選擇多大(da)(da)電(dian)機(ji)混(hun)凝(ning)土(tu)泵,首(shou)先要考(kao)慮變(bian)壓器容量(liang),其次考(kao)慮距離混(hun)凝(ning)土(tu)泵的遠(yuan)近和(he)線徑大(da)(da)小,以免壓降過(guo)大(da)(da)造(zao)(zao)成(cheng)電(dian)流增高(gao)或跳閘停機(ji),過(guo)大(da)(da)功(gong)率造(zao)(zao)成(cheng)成(cheng)本(ben)增加和(he)使用不(bu)便。電(dian)機(ji)過(guo)小,同時也滿(man)足不(bu)了工(gong)程需要。
混凝(ning)土(tu)輸(shu)(shu)送(song)泵(beng)功率(lv)、混凝(ning)土(tu)輸(shu)(shu)送(song)泵(beng)出口壓力、混凝(ning)土(tu)輸(shu)(shu)送(song)泵(beng)輸(shu)(shu)送(song)量之間的關(guan)系(xi)
一(yi)臺混(hun)凝土(tu)輸(shu)(shu)送泵的(de)電(dian)機功率(lv)是決定出(chu)口(kou)壓(ya)力(li)和輸(shu)(shu)送方量的(de)前(qian)提條件,在電(dian)機功率(lv)一(yi)定的(de)情況下,壓(ya)力(li)的(de)升高必將(jiang)使(shi)輸(shu)(shu)送量降(jiang)低;相反,降(jiang)低出(chu)口(kou)壓(ya)力(li),將(jiang)會(hui)使(shi)輸(shu)(shu)送量增(zeng)加。
為了保證混(hun)凝土輸(shu)送泵(beng)既(ji)要有較大輸(shu)送量(liang),又能(neng)有一(yi)定的(de)出口(kou)壓力和(he)與(yu)之相匹(pi)配的(de)經濟(ji)功(gong)率,在混(hun)凝土輸(shu)送泵(beng)的(de)設計中,大都采用了恒功(gong)率柱塞泵(beng);即恒功(gong)率值(zhi)選(xuan)定后,當出口(kou)壓力升高(gao)時,油(you)泵(beng)輸(shu)出排量(liang)會自動降低,達到(dao)與(yu)功(gong)率設計相對應(ying)的(de)值(zhi);如果既(ji)要達到(dao)出口(kou)壓力高(gao),又想(xiang)得到(dao)輸(shu)送量(liang)大的(de)目的(de)。惟(wei)一(yi)的(de)途(tu)徑就是(shi)增加電(dian)機(ji)功(gong)率。
因(yin)此,在(zai)國(guo)家新標準(zhun)中(zhong),引用了混(hun)凝(ning)土(tu)輸(shu)送(song)泵(beng)的(de)(de)(de)能(neng)(neng)力指數(shu)概念(以(yi)(yi)MPa·m3/h為度量(liang)單位(wei));即(ji)混(hun)凝(ning)土(tu)輸(shu)送(song)泵(beng)的(de)(de)(de)實際出口壓力與每小時實際輸(shu)送(song)量(liang)之乘積,該值越大(da),其能(neng)(neng)力指數(shu)也越大(da),電機(ji)的(de)(de)(de)功(gong)率也將越大(da),由(you)此實現大(da)排量(liang)、高(gao)揚程的(de)(de)(de)目的(de)(de)(de)。科尼(ni)樂公司(si)在(zai)設計時,還采用了高(gao)低壓切(qie)換的(de)(de)(de)功(gong)能(neng)(neng)設計,以(yi)(yi)滿足不同的(de)(de)(de)施(shi)工要求,在(zai)經濟(ji)狀態(tai)下(xia),又能(neng)(neng)產(chan)生(sheng)較(jiao)大(da)的(de)(de)(de)輸(shu)送(song)量(liang),或者以(yi)(yi)相同的(de)(de)(de)電機(ji)功(gong)率,產(chan)生(sheng)較(jiao)高(gao)的(de)(de)(de)出口壓力。
