具體參數
隨(sui)著現代(dai)工(gong)(gong)(gong)(gong)業的(de)(de)興(xing)起,以混(hun)凝土(tu)為主材料的(de)(de)建設方式已經(jing)成為了(le)建筑業施(shi)工(gong)(gong)(gong)(gong)的(de)(de)主要構造之一,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)(de)比例,使得混(hun)凝土(tu)機(ji)械的(de)(de)發(fa)展經(jing)久不衰,且有越演越烈的(de)(de)形勢。拖式混(hun)凝土(tu)泵,簡稱拖泵,是各種(zhong)混(hun)凝土(tu)機(ji)械中的(de)(de)一種(zhong),用于混(hun)凝土(tu)施(shi)工(gong)(gong)(gong)(gong)中的(de)(de)輸送(song)和澆注工(gong)(gong)(gong)(gong)作。
拖泵分類選型(xing)
37千(qian)(qian)瓦(wa)(wa)(目前國內標準混凝土泵,37千(qian)(qian)瓦(wa)(wa)以下為細石砂漿泵)、45千(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)瓦(wa)(wa)(柴油)、132千(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)瓦(wa)(wa)(柴油)、174千(qian)(qian)瓦(wa)(wa)(柴油)等。
選(xuan)擇多大電機(ji)混(hun)(hun)凝土泵,首(shou)先要考(kao)慮變(bian)壓器容量,其(qi)次(ci)考(kao)慮距離混(hun)(hun)凝土泵的(de)遠近和線徑大小,以(yi)免壓降過大造成電流增高(gao)或跳閘停機(ji),過大功率造成成本(ben)增加和使用不(bu)(bu)便。電機(ji)過小,同(tong)時也滿足不(bu)(bu)了工(gong)程需要。
混凝土輸(shu)送(song)泵(beng)功率、混凝土輸(shu)送(song)泵(beng)出口壓力(li)、混凝土輸(shu)送(song)泵(beng)輸(shu)送(song)量之間(jian)的關系(xi)
一臺混凝土(tu)輸送(song)泵的(de)(de)電(dian)機功率(lv)是(shi)決定出(chu)口壓力和輸送(song)方量(liang)的(de)(de)前(qian)提條件,在電(dian)機功率(lv)一定的(de)(de)情(qing)況下(xia),壓力的(de)(de)升高必將使輸送(song)量(liang)降低(di);相反,降低(di)出(chu)口壓力,將會使輸送(song)量(liang)增(zeng)加。
為了保(bao)證(zheng)混凝土(tu)輸(shu)(shu)送(song)(song)泵既(ji)要有較(jiao)大輸(shu)(shu)送(song)(song)量,又能有一(yi)定的(de)(de)出(chu)口(kou)(kou)壓力(li)和與(yu)之相匹(pi)配的(de)(de)經(jing)濟功(gong)率(lv),在混凝土(tu)輸(shu)(shu)送(song)(song)泵的(de)(de)設計(ji)中,大都采用了恒功(gong)率(lv)柱塞(sai)泵;即恒功(gong)率(lv)值選定后,當出(chu)口(kou)(kou)壓力(li)升高時(shi),油(you)泵輸(shu)(shu)出(chu)排量會自動降低,達到(dao)與(yu)功(gong)率(lv)設計(ji)相對應的(de)(de)值;如(ru)果(guo)既(ji)要達到(dao)出(chu)口(kou)(kou)壓力(li)高,又想得到(dao)輸(shu)(shu)送(song)(song)量大的(de)(de)目的(de)(de)。惟一(yi)的(de)(de)途(tu)徑就是增(zeng)加電(dian)機功(gong)率(lv)。
因(yin)此(ci),在(zai)國家新標(biao)準中,引用了混(hun)凝土輸(shu)(shu)送(song)泵(beng)的(de)(de)能力(li)指數概念(以(yi)MPa·m3/h為度量(liang)單位);即混(hun)凝土輸(shu)(shu)送(song)泵(beng)的(de)(de)實際出口(kou)(kou)壓(ya)力(li)與每小(xiao)時實際輸(shu)(shu)送(song)量(liang)之(zhi)乘積,該值越大(da)(da)(da),其能力(li)指數也越大(da)(da)(da),電(dian)(dian)機(ji)的(de)(de)功(gong)率也將越大(da)(da)(da),由此(ci)實現(xian)大(da)(da)(da)排(pai)量(liang)、高揚程的(de)(de)目的(de)(de)。科尼樂公司在(zai)設(she)計時,還采用了高低(di)壓(ya)切換的(de)(de)功(gong)能設(she)計,以(yi)滿足不同的(de)(de)施(shi)工要求,在(zai)經濟狀態下,又能產(chan)生(sheng)較(jiao)大(da)(da)(da)的(de)(de)輸(shu)(shu)送(song)量(liang),或者以(yi)相(xiang)同的(de)(de)電(dian)(dian)機(ji)功(gong)率,產(chan)生(sheng)較(jiao)高的(de)(de)出口(kou)(kou)壓(ya)力(li)。
