具體參數
隨著現代工(gong)業的(de)(de)(de)興起(qi),以混(hun)凝(ning)土為主材料的(de)(de)(de)建(jian)設方式已經成為了(le)建(jian)筑業施(shi)工(gong)的(de)(de)(de)主要構造之一,在(zai)各種工(gong)程(cheng)施(shi)工(gong)建(jian)設中(zhong)占據了(le)很大的(de)(de)(de)比例,使(shi)得混(hun)凝(ning)土機械(xie)的(de)(de)(de)發展經久不(bu)衰(shuai),且有越演越烈的(de)(de)(de)形勢。拖(tuo)式混(hun)凝(ning)土泵(beng),簡稱拖(tuo)泵(beng),是各種混(hun)凝(ning)土機械(xie)中(zhong)的(de)(de)(de)一種,用于(yu)混(hun)凝(ning)土施(shi)工(gong)中(zhong)的(de)(de)(de)輸送和澆注工(gong)作(zuo)。
拖泵(beng)分類選型(xing)
37千(qian)(qian)(qian)瓦(wa)(wa)(wa)(目前國(guo)內標準混凝土泵(beng),37千(qian)(qian)(qian)瓦(wa)(wa)(wa)以(yi)下為(wei)細(xi)石砂漿(jiang)泵(beng))、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(da)(da)電(dian)(dian)機(ji)(ji)混凝土泵(beng),首先要考慮變壓器(qi)容(rong)量,其(qi)次考慮距離混凝土泵(beng)的遠近和(he)線徑大(da)(da)小,以免(mian)壓降過(guo)大(da)(da)造成(cheng)電(dian)(dian)流(liu)增高或跳(tiao)閘停(ting)機(ji)(ji),過(guo)大(da)(da)功率造成(cheng)成(cheng)本增加和(he)使(shi)用(yong)不(bu)便(bian)。電(dian)(dian)機(ji)(ji)過(guo)小,同時也滿足(zu)不(bu)了工程需要。
混(hun)凝土(tu)輸(shu)送泵(beng)(beng)功(gong)率、混(hun)凝土(tu)輸(shu)送泵(beng)(beng)出口壓力、混(hun)凝土(tu)輸(shu)送泵(beng)(beng)輸(shu)送量之間的關系
一臺混凝土輸(shu)送泵的電(dian)機功率(lv)是決定(ding)出(chu)口(kou)壓(ya)力和(he)輸(shu)送方量(liang)的前提條(tiao)件,在電(dian)機功率(lv)一定(ding)的情況(kuang)下,壓(ya)力的升高必將使輸(shu)送量(liang)降低(di);相(xiang)反,降低(di)出(chu)口(kou)壓(ya)力,將會使輸(shu)送量(liang)增(zeng)加。
為了保證混凝土(tu)(tu)輸(shu)送(song)(song)(song)泵(beng)(beng)既要有(you)較大(da)輸(shu)送(song)(song)(song)量(liang),又(you)能有(you)一定的出口(kou)壓力和(he)與(yu)之相(xiang)匹配的經濟功(gong)率(lv),在(zai)混凝土(tu)(tu)輸(shu)送(song)(song)(song)泵(beng)(beng)的設計中,大(da)都采用了恒功(gong)率(lv)柱塞(sai)泵(beng)(beng);即恒功(gong)率(lv)值選定后,當出口(kou)壓力升高(gao)時,油泵(beng)(beng)輸(shu)出排量(liang)會自動(dong)降低(di),達到與(yu)功(gong)率(lv)設計相(xiang)對應的值;如果(guo)既要達到出口(kou)壓力高(gao),又(you)想得到輸(shu)送(song)(song)(song)量(liang)大(da)的目的。惟一的途徑就是(shi)增加(jia)電(dian)機功(gong)率(lv)。
因此,在(zai)國家新標(biao)準(zhun)中(zhong),引用(yong)(yong)了混(hun)凝土(tu)輸(shu)(shu)送泵(beng)的(de)能(neng)(neng)力指(zhi)數概念(以MPa·m3/h為度量(liang)單(dan)位);即混(hun)凝土(tu)輸(shu)(shu)送泵(beng)的(de)實際(ji)出口壓力與每(mei)小時實際(ji)輸(shu)(shu)送量(liang)之(zhi)乘(cheng)積,該值越大,其能(neng)(neng)力指(zhi)數也越大,電(dian)機的(de)功率也將越大,由此實現大排量(liang)、高揚(yang)程的(de)目的(de)。科(ke)尼樂公(gong)司(si)在(zai)設計(ji)時,還采用(yong)(yong)了高低壓切換的(de)功能(neng)(neng)設計(ji),以滿足不同的(de)施(shi)工要求,在(zai)經濟(ji)狀態下,又能(neng)(neng)產(chan)生(sheng)較大的(de)輸(shu)(shu)送量(liang),或者以相同的(de)電(dian)機功率,產(chan)生(sheng)較高的(de)出口壓力。
