37千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(目前國內標準混凝土(tu)泵(beng)(beng),37千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)以下為(wei)細石砂漿泵(beng)(beng))、45千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)油)、132千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)油)、174千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)油)等等。
選(xuan)擇多大(da)電機混凝土泵,首先要考(kao)慮變(bian)壓器容量,其次考(kao)慮距離混凝土泵的(de)遠近(jin)和線徑大(da)小,以免壓降過(guo)大(da)造成電流(liu)增高或跳閘停(ting)機,過(guo)大(da)功率(lv)造成成本增加和使用不便。電機過(guo)小,同時也滿足不了工程需要。
混凝(ning)土(tu)(tu)輸(shu)送(song)(song)泵(beng)(beng)功率、混凝(ning)土(tu)(tu)輸(shu)送(song)(song)泵(beng)(beng)出口壓力(li)、混凝(ning)土(tu)(tu)輸(shu)送(song)(song)泵(beng)(beng)輸(shu)送(song)(song)量(liang)之間的關系
一臺混凝土輸(shu)送(song)泵的(de)電機(ji)功率是決定(ding)出口壓力和輸(shu)送(song)方量的(de)前提(ti)條件,在電機(ji)功率一定(ding)的(de)情況下(xia),壓力的(de)升高必將使輸(shu)送(song)量降(jiang)(jiang)低;相反,降(jiang)(jiang)低出口壓力,將會(hui)使輸(shu)送(song)量增加。
為了保證混凝土(tu)輸(shu)送(song)泵(beng)既(ji)要有較大(da)輸(shu)送(song)量,又(you)能有一(yi)定(ding)的(de)(de)(de)出口壓(ya)力(li)和(he)與(yu)(yu)之(zhi)相匹(pi)配的(de)(de)(de)經濟功率,在混凝土(tu)輸(shu)送(song)泵(beng)的(de)(de)(de)設計(ji)中(zhong),大(da)都采用(yong)了恒功率柱(zhu)塞(sai)泵(beng);即(ji)恒功率值選(xuan)定(ding)后,當(dang)出口壓(ya)力(li)升高(gao)時,油泵(beng)輸(shu)出排量會自動降低,達(da)到(dao)與(yu)(yu)功率設計(ji)相對應(ying)的(de)(de)(de)值;如果(guo)既(ji)要達(da)到(dao)出口壓(ya)力(li)高(gao),又(you)想得到(dao)輸(shu)送(song)量大(da)的(de)(de)(de)目的(de)(de)(de)。惟一(yi)的(de)(de)(de)途徑就(jiu)是(shi)增加電機功率。
因此(ci),在(zai)國(guo)家(jia)新(xin)標準中(zhong),引用了混凝(ning)土(tu)輸(shu)送(song)泵的(de)(de)(de)能力(li)指數(shu)(shu)概念(以(yi)MPa·m3/h為度(du)量(liang)(liang)單位);即(ji)混凝(ning)土(tu)輸(shu)送(song)泵的(de)(de)(de)實際(ji)(ji)出(chu)口壓(ya)力(li)與每(mei)小(xiao)時(shi)(shi)實際(ji)(ji)輸(shu)送(song)量(liang)(liang)之乘積,該值(zhi)越(yue)大(da),其(qi)能力(li)指數(shu)(shu)也(ye)(ye)越(yue)大(da),電(dian)機的(de)(de)(de)功率(lv)也(ye)(ye)將(jiang)越(yue)大(da),由此(ci)實現大(da)排(pai)量(liang)(liang)、高揚程的(de)(de)(de)目(mu)的(de)(de)(de)。科尼樂公司在(zai)設計(ji)時(shi)(shi),還采用了高低(di)壓(ya)切換的(de)(de)(de)功能設計(ji),以(yi)滿(man)足不同(tong)的(de)(de)(de)施工(gong)要求,在(zai)經濟狀態下,又能產生(sheng)較(jiao)大(da)的(de)(de)(de)輸(shu)送(song)量(liang)(liang),或者以(yi)相同(tong)的(de)(de)(de)電(dian)機功率(lv),產生(sheng)較(jiao)高的(de)(de)(de)出(chu)口壓(ya)力(li)。
