37千(qian)(qian)(qian)瓦(wa)(wa)(目前(qian)國(guo)內標(biao)準混凝土(tu)泵,37千(qian)(qian)(qian)瓦(wa)(wa)以下為細石砂漿泵)、45千(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)瓦(wa)(wa)(柴油)、132千(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(柴油)、174千(qian)(qian)(qian)瓦(wa)(wa)(柴油)等等。
選擇多(duo)大(da)電機混凝土泵(beng),首先要考(kao)慮(lv)變壓器容(rong)量,其次考(kao)慮(lv)距離混凝土泵(beng)的遠近和線徑大(da)小,以免壓降過大(da)造成電流增(zeng)高(gao)或跳閘停機,過大(da)功率造成成本增(zeng)加和使用不便。電機過小,同(tong)時(shi)也(ye)滿足不了(le)工程需要。
混(hun)凝(ning)土(tu)(tu)輸(shu)送泵功率、混(hun)凝(ning)土(tu)(tu)輸(shu)送泵出口壓力、混(hun)凝(ning)土(tu)(tu)輸(shu)送泵輸(shu)送量(liang)之間的關系。
一(yi)臺混(hun)凝土輸(shu)送(song)泵(beng)的電機功率是決定出口(kou)壓(ya)(ya)(ya)力(li)和輸(shu)送(song)方量(liang)的前(qian)提條件,在電機功率一(yi)定的情況(kuang)下,壓(ya)(ya)(ya)力(li)的升高必將使(shi)輸(shu)送(song)量(liang)降低(di);相反(fan),降低(di)出口(kou)壓(ya)(ya)(ya)力(li),將會使(shi)輸(shu)送(song)量(liang)增加。
為了保證混(hun)凝土輸送(song)(song)(song)泵既要有(you)較大輸送(song)(song)(song)量,又能有(you)一定(ding)的(de)出(chu)口壓(ya)力和與(yu)(yu)之相匹配的(de)經濟功(gong)率,在混(hun)凝土輸送(song)(song)(song)泵的(de)設計(ji)(ji)中,大都采用了恒功(gong)率柱(zhu)塞(sai)泵;即恒功(gong)率值(zhi)選(xuan)定(ding)后,當出(chu)口壓(ya)力升高時,油泵輸出(chu)排量會自動降低,達(da)到(dao)與(yu)(yu)功(gong)率設計(ji)(ji)相對應的(de)值(zhi);如(ru)果(guo)既要達(da)到(dao)出(chu)口壓(ya)力高,又想得到(dao)輸送(song)(song)(song)量大的(de)目(mu)的(de)。惟一的(de)途徑就是增加電機功(gong)率。
因此,在國家新標準中,引用了混凝土輸(shu)送(song)(song)泵的(de)(de)能力(li)指數(shu)概念(以MPa·m3/h為(wei)度(du)量(liang)單位(wei));即混凝土輸(shu)送(song)(song)泵的(de)(de)實(shi)際出口(kou)壓力(li)與每小(xiao)時實(shi)際輸(shu)送(song)(song)量(liang)之乘積,該值(zhi)越大(da),其(qi)能力(li)指數(shu)也越大(da),電機的(de)(de)功(gong)(gong)率(lv)也將越大(da),由此實(shi)現大(da)排量(liang)、高(gao)揚程(cheng)的(de)(de)目的(de)(de)。科尼樂公司在設(she)計時,還采用了高(gao)低(di)壓切換的(de)(de)功(gong)(gong)能設(she)計,以滿足不同(tong)的(de)(de)施(shi)工(gong)要求(qiu),在經濟狀態(tai)下,又能產(chan)生較大(da)的(de)(de)輸(shu)送(song)(song)量(liang),或者以相同(tong)的(de)(de)電機功(gong)(gong)率(lv),產(chan)生較高(gao)的(de)(de)出口(kou)壓力(li)。
