37千(qian)瓦(wa)(目前國內標準(zhun)混凝(ning)土泵,37千(qian)瓦(wa)以下為(wei)細石砂漿泵)、45千(qian)瓦(wa)、55千(qian)瓦(wa)、75千(qian)瓦(wa)、90千(qian)瓦(wa)、110千(qian)瓦(wa)、130千(qian)瓦(wa)(柴(chai)油(you))、132千(qian)瓦(wa)、162千(qian)瓦(wa)(柴(chai)油(you))、174千(qian)瓦(wa)(柴(chai)油(you))等等。
選擇(ze)多大(da)電(dian)機混凝(ning)土(tu)泵,首先要考慮變壓(ya)(ya)器容量,其(qi)次(ci)考慮距離混凝(ning)土(tu)泵的遠近和線徑(jing)大(da)小(xiao),以免(mian)壓(ya)(ya)降過大(da)造成(cheng)電(dian)流(liu)增高或跳閘停(ting)機,過大(da)功率造成(cheng)成(cheng)本增加和使用不(bu)(bu)便。電(dian)機過小(xiao),同(tong)時也滿足不(bu)(bu)了工程需要。
混(hun)凝土(tu)(tu)輸(shu)送(song)(song)泵(beng)(beng)功率、混(hun)凝土(tu)(tu)輸(shu)送(song)(song)泵(beng)(beng)出(chu)口壓力、混(hun)凝土(tu)(tu)輸(shu)送(song)(song)泵(beng)(beng)輸(shu)送(song)(song)量之(zhi)間的關系(xi)
一臺混凝土輸送(song)(song)泵的(de)電機功率是決(jue)定出(chu)口(kou)壓(ya)力和輸送(song)(song)方量(liang)(liang)的(de)前提條件,在(zai)電機功率一定的(de)情(qing)況下,壓(ya)力的(de)升高必(bi)將使(shi)輸送(song)(song)量(liang)(liang)降低(di);相反,降低(di)出(chu)口(kou)壓(ya)力,將會(hui)使(shi)輸送(song)(song)量(liang)(liang)增(zeng)加(jia)。
為了保證混凝(ning)(ning)土輸(shu)送(song)(song)泵(beng)既要有較(jiao)大(da)輸(shu)送(song)(song)量,又能有一(yi)定的出口壓(ya)力和與之相匹配的經(jing)濟(ji)功(gong)率,在混凝(ning)(ning)土輸(shu)送(song)(song)泵(beng)的設(she)計中,大(da)都采(cai)用了恒功(gong)率柱(zhu)塞泵(beng);即恒功(gong)率值選定后,當出口壓(ya)力升高(gao)時(shi),油泵(beng)輸(shu)出排量會自動(dong)降(jiang)低,達到(dao)與功(gong)率設(she)計相對(dui)應的值;如果既要達到(dao)出口壓(ya)力高(gao),又想得到(dao)輸(shu)送(song)(song)量大(da)的目的。惟一(yi)的途徑就是增加電機功(gong)率。
因(yin)此,在(zai)國(guo)家新標準中,引用(yong)了混凝(ning)土輸(shu)送(song)(song)泵的(de)(de)能(neng)(neng)力指數概(gai)念(nian)(以(yi)MPa·m3/h為度量單位);即混凝(ning)土輸(shu)送(song)(song)泵的(de)(de)實(shi)際出(chu)口(kou)壓力與每(mei)小(xiao)時(shi)實(shi)際輸(shu)送(song)(song)量之乘積,該值越大(da),其能(neng)(neng)力指數也越大(da),電機的(de)(de)功率也將越大(da),由此實(shi)現大(da)排(pai)量、高(gao)(gao)揚程的(de)(de)目的(de)(de)。科尼樂公司在(zai)設(she)(she)計(ji)時(shi),還(huan)采用(yong)了高(gao)(gao)低壓切換的(de)(de)功能(neng)(neng)設(she)(she)計(ji),以(yi)滿(man)足(zu)不同(tong)的(de)(de)施(shi)工要求(qiu),在(zai)經濟狀態下,又(you)能(neng)(neng)產生較(jiao)大(da)的(de)(de)輸(shu)送(song)(song)量,或者以(yi)相同(tong)的(de)(de)電機功率,產生較(jiao)高(gao)(gao)的(de)(de)出(chu)口(kou)壓力。
