具體參數
拖泵分類(lei)選型
37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(目(mu)前國內標(biao)準混凝土泵,37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)以下為細石砂(sha)漿泵)、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油)、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油)、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油)等等。
選擇多大電(dian)機混凝(ning)(ning)土(tu)泵,首先(xian)要(yao)考慮變壓(ya)器容(rong)量,其(qi)次(ci)考慮距離混凝(ning)(ning)土(tu)泵的遠近和線徑大小(xiao),以免壓(ya)降過(guo)大造成(cheng)電(dian)流增高(gao)或跳閘停機,過(guo)大功率造成(cheng)成(cheng)本增加和使用不(bu)便。電(dian)機過(guo)小(xiao),同時也滿足不(bu)了工程需要(yao)。
混(hun)凝土(tu)(tu)輸送泵功率、混(hun)凝土(tu)(tu)輸送泵出口壓力、混(hun)凝土(tu)(tu)輸送泵輸送量之間的關系
一臺混(hun)凝土輸(shu)(shu)送(song)泵的(de)電(dian)機(ji)功率(lv)是決(jue)定(ding)出口壓力和(he)輸(shu)(shu)送(song)方量的(de)前(qian)提條(tiao)件,在電(dian)機(ji)功率(lv)一定(ding)的(de)情況下,壓力的(de)升高必將(jiang)使輸(shu)(shu)送(song)量降低(di);相反,降低(di)出口壓力,將(jiang)會使輸(shu)(shu)送(song)量增加(jia)。
為了保證混(hun)凝土輸(shu)送(song)泵(beng)既(ji)(ji)要有較大輸(shu)送(song)量,又(you)能有一(yi)定(ding)的(de)(de)出口(kou)壓力和與(yu)之相匹配的(de)(de)經濟功(gong)(gong)率(lv)(lv),在混(hun)凝土輸(shu)送(song)泵(beng)的(de)(de)設計中,大都采用了恒功(gong)(gong)率(lv)(lv)柱塞泵(beng);即(ji)恒功(gong)(gong)率(lv)(lv)值選定(ding)后,當出口(kou)壓力升高時,油泵(beng)輸(shu)出排量會自動降低,達到(dao)與(yu)功(gong)(gong)率(lv)(lv)設計相對應的(de)(de)值;如(ru)果既(ji)(ji)要達到(dao)出口(kou)壓力高,又(you)想得到(dao)輸(shu)送(song)量大的(de)(de)目(mu)的(de)(de)。惟(wei)一(yi)的(de)(de)途(tu)徑就是(shi)增加電機功(gong)(gong)率(lv)(lv)。
因此,在(zai)(zai)國家新標(biao)準中,引用了(le)混(hun)凝(ning)土(tu)輸送(song)泵(beng)的(de)(de)(de)能(neng)(neng)力(li)指(zhi)數概念(nian)(以(yi)MPa·m3/h為度(du)量單位);即混(hun)凝(ning)土(tu)輸送(song)泵(beng)的(de)(de)(de)實際出(chu)口(kou)(kou)壓力(li)與每(mei)小時(shi)實際輸送(song)量之乘積,該值越大,其能(neng)(neng)力(li)指(zhi)數也越大,電(dian)機的(de)(de)(de)功率也將越大,由此實現大排量、高揚(yang)程的(de)(de)(de)目(mu)的(de)(de)(de)。科尼(ni)樂公司在(zai)(zai)設(she)計時(shi),還采(cai)用了(le)高低壓切(qie)換(huan)的(de)(de)(de)功能(neng)(neng)設(she)計,以(yi)滿足不同的(de)(de)(de)施工(gong)要(yao)求,在(zai)(zai)經(jing)濟狀態下,又(you)能(neng)(neng)產生較大的(de)(de)(de)輸送(song)量,或者以(yi)相同的(de)(de)(de)電(dian)機功率,產生較高的(de)(de)(de)出(chu)口(kou)(kou)壓力(li)。
