具體參數
隨著(zhu)現代工(gong)(gong)業(ye)的(de)(de)興(xing)起,以(yi)混(hun)凝土為主材(cai)料的(de)(de)建(jian)設方式已經成(cheng)為了(le)建(jian)筑業(ye)施工(gong)(gong)的(de)(de)主要構造之一,在各種(zhong)工(gong)(gong)程施工(gong)(gong)建(jian)設中(zhong)(zhong)占據了(le)很大(da)的(de)(de)比(bi)例,使得混(hun)凝土機(ji)械(xie)的(de)(de)發展(zhan)經久不(bu)衰,且(qie)有(you)越(yue)演越(yue)烈的(de)(de)形勢。拖式混(hun)凝土泵,簡稱拖泵,是各種(zhong)混(hun)凝土機(ji)械(xie)中(zhong)(zhong)的(de)(de)一種(zhong),用于混(hun)凝土施工(gong)(gong)中(zhong)(zhong)的(de)(de)輸送(song)和澆注工(gong)(gong)作。
拖(tuo)泵分類(lei)選型
37千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(目(mu)前(qian)國內標準混凝土泵(beng),37千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)以(yi)下為細石砂漿泵(beng))、45千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))、132千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))、174千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))等。
選擇多大電(dian)機混(hun)凝(ning)土泵,首先要考(kao)慮變壓器(qi)容量(liang),其次考(kao)慮距(ju)離(li)混(hun)凝(ning)土泵的(de)遠近和線徑大小(xiao),以免壓降(jiang)過(guo)大造成電(dian)流增高或跳閘停機,過(guo)大功率(lv)造成成本增加(jia)和使用不(bu)便。電(dian)機過(guo)小(xiao),同時也(ye)滿足不(bu)了工程需要。
混(hun)凝(ning)土輸(shu)送(song)(song)泵(beng)功率(lv)、混(hun)凝(ning)土輸(shu)送(song)(song)泵(beng)出口(kou)壓力、混(hun)凝(ning)土輸(shu)送(song)(song)泵(beng)輸(shu)送(song)(song)量(liang)之(zhi)間的(de)關(guan)系
一(yi)臺混凝土輸(shu)(shu)送(song)泵的(de)電機(ji)(ji)功率(lv)是(shi)決定出口(kou)壓力(li)(li)和輸(shu)(shu)送(song)方量(liang)的(de)前提條(tiao)件,在電機(ji)(ji)功率(lv)一(yi)定的(de)情況下,壓力(li)(li)的(de)升(sheng)高必將使(shi)輸(shu)(shu)送(song)量(liang)降(jiang)低;相反,降(jiang)低出口(kou)壓力(li)(li),將會使(shi)輸(shu)(shu)送(song)量(liang)增加。
為了保證混(hun)凝土輸(shu)(shu)送(song)泵(beng)既要有(you)較(jiao)大輸(shu)(shu)送(song)量,又(you)能有(you)一定的(de)出(chu)(chu)(chu)口(kou)壓(ya)(ya)力(li)和與之相匹配的(de)經濟功(gong)率(lv)(lv),在混(hun)凝土輸(shu)(shu)送(song)泵(beng)的(de)設計(ji)中,大都(dou)采用(yong)了恒功(gong)率(lv)(lv)柱塞(sai)泵(beng);即恒功(gong)率(lv)(lv)值(zhi)選(xuan)定后,當出(chu)(chu)(chu)口(kou)壓(ya)(ya)力(li)升高時(shi),油泵(beng)輸(shu)(shu)出(chu)(chu)(chu)排量會自(zi)動降低,達(da)到與功(gong)率(lv)(lv)設計(ji)相對應的(de)值(zhi);如果既要達(da)到出(chu)(chu)(chu)口(kou)壓(ya)(ya)力(li)高,又(you)想得到輸(shu)(shu)送(song)量大的(de)目的(de)。惟一的(de)途徑就是增加(jia)電機(ji)功(gong)率(lv)(lv)。
因此(ci),在國家新標(biao)準中,引用了混(hun)凝(ning)土(tu)輸(shu)(shu)送(song)泵的(de)(de)能力(li)指(zhi)數概念(nian)(以(yi)MPa·m3/h為度(du)量單位);即混(hun)凝(ning)土(tu)輸(shu)(shu)送(song)泵的(de)(de)實際(ji)出口壓(ya)(ya)力(li)與每小時實際(ji)輸(shu)(shu)送(song)量之乘積,該值越大(da),其能力(li)指(zhi)數也(ye)越大(da),電機(ji)的(de)(de)功率(lv)也(ye)將越大(da),由此(ci)實現大(da)排量、高揚程的(de)(de)目的(de)(de)。科尼樂公(gong)司在設計時,還采(cai)用了高低壓(ya)(ya)切換的(de)(de)功能設計,以(yi)滿足不同(tong)的(de)(de)施工要(yao)求,在經(jing)濟狀態下,又能產(chan)生較大(da)的(de)(de)輸(shu)(shu)送(song)量,或者以(yi)相同(tong)的(de)(de)電機(ji)功率(lv),產(chan)生較高的(de)(de)出口壓(ya)(ya)力(li)。
