拖泵(beng)分類選型
37千(qian)(qian)(qian)瓦(wa)(目前國內(nei)標準(zhun)混(hun)凝土(tu)泵,37千(qian)(qian)(qian)瓦(wa)以下為細石砂漿泵)、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)、132千(qian)(qian)(qian)瓦(wa)、162千(qian)(qian)(qian)瓦(wa)(柴油)、174千(qian)(qian)(qian)瓦(wa)(柴油)等(deng)等(deng)。
選擇多大(da)(da)電機混(hun)凝土泵,首先要(yao)(yao)考慮變壓器(qi)容量,其次考慮距離混(hun)凝土泵的(de)遠近和線徑大(da)(da)小,以免壓降過(guo)大(da)(da)造成(cheng)電流增(zeng)高或跳閘停機,過(guo)大(da)(da)功率造成(cheng)成(cheng)本增(zeng)加和使(shi)用不便。電機過(guo)小,同(tong)時也(ye)滿足不了工程需要(yao)(yao)。
混(hun)凝(ning)土(tu)(tu)輸(shu)送(song)泵(beng)(beng)(beng)功率、混(hun)凝(ning)土(tu)(tu)輸(shu)送(song)泵(beng)(beng)(beng)出(chu)口壓(ya)力、混(hun)凝(ning)土(tu)(tu)輸(shu)送(song)泵(beng)(beng)(beng)輸(shu)送(song)量之間(jian)的關系
一臺混(hun)凝(ning)土輸送泵的(de)(de)電(dian)機(ji)功率是決定(ding)出(chu)口壓力和輸送方(fang)量的(de)(de)前提條件,在(zai)電(dian)機(ji)功率一定(ding)的(de)(de)情況(kuang)下,壓力的(de)(de)升高必(bi)將使(shi)輸送量降低(di);相反,降低(di)出(chu)口壓力,將會使(shi)輸送量增加。
為(wei)了保證(zheng)混凝(ning)(ning)土(tu)輸送泵既要(yao)(yao)有(you)(you)較大輸送量,又(you)能有(you)(you)一(yi)定(ding)的出(chu)口(kou)壓(ya)力和與之相(xiang)匹(pi)配的經濟功(gong)(gong)率(lv),在混凝(ning)(ning)土(tu)輸送泵的設(she)計(ji)(ji)中(zhong),大都采用了恒功(gong)(gong)率(lv)柱塞泵;即恒功(gong)(gong)率(lv)值選(xuan)定(ding)后(hou),當出(chu)口(kou)壓(ya)力升高時(shi),油泵輸出(chu)排量會自動降低,達到(dao)與功(gong)(gong)率(lv)設(she)計(ji)(ji)相(xiang)對應的值;如果既要(yao)(yao)達到(dao)出(chu)口(kou)壓(ya)力高,又(you)想(xiang)得(de)到(dao)輸送量大的目的。惟一(yi)的途(tu)徑(jing)就是增加電機功(gong)(gong)率(lv)。
因此,在(zai)(zai)國家新標(biao)準中(zhong),引用了(le)混凝土輸送(song)泵的(de)(de)(de)(de)能力(li)指數概念(nian)(以(yi)MPa·m3/h為度量(liang)單位);即混凝土輸送(song)泵的(de)(de)(de)(de)實(shi)際出(chu)口(kou)壓(ya)力(li)與每小時實(shi)際輸送(song)量(liang)之(zhi)乘積,該值(zhi)越(yue)大(da)(da),其能力(li)指數也越(yue)大(da)(da),電(dian)機(ji)的(de)(de)(de)(de)功(gong)(gong)率(lv)也將越(yue)大(da)(da),由此實(shi)現大(da)(da)排量(liang)、高(gao)揚程的(de)(de)(de)(de)目的(de)(de)(de)(de)。科尼樂公(gong)司(si)在(zai)(zai)設計(ji)時,還(huan)采用了(le)高(gao)低壓(ya)切換的(de)(de)(de)(de)功(gong)(gong)能設計(ji),以(yi)滿(man)足不同的(de)(de)(de)(de)施工要求,在(zai)(zai)經濟狀態(tai)下,又能產生較(jiao)(jiao)大(da)(da)的(de)(de)(de)(de)輸送(song)量(liang),或者以(yi)相(xiang)同的(de)(de)(de)(de)電(dian)機(ji)功(gong)(gong)率(lv),產生較(jiao)(jiao)高(gao)的(de)(de)(de)(de)出(chu)口(kou)壓(ya)力(li)。
