37千(qian)(qian)(qian)瓦(wa)(wa)(wa)(目前(qian)國(guo)內標準(zhun)混凝土泵,37千(qian)(qian)(qian)瓦(wa)(wa)(wa)以(yi)下為細石砂漿泵)、45千(qian)(qian)(qian)瓦(wa)(wa)(wa)、55千(qian)(qian)(qian)瓦(wa)(wa)(wa)、75千(qian)(qian)(qian)瓦(wa)(wa)(wa)、90千(qian)(qian)(qian)瓦(wa)(wa)(wa)、110千(qian)(qian)(qian)瓦(wa)(wa)(wa)、130千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油)、132千(qian)(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油)、174千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油)等等。
選擇多大(da)(da)電(dian)機(ji)混凝土(tu)泵(beng),首先要考慮(lv)變壓(ya)器容量,其次(ci)考慮(lv)距離混凝土(tu)泵(beng)的遠近和線(xian)徑大(da)(da)小(xiao),以免壓(ya)降過(guo)大(da)(da)造(zao)成(cheng)電(dian)流增高或跳閘停機(ji),過(guo)大(da)(da)功率造(zao)成(cheng)成(cheng)本增加和使用不便。電(dian)機(ji)過(guo)小(xiao),同時也(ye)滿足不了工程需要。
混凝(ning)土輸(shu)送(song)泵功率、混凝(ning)土輸(shu)送(song)泵出口壓力(li)、混凝(ning)土輸(shu)送(song)泵輸(shu)送(song)量之間的(de)關系
一臺(tai)混凝土輸(shu)送泵的(de)(de)電機功(gong)率(lv)是決定(ding)出口(kou)壓(ya)力(li)和輸(shu)送方量的(de)(de)前提(ti)條(tiao)件,在(zai)電機功(gong)率(lv)一定(ding)的(de)(de)情況下,壓(ya)力(li)的(de)(de)升高必將使(shi)輸(shu)送量降低;相反,降低出口(kou)壓(ya)力(li),將會使(shi)輸(shu)送量增加。
為(wei)了保證混(hun)(hun)凝(ning)土輸送(song)(song)(song)泵(beng)(beng)既要有(you)較大輸送(song)(song)(song)量(liang),又能有(you)一定的出(chu)口(kou)壓(ya)力和與之相(xiang)匹配的經濟功(gong)率(lv)(lv),在(zai)混(hun)(hun)凝(ning)土輸送(song)(song)(song)泵(beng)(beng)的設(she)計(ji)中,大都采用(yong)了恒(heng)(heng)功(gong)率(lv)(lv)柱塞泵(beng)(beng);即(ji)恒(heng)(heng)功(gong)率(lv)(lv)值(zhi)選(xuan)定后,當(dang)出(chu)口(kou)壓(ya)力升高(gao)時,油(you)泵(beng)(beng)輸出(chu)排量(liang)會自動降(jiang)低,達(da)到與功(gong)率(lv)(lv)設(she)計(ji)相(xiang)對(dui)應(ying)的值(zhi);如果既要達(da)到出(chu)口(kou)壓(ya)力高(gao),又想得到輸送(song)(song)(song)量(liang)大的目(mu)的。惟一的途徑(jing)就是(shi)增加電機功(gong)率(lv)(lv)。
因(yin)此(ci),在(zai)國家新標(biao)準(zhun)中,引用了(le)(le)混(hun)凝土輸(shu)送泵的(de)能力指數概(gai)念(以(yi)MPa·m3/h為度量單位(wei));即混(hun)凝土輸(shu)送泵的(de)實際出口壓(ya)力與每小時實際輸(shu)送量之乘(cheng)積,該值越(yue)大(da)(da)(da)(da),其能力指數也越(yue)大(da)(da)(da)(da),電機(ji)的(de)功(gong)率也將(jiang)越(yue)大(da)(da)(da)(da),由此(ci)實現大(da)(da)(da)(da)排量、高(gao)揚程(cheng)的(de)目的(de)。科尼樂(le)公(gong)司在(zai)設計時,還采用了(le)(le)高(gao)低壓(ya)切換的(de)功(gong)能設計,以(yi)滿足不同(tong)(tong)的(de)施工要(yao)求,在(zai)經濟狀態下(xia),又(you)能產生較(jiao)(jiao)大(da)(da)(da)(da)的(de)輸(shu)送量,或者(zhe)以(yi)相同(tong)(tong)的(de)電機(ji)功(gong)率,產生較(jiao)(jiao)高(gao)的(de)出口壓(ya)力。
