37千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(目前國內標準混凝土泵(beng)(beng),37千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)以下為細石砂漿泵(beng)(beng))、45千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油)、132千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油)、174千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油)等等。
選擇多大電機混(hun)凝土(tu)泵,首先要考慮(lv)變壓器容量(liang),其(qi)次考慮(lv)距離混(hun)凝土(tu)泵的遠近(jin)和(he)(he)線(xian)徑(jing)大小,以免壓降過(guo)大造(zao)成(cheng)(cheng)電流增高或跳閘停(ting)機,過(guo)大功(gong)率(lv)造(zao)成(cheng)(cheng)成(cheng)(cheng)本增加和(he)(he)使(shi)用不(bu)便。電機過(guo)小,同時也滿足(zu)不(bu)了工程需要。
混(hun)(hun)凝土(tu)輸送(song)泵功率、混(hun)(hun)凝土(tu)輸送(song)泵出口壓力、混(hun)(hun)凝土(tu)輸送(song)泵輸送(song)量(liang)之間的關(guan)系
一臺混凝土(tu)輸(shu)(shu)送(song)泵的電機功(gong)率是決定(ding)出口壓(ya)力和輸(shu)(shu)送(song)方量(liang)的前提(ti)條件,在電機功(gong)率一定(ding)的情(qing)況(kuang)下,壓(ya)力的升高必將使輸(shu)(shu)送(song)量(liang)降低;相反,降低出口壓(ya)力,將會使輸(shu)(shu)送(song)量(liang)增加(jia)。
為了保(bao)證混凝土(tu)(tu)輸送泵(beng)(beng)既要(yao)有較大輸送量,又能有一定(ding)的出(chu)口(kou)壓力(li)和與(yu)之相(xiang)(xiang)匹配的經濟功(gong)(gong)率,在(zai)混凝土(tu)(tu)輸送泵(beng)(beng)的設計中,大都(dou)采(cai)用了恒功(gong)(gong)率柱塞泵(beng)(beng);即(ji)恒功(gong)(gong)率值選定(ding)后,當(dang)出(chu)口(kou)壓力(li)升高時(shi),油泵(beng)(beng)輸出(chu)排量會自動降低,達(da)到與(yu)功(gong)(gong)率設計相(xiang)(xiang)對應的值;如果既要(yao)達(da)到出(chu)口(kou)壓力(li)高,又想得到輸送量大的目的。惟(wei)一的途徑(jing)就是增加電機(ji)功(gong)(gong)率。
因此,在(zai)國家(jia)新標準中(zhong),引(yin)用了混凝(ning)土輸送泵(beng)的(de)(de)能(neng)(neng)(neng)力(li)(li)指數概念(nian)(以MPa·m3/h為度(du)量(liang)單位(wei));即(ji)混凝(ning)土輸送泵(beng)的(de)(de)實(shi)際出(chu)口壓力(li)(li)與每小時實(shi)際輸送量(liang)之乘積,該值(zhi)越(yue)大(da)(da)(da),其能(neng)(neng)(neng)力(li)(li)指數也越(yue)大(da)(da)(da),電(dian)(dian)機的(de)(de)功(gong)率也將(jiang)越(yue)大(da)(da)(da),由此實(shi)現大(da)(da)(da)排量(liang)、高揚程的(de)(de)目的(de)(de)。科(ke)尼(ni)樂公(gong)司在(zai)設計時,還采(cai)用了高低(di)壓切換的(de)(de)功(gong)能(neng)(neng)(neng)設計,以滿(man)足(zu)不同的(de)(de)施工要求(qiu),在(zai)經(jing)濟狀態(tai)下,又能(neng)(neng)(neng)產生較大(da)(da)(da)的(de)(de)輸送量(liang),或者以相(xiang)同的(de)(de)電(dian)(dian)機功(gong)率,產生較高的(de)(de)出(chu)口壓力(li)(li)。
