具體參數
隨著現代工(gong)(gong)(gong)(gong)業(ye)的(de)興起,以混(hun)(hun)凝(ning)土(tu)(tu)為主材料的(de)建設方式(shi)已(yi)經成(cheng)為了(le)建筑業(ye)施(shi)工(gong)(gong)(gong)(gong)的(de)主要(yao)構造之(zhi)一(yi),在各種(zhong)工(gong)(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)(gong)建設中占據了(le)很大的(de)比例,使得混(hun)(hun)凝(ning)土(tu)(tu)機械的(de)發展經久不衰,且有越演越烈(lie)的(de)形(xing)勢(shi)。拖(tuo)式(shi)混(hun)(hun)凝(ning)土(tu)(tu)泵,簡稱拖(tuo)泵,是各種(zhong)混(hun)(hun)凝(ning)土(tu)(tu)機械中的(de)一(yi)種(zhong),用于混(hun)(hun)凝(ning)土(tu)(tu)施(shi)工(gong)(gong)(gong)(gong)中的(de)輸送和澆注工(gong)(gong)(gong)(gong)作。
拖泵(beng)分類選(xuan)型
37千瓦(wa)(wa)(目前國內標準混凝(ning)土泵,37千瓦(wa)(wa)以下為細石砂漿(jiang)泵)、45千瓦(wa)(wa)、55千瓦(wa)(wa)、75千瓦(wa)(wa)、90千瓦(wa)(wa)、110千瓦(wa)(wa)、130千瓦(wa)(wa)(柴油)、132千瓦(wa)(wa)、162千瓦(wa)(wa)(柴油)、174千瓦(wa)(wa)(柴油)等(deng)。
選擇多(duo)大電(dian)機混(hun)凝土泵(beng),首先(xian)要考(kao)(kao)慮變壓(ya)器容量,其次考(kao)(kao)慮距離混(hun)凝土泵(beng)的(de)遠近(jin)和線徑大小,以免壓(ya)降過大造成電(dian)流增(zeng)高或跳閘(zha)停機,過大功率造成成本增(zeng)加和使用不(bu)便。電(dian)機過小,同時也滿足不(bu)了工(gong)程需(xu)要。
混(hun)凝土輸(shu)送(song)(song)泵(beng)功率、混(hun)凝土輸(shu)送(song)(song)泵(beng)出口(kou)壓力、混(hun)凝土輸(shu)送(song)(song)泵(beng)輸(shu)送(song)(song)量(liang)之間的關系
一臺混凝土輸(shu)送泵的電(dian)機功率是決定(ding)出口(kou)壓力和輸(shu)送方量的前提條(tiao)件,在電(dian)機功率一定(ding)的情況下(xia),壓力的升高必將使(shi)輸(shu)送量降(jiang)低;相反,降(jiang)低出口(kou)壓力,將會使(shi)輸(shu)送量增加。
為了保(bao)證混凝(ning)土輸(shu)(shu)(shu)送(song)泵既要有(you)較大(da)輸(shu)(shu)(shu)送(song)量(liang),又(you)能(neng)有(you)一定(ding)的(de)出口壓(ya)力(li)和(he)與之(zhi)相(xiang)匹配的(de)經(jing)濟(ji)功(gong)(gong)率,在混凝(ning)土輸(shu)(shu)(shu)送(song)泵的(de)設(she)計中,大(da)都采用了恒(heng)功(gong)(gong)率柱(zhu)塞泵;即恒(heng)功(gong)(gong)率值選定(ding)后,當出口壓(ya)力(li)升(sheng)高時,油泵輸(shu)(shu)(shu)出排量(liang)會自動降低,達到與功(gong)(gong)率設(she)計相(xiang)對應的(de)值;如(ru)果既要達到出口壓(ya)力(li)高,又(you)想得到輸(shu)(shu)(shu)送(song)量(liang)大(da)的(de)目的(de)。惟一的(de)途徑就是增加電機功(gong)(gong)率。
因此,在(zai)國家(jia)新標(biao)準中,引用了混凝土(tu)輸(shu)(shu)(shu)(shu)送(song)泵的(de)(de)(de)(de)能(neng)力(li)指數概念(以MPa·m3/h為度量(liang)(liang)單(dan)位);即(ji)混凝土(tu)輸(shu)(shu)(shu)(shu)送(song)泵的(de)(de)(de)(de)實(shi)(shi)際出(chu)口(kou)壓力(li)與每小時(shi)(shi)實(shi)(shi)際輸(shu)(shu)(shu)(shu)送(song)量(liang)(liang)之乘積(ji),該值(zhi)越(yue)大(da),其能(neng)力(li)指數也越(yue)大(da),電機的(de)(de)(de)(de)功(gong)率(lv)也將越(yue)大(da),由此實(shi)(shi)現大(da)排量(liang)(liang)、高(gao)揚(yang)程(cheng)的(de)(de)(de)(de)目(mu)的(de)(de)(de)(de)。科尼(ni)樂公(gong)司在(zai)設(she)計(ji)時(shi)(shi),還采用了高(gao)低壓切換的(de)(de)(de)(de)功(gong)能(neng)設(she)計(ji),以滿足不同(tong)的(de)(de)(de)(de)施工(gong)要求,在(zai)經濟狀態下(xia),又(you)能(neng)產生(sheng)較大(da)的(de)(de)(de)(de)輸(shu)(shu)(shu)(shu)送(song)量(liang)(liang),或者以相同(tong)的(de)(de)(de)(de)電機功(gong)率(lv),產生(sheng)較高(gao)的(de)(de)(de)(de)出(chu)口(kou)壓力(li)。
