37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(目前國內標準(zhun)混凝土泵(beng),37千(qian)(qian)(qian)(qian)瓦(wa)(wa)以下為細石砂漿泵(beng))、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)(chai)油(you))、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)(chai)油(you))、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)(chai)油(you))等等。
選擇多大電機(ji)混(hun)凝土(tu)泵,首先要考(kao)慮(lv)變壓(ya)器(qi)容量(liang),其次考(kao)慮(lv)距(ju)離混(hun)凝土(tu)泵的遠近和(he)線徑大小(xiao)(xiao),以免壓(ya)降過(guo)大造成電流增(zeng)高或跳(tiao)閘停機(ji),過(guo)大功(gong)率(lv)造成成本增(zeng)加和(he)使用不便。電機(ji)過(guo)小(xiao)(xiao),同時也滿足不了工程需要。
混(hun)(hun)凝(ning)土(tu)輸送(song)(song)泵功率、混(hun)(hun)凝(ning)土(tu)輸送(song)(song)泵出(chu)口壓(ya)力(li)、混(hun)(hun)凝(ning)土(tu)輸送(song)(song)泵輸送(song)(song)量之間的關系。
一臺(tai)混凝土輸(shu)送(song)(song)泵的(de)電(dian)(dian)機功(gong)(gong)率(lv)是決定出(chu)口(kou)壓(ya)力和輸(shu)送(song)(song)方量(liang)的(de)前提(ti)條件,在電(dian)(dian)機功(gong)(gong)率(lv)一定的(de)情(qing)況(kuang)下,壓(ya)力的(de)升高(gao)必將使(shi)輸(shu)送(song)(song)量(liang)降低;相反,降低出(chu)口(kou)壓(ya)力,將會(hui)使(shi)輸(shu)送(song)(song)量(liang)增加。
為了保證(zheng)混(hun)凝土輸送泵(beng)既要有較大(da)輸送量,又能有一定(ding)的(de)出(chu)(chu)(chu)口(kou)壓(ya)力和與(yu)之(zhi)相匹配的(de)經濟功率,在混(hun)凝土輸送泵(beng)的(de)設(she)計中(zhong),大(da)都采用(yong)了恒功率柱塞泵(beng);即恒功率值選定(ding)后(hou),當(dang)出(chu)(chu)(chu)口(kou)壓(ya)力升高時,油泵(beng)輸出(chu)(chu)(chu)排量會自動降低,達(da)到與(yu)功率設(she)計相對應的(de)值;如果既要達(da)到出(chu)(chu)(chu)口(kou)壓(ya)力高,又想得到輸送量大(da)的(de)目的(de)。惟一的(de)途徑就是增(zeng)加電機功率。
因此,在國家(jia)新標準中,引用了混(hun)凝土(tu)輸(shu)(shu)送(song)(song)泵的(de)(de)能(neng)力指(zhi)數概念(以MPa·m3/h為度量(liang)單位);即混(hun)凝土(tu)輸(shu)(shu)送(song)(song)泵的(de)(de)實(shi)際(ji)出口壓(ya)力與每小時實(shi)際(ji)輸(shu)(shu)送(song)(song)量(liang)之乘(cheng)積(ji),該值越大(da)(da),其能(neng)力指(zhi)數也越大(da)(da),電機(ji)的(de)(de)功率(lv)也將越大(da)(da),由此實(shi)現大(da)(da)排量(liang)、高(gao)(gao)揚程(cheng)的(de)(de)目的(de)(de)。科尼樂公司在設計(ji)時,還(huan)采用了高(gao)(gao)低壓(ya)切(qie)換的(de)(de)功能(neng)設計(ji),以滿足(zu)不同(tong)的(de)(de)施(shi)工要求(qiu),在經濟狀態下,又(you)能(neng)產(chan)生(sheng)較大(da)(da)的(de)(de)輸(shu)(shu)送(song)(song)量(liang),或者(zhe)以相同(tong)的(de)(de)電機(ji)功率(lv),產(chan)生(sheng)較高(gao)(gao)的(de)(de)出口壓(ya)力。
