具體參數
隨著(zhu)現代工(gong)(gong)(gong)(gong)業的(de)興(xing)起(qi),以混凝土為主材料的(de)建設方式已經成為了(le)建筑業施工(gong)(gong)(gong)(gong)的(de)主要(yao)構造(zao)之(zhi)一(yi),在各(ge)(ge)種工(gong)(gong)(gong)(gong)程施工(gong)(gong)(gong)(gong)建設中(zhong)占據了(le)很(hen)大的(de)比(bi)例,使得混凝土機械的(de)發展經久不衰,且有越(yue)演越(yue)烈的(de)形勢(shi)。拖式混凝土泵,簡(jian)稱拖泵,是各(ge)(ge)種混凝土機械中(zhong)的(de)一(yi)種,用(yong)于混凝土施工(gong)(gong)(gong)(gong)中(zhong)的(de)輸送和澆注工(gong)(gong)(gong)(gong)作。
拖泵分類選(xuan)型
37千(qian)(qian)瓦(wa)(目(mu)前國內標(biao)準(zhun)混凝土(tu)泵(beng),37千(qian)(qian)瓦(wa)以下為(wei)細石砂漿泵(beng))、45千(qian)(qian)瓦(wa)、55千(qian)(qian)瓦(wa)、75千(qian)(qian)瓦(wa)、90千(qian)(qian)瓦(wa)、110千(qian)(qian)瓦(wa)、130千(qian)(qian)瓦(wa)(柴(chai)油(you))、132千(qian)(qian)瓦(wa)、162千(qian)(qian)瓦(wa)(柴(chai)油(you))、174千(qian)(qian)瓦(wa)(柴(chai)油(you))等。
選擇多大電(dian)機混凝(ning)土(tu)泵,首先要考慮(lv)變壓(ya)器容量,其次考慮(lv)距離混凝(ning)土(tu)泵的遠(yuan)近和(he)線徑大小(xiao)(xiao),以免(mian)壓(ya)降過大造成(cheng)電(dian)流(liu)增高(gao)或跳閘停機,過大功(gong)率(lv)造成(cheng)成(cheng)本增加(jia)和(he)使用(yong)不(bu)便。電(dian)機過小(xiao)(xiao),同(tong)時也滿足(zu)不(bu)了工程需要。
混(hun)凝(ning)(ning)土輸送(song)泵(beng)功率、混(hun)凝(ning)(ning)土輸送(song)泵(beng)出口壓力、混(hun)凝(ning)(ning)土輸送(song)泵(beng)輸送(song)量之間的關系
一(yi)臺混凝土輸(shu)送(song)(song)泵(beng)的(de)電機(ji)功(gong)率(lv)是決定出口壓力(li)(li)和輸(shu)送(song)(song)方量的(de)前提(ti)條件,在電機(ji)功(gong)率(lv)一(yi)定的(de)情(qing)況下,壓力(li)(li)的(de)升高必將使輸(shu)送(song)(song)量降(jiang)低;相反(fan),降(jiang)低出口壓力(li)(li),將會使輸(shu)送(song)(song)量增加。
為了保證混凝(ning)土(tu)(tu)輸(shu)送(song)(song)泵既(ji)要有較大(da)輸(shu)送(song)(song)量(liang),又能有一(yi)定的(de)(de)(de)(de)出口(kou)(kou)壓力和與之相匹配(pei)的(de)(de)(de)(de)經濟功(gong)(gong)(gong)率(lv),在混凝(ning)土(tu)(tu)輸(shu)送(song)(song)泵的(de)(de)(de)(de)設(she)計中,大(da)都采用了恒功(gong)(gong)(gong)率(lv)柱塞泵;即恒功(gong)(gong)(gong)率(lv)值選定后,當出口(kou)(kou)壓力升高時(shi),油泵輸(shu)出排量(liang)會自動降低,達(da)(da)到(dao)(dao)與功(gong)(gong)(gong)率(lv)設(she)計相對應(ying)的(de)(de)(de)(de)值;如果既(ji)要達(da)(da)到(dao)(dao)出口(kou)(kou)壓力高,又想(xiang)得到(dao)(dao)輸(shu)送(song)(song)量(liang)大(da)的(de)(de)(de)(de)目的(de)(de)(de)(de)。惟一(yi)的(de)(de)(de)(de)途徑就(jiu)是增加電機(ji)功(gong)(gong)(gong)率(lv)。
因此(ci),在(zai)國家新(xin)標(biao)準中,引用了(le)混(hun)凝土輸送泵的(de)(de)能力(li)(li)指(zhi)數(shu)概念(以MPa·m3/h為度(du)量單(dan)位);即混(hun)凝土輸送泵的(de)(de)實(shi)際出(chu)口(kou)壓(ya)(ya)力(li)(li)與(yu)每小(xiao)時實(shi)際輸送量之乘積,該值(zhi)越(yue)大(da)(da),其(qi)能力(li)(li)指(zhi)數(shu)也越(yue)大(da)(da),電機的(de)(de)功(gong)(gong)率(lv)也將越(yue)大(da)(da),由(you)此(ci)實(shi)現大(da)(da)排(pai)量、高揚(yang)程(cheng)的(de)(de)目的(de)(de)。科(ke)尼樂公司(si)在(zai)設計時,還(huan)采用了(le)高低(di)壓(ya)(ya)切換的(de)(de)功(gong)(gong)能設計,以滿(man)足不(bu)同的(de)(de)施工要求,在(zai)經(jing)濟(ji)狀態(tai)下,又能產生(sheng)較大(da)(da)的(de)(de)輸送量,或者(zhe)以相(xiang)同的(de)(de)電機功(gong)(gong)率(lv),產生(sheng)較高的(de)(de)出(chu)口(kou)壓(ya)(ya)力(li)(li)。
