37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(目前國內(nei)標準混凝(ning)土泵(beng),37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)以下(xia)為細石(shi)砂漿泵(beng))、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)油(you))、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)油(you))、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)油(you))等等。
選擇多大電機混凝(ning)土泵(beng),首先要考(kao)(kao)慮變壓(ya)器(qi)容量,其次考(kao)(kao)慮距離混凝(ning)土泵(beng)的(de)遠(yuan)近和線徑大小,以免壓(ya)降(jiang)過大造(zao)成(cheng)電流(liu)增(zeng)高或跳閘停機,過大功率造(zao)成(cheng)成(cheng)本增(zeng)加和使用不(bu)便。電機過小,同時也滿足不(bu)了工程(cheng)需要。
混凝土輸(shu)送泵(beng)功(gong)率、混凝土輸(shu)送泵(beng)出口壓(ya)力、混凝土輸(shu)送泵(beng)輸(shu)送量之(zhi)間的(de)關系
一(yi)臺混凝土輸送(song)(song)泵(beng)的(de)(de)電(dian)機(ji)功率(lv)是決定出口(kou)壓力和輸送(song)(song)方量(liang)的(de)(de)前提條件,在電(dian)機(ji)功率(lv)一(yi)定的(de)(de)情況下,壓力的(de)(de)升高必將(jiang)(jiang)使(shi)輸送(song)(song)量(liang)降(jiang)低;相(xiang)反,降(jiang)低出口(kou)壓力,將(jiang)(jiang)會使(shi)輸送(song)(song)量(liang)增加。
為了保證混(hun)凝土輸送(song)(song)泵(beng)既要(yao)有(you)較大輸送(song)(song)量(liang),又能有(you)一定的(de)(de)出口(kou)壓(ya)(ya)力和與之(zhi)相(xiang)匹配(pei)的(de)(de)經濟(ji)功(gong)(gong)率,在混(hun)凝土輸送(song)(song)泵(beng)的(de)(de)設計(ji)中,大都采用(yong)了恒功(gong)(gong)率柱(zhu)塞泵(beng);即恒功(gong)(gong)率值(zhi)選定后,當出口(kou)壓(ya)(ya)力升高(gao)時,油泵(beng)輸出排量(liang)會(hui)自(zi)動降低,達(da)到與功(gong)(gong)率設計(ji)相(xiang)對應的(de)(de)值(zhi);如果既要(yao)達(da)到出口(kou)壓(ya)(ya)力高(gao),又想得到輸送(song)(song)量(liang)大的(de)(de)目(mu)的(de)(de)。惟一的(de)(de)途(tu)徑就是增(zeng)加電機功(gong)(gong)率。
因此(ci)(ci),在國家新標準中(zhong),引用(yong)了混凝土輸(shu)送泵的(de)(de)(de)(de)能(neng)力指數概念(以(yi)MPa·m3/h為度量單位);即混凝土輸(shu)送泵的(de)(de)(de)(de)實(shi)際出口(kou)壓(ya)(ya)力與(yu)每小時實(shi)際輸(shu)送量之(zhi)乘積,該值越(yue)(yue)大,其能(neng)力指數也越(yue)(yue)大,電機的(de)(de)(de)(de)功率(lv)(lv)也將越(yue)(yue)大,由(you)此(ci)(ci)實(shi)現大排(pai)量、高揚程的(de)(de)(de)(de)目的(de)(de)(de)(de)。科(ke)尼樂公司在設(she)計時,還采用(yong)了高低壓(ya)(ya)切(qie)換的(de)(de)(de)(de)功能(neng)設(she)計,以(yi)滿足不同的(de)(de)(de)(de)施工要求(qiu),在經濟狀態下,又能(neng)產生較(jiao)大的(de)(de)(de)(de)輸(shu)送量,或者以(yi)相同的(de)(de)(de)(de)電機功率(lv)(lv),產生較(jiao)高的(de)(de)(de)(de)出口(kou)壓(ya)(ya)力。
