37千(qian)(qian)(qian)瓦(wa)(目前國內標(biao)準(zhun)混凝土泵,37千(qian)(qian)(qian)瓦(wa)以下為(wei)細石砂(sha)漿(jiang)泵)、45千(qian)(qian)(qian)瓦(wa)、55千(qian)(qian)(qian)瓦(wa)、75千(qian)(qian)(qian)瓦(wa)、90千(qian)(qian)(qian)瓦(wa)、110千(qian)(qian)(qian)瓦(wa)、130千(qian)(qian)(qian)瓦(wa)(柴油(you))、132千(qian)(qian)(qian)瓦(wa)、162千(qian)(qian)(qian)瓦(wa)(柴油(you))、174千(qian)(qian)(qian)瓦(wa)(柴油(you))等等。
選擇多大(da)電(dian)機(ji)混(hun)凝(ning)土泵,首(shou)先要考慮變(bian)壓器容量,其次考慮距離混(hun)凝(ning)土泵的遠近和(he)線徑(jing)大(da)小,以免壓降(jiang)過(guo)大(da)造(zao)成(cheng)電(dian)流增(zeng)高或跳閘停機(ji),過(guo)大(da)功率造(zao)成(cheng)成(cheng)本增(zeng)加和(he)使用不(bu)便。電(dian)機(ji)過(guo)小,同時也(ye)滿足不(bu)了工(gong)程需要。
混凝土(tu)(tu)輸(shu)送(song)(song)泵(beng)功率、混凝土(tu)(tu)輸(shu)送(song)(song)泵(beng)出口(kou)壓力、混凝土(tu)(tu)輸(shu)送(song)(song)泵(beng)輸(shu)送(song)(song)量之間的關系
一臺混凝(ning)土輸(shu)送(song)泵(beng)的電(dian)(dian)機功率是決定出口壓力和輸(shu)送(song)方量的前提條件,在電(dian)(dian)機功率一定的情況下,壓力的升高必將使(shi)輸(shu)送(song)量降低;相反(fan),降低出口壓力,將會使(shi)輸(shu)送(song)量增加。
為了(le)保證混凝土輸(shu)(shu)送(song)泵(beng)既要(yao)有(you)較大(da)(da)輸(shu)(shu)送(song)量,又能有(you)一定(ding)的(de)出口壓(ya)力(li)和與之相(xiang)(xiang)匹配的(de)經濟功(gong)率(lv)(lv),在(zai)混凝土輸(shu)(shu)送(song)泵(beng)的(de)設計中,大(da)(da)都采用了(le)恒(heng)功(gong)率(lv)(lv)柱塞泵(beng);即恒(heng)功(gong)率(lv)(lv)值選定(ding)后(hou),當出口壓(ya)力(li)升高時,油泵(beng)輸(shu)(shu)出排(pai)量會自動降低(di),達到與功(gong)率(lv)(lv)設計相(xiang)(xiang)對應的(de)值;如果(guo)既要(yao)達到出口壓(ya)力(li)高,又想得到輸(shu)(shu)送(song)量大(da)(da)的(de)目的(de)。惟一的(de)途徑就是(shi)增加(jia)電(dian)機功(gong)率(lv)(lv)。
因(yin)此(ci),在(zai)國家新(xin)標準中(zhong),引用了混(hun)凝土(tu)輸(shu)(shu)送(song)泵的(de)(de)(de)能力指數概(gai)念(以MPa·m3/h為度量(liang)(liang)單位);即混(hun)凝土(tu)輸(shu)(shu)送(song)泵的(de)(de)(de)實際出口壓力與每小時(shi)實際輸(shu)(shu)送(song)量(liang)(liang)之乘積,該值越(yue)(yue)大(da)(da),其能力指數也越(yue)(yue)大(da)(da),電(dian)(dian)機的(de)(de)(de)功率(lv)也將越(yue)(yue)大(da)(da),由此(ci)實現大(da)(da)排量(liang)(liang)、高(gao)(gao)揚程的(de)(de)(de)目的(de)(de)(de)。科尼樂公司在(zai)設計時(shi),還(huan)采(cai)用了高(gao)(gao)低壓切換的(de)(de)(de)功能設計,以滿足不同(tong)的(de)(de)(de)施工要求,在(zai)經濟狀態(tai)下(xia),又能產生較(jiao)大(da)(da)的(de)(de)(de)輸(shu)(shu)送(song)量(liang)(liang),或者以相同(tong)的(de)(de)(de)電(dian)(dian)機功率(lv),產生較(jiao)高(gao)(gao)的(de)(de)(de)出口壓力。
