選擇多大電機混(hun)凝(ning)土(tu)泵(beng),首先要考(kao)慮(lv)變壓(ya)器(qi)容量,其(qi)次考(kao)慮(lv)距離混(hun)凝(ning)土(tu)泵(beng)的遠(yuan)近(jin)和線(xian)徑大小,以免壓(ya)降過(guo)大造成(cheng)電流(liu)增(zeng)高或(huo)跳閘停(ting)機,過(guo)大功率造成(cheng)成(cheng)本增(zeng)加和使用不便。電機過(guo)小,同時也(ye)滿足不了工(gong)程需要。
混凝(ning)土(tu)(tu)輸(shu)送泵(beng)(beng)功率、混凝(ning)土(tu)(tu)輸(shu)送泵(beng)(beng)出(chu)口壓力、混凝(ning)土(tu)(tu)輸(shu)送泵(beng)(beng)輸(shu)送量(liang)之間的關系。
一(yi)臺混凝土輸(shu)送(song)(song)(song)泵的(de)(de)電機功率(lv)是(shi)決定出口壓(ya)力和輸(shu)送(song)(song)(song)方量(liang)的(de)(de)前提條件(jian),在電機功率(lv)一(yi)定的(de)(de)情況下,壓(ya)力的(de)(de)升高必將使(shi)輸(shu)送(song)(song)(song)量(liang)降低(di);相反,降低(di)出口壓(ya)力,將會使(shi)輸(shu)送(song)(song)(song)量(liang)增加。
為了保(bao)證混(hun)凝(ning)土輸(shu)送泵(beng)既(ji)要有較大輸(shu)送量(liang),又能有一定(ding)的出(chu)口(kou)壓力和與之相匹配的經濟(ji)功(gong)率,在(zai)混(hun)凝(ning)土輸(shu)送泵(beng)的設計(ji)中,大都采用了恒(heng)(heng)功(gong)率柱(zhu)塞泵(beng);即恒(heng)(heng)功(gong)率值(zhi)選(xuan)定(ding)后,當出(chu)口(kou)壓力升高時,油泵(beng)輸(shu)出(chu)排量(liang)會自(zi)動降低,達到與功(gong)率設計(ji)相對應的值(zhi);如(ru)果既(ji)要達到出(chu)口(kou)壓力高,又想得到輸(shu)送量(liang)大的目(mu)的。惟一的途徑就是增加電機(ji)功(gong)率。
因(yin)此,在國家新(xin)標準中(zhong),引用了(le)混凝土(tu)輸送(song)泵的(de)(de)(de)(de)(de)能力指數概念(以(yi)(yi)(yi)MPa·m3/h為度量單位);即混凝土(tu)輸送(song)泵的(de)(de)(de)(de)(de)實際出口(kou)壓力與每小時實際輸送(song)量之乘積,該值越大(da)(da),其能力指數也(ye)越大(da)(da),電機的(de)(de)(de)(de)(de)功率也(ye)將越大(da)(da),由此實現(xian)大(da)(da)排量、高揚程的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)。科(ke)尼樂公司在設(she)計時,還(huan)采(cai)用了(le)高低壓切換的(de)(de)(de)(de)(de)功能設(she)計,以(yi)(yi)(yi)滿足不同(tong)的(de)(de)(de)(de)(de)施工要求,在經濟狀態下(xia),又能產生較大(da)(da)的(de)(de)(de)(de)(de)輸送(song)量,或者以(yi)(yi)(yi)相(xiang)同(tong)的(de)(de)(de)(de)(de)電機功率,產生較高的(de)(de)(de)(de)(de)出口(kou)壓力。
