具體參數
拖(tuo)泵(beng)分(fen)類(lei)選型
37千(qian)(qian)瓦(wa)(wa)(wa)(目前國內標準混凝土泵(beng),37千(qian)(qian)瓦(wa)(wa)(wa)以下為(wei)細石砂(sha)漿泵(beng))、45千(qian)(qian)瓦(wa)(wa)(wa)、55千(qian)(qian)瓦(wa)(wa)(wa)、75千(qian)(qian)瓦(wa)(wa)(wa)、90千(qian)(qian)瓦(wa)(wa)(wa)、110千(qian)(qian)瓦(wa)(wa)(wa)、130千(qian)(qian)瓦(wa)(wa)(wa)(柴油)、132千(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)瓦(wa)(wa)(wa)(柴油)、174千(qian)(qian)瓦(wa)(wa)(wa)(柴油)等(deng)等(deng)。
選(xuan)擇(ze)多大(da)電(dian)(dian)機混凝(ning)土泵(beng)(beng),首先(xian)要(yao)考慮變壓器容量,其次考慮距離混凝(ning)土泵(beng)(beng)的遠近和線徑(jing)大(da)小(xiao),以免壓降過大(da)造成(cheng)電(dian)(dian)流增高或跳閘停機,過大(da)功(gong)率造成(cheng)成(cheng)本增加和使(shi)用不(bu)便。電(dian)(dian)機過小(xiao),同時也滿足不(bu)了工程需(xu)要(yao)。
混(hun)凝土(tu)輸(shu)送(song)(song)泵(beng)功率、混(hun)凝土(tu)輸(shu)送(song)(song)泵(beng)出(chu)口壓力、混(hun)凝土(tu)輸(shu)送(song)(song)泵(beng)輸(shu)送(song)(song)量之(zhi)間的關系(xi)
一臺混凝土輸(shu)送(song)泵的電(dian)機(ji)功率是(shi)決(jue)定出(chu)口壓(ya)力(li)(li)和(he)輸(shu)送(song)方量(liang)的前提條件,在(zai)電(dian)機(ji)功率一定的情(qing)況(kuang)下(xia),壓(ya)力(li)(li)的升高必將(jiang)使(shi)輸(shu)送(song)量(liang)降低;相反,降低出(chu)口壓(ya)力(li)(li),將(jiang)會使(shi)輸(shu)送(song)量(liang)增加。
為了(le)(le)保(bao)證混凝土輸(shu)送泵既要(yao)有(you)較(jiao)大輸(shu)送量(liang),又能有(you)一定(ding)的(de)出口壓力(li)和與之相匹配的(de)經濟功率,在(zai)混凝土輸(shu)送泵的(de)設(she)計(ji)中,大都采用了(le)(le)恒功率柱(zhu)塞泵;即(ji)恒功率值選定(ding)后,當出口壓力(li)升高時,油泵輸(shu)出排量(liang)會(hui)自動降低(di),達(da)到(dao)與功率設(she)計(ji)相對應的(de)值;如果既要(yao)達(da)到(dao)出口壓力(li)高,又想(xiang)得(de)到(dao)輸(shu)送量(liang)大的(de)目的(de)。惟一的(de)途徑(jing)就(jiu)是(shi)增加(jia)電機(ji)功率。
因此(ci),在國家(jia)新(xin)標準中,引(yin)用(yong)了混(hun)凝土輸送(song)(song)泵(beng)的能(neng)力(li)(li)指數(shu)概(gai)念(以MPa·m3/h為度量單位);即混(hun)凝土輸送(song)(song)泵(beng)的實際出(chu)(chu)口(kou)壓(ya)力(li)(li)與每(mei)小時實際輸送(song)(song)量之乘積,該值越(yue)大(da)(da),其能(neng)力(li)(li)指數(shu)也越(yue)大(da)(da),電(dian)機的功(gong)(gong)率也將越(yue)大(da)(da),由(you)此(ci)實現大(da)(da)排量、高揚程的目的。科(ke)尼樂公(gong)司在設計時,還采用(yong)了高低(di)壓(ya)切(qie)換的功(gong)(gong)能(neng)設計,以滿足不同的施(shi)工(gong)要求,在經濟狀態(tai)下(xia),又(you)能(neng)產生(sheng)較(jiao)大(da)(da)的輸送(song)(song)量,或者以相同的電(dian)機功(gong)(gong)率,產生(sheng)較(jiao)高的出(chu)(chu)口(kou)壓(ya)力(li)(li)。
