拖泵(beng)分(fen)類選型
37千(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)瓦(wa)(wa)以下為細石砂漿泵(beng)(beng))、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)(柴油(you))、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油(you))等(deng)等(deng)。
選擇(ze)多大(da)(da)(da)電(dian)(dian)機(ji)混凝(ning)土泵(beng),首先要(yao)考慮(lv)變(bian)壓器容量,其次考慮(lv)距離混凝(ning)土泵(beng)的遠(yuan)近和(he)線徑大(da)(da)(da)小(xiao),以免壓降過大(da)(da)(da)造(zao)成(cheng)(cheng)電(dian)(dian)流(liu)增(zeng)高或(huo)跳閘停機(ji),過大(da)(da)(da)功率造(zao)成(cheng)(cheng)成(cheng)(cheng)本增(zeng)加和(he)使(shi)用不(bu)便。電(dian)(dian)機(ji)過小(xiao),同時也滿足不(bu)了工程需要(yao)。
混凝土(tu)輸送泵(beng)功率、混凝土(tu)輸送泵(beng)出口壓力、混凝土(tu)輸送泵(beng)輸送量(liang)之間的關系
一臺(tai)混(hun)凝土輸送(song)(song)(song)泵的(de)(de)電機功(gong)率是決(jue)定(ding)出口(kou)壓(ya)力和輸送(song)(song)(song)方量的(de)(de)前提條件,在電機功(gong)率一定(ding)的(de)(de)情況下(xia),壓(ya)力的(de)(de)升高(gao)必將使(shi)輸送(song)(song)(song)量降低;相反,降低出口(kou)壓(ya)力,將會使(shi)輸送(song)(song)(song)量增加。
為了(le)(le)保證混(hun)凝土輸(shu)送(song)泵既(ji)要(yao)有較大(da)輸(shu)送(song)量(liang),又能有一定的(de)出口(kou)壓(ya)力和與之(zhi)相(xiang)匹配(pei)的(de)經濟功(gong)(gong)率(lv),在混(hun)凝土輸(shu)送(song)泵的(de)設計中,大(da)都采用(yong)了(le)(le)恒(heng)功(gong)(gong)率(lv)柱塞(sai)泵;即恒(heng)功(gong)(gong)率(lv)值選(xuan)定后,當出口(kou)壓(ya)力升高時(shi),油泵輸(shu)出排(pai)量(liang)會自(zi)動降低(di),達到與功(gong)(gong)率(lv)設計相(xiang)對應的(de)值;如果(guo)既(ji)要(yao)達到出口(kou)壓(ya)力高,又想得到輸(shu)送(song)量(liang)大(da)的(de)目(mu)的(de)。惟(wei)一的(de)途(tu)徑(jing)就是(shi)增加電機(ji)功(gong)(gong)率(lv)。
因(yin)此,在(zai)(zai)(zai)國家新標準中,引用了混凝(ning)(ning)土(tu)輸送泵的(de)(de)能力(li)指數概念(nian)(以(yi)MPa·m3/h為度量(liang)單位);即混凝(ning)(ning)土(tu)輸送泵的(de)(de)實際出(chu)口(kou)壓力(li)與(yu)每小時實際輸送量(liang)之乘積(ji),該值(zhi)越(yue)(yue)(yue)大(da),其能力(li)指數也越(yue)(yue)(yue)大(da),電機的(de)(de)功(gong)(gong)率也將越(yue)(yue)(yue)大(da),由此實現大(da)排量(liang)、高(gao)揚(yang)程的(de)(de)目的(de)(de)。科尼(ni)樂公(gong)司在(zai)(zai)(zai)設(she)(she)計(ji)(ji)時,還采用了高(gao)低壓切換(huan)的(de)(de)功(gong)(gong)能設(she)(she)計(ji)(ji),以(yi)滿足不同的(de)(de)施工要求,在(zai)(zai)(zai)經濟狀(zhuang)態下,又能產生較大(da)的(de)(de)輸送量(liang),或者以(yi)相(xiang)同的(de)(de)電機功(gong)(gong)率,產生較高(gao)的(de)(de)出(chu)口(kou)壓力(li)。
