具體參數
隨著現代工業的(de)(de)興起,以混(hun)凝(ning)(ning)土(tu)為主(zhu)材(cai)料的(de)(de)建(jian)(jian)(jian)設(she)方式已經(jing)(jing)成為了建(jian)(jian)(jian)筑業施(shi)工的(de)(de)主(zhu)要(yao)構造之(zhi)一(yi),在各(ge)種(zhong)工程施(shi)工建(jian)(jian)(jian)設(she)中占據(ju)了很大的(de)(de)比例,使得混(hun)凝(ning)(ning)土(tu)機(ji)械的(de)(de)發展經(jing)(jing)久不衰,且(qie)有越(yue)(yue)演越(yue)(yue)烈的(de)(de)形勢。拖式混(hun)凝(ning)(ning)土(tu)泵(beng),簡稱拖泵(beng),是各(ge)種(zhong)混(hun)凝(ning)(ning)土(tu)機(ji)械中的(de)(de)一(yi)種(zhong),用于混(hun)凝(ning)(ning)土(tu)施(shi)工中的(de)(de)輸送(song)和(he)澆注工作(zuo)。
拖泵分類(lei)選型
37千(qian)(qian)(qian)瓦(wa)(wa)(wa)(目(mu)前國內標準混凝(ning)土泵,37千(qian)(qian)(qian)瓦(wa)(wa)(wa)以(yi)下為(wei)細石砂漿泵)、45千(qian)(qian)(qian)瓦(wa)(wa)(wa)、55千(qian)(qian)(qian)瓦(wa)(wa)(wa)、75千(qian)(qian)(qian)瓦(wa)(wa)(wa)、90千(qian)(qian)(qian)瓦(wa)(wa)(wa)、110千(qian)(qian)(qian)瓦(wa)(wa)(wa)、130千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油)、132千(qian)(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油)、174千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油)等(deng)。
選擇多大電機(ji)(ji)混凝土(tu)泵,首先要(yao)考慮變壓(ya)器(qi)容量(liang),其次(ci)考慮距(ju)離混凝土(tu)泵的遠近和線(xian)徑大小(xiao),以(yi)免壓(ya)降過(guo)大造成(cheng)電流增高或(huo)跳閘停機(ji)(ji),過(guo)大功率造成(cheng)成(cheng)本增加和使用不便。電機(ji)(ji)過(guo)小(xiao),同時也滿足(zu)不了(le)工程需(xu)要(yao)。
混(hun)凝(ning)土輸(shu)送泵(beng)(beng)功率、混(hun)凝(ning)土輸(shu)送泵(beng)(beng)出口壓力、混(hun)凝(ning)土輸(shu)送泵(beng)(beng)輸(shu)送量之間的(de)關系(xi)
一(yi)臺混(hun)凝土輸(shu)送(song)(song)泵的電(dian)機功率是(shi)決定出(chu)口壓力和輸(shu)送(song)(song)方量(liang)的前提條件,在電(dian)機功率一(yi)定的情況(kuang)下,壓力的升高必將使輸(shu)送(song)(song)量(liang)降低(di);相反,降低(di)出(chu)口壓力,將會使輸(shu)送(song)(song)量(liang)增加(jia)。
為了(le)保證混凝(ning)土(tu)(tu)輸(shu)(shu)送(song)泵(beng)既要有較大輸(shu)(shu)送(song)量,又(you)能有一(yi)定的(de)(de)出(chu)(chu)口(kou)壓(ya)(ya)力(li)和與之相匹配的(de)(de)經(jing)濟功(gong)(gong)(gong)率,在混凝(ning)土(tu)(tu)輸(shu)(shu)送(song)泵(beng)的(de)(de)設計中,大都采用了(le)恒功(gong)(gong)(gong)率柱塞泵(beng);即(ji)恒功(gong)(gong)(gong)率值選(xuan)定后,當出(chu)(chu)口(kou)壓(ya)(ya)力(li)升(sheng)高時,油泵(beng)輸(shu)(shu)出(chu)(chu)排量會自動降低(di),達(da)到與功(gong)(gong)(gong)率設計相對(dui)應的(de)(de)值;如果既要達(da)到出(chu)(chu)口(kou)壓(ya)(ya)力(li)高,又(you)想得到輸(shu)(shu)送(song)量大的(de)(de)目的(de)(de)。惟(wei)一(yi)的(de)(de)途徑就是增(zeng)加電(dian)機功(gong)(gong)(gong)率。
因(yin)此,在(zai)(zai)國家(jia)新標準(zhun)中,引用了混凝土輸(shu)(shu)(shu)送(song)泵的能(neng)(neng)力(li)(li)指數概念(以MPa·m3/h為(wei)度量(liang)(liang)單位);即(ji)混凝土輸(shu)(shu)(shu)送(song)泵的實(shi)際(ji)出口(kou)壓(ya)力(li)(li)與每小時實(shi)際(ji)輸(shu)(shu)(shu)送(song)量(liang)(liang)之乘積(ji),該值越(yue)(yue)大(da),其能(neng)(neng)力(li)(li)指數也(ye)越(yue)(yue)大(da),電機(ji)的功率(lv)也(ye)將越(yue)(yue)大(da),由此實(shi)現大(da)排(pai)量(liang)(liang)、高揚程(cheng)的目的。科尼樂公(gong)司(si)在(zai)(zai)設計(ji)時,還采用了高低壓(ya)切換的功能(neng)(neng)設計(ji),以滿足不(bu)同的施(shi)工要求,在(zai)(zai)經濟狀態(tai)下,又能(neng)(neng)產生較大(da)的輸(shu)(shu)(shu)送(song)量(liang)(liang),或者以相同的電機(ji)功率(lv),產生較高的出口(kou)壓(ya)力(li)(li)。
