選擇多大電(dian)機(ji)混凝(ning)土泵,首先要(yao)考慮變壓器(qi)容量,其次考慮距離混凝(ning)土泵的遠近和線徑大小,以免壓降過大造(zao)成電(dian)流增(zeng)(zeng)高或跳閘(zha)停機(ji),過大功率造(zao)成成本(ben)增(zeng)(zeng)加(jia)和使用不便(bian)。電(dian)機(ji)過小,同時(shi)也滿(man)足不了(le)工程(cheng)需要(yao)。
混凝(ning)土輸送泵功率、混凝(ning)土輸送泵出口壓力、混凝(ning)土輸送泵輸送量之間(jian)的關系。
一臺(tai)混(hun)凝土(tu)輸(shu)送(song)泵(beng)的(de)(de)電機功率(lv)是決定出口(kou)壓力和輸(shu)送(song)方量(liang)(liang)的(de)(de)前提條(tiao)件,在電機功率(lv)一定的(de)(de)情況下,壓力的(de)(de)升高(gao)必將(jiang)使輸(shu)送(song)量(liang)(liang)降低(di);相(xiang)反(fan),降低(di)出口(kou)壓力,將(jiang)會使輸(shu)送(song)量(liang)(liang)增加。
為了保(bao)證混凝土輸(shu)送(song)泵既要(yao)有(you)較大輸(shu)送(song)量(liang),又(you)能有(you)一定的(de)(de)出(chu)口(kou)壓力和與(yu)之相匹配的(de)(de)經濟功(gong)率,在混凝土輸(shu)送(song)泵的(de)(de)設(she)計中(zhong),大都采用了恒功(gong)率柱(zhu)塞泵;即恒功(gong)率值選定后,當出(chu)口(kou)壓力升高時,油泵輸(shu)出(chu)排量(liang)會(hui)自動(dong)降低,達(da)到與(yu)功(gong)率設(she)計相對應的(de)(de)值;如(ru)果既要(yao)達(da)到出(chu)口(kou)壓力高,又(you)想得到輸(shu)送(song)量(liang)大的(de)(de)目(mu)的(de)(de)。惟一的(de)(de)途徑就是(shi)增加電(dian)機功(gong)率。
因(yin)此,在(zai)國家新標準中,引用了(le)混凝土輸送泵的(de)能力(li)(li)(li)指數概(gai)念(以(yi)(yi)MPa·m3/h為度量單位);即混凝土輸送泵的(de)實(shi)際出口壓(ya)力(li)(li)(li)與(yu)每(mei)小(xiao)時(shi)(shi)實(shi)際輸送量之乘積,該值越大(da)(da),其能力(li)(li)(li)指數也越大(da)(da),電(dian)機的(de)功(gong)率也將越大(da)(da),由此實(shi)現(xian)大(da)(da)排(pai)量、高揚程的(de)目(mu)的(de)。科尼樂(le)公司在(zai)設(she)計(ji)時(shi)(shi),還采用了(le)高低壓(ya)切換的(de)功(gong)能設(she)計(ji),以(yi)(yi)滿(man)足不同的(de)施工要求,在(zai)經濟狀態下,又能產生較大(da)(da)的(de)輸送量,或者以(yi)(yi)相同的(de)電(dian)機功(gong)率,產生較高的(de)出口壓(ya)力(li)(li)(li)。
