)(shu)(shu)送(song)(song)量降低(di)(di);相反,降低(di)(di)出口壓力(li),將(jiang)會使輸(shu)(shu)(shu)送(song)(song)量增(zeng)加。
為了保證(zheng)混(hun)凝(ning)土輸送(song)泵既要(yao)有(you)較大輸送(song)量(liang),又(you)能有(you)一定(ding)的出口壓(ya)力和與之(zhi)相匹配(pei)的經(jing)濟功(gong)率,在混(hun)凝(ning)土輸送(song)泵的設計中,大都采(cai)用了恒(heng)功(gong)率柱塞泵;即(ji)恒(heng)功(gong)率值選定(ding)后,當出口壓(ya)力升高(gao)時,油泵輸出排量(liang)會自動降低,達(da)到(dao)與功(gong)率設計相對(dui)應的值;如(ru)果既要(yao)達(da)到(dao)出口壓(ya)力高(gao),又(you)想(xiang)得到(dao)輸送(song)量(liang)大的目(mu)的。惟一的途徑就是增(zeng)加電機功(gong)率。
因此,在(zai)國家(jia)新標準中,引用(yong)了混凝土(tu)輸(shu)送(song)泵(beng)的(de)(de)(de)(de)能(neng)力指(zhi)數概(gai)念(以MPa·m3/h為度量單位);即混凝土(tu)輸(shu)送(song)泵(beng)的(de)(de)(de)(de)實際出(chu)口壓(ya)力與每小時實際輸(shu)送(song)量之乘積,該值越大(da)(da),其能(neng)力指(zhi)數也越大(da)(da),電(dian)機(ji)的(de)(de)(de)(de)功(gong)率也將越大(da)(da),由此實現大(da)(da)排量、高(gao)(gao)揚(yang)程的(de)(de)(de)(de)目的(de)(de)(de)(de)。科尼樂公司在(zai)設計(ji)(ji)時,還采用(yong)了高(gao)(gao)低壓(ya)切(qie)換的(de)(de)(de)(de)功(gong)能(neng)設計(ji)(ji),以滿足不同的(de)(de)(de)(de)施工(gong)要求,在(zai)經濟狀態下,又能(neng)產生(sheng)較(jiao)大(da)(da)的(de)(de)(de)(de)輸(shu)送(song)量,或(huo)者以相(xiang)同的(de)(de)(de)(de)電(dian)機(ji)功(gong)率,產生(sheng)較(jiao)高(gao)(gao)的(de)(de)(de)(de)出(chu)口壓(ya)力。
