具體參數
隨著現代(dai)工(gong)(gong)業的(de)(de)(de)(de)興起,以混(hun)(hun)凝(ning)(ning)(ning)土(tu)(tu)(tu)為(wei)主材料的(de)(de)(de)(de)建(jian)設方式(shi)(shi)已經成為(wei)了建(jian)筑業施(shi)工(gong)(gong)的(de)(de)(de)(de)主要構造(zao)之一(yi),在各種(zhong)工(gong)(gong)程施(shi)工(gong)(gong)建(jian)設中(zhong)(zhong)占據了很(hen)大的(de)(de)(de)(de)比例,使得混(hun)(hun)凝(ning)(ning)(ning)土(tu)(tu)(tu)機(ji)械(xie)的(de)(de)(de)(de)發(fa)展(zhan)經久不衰(shuai),且有越演越烈的(de)(de)(de)(de)形勢(shi)。拖式(shi)(shi)混(hun)(hun)凝(ning)(ning)(ning)土(tu)(tu)(tu)泵,簡稱拖泵,是各種(zhong)混(hun)(hun)凝(ning)(ning)(ning)土(tu)(tu)(tu)機(ji)械(xie)中(zhong)(zhong)的(de)(de)(de)(de)一(yi)種(zhong),用于混(hun)(hun)凝(ning)(ning)(ning)土(tu)(tu)(tu)施(shi)工(gong)(gong)中(zhong)(zhong)的(de)(de)(de)(de)輸送和澆注(zhu)工(gong)(gong)作(zuo)。
拖泵分類選型
37千(qian)(qian)(qian)瓦(wa)(wa)(目前國(guo)內標準混凝土泵,37千(qian)(qian)(qian)瓦(wa)(wa)以下為細石砂漿(jiang)泵)、45千(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))、132千(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))、174千(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))等。
選擇多大電機混凝土泵,首先要考慮變壓器容量,其次考慮距離混凝土泵的遠近和線徑(jing)大小(xiao)(xiao),以免壓降過(guo)大造(zao)成電流增(zeng)高或跳閘停機,過(guo)大功率造(zao)成成本(ben)增(zeng)加(jia)和使(shi)用不(bu)便。電機過(guo)小(xiao)(xiao),同(tong)時也滿足不(bu)了工程(cheng)需要。
混(hun)凝(ning)土輸送(song)泵(beng)(beng)功(gong)率、混(hun)凝(ning)土輸送(song)泵(beng)(beng)出口(kou)壓力(li)、混(hun)凝(ning)土輸送(song)泵(beng)(beng)輸送(song)量之間的關系
一臺混(hun)凝(ning)土(tu)輸送(song)泵(beng)的(de)電機(ji)功(gong)率(lv)是決定(ding)出口(kou)壓力和輸送(song)方量的(de)前提條(tiao)件,在電機(ji)功(gong)率(lv)一定(ding)的(de)情況(kuang)下,壓力的(de)升高(gao)必(bi)將(jiang)使輸送(song)量降低;相反,降低出口(kou)壓力,將(jiang)會使輸送(song)量增(zeng)加(jia)。
為(wei)了保證混凝土輸(shu)(shu)送泵(beng)既(ji)要有(you)較大輸(shu)(shu)送量(liang),又(you)能有(you)一定(ding)的(de)出(chu)(chu)口(kou)壓(ya)(ya)力(li)和與之相匹配的(de)經濟功率(lv),在混凝土輸(shu)(shu)送泵(beng)的(de)設(she)計中(zhong),大都采用了恒(heng)功率(lv)柱(zhu)塞泵(beng);即恒(heng)功率(lv)值(zhi)選(xuan)定(ding)后,當出(chu)(chu)口(kou)壓(ya)(ya)力(li)升高時,油泵(beng)輸(shu)(shu)出(chu)(chu)排量(liang)會自動(dong)降低,達到與功率(lv)設(she)計相對(dui)應的(de)值(zhi);如果既(ji)要達到出(chu)(chu)口(kou)壓(ya)(ya)力(li)高,又(you)想得(de)到輸(shu)(shu)送量(liang)大的(de)目的(de)。惟一的(de)途徑就是增(zeng)加電機功率(lv)。
因此(ci),在國家新標準中(zhong),引用了混凝(ning)土輸送(song)(song)(song)(song)泵的(de)能(neng)(neng)(neng)力指數(shu)概念(以(yi)MPa·m3/h為度量單位);即混凝(ning)土輸送(song)(song)(song)(song)泵的(de)實(shi)際(ji)出口壓(ya)(ya)力與每小時(shi)(shi)實(shi)際(ji)輸送(song)(song)(song)(song)量之乘(cheng)積(ji),該值越大,其能(neng)(neng)(neng)力指數(shu)也越大,電(dian)機的(de)功率也將越大,由此(ci)實(shi)現大排量、高(gao)揚程的(de)目的(de)。科尼樂公司在設計(ji)時(shi)(shi),還采用了高(gao)低壓(ya)(ya)切換(huan)的(de)功能(neng)(neng)(neng)設計(ji),以(yi)滿足不同的(de)施工(gong)要求(qiu),在經濟狀(zhuang)態下,又能(neng)(neng)(neng)產(chan)生較大的(de)輸送(song)(song)(song)(song)量,或者以(yi)相同的(de)電(dian)機功率,產(chan)生較高(gao)的(de)出口壓(ya)(ya)力。
