37千(qian)(qian)(qian)瓦(wa)(wa)(wa)(目前國內標(biao)準混凝土泵,37千(qian)(qian)(qian)瓦(wa)(wa)(wa)以下為細(xi)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(you))、132千(qian)(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油(you))、174千(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴油(you))等(deng)等(deng)。
選擇多大(da)電(dian)機混(hun)(hun)凝土(tu)泵,首先(xian)要考慮變(bian)壓器容量,其次考慮距離混(hun)(hun)凝土(tu)泵的遠(yuan)近和(he)線徑大(da)小,以免壓降過(guo)大(da)造(zao)成電(dian)流增高或跳閘停機,過(guo)大(da)功率造(zao)成成本增加和(he)使用(yong)不便。電(dian)機過(guo)小,同時也滿足不了工程需要。
混凝(ning)土輸(shu)送(song)泵(beng)(beng)功率、混凝(ning)土輸(shu)送(song)泵(beng)(beng)出(chu)口壓力、混凝(ning)土輸(shu)送(song)泵(beng)(beng)輸(shu)送(song)量之間的(de)關系。
一臺混(hun)凝土輸(shu)(shu)送(song)(song)泵的電機(ji)功率是決(jue)定出(chu)口(kou)壓力(li)和輸(shu)(shu)送(song)(song)方量的前提條件(jian),在電機(ji)功率一定的情況下,壓力(li)的升高必(bi)將使(shi)輸(shu)(shu)送(song)(song)量降低;相反(fan),降低出(chu)口(kou)壓力(li),將會使(shi)輸(shu)(shu)送(song)(song)量增加。
為了保證混(hun)凝土輸送泵(beng)既要有較大輸送量,又(you)能有一(yi)定的出(chu)(chu)口(kou)(kou)壓力和與之相(xiang)匹(pi)配的經(jing)濟功率,在混(hun)凝土輸送泵(beng)的設(she)計中,大都(dou)采用了恒功率柱(zhu)塞(sai)泵(beng);即(ji)恒功率值選定后,當出(chu)(chu)口(kou)(kou)壓力升高時(shi),油泵(beng)輸出(chu)(chu)排(pai)量會(hui)自動降低,達到與功率設(she)計相(xiang)對應的值;如果既要達到出(chu)(chu)口(kou)(kou)壓力高,又(you)想得到輸送量大的目的。惟一(yi)的途徑就是增加電機(ji)功率。
因(yin)此(ci)(ci),在國家新標準中,引用了混凝土(tu)輸(shu)送泵的能力(li)(li)(li)(li)指數概念(以(yi)MPa·m3/h為度(du)量單位);即混凝土(tu)輸(shu)送泵的實(shi)際出口(kou)壓力(li)(li)(li)(li)與每小時(shi)實(shi)際輸(shu)送量之乘積(ji),該值(zhi)越(yue)大(da),其能力(li)(li)(li)(li)指數也越(yue)大(da),電機的功(gong)率(lv)也將越(yue)大(da),由此(ci)(ci)實(shi)現(xian)大(da)排量、高(gao)(gao)揚程的目的。科尼樂公(gong)司在設(she)計(ji)時(shi),還采用了高(gao)(gao)低壓切換的功(gong)能設(she)計(ji),以(yi)滿足不同(tong)的施工(gong)要求,在經(jing)濟狀態下,又能產(chan)生較(jiao)大(da)的輸(shu)送量,或者以(yi)相(xiang)同(tong)的電機功(gong)率(lv),產(chan)生較(jiao)高(gao)(gao)的出口(kou)壓力(li)(li)(li)(li)。
