一、電動混凝土輸送泵功率是多少
混(hun)凝土輸送泵有柴(chai)油泵和電(dian)動(dong)(dong)泵兩(liang)種(zhong),其中(zhong)電(dian)動(dong)(dong)混(hun)凝土輸送泵的主要(yao)衡量指標(biao)就(jiu)是電(dian)機功(gong)(gong)率(lv)(lv)(lv),即每小時(shi)電(dian)動(dong)(dong)混(hun)凝土輸送泵的電(dian)機正常(chang)工作時(shi)的額定功(gong)(gong)率(lv)(lv)(lv),功(gong)(gong)率(lv)(lv)(lv)過(guo)大可能(neng)造成成本過(guo)高(gao)或使用不便,功(gong)(gong)率(lv)(lv)(lv)過(guo)小則滿(man)足不了工程需(xu)求,因此選擇合適的功(gong)(gong)率(lv)(lv)(lv)非常(chang)重(zhong)要(yao)。
為了保證(zheng)混(hun)(hun)凝(ning)(ning)土(tu)輸(shu)送(song)泵(beng)既要(yao)有較大輸(shu)送(song)量,又能有一定的出(chu)口壓力和與之相(xiang)匹配的經濟功率,在混(hun)(hun)凝(ning)(ning)土(tu)輸(shu)送(song)泵(beng)的設計(ji)中,大都(dou)采用了恒功率柱(zhu)塞泵(beng),電動混(hun)(hun)凝(ning)(ning)土(tu)輸(shu)送(song)泵(beng)的功率一般以千(qian)(qian)瓦為單位,常見的有30千(qian)(qian)瓦、45千(qian)(qian)瓦、55千(qian)(qian)瓦、60千(qian)(qian)瓦、75千(qian)(qian)瓦、90千(qian)(qian)瓦、110千(qian)(qian)瓦、132千(qian)(qian)瓦等多種(zhong)。那么(me)(me)混(hun)(hun)凝(ning)(ning)土(tu)輸(shu)送(song)泵(beng)功率怎么(me)(me)選呢(ni)?
二、如何選擇合適的混凝土輸送泵功率
國(guo)家標準(zhun)中(zhong)有混凝(ning)(ning)土(tu)(tu)(tu)輸(shu)(shu)送(song)泵的(de)(de)(de)能力(li)(li)(li)指數的(de)(de)(de)概念(nian):混凝(ning)(ning)土(tu)(tu)(tu)輸(shu)(shu)送(song)泵的(de)(de)(de)能力(li)(li)(li)指數=混凝(ning)(ning)土(tu)(tu)(tu)輸(shu)(shu)送(song)泵的(de)(de)(de)實際出口(kou)(kou)壓(ya)(ya)力(li)(li)(li)×每小時(shi)實際輸(shu)(shu)送(song)量,該值越(yue)大(da)(da),電機的(de)(de)(de)功(gong)(gong)率(lv)也將越(yue)大(da)(da)。一(yi)(yi)臺(tai)混凝(ning)(ning)土(tu)(tu)(tu)輸(shu)(shu)送(song)泵的(de)(de)(de)電機功(gong)(gong)率(lv)是(shi)決定(ding)出口(kou)(kou)壓(ya)(ya)力(li)(li)(li)和輸(shu)(shu)送(song)方(fang)量的(de)(de)(de)前提(ti)條件,在電機功(gong)(gong)率(lv)一(yi)(yi)定(ding)的(de)(de)(de)情況下,壓(ya)(ya)力(li)(li)(li)的(de)(de)(de)升高必將使輸(shu)(shu)送(song)量降低(di);相反,降低(di)出口(kou)(kou)壓(ya)(ya)力(li)(li)(li),將會使輸(shu)(shu)送(song)量增加(jia)。選擇混凝(ning)(ning)土(tu)(tu)(tu)輸(shu)(shu)送(song)泵功(gong)(gong)率(lv)要考慮的(de)(de)(de)因素(su)主(zhu)要有:
1、變壓器容(rong)量。
2、距離混凝土泵的遠近和線徑(jing)大小(xiao)。
在設計混凝土輸送泵時(shi),也有(you)的(de)(de)生產廠(chang)家(jia)采用(yong)高低壓切換的(de)(de)功能設(she)計,不光能滿足不同的(de)(de)施(shi)工要求,還能以相同的(de)(de)電機功率,產生較(jiao)高的(de)(de)出口壓力。
