具體參數
拖(tuo)泵分類選(xuan)型
37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(目前國(guo)內(nei)標準混凝土泵,37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)以下為細石砂漿泵)、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油(you))、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油(you))、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油(you))等等。
選擇多大(da)電(dian)機(ji)混凝(ning)土泵(beng),首先要考慮變(bian)壓(ya)(ya)器容量,其次考慮距(ju)離混凝(ning)土泵(beng)的遠(yuan)近和線(xian)徑大(da)小,以(yi)免壓(ya)(ya)降過大(da)造成電(dian)流增(zeng)高或跳閘(zha)停機(ji),過大(da)功(gong)率造成成本增(zeng)加和使用(yong)不(bu)便。電(dian)機(ji)過小,同時也滿足不(bu)了(le)工(gong)程需要。
混凝土(tu)(tu)輸送泵功(gong)率、混凝土(tu)(tu)輸送泵出口壓力、混凝土(tu)(tu)輸送泵輸送量之間的關(guan)系
一臺(tai)混凝(ning)土輸送(song)泵的(de)電機(ji)功率(lv)是決(jue)定出口壓力和輸送(song)方(fang)量(liang)的(de)前提條(tiao)件,在電機(ji)功率(lv)一定的(de)情況下(xia),壓力的(de)升高必將使輸送(song)量(liang)降低(di);相反,降低(di)出口壓力,將會使輸送(song)量(liang)增加。
為了(le)保(bao)證混(hun)凝土輸送泵(beng)既要有(you)(you)較大(da)輸送量(liang)(liang),又能有(you)(you)一定(ding)的出(chu)(chu)(chu)口(kou)壓(ya)(ya)力(li)和與之相(xiang)匹(pi)配的經濟功(gong)(gong)率(lv),在混(hun)凝土輸送泵(beng)的設計中,大(da)都(dou)采(cai)用了(le)恒功(gong)(gong)率(lv)柱塞泵(beng);即恒功(gong)(gong)率(lv)值選(xuan)定(ding)后,當出(chu)(chu)(chu)口(kou)壓(ya)(ya)力(li)升高時(shi),油泵(beng)輸出(chu)(chu)(chu)排量(liang)(liang)會自動(dong)降低,達到(dao)與功(gong)(gong)率(lv)設計相(xiang)對應的值;如果既要達到(dao)出(chu)(chu)(chu)口(kou)壓(ya)(ya)力(li)高,又想得到(dao)輸送量(liang)(liang)大(da)的目的。惟一的途(tu)徑就是(shi)增(zeng)加(jia)電(dian)機功(gong)(gong)率(lv)。
因此,在國家新標準中,引用了(le)混凝(ning)(ning)土輸(shu)送(song)(song)泵(beng)(beng)的(de)(de)(de)能力(li)指數概念(以MPa·m3/h為度量單位);即混凝(ning)(ning)土輸(shu)送(song)(song)泵(beng)(beng)的(de)(de)(de)實際(ji)出口壓力(li)與每(mei)小時(shi)實際(ji)輸(shu)送(song)(song)量之乘積(ji),該值越(yue)大(da),其(qi)能力(li)指數也越(yue)大(da),電機的(de)(de)(de)功率也將越(yue)大(da),由此實現(xian)大(da)排量、高揚程的(de)(de)(de)目的(de)(de)(de)。科尼樂公司(si)在設計(ji)時(shi),還采用了(le)高低壓切(qie)換(huan)的(de)(de)(de)功能設計(ji),以滿足不(bu)同的(de)(de)(de)施工(gong)要求,在經濟狀態下,又(you)能產(chan)生(sheng)較(jiao)大(da)的(de)(de)(de)輸(shu)送(song)(song)量,或者以相同的(de)(de)(de)電機功率,產(chan)生(sheng)較(jiao)高的(de)(de)(de)出口壓力(li)。
