具體參數
隨著現代(dai)工(gong)(gong)(gong)業的(de)(de)興(xing)起(qi),以(yi)混(hun)凝(ning)土(tu)為主材料(liao)的(de)(de)建設(she)方式已經成為了建筑業施工(gong)(gong)(gong)的(de)(de)主要構造之一(yi),在各(ge)(ge)種(zhong)工(gong)(gong)(gong)程施工(gong)(gong)(gong)建設(she)中(zhong)占據了很大(da)的(de)(de)比例,使得混(hun)凝(ning)土(tu)機械(xie)(xie)的(de)(de)發展經久(jiu)不衰,且有越演(yan)越烈的(de)(de)形勢。拖式混(hun)凝(ning)土(tu)泵,簡(jian)稱拖泵,是各(ge)(ge)種(zhong)混(hun)凝(ning)土(tu)機械(xie)(xie)中(zhong)的(de)(de)一(yi)種(zhong),用于混(hun)凝(ning)土(tu)施工(gong)(gong)(gong)中(zhong)的(de)(de)輸送和澆注工(gong)(gong)(gong)作。
拖(tuo)泵分類選型
37千(qian)(qian)瓦(wa)(wa)(wa)(wa)(wa)(目(mu)前國內(nei)標準混凝土泵(beng)(beng),37千(qian)(qian)瓦(wa)(wa)(wa)(wa)(wa)以下為細石砂漿(jiang)泵(beng)(beng))、45千(qian)(qian)瓦(wa)(wa)(wa)(wa)(wa)、55千(qian)(qian)瓦(wa)(wa)(wa)(wa)(wa)、75千(qian)(qian)瓦(wa)(wa)(wa)(wa)(wa)、90千(qian)(qian)瓦(wa)(wa)(wa)(wa)(wa)、110千(qian)(qian)瓦(wa)(wa)(wa)(wa)(wa)、130千(qian)(qian)瓦(wa)(wa)(wa)(wa)(wa)(柴(chai)油(you)(you))、132千(qian)(qian)瓦(wa)(wa)(wa)(wa)(wa)、162千(qian)(qian)瓦(wa)(wa)(wa)(wa)(wa)(柴(chai)油(you)(you))、174千(qian)(qian)瓦(wa)(wa)(wa)(wa)(wa)(柴(chai)油(you)(you))等。
選擇多大(da)電機(ji)混(hun)凝土(tu)泵(beng),首(shou)先要考慮(lv)變(bian)壓器容量,其次考慮(lv)距離混(hun)凝土(tu)泵(beng)的遠近和(he)線徑(jing)大(da)小(xiao),以免(mian)壓降過大(da)造成(cheng)電流(liu)增(zeng)高(gao)或(huo)跳閘(zha)停(ting)機(ji),過大(da)功率造成(cheng)成(cheng)本(ben)增(zeng)加和(he)使用不(bu)便。電機(ji)過小(xiao),同時(shi)也滿足不(bu)了工程需要。
混(hun)凝(ning)(ning)土(tu)(tu)(tu)輸(shu)(shu)送(song)泵功率、混(hun)凝(ning)(ning)土(tu)(tu)(tu)輸(shu)(shu)送(song)泵出口壓力、混(hun)凝(ning)(ning)土(tu)(tu)(tu)輸(shu)(shu)送(song)泵輸(shu)(shu)送(song)量之間的關系
一臺混凝土(tu)輸送泵的電機功(gong)率是決定出(chu)口(kou)壓力和(he)輸送方量的前(qian)提條件,在電機功(gong)率一定的情況下,壓力的升高必(bi)將(jiang)使(shi)輸送量降(jiang)低(di);相(xiang)反,降(jiang)低(di)出(chu)口(kou)壓力,將(jiang)會使(shi)輸送量增加(jia)。
為了(le)保證混凝土輸(shu)送(song)泵(beng)既(ji)要有(you)較大(da)輸(shu)送(song)量(liang),又(you)能有(you)一定的出(chu)(chu)口(kou)壓(ya)力和與(yu)之相(xiang)匹配的經濟功(gong)率(lv)(lv)(lv),在混凝土輸(shu)送(song)泵(beng)的設(she)計中,大(da)都采用了(le)恒功(gong)率(lv)(lv)(lv)柱塞(sai)泵(beng);即(ji)恒功(gong)率(lv)(lv)(lv)值(zhi)選定后,當出(chu)(chu)口(kou)壓(ya)力升高時(shi),油泵(beng)輸(shu)出(chu)(chu)排量(liang)會自動降(jiang)低,達(da)到與(yu)功(gong)率(lv)(lv)(lv)設(she)計相(xiang)對應的值(zhi);如果既(ji)要達(da)到出(chu)(chu)口(kou)壓(ya)力高,又(you)想得到輸(shu)送(song)量(liang)大(da)的目的。惟一的途徑就是(shi)增(zeng)加(jia)電機功(gong)率(lv)(lv)(lv)。
因此(ci),在國家新標(biao)準(zhun)中,引用了(le)混凝土輸(shu)(shu)送(song)(song)泵(beng)(beng)的(de)(de)能(neng)力指(zhi)數概念(nian)(以(yi)MPa·m3/h為(wei)度量單位);即(ji)混凝土輸(shu)(shu)送(song)(song)泵(beng)(beng)的(de)(de)實(shi)際(ji)出口壓力與(yu)每小時(shi)實(shi)際(ji)輸(shu)(shu)送(song)(song)量之乘積(ji),該值越大(da),其能(neng)力指(zhi)數也越大(da),電(dian)機的(de)(de)功率(lv)(lv)也將越大(da),由此(ci)實(shi)現大(da)排(pai)量、高揚程(cheng)的(de)(de)目(mu)的(de)(de)。科尼樂公(gong)司在設(she)(she)計(ji)時(shi),還采用了(le)高低(di)壓切(qie)換的(de)(de)功能(neng)設(she)(she)計(ji),以(yi)滿足不同的(de)(de)施工要求,在經(jing)濟狀態下,又能(neng)產(chan)生(sheng)較(jiao)大(da)的(de)(de)輸(shu)(shu)送(song)(song)量,或者以(yi)相(xiang)同的(de)(de)電(dian)機功率(lv)(lv),產(chan)生(sheng)較(jiao)高的(de)(de)出口壓力。
