隨著現(xian)代工(gong)(gong)業(ye)的(de)(de)(de)(de)興起,以混(hun)凝(ning)(ning)(ning)土(tu)為主材料的(de)(de)(de)(de)建設方式(shi)已經成為了建筑業(ye)施工(gong)(gong)的(de)(de)(de)(de)主要構造之一,在(zai)各(ge)(ge)種(zhong)工(gong)(gong)程施工(gong)(gong)建設中(zhong)占據了很大(da)的(de)(de)(de)(de)比例,使(shi)得混(hun)凝(ning)(ning)(ning)土(tu)機械的(de)(de)(de)(de)發展經久不(bu)衰,且有(you)越(yue)演越(yue)烈的(de)(de)(de)(de)形勢。拖式(shi)混(hun)凝(ning)(ning)(ning)土(tu)泵,簡稱拖泵,是各(ge)(ge)種(zhong)混(hun)凝(ning)(ning)(ning)土(tu)機械中(zhong)的(de)(de)(de)(de)一種(zhong),用于(yu)混(hun)凝(ning)(ning)(ning)土(tu)施工(gong)(gong)中(zhong)的(de)(de)(de)(de)輸送和澆注(zhu)工(gong)(gong)作。
拖泵分類選型
37千(qian)(qian)(qian)(qian)瓦(wa)(目前國內標(biao)準混凝土泵,37千(qian)(qian)(qian)(qian)瓦(wa)以下為細石砂漿泵)、45千(qian)(qian)(qian)(qian)瓦(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(柴油)、132千(qian)(qian)(qian)(qian)瓦(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(柴油)、174千(qian)(qian)(qian)(qian)瓦(wa)(柴油)等。
選擇多大電(dian)機混(hun)凝土(tu)泵,首(shou)先要考慮(lv)(lv)變壓器(qi)容(rong)量,其次考慮(lv)(lv)距(ju)離混(hun)凝土(tu)泵的遠近和線(xian)徑大小(xiao),以免壓降過(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(yong)不便。電(dian)機過(guo)小(xiao),同時也(ye)滿足不了工程(cheng)需要。
混(hun)(hun)凝土(tu)輸(shu)(shu)送泵功率、混(hun)(hun)凝土(tu)輸(shu)(shu)送泵出口(kou)壓力、混(hun)(hun)凝土(tu)輸(shu)(shu)送泵輸(shu)(shu)送量之間(jian)的關系
一臺(tai)混凝土(tu)輸送泵的電機功率是決定出(chu)口壓力和(he)輸送方量的前提條件,在(zai)電機功率一定的情況下(xia),壓力的升(sheng)高必將(jiang)使輸送量降(jiang)低;相反,降(jiang)低出(chu)口壓力,將(jiang)會使輸送量增加。
為了(le)(le)保證混凝土輸(shu)(shu)送(song)(song)泵既(ji)(ji)要(yao)有較大(da)輸(shu)(shu)送(song)(song)量,又能(neng)有一定的(de)出(chu)口壓力(li)和與(yu)之相匹配的(de)經濟功率(lv),在混凝土輸(shu)(shu)送(song)(song)泵的(de)設(she)計中,大(da)都(dou)采用了(le)(le)恒功率(lv)柱塞泵;即恒功率(lv)值(zhi)選定后,當出(chu)口壓力(li)升高時,油泵輸(shu)(shu)出(chu)排(pai)量會自動降低,達到與(yu)功率(lv)設(she)計相對應的(de)值(zhi);如果既(ji)(ji)要(yao)達到出(chu)口壓力(li)高,又想得到輸(shu)(shu)送(song)(song)量大(da)的(de)目的(de)。惟(wei)一的(de)途(tu)徑就(jiu)是(shi)增(zeng)加(jia)電機功率(lv)。
因此,在國家新標準中,引(yin)用(yong)(yong)了(le)混凝土(tu)輸(shu)送(song)泵的(de)能力指(zhi)數概念(nian)(以(yi)MPa·m3/h為度量單位(wei));即混凝土(tu)輸(shu)送(song)泵的(de)實(shi)際出(chu)(chu)口(kou)壓(ya)力與(yu)每小(xiao)時(shi)實(shi)際輸(shu)送(song)量之乘積,該值越(yue)大(da)(da)(da)(da),其(qi)能力指(zhi)數也越(yue)大(da)(da)(da)(da),電(dian)機的(de)功率也將越(yue)大(da)(da)(da)(da),由此實(shi)現大(da)(da)(da)(da)排量、高(gao)(gao)揚(yang)程的(de)目的(de)。科尼樂公司在設計時(shi),還采用(yong)(yong)了(le)高(gao)(gao)低壓(ya)切換的(de)功能設計,以(yi)滿足(zu)不同(tong)的(de)施(shi)工要求,在經濟(ji)狀(zhuang)態(tai)下,又能產生(sheng)較大(da)(da)(da)(da)的(de)輸(shu)送(song)量,或者以(yi)相同(tong)的(de)電(dian)機功率,產生(sheng)較高(gao)(gao)的(de)出(chu)(chu)口(kou)壓(ya)力。
