具體參數
隨著(zhu)現代工(gong)(gong)業的(de)興(xing)起,以混(hun)(hun)凝土為主(zhu)(zhu)材料的(de)建(jian)設方式已經成(cheng)為了建(jian)筑(zhu)業施工(gong)(gong)的(de)主(zhu)(zhu)要(yao)構(gou)造之一(yi),在各種(zhong)工(gong)(gong)程施工(gong)(gong)建(jian)設中(zhong)(zhong)(zhong)占據了很大的(de)比(bi)例,使得混(hun)(hun)凝土機(ji)(ji)械的(de)發展經久不衰,且有越(yue)演越(yue)烈的(de)形勢。拖式混(hun)(hun)凝土泵,簡稱拖泵,是各種(zhong)混(hun)(hun)凝土機(ji)(ji)械中(zhong)(zhong)(zhong)的(de)一(yi)種(zhong),用于混(hun)(hun)凝土施工(gong)(gong)中(zhong)(zhong)(zhong)的(de)輸送(song)和澆注工(gong)(gong)作。
拖泵分類選型(xing)
37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(目前國內標(biao)準(zhun)混凝土泵,37千(qian)(qian)(qian)(qian)瓦(wa)(wa)以下為細石砂漿泵)、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油)、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油)、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油)等。
選擇(ze)多大(da)電(dian)(dian)機(ji)混凝(ning)土泵,首先要考慮變壓器容量,其次考慮距(ju)離混凝(ning)土泵的(de)遠近(jin)和線徑(jing)大(da)小,以免壓降過大(da)造成電(dian)(dian)流增高或跳閘(zha)停機(ji),過大(da)功率造成成本(ben)增加和使(shi)用不便(bian)。電(dian)(dian)機(ji)過小,同(tong)時(shi)也滿足不了工程需要。
混凝土(tu)輸(shu)送泵功率、混凝土(tu)輸(shu)送泵出(chu)口(kou)壓力、混凝土(tu)輸(shu)送泵輸(shu)送量之間(jian)的關系
一(yi)臺混凝土輸送泵的電(dian)機功率是決定出口壓力和輸送方量的前(qian)提條件,在電(dian)機功率一(yi)定的情(qing)況下,壓力的升(sheng)高必將使輸送量降(jiang)低;相反,降(jiang)低出口壓力,將會使輸送量增加。
為了(le)保證混(hun)凝(ning)土輸(shu)(shu)送(song)(song)(song)泵(beng)(beng)既要有較大輸(shu)(shu)送(song)(song)(song)量,又(you)能有一定的出口(kou)壓(ya)力(li)(li)和與之相匹配的經濟功率(lv),在混(hun)凝(ning)土輸(shu)(shu)送(song)(song)(song)泵(beng)(beng)的設(she)計中,大都采用(yong)了(le)恒功率(lv)柱(zhu)塞泵(beng)(beng);即恒功率(lv)值選定后,當出口(kou)壓(ya)力(li)(li)升高時,油泵(beng)(beng)輸(shu)(shu)出排量會自動降低(di),達到與功率(lv)設(she)計相對應的值;如果(guo)既要達到出口(kou)壓(ya)力(li)(li)高,又(you)想(xiang)得到輸(shu)(shu)送(song)(song)(song)量大的目的。惟一的途徑(jing)就是增加電機功率(lv)。
因此,在(zai)國家(jia)新標(biao)準中(zhong),引用了(le)混凝土(tu)輸送(song)泵(beng)的(de)能(neng)力指數(shu)概念(nian)(以(yi)MPa·m3/h為度(du)量(liang)單(dan)位(wei));即混凝土(tu)輸送(song)泵(beng)的(de)實際(ji)出口(kou)(kou)壓(ya)(ya)力與每小時實際(ji)輸送(song)量(liang)之乘積(ji),該值(zhi)越大(da),其(qi)能(neng)力指數(shu)也越大(da),電機的(de)功率也將越大(da),由此實現大(da)排量(liang)、高揚程的(de)目的(de)。科(ke)尼樂公司在(zai)設(she)計時,還采用了(le)高低壓(ya)(ya)切換(huan)的(de)功能(neng)設(she)計,以(yi)滿足不同的(de)施工(gong)要求,在(zai)經濟狀態下(xia),又(you)能(neng)產生較大(da)的(de)輸送(song)量(liang),或(huo)者以(yi)相同的(de)電機功率,產生較高的(de)出口(kou)(kou)壓(ya)(ya)力。
