具體參數
隨(sui)著現代工(gong)(gong)(gong)業的(de)(de)興(xing)起(qi),以混凝(ning)(ning)土為(wei)主材(cai)料的(de)(de)建設方式(shi)已經成(cheng)為(wei)了建筑業施工(gong)(gong)(gong)的(de)(de)主要構造(zao)之一,在各種(zhong)工(gong)(gong)(gong)程施工(gong)(gong)(gong)建設中占(zhan)據了很大的(de)(de)比(bi)例,使得混凝(ning)(ning)土機(ji)械的(de)(de)發展經久(jiu)不衰(shuai),且有越演越烈的(de)(de)形勢。拖式(shi)混凝(ning)(ning)土泵(beng),簡(jian)稱拖泵(beng),是各種(zhong)混凝(ning)(ning)土機(ji)械中的(de)(de)一種(zhong),用于(yu)混凝(ning)(ning)土施工(gong)(gong)(gong)中的(de)(de)輸送和(he)澆(jiao)注(zhu)工(gong)(gong)(gong)作。
拖泵分類(lei)選型
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)以下(xia)為細石(shi)砂漿泵(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)(柴油)、132千(qian)(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油)、174千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油)等。
選擇多大電機混凝(ning)土泵(beng),首先要(yao)考慮變壓器(qi)容量(liang),其(qi)次(ci)考慮距離混凝(ning)土泵(beng)的遠近和線徑大小(xiao)(xiao),以免壓降過(guo)大造成(cheng)電流增(zeng)高或跳閘停機,過(guo)大功率造成(cheng)成(cheng)本增(zeng)加和使用不便。電機過(guo)小(xiao)(xiao),同(tong)時也滿足不了工程需要(yao)。
混(hun)凝土(tu)輸(shu)(shu)送(song)泵功率、混(hun)凝土(tu)輸(shu)(shu)送(song)泵出口壓力(li)、混(hun)凝土(tu)輸(shu)(shu)送(song)泵輸(shu)(shu)送(song)量之間的關系
一(yi)臺混凝土輸(shu)送泵的(de)(de)電機功(gong)率是決定(ding)出口壓力和輸(shu)送方量的(de)(de)前提條件,在電機功(gong)率一(yi)定(ding)的(de)(de)情況下,壓力的(de)(de)升高必將使輸(shu)送量降(jiang)低;相反,降(jiang)低出口壓力,將會使輸(shu)送量增(zeng)加。
為(wei)了保(bao)證混凝土(tu)輸(shu)送(song)(song)(song)泵(beng)既(ji)要有較(jiao)大輸(shu)送(song)(song)(song)量(liang),又能有一定的(de)出口(kou)(kou)壓(ya)力(li)和與之相匹配(pei)的(de)經(jing)濟(ji)功(gong)(gong)率(lv),在混凝土(tu)輸(shu)送(song)(song)(song)泵(beng)的(de)設(she)計(ji)中,大都采用(yong)了恒功(gong)(gong)率(lv)柱塞(sai)泵(beng);即恒功(gong)(gong)率(lv)值(zhi)選定后,當出口(kou)(kou)壓(ya)力(li)升高時,油(you)泵(beng)輸(shu)出排量(liang)會自動降低(di),達到(dao)與功(gong)(gong)率(lv)設(she)計(ji)相對應的(de)值(zhi);如果既(ji)要達到(dao)出口(kou)(kou)壓(ya)力(li)高,又想得到(dao)輸(shu)送(song)(song)(song)量(liang)大的(de)目的(de)。惟一的(de)途徑就是增加電機功(gong)(gong)率(lv)。
因此,在(zai)國家新(xin)標(biao)準中,引(yin)用了混凝土輸送(song)泵(beng)的(de)(de)(de)能力(li)(li)指數概念(以MPa·m3/h為度量單位);即混凝土輸送(song)泵(beng)的(de)(de)(de)實(shi)際出(chu)口壓(ya)力(li)(li)與每(mei)小時實(shi)際輸送(song)量之乘(cheng)積,該值越大(da),其能力(li)(li)指數也越大(da),電(dian)機的(de)(de)(de)功率也將越大(da),由此實(shi)現大(da)排量、高(gao)揚程的(de)(de)(de)目的(de)(de)(de)。科尼樂(le)公司在(zai)設計時,還采用了高(gao)低(di)壓(ya)切換(huan)的(de)(de)(de)功能設計,以滿足不同(tong)的(de)(de)(de)施工要求,在(zai)經濟狀態下(xia),又能產生較大(da)的(de)(de)(de)輸送(song)量,或者以相同(tong)的(de)(de)(de)電(dian)機功率,產生較高(gao)的(de)(de)(de)出(chu)口壓(ya)力(li)(li)。
