拖(tuo)泵分類(lei)選型(xing)
37千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(目(mu)前國內標準混凝土泵,37千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)以下為細(xi)石(shi)砂漿泵)、45千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、55千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、75千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、90千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、110千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、130千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油)、132千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油)、174千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油)等等。
選擇(ze)多大電(dian)機混(hun)凝(ning)土(tu)泵,首先要(yao)(yao)考(kao)慮變(bian)壓器容量,其次考(kao)慮距(ju)離混(hun)凝(ning)土(tu)泵的遠近和線(xian)徑大小,以免壓降(jiang)過大造成電(dian)流增高或(huo)跳閘(zha)停機,過大功率造成成本增加和使用(yong)不便。電(dian)機過小,同(tong)時也滿足(zu)不了工程需要(yao)(yao)。
混凝(ning)土輸(shu)送(song)泵(beng)功(gong)率、混凝(ning)土輸(shu)送(song)泵(beng)出口壓力、混凝(ning)土輸(shu)送(song)泵(beng)輸(shu)送(song)量之間(jian)的(de)關系
一(yi)(yi)臺混凝土輸送(song)泵的(de)電(dian)機(ji)功(gong)率是(shi)決定出口(kou)壓(ya)力(li)和輸送(song)方量(liang)(liang)的(de)前(qian)提條件,在電(dian)機(ji)功(gong)率一(yi)(yi)定的(de)情況下,壓(ya)力(li)的(de)升高(gao)必將使(shi)輸送(song)量(liang)(liang)降(jiang)低;相(xiang)反,降(jiang)低出口(kou)壓(ya)力(li),將會使(shi)輸送(song)量(liang)(liang)增(zeng)加。
為(wei)了保證混凝(ning)土輸(shu)送泵(beng)既要有較大輸(shu)送量,又(you)(you)能有一定(ding)(ding)的出口壓(ya)(ya)力和與之相匹配的經濟功率(lv),在混凝(ning)土輸(shu)送泵(beng)的設(she)計中(zhong),大都(dou)采用了恒功率(lv)柱塞泵(beng);即(ji)恒功率(lv)值選(xuan)定(ding)(ding)后,當(dang)出口壓(ya)(ya)力升高時,油泵(beng)輸(shu)出排量會自(zi)動降低,達到(dao)(dao)與功率(lv)設(she)計相對應的值;如果既要達到(dao)(dao)出口壓(ya)(ya)力高,又(you)(you)想得到(dao)(dao)輸(shu)送量大的目的。惟一的途(tu)徑(jing)就是增加(jia)電機功率(lv)。
因此(ci),在(zai)(zai)國家新標準中,引用(yong)了混凝土輸送(song)(song)泵的(de)(de)(de)能力(li)(li)指(zhi)數概念(nian)(以MPa·m3/h為(wei)度量(liang)(liang)單位);即混凝土輸送(song)(song)泵的(de)(de)(de)實(shi)際出(chu)口壓(ya)力(li)(li)與每(mei)小時(shi)(shi)實(shi)際輸送(song)(song)量(liang)(liang)之乘積,該(gai)值越大(da),其能力(li)(li)指(zhi)數也(ye)越大(da),電(dian)機的(de)(de)(de)功(gong)率(lv)也(ye)將越大(da),由此(ci)實(shi)現大(da)排(pai)量(liang)(liang)、高(gao)揚程的(de)(de)(de)目的(de)(de)(de)。科尼樂公司在(zai)(zai)設計(ji)時(shi)(shi),還采用(yong)了高(gao)低壓(ya)切換(huan)的(de)(de)(de)功(gong)能設計(ji),以滿足不同(tong)的(de)(de)(de)施工要求,在(zai)(zai)經濟狀(zhuang)態下(xia),又能產生較大(da)的(de)(de)(de)輸送(song)(song)量(liang)(liang),或者以相同(tong)的(de)(de)(de)電(dian)機功(gong)率(lv),產生較高(gao)的(de)(de)(de)出(chu)口壓(ya)力(li)(li)。
