37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(目前國內標(biao)準混凝土泵,37千(qian)(qian)(qian)(qian)瓦(wa)(wa)以下為細石砂漿泵)、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(dian)機混(hun)凝(ning)土(tu)泵,首先要(yao)考慮變壓(ya)器容量,其次考慮距離混(hun)凝(ning)土(tu)泵的遠近(jin)和線(xian)徑(jing)大小,以免壓(ya)降過大造成(cheng)電(dian)流(liu)增(zeng)高或(huo)跳閘停機,過大功率造成(cheng)成(cheng)本增(zeng)加和使用不(bu)便(bian)。電(dian)機過小,同(tong)時也滿足(zu)不(bu)了工程需要(yao)。
混凝土(tu)輸送(song)(song)泵(beng)功率、混凝土(tu)輸送(song)(song)泵(beng)出口壓力、混凝土(tu)輸送(song)(song)泵(beng)輸送(song)(song)量之間的(de)關系
一臺混凝土輸送泵(beng)的電(dian)機(ji)功(gong)率(lv)是決定出(chu)口(kou)壓(ya)力和輸送方量(liang)的前提(ti)條件,在電(dian)機(ji)功(gong)率(lv)一定的情況(kuang)下,壓(ya)力的升高必將(jiang)使輸送量(liang)降低;相反,降低出(chu)口(kou)壓(ya)力,將(jiang)會使輸送量(liang)增加。
為了(le)保證混(hun)(hun)凝土(tu)輸(shu)(shu)(shu)送泵既要有較大輸(shu)(shu)(shu)送量,又能(neng)有一定(ding)(ding)的(de)出(chu)口壓(ya)力和(he)與(yu)之(zhi)相(xiang)匹(pi)配的(de)經濟功(gong)率,在混(hun)(hun)凝土(tu)輸(shu)(shu)(shu)送泵的(de)設計中,大都采用了(le)恒(heng)功(gong)率柱塞泵;即恒(heng)功(gong)率值選定(ding)(ding)后,當出(chu)口壓(ya)力升高(gao)時(shi),油泵輸(shu)(shu)(shu)出(chu)排(pai)量會自動(dong)降低,達(da)到與(yu)功(gong)率設計相(xiang)對應的(de)值;如果既要達(da)到出(chu)口壓(ya)力高(gao),又想得到輸(shu)(shu)(shu)送量大的(de)目的(de)。惟一的(de)途(tu)徑就(jiu)是增加電機功(gong)率。
因(yin)此,在國家新(xin)標準中,引用了混凝土輸(shu)送(song)泵的(de)(de)(de)能力(li)(li)指數概念(以(yi)MPa·m3/h為度量單位(wei));即混凝土輸(shu)送(song)泵的(de)(de)(de)實(shi)(shi)際出口壓(ya)力(li)(li)與每(mei)小時實(shi)(shi)際輸(shu)送(song)量之乘積,該值(zhi)越大(da),其能力(li)(li)指數也越大(da),電機的(de)(de)(de)功率也將越大(da),由(you)此實(shi)(shi)現大(da)排量、高(gao)(gao)揚程(cheng)的(de)(de)(de)目(mu)的(de)(de)(de)。科尼樂公(gong)司在設(she)計(ji)時,還采用了高(gao)(gao)低(di)壓(ya)切換的(de)(de)(de)功能設(she)計(ji),以(yi)滿足不同的(de)(de)(de)施工要(yao)求,在經(jing)濟(ji)狀態下,又(you)能產生較(jiao)大(da)的(de)(de)(de)輸(shu)送(song)量,或者以(yi)相(xiang)同的(de)(de)(de)電機功率,產生較(jiao)高(gao)(gao)的(de)(de)(de)出口壓(ya)力(li)(li)。
