37千(qian)(qian)瓦(wa)(wa)(wa)(wa)(目前國內標準(zhun)混凝(ning)土泵,37千(qian)(qian)瓦(wa)(wa)(wa)(wa)以下為(wei)細石砂漿泵)、45千(qian)(qian)瓦(wa)(wa)(wa)(wa)、55千(qian)(qian)瓦(wa)(wa)(wa)(wa)、75千(qian)(qian)瓦(wa)(wa)(wa)(wa)、90千(qian)(qian)瓦(wa)(wa)(wa)(wa)、110千(qian)(qian)瓦(wa)(wa)(wa)(wa)、130千(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)油)、132千(qian)(qian)瓦(wa)(wa)(wa)(wa)、162千(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)油)、174千(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)油)等等。
選擇多(duo)大(da)電機混凝(ning)土泵,首(shou)先要考(kao)慮變(bian)壓(ya)器容量,其次考(kao)慮距離混凝(ning)土泵的遠近和(he)線(xian)徑(jing)大(da)小(xiao),以免壓(ya)降過大(da)造(zao)成電流增(zeng)高或跳閘停機,過大(da)功率造(zao)成成本增(zeng)加(jia)和(he)使用不(bu)便。電機過小(xiao),同時也滿足不(bu)了工程需要。
混(hun)(hun)凝(ning)土輸送(song)(song)泵(beng)功率(lv)、混(hun)(hun)凝(ning)土輸送(song)(song)泵(beng)出(chu)口壓力、混(hun)(hun)凝(ning)土輸送(song)(song)泵(beng)輸送(song)(song)量(liang)之間(jian)的關系。
一(yi)臺混凝土輸(shu)(shu)送(song)泵的(de)(de)電(dian)機(ji)功(gong)率是決定(ding)出口(kou)壓(ya)力和輸(shu)(shu)送(song)方(fang)量的(de)(de)前提條件,在電(dian)機(ji)功(gong)率一(yi)定(ding)的(de)(de)情況下,壓(ya)力的(de)(de)升高(gao)必將使輸(shu)(shu)送(song)量降低;相反(fan),降低出口(kou)壓(ya)力,將會(hui)使輸(shu)(shu)送(song)量增加。
為了(le)保證混凝土(tu)(tu)輸(shu)送(song)泵(beng)既(ji)要(yao)有較大輸(shu)送(song)量,又(you)能有一定的(de)(de)出口壓(ya)力(li)和與(yu)(yu)之相(xiang)匹配(pei)的(de)(de)經(jing)濟功率(lv)(lv),在混凝土(tu)(tu)輸(shu)送(song)泵(beng)的(de)(de)設計(ji)中,大都采用(yong)了(le)恒(heng)功率(lv)(lv)柱塞泵(beng);即恒(heng)功率(lv)(lv)值選定后,當出口壓(ya)力(li)升高時,油泵(beng)輸(shu)出排量會自(zi)動降低,達(da)(da)到與(yu)(yu)功率(lv)(lv)設計(ji)相(xiang)對應的(de)(de)值;如(ru)果(guo)既(ji)要(yao)達(da)(da)到出口壓(ya)力(li)高,又(you)想得到輸(shu)送(song)量大的(de)(de)目(mu)的(de)(de)。惟一的(de)(de)途徑就是(shi)增加電(dian)機功率(lv)(lv)。
因(yin)此(ci),在(zai)國家(jia)新標準(zhun)中,引(yin)用(yong)了混(hun)凝(ning)(ning)土(tu)輸(shu)(shu)送(song)(song)泵(beng)的能(neng)(neng)力指數(shu)(shu)概(gai)念(nian)(以MPa·m3/h為度(du)量(liang)單位);即混(hun)凝(ning)(ning)土(tu)輸(shu)(shu)送(song)(song)泵(beng)的實(shi)際(ji)出口壓(ya)(ya)力與每小時實(shi)際(ji)輸(shu)(shu)送(song)(song)量(liang)之乘積,該值越(yue)大(da),其能(neng)(neng)力指數(shu)(shu)也(ye)(ye)越(yue)大(da),電(dian)機(ji)的功率也(ye)(ye)將越(yue)大(da),由此(ci)實(shi)現大(da)排量(liang)、高揚程的目的。科尼(ni)樂公(gong)司在(zai)設計時,還采用(yong)了高低壓(ya)(ya)切換的功能(neng)(neng)設計,以滿足不同的施工要求(qiu),在(zai)經濟(ji)狀態(tai)下,又能(neng)(neng)產生較大(da)的輸(shu)(shu)送(song)(song)量(liang),或者以相(xiang)同的電(dian)機(ji)功率,產生較高的出口壓(ya)(ya)力。
