37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(目前國內標(biao)準混凝(ning)土泵(beng),37千(qian)(qian)(qian)(qian)瓦(wa)(wa)以下(xia)為(wei)細石砂漿泵(beng))、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(deng)等(deng)。
選(xuan)擇(ze)多大(da)電(dian)機(ji)(ji)混凝(ning)土泵,首(shou)先要考(kao)慮變壓器容量,其(qi)次考(kao)慮距(ju)離混凝(ning)土泵的遠(yuan)近和線徑大(da)小,以(yi)免壓降過(guo)大(da)造(zao)成電(dian)流增高(gao)或(huo)跳閘(zha)停機(ji)(ji),過(guo)大(da)功率造(zao)成成本增加和使(shi)用不便。電(dian)機(ji)(ji)過(guo)小,同時也滿(man)足(zu)不了工程需要。
混凝土(tu)輸送(song)(song)泵功率(lv)、混凝土(tu)輸送(song)(song)泵出口壓力(li)、混凝土(tu)輸送(song)(song)泵輸送(song)(song)量(liang)之間的關系。
一臺混凝土(tu)輸送(song)泵的(de)電(dian)機功率(lv)是決定出口(kou)壓力(li)和輸送(song)方量的(de)前提條件,在電(dian)機功率(lv)一定的(de)情況(kuang)下,壓力(li)的(de)升高必將(jiang)使輸送(song)量降低;相反,降低出口(kou)壓力(li),將(jiang)會使輸送(song)量增加。
為了(le)保(bao)證(zheng)混(hun)凝土輸(shu)(shu)送(song)泵既(ji)要有(you)(you)較(jiao)大輸(shu)(shu)送(song)量(liang),又能有(you)(you)一(yi)定的(de)出(chu)口壓(ya)(ya)力(li)(li)和與(yu)之相匹配的(de)經濟功率(lv)(lv),在混(hun)凝土輸(shu)(shu)送(song)泵的(de)設計中(zhong),大都采(cai)用了(le)恒功率(lv)(lv)柱塞泵;即(ji)恒功率(lv)(lv)值選定后,當出(chu)口壓(ya)(ya)力(li)(li)升高時,油泵輸(shu)(shu)出(chu)排量(liang)會自動(dong)降低(di),達到(dao)與(yu)功率(lv)(lv)設計相對應的(de)值;如果既(ji)要達到(dao)出(chu)口壓(ya)(ya)力(li)(li)高,又想得(de)到(dao)輸(shu)(shu)送(song)量(liang)大的(de)目的(de)。惟一(yi)的(de)途徑(jing)就是(shi)增加電(dian)機(ji)功率(lv)(lv)。
因此,在(zai)國家新標準中,引用了(le)混(hun)(hun)凝(ning)土輸(shu)送泵的能力指數概念(以MPa·m3/h為度(du)量(liang)單位);即混(hun)(hun)凝(ning)土輸(shu)送泵的實(shi)際出口(kou)壓(ya)力與每小(xiao)時實(shi)際輸(shu)送量(liang)之乘積,該值(zhi)越大(da),其能力指數也(ye)越大(da),電(dian)機的功率也(ye)將越大(da),由此實(shi)現大(da)排量(liang)、高揚(yang)程(cheng)的目的。科尼(ni)樂公司在(zai)設計時,還采用了(le)高低壓(ya)切換的功能設計,以滿足不同(tong)的施工(gong)要求,在(zai)經濟狀態(tai)下(xia),又能產(chan)生(sheng)較(jiao)(jiao)大(da)的輸(shu)送量(liang),或者以相同(tong)的電(dian)機功率,產(chan)生(sheng)較(jiao)(jiao)高的出口(kou)壓(ya)力。
