具(ju)體參數
隨著現代工(gong)(gong)業的(de)(de)(de)興起(qi),以混凝(ning)土(tu)(tu)(tu)為主(zhu)(zhu)材料(liao)的(de)(de)(de)建(jian)設(she)方(fang)式(shi)已經成為了建(jian)筑業施工(gong)(gong)的(de)(de)(de)主(zhu)(zhu)要(yao)構造之一,在各種工(gong)(gong)程施工(gong)(gong)建(jian)設(she)中(zhong)占據了很大的(de)(de)(de)比(bi)例,使得混凝(ning)土(tu)(tu)(tu)機械的(de)(de)(de)發展經久不衰,且有(you)越演(yan)越烈的(de)(de)(de)形勢(shi)。拖(tuo)式(shi)混凝(ning)土(tu)(tu)(tu)泵,簡稱(cheng)拖(tuo)泵,是(shi)各種混凝(ning)土(tu)(tu)(tu)機械中(zhong)的(de)(de)(de)一種,用(yong)于混凝(ning)土(tu)(tu)(tu)施工(gong)(gong)中(zhong)的(de)(de)(de)輸送和(he)澆(jiao)注工(gong)(gong)作(zuo)。
拖泵分類(lei)選型
37千(qian)(qian)(qian)(qian)瓦(wa)(目(mu)前(qian)國內標準混凝土(tu)泵,37千(qian)(qian)(qian)(qian)瓦(wa)以下為細(xi)石砂(sha)漿泵)、45千(qian)(qian)(qian)(qian)瓦(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(柴(chai)油(you))、132千(qian)(qian)(qian)(qian)瓦(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(柴(chai)油(you))、174千(qian)(qian)(qian)(qian)瓦(wa)(柴(chai)油(you))等。
選擇多大(da)電機混(hun)(hun)凝土(tu)泵,首先(xian)要(yao)考(kao)慮變壓器容(rong)量,其次考(kao)慮距離混(hun)(hun)凝土(tu)泵的遠(yuan)近(jin)和線徑大(da)小,以免(mian)壓降過(guo)大(da)造成(cheng)電流增(zeng)(zeng)高或(huo)跳閘(zha)停機,過(guo)大(da)功率(lv)造成(cheng)成(cheng)本增(zeng)(zeng)加和使用不便。電機過(guo)小,同時(shi)也(ye)滿足不了(le)工(gong)程需要(yao)。
混(hun)凝土(tu)(tu)輸送泵(beng)功率(lv)、混(hun)凝土(tu)(tu)輸送泵(beng)出(chu)口壓力、混(hun)凝土(tu)(tu)輸送泵(beng)輸送量之間的關系
一臺(tai)混(hun)凝土輸(shu)(shu)送(song)(song)泵的(de)(de)電機功率是決定出口(kou)壓(ya)力和輸(shu)(shu)送(song)(song)方量(liang)(liang)的(de)(de)前(qian)提條件(jian),在電機功率一定的(de)(de)情(qing)況下(xia),壓(ya)力的(de)(de)升高必(bi)將使輸(shu)(shu)送(song)(song)量(liang)(liang)降(jiang)低(di);相反(fan),降(jiang)低(di)出口(kou)壓(ya)力,將會使輸(shu)(shu)送(song)(song)量(liang)(liang)增加。
為了保證混(hun)凝(ning)(ning)土輸(shu)(shu)(shu)送(song)泵既(ji)要有較(jiao)大輸(shu)(shu)(shu)送(song)量(liang),又能(neng)有一定的出(chu)(chu)口(kou)(kou)壓(ya)力(li)和與之相(xiang)匹配的經濟功(gong)(gong)率(lv)(lv),在(zai)混(hun)凝(ning)(ning)土輸(shu)(shu)(shu)送(song)泵的設(she)計中,大都采(cai)用了恒功(gong)(gong)率(lv)(lv)柱塞泵;即恒功(gong)(gong)率(lv)(lv)值選(xuan)定后(hou),當出(chu)(chu)口(kou)(kou)壓(ya)力(li)升高(gao)時(shi),油泵輸(shu)(shu)(shu)出(chu)(chu)排(pai)量(liang)會自動降低(di),達(da)到(dao)與功(gong)(gong)率(lv)(lv)設(she)計相(xiang)對應的值;如果既(ji)要達(da)到(dao)出(chu)(chu)口(kou)(kou)壓(ya)力(li)高(gao),又想(xiang)得到(dao)輸(shu)(shu)(shu)送(song)量(liang)大的目的。惟一的途(tu)徑(jing)就是(shi)增加電機功(gong)(gong)率(lv)(lv)。
因此(ci)(ci),在(zai)國家新(xin)標(biao)準中,引用(yong)了混凝土(tu)輸(shu)送泵的(de)(de)(de)(de)(de)(de)能(neng)力指(zhi)數(shu)(shu)概念(以(yi)MPa·m3/h為度量(liang)單位);即混凝土(tu)輸(shu)送泵的(de)(de)(de)(de)(de)(de)實(shi)際(ji)出(chu)口壓(ya)力與(yu)每小時實(shi)際(ji)輸(shu)送量(liang)之乘積(ji),該值越大(da),其能(neng)力指(zhi)數(shu)(shu)也越大(da),電(dian)機的(de)(de)(de)(de)(de)(de)功率(lv)也將(jiang)越大(da),由此(ci)(ci)實(shi)現大(da)排(pai)量(liang)、高揚程的(de)(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)(de)。科尼樂公司(si)在(zai)設計時,還采用(yong)了高低壓(ya)切換的(de)(de)(de)(de)(de)(de)功能(neng)設計,以(yi)滿足不同的(de)(de)(de)(de)(de)(de)施工(gong)要求,在(zai)經濟狀(zhuang)態(tai)下,又能(neng)產(chan)生(sheng)較(jiao)大(da)的(de)(de)(de)(de)(de)(de)輸(shu)送量(liang),或者以(yi)相同的(de)(de)(de)(de)(de)(de)電(dian)機功率(lv),產(chan)生(sheng)較(jiao)高的(de)(de)(de)(de)(de)(de)出(chu)口壓(ya)力。
