37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(目前國內標準混凝(ning)土泵,37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)以下為細石砂漿泵)、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴油(you))、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴油(you))、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴油(you))等(deng)等(deng)。
選擇多大(da)電機混凝土(tu)(tu)泵(beng),首先要考慮變壓器容量,其次(ci)考慮距離混凝土(tu)(tu)泵(beng)的遠近和線徑大(da)小,以免(mian)壓降過(guo)(guo)大(da)造成電流增高(gao)或跳閘停機,過(guo)(guo)大(da)功率造成成本(ben)增加和使用不便。電機過(guo)(guo)小,同時也滿足(zu)不了工(gong)程需要。
混凝(ning)(ning)土輸送(song)泵功率(lv)、混凝(ning)(ning)土輸送(song)泵出口壓力、混凝(ning)(ning)土輸送(song)泵輸送(song)量之(zhi)間的關系
一(yi)臺混(hun)凝土輸(shu)送(song)(song)泵的(de)(de)電(dian)機功率是決定出口壓(ya)力和輸(shu)送(song)(song)方量的(de)(de)前提條件(jian),在電(dian)機功率一(yi)定的(de)(de)情況下(xia),壓(ya)力的(de)(de)升(sheng)高必將(jiang)使輸(shu)送(song)(song)量降低;相反,降低出口壓(ya)力,將(jiang)會使輸(shu)送(song)(song)量增加。
為了(le)保證混(hun)凝土輸(shu)(shu)(shu)送(song)泵既要有較大輸(shu)(shu)(shu)送(song)量(liang),又能有一定的出(chu)口壓力(li)和與之(zhi)相匹(pi)配的經濟(ji)功率(lv),在(zai)混(hun)凝土輸(shu)(shu)(shu)送(song)泵的設(she)(she)計(ji)中(zhong),大都采用了(le)恒(heng)功率(lv)柱塞泵;即恒(heng)功率(lv)值選定后,當出(chu)口壓力(li)升高時,油泵輸(shu)(shu)(shu)出(chu)排(pai)量(liang)會自動降低,達到(dao)與功率(lv)設(she)(she)計(ji)相對(dui)應(ying)的值;如(ru)果既要達到(dao)出(chu)口壓力(li)高,又想得到(dao)輸(shu)(shu)(shu)送(song)量(liang)大的目的。惟一的途徑就是(shi)增加電機功率(lv)。
因此(ci)(ci),在國家新(xin)標準中,引用了混凝土輸(shu)送泵的(de)能力(li)指數(shu)概念(以(yi)MPa·m3/h為度量單位);即混凝土輸(shu)送泵的(de)實(shi)際(ji)(ji)出口(kou)壓力(li)與每小時實(shi)際(ji)(ji)輸(shu)送量之乘積,該值(zhi)越(yue)大,其能力(li)指數(shu)也越(yue)大,電機的(de)功(gong)率也將越(yue)大,由此(ci)(ci)實(shi)現大排量、高揚程的(de)目的(de)。科尼樂公(gong)司在設(she)(she)計時,還(huan)采用了高低壓切(qie)換的(de)功(gong)能設(she)(she)計,以(yi)滿(man)足不同(tong)的(de)施工(gong)要求,在經濟(ji)狀態下,又能產生較(jiao)大的(de)輸(shu)送量,或者以(yi)相同(tong)的(de)電機功(gong)率,產生較(jiao)高的(de)出口(kou)壓力(li)。
