37千(qian)(qian)瓦(wa)(wa)(wa)(目前國內標準混凝土泵,37千(qian)(qian)瓦(wa)(wa)(wa)以(yi)下為細石砂漿泵)、45千(qian)(qian)瓦(wa)(wa)(wa)、55千(qian)(qian)瓦(wa)(wa)(wa)、75千(qian)(qian)瓦(wa)(wa)(wa)、90千(qian)(qian)瓦(wa)(wa)(wa)、110千(qian)(qian)瓦(wa)(wa)(wa)、130千(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油)、132千(qian)(qian)瓦(wa)(wa)(wa)、162千(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油)、174千(qian)(qian)瓦(wa)(wa)(wa)(柴(chai)油)等等。
選擇(ze)多(duo)大(da)電機(ji)混凝土泵,首先要(yao)考慮變壓器(qi)容量,其次考慮距離混凝土泵的遠近和(he)線徑大(da)小(xiao),以免壓降過(guo)(guo)大(da)造(zao)成電流增(zeng)高或跳閘(zha)停機(ji),過(guo)(guo)大(da)功率造(zao)成成本增(zeng)加和(he)使用不便(bian)。電機(ji)過(guo)(guo)小(xiao),同時(shi)也滿足(zu)不了工程需要(yao)。
混(hun)凝土(tu)輸(shu)送(song)泵功率、混(hun)凝土(tu)輸(shu)送(song)泵出口(kou)壓(ya)力(li)、混(hun)凝土(tu)輸(shu)送(song)泵輸(shu)送(song)量(liang)之(zhi)間的(de)關系
一臺(tai)混凝土輸(shu)送(song)泵的電機(ji)功率是決(jue)定(ding)出(chu)(chu)口(kou)壓(ya)力和輸(shu)送(song)方量(liang)的前提條件,在(zai)電機(ji)功率一定(ding)的情(qing)況下,壓(ya)力的升高必將(jiang)使輸(shu)送(song)量(liang)降低(di)(di);相反(fan),降低(di)(di)出(chu)(chu)口(kou)壓(ya)力,將(jiang)會使輸(shu)送(song)量(liang)增加。
為了保證混(hun)凝土輸(shu)送(song)泵(beng)(beng)既要有(you)較大輸(shu)送(song)量,又能(neng)有(you)一定的(de)(de)出口(kou)壓(ya)力和與之相匹(pi)配的(de)(de)經濟功(gong)(gong)(gong)率(lv)(lv),在(zai)混(hun)凝土輸(shu)送(song)泵(beng)(beng)的(de)(de)設(she)(she)計中,大都(dou)采用了恒(heng)功(gong)(gong)(gong)率(lv)(lv)柱塞泵(beng)(beng);即恒(heng)功(gong)(gong)(gong)率(lv)(lv)值選定后,當出口(kou)壓(ya)力升(sheng)高時,油泵(beng)(beng)輸(shu)出排量會自動降低,達到(dao)(dao)與功(gong)(gong)(gong)率(lv)(lv)設(she)(she)計相對應的(de)(de)值;如果既要達到(dao)(dao)出口(kou)壓(ya)力高,又想得到(dao)(dao)輸(shu)送(song)量大的(de)(de)目的(de)(de)。惟一的(de)(de)途(tu)徑(jing)就是增加電機功(gong)(gong)(gong)率(lv)(lv)。
因此,在(zai)國家新標準中(zhong),引用了(le)混凝土(tu)輸(shu)(shu)送(song)(song)泵的(de)(de)能(neng)力(li)(li)指數概念(以(yi)(yi)(yi)MPa·m3/h為度(du)量(liang)(liang)單位);即(ji)混凝土(tu)輸(shu)(shu)送(song)(song)泵的(de)(de)實(shi)際出口壓(ya)力(li)(li)與(yu)每小(xiao)時(shi)實(shi)際輸(shu)(shu)送(song)(song)量(liang)(liang)之(zhi)乘積,該(gai)值越大(da),其(qi)能(neng)力(li)(li)指數也越大(da),電機的(de)(de)功(gong)率也將(jiang)越大(da),由此實(shi)現大(da)排量(liang)(liang)、高(gao)揚程(cheng)的(de)(de)目的(de)(de)。科尼樂公司在(zai)設(she)計(ji)時(shi),還采(cai)用了(le)高(gao)低壓(ya)切換(huan)的(de)(de)功(gong)能(neng)設(she)計(ji),以(yi)(yi)(yi)滿足不同的(de)(de)施工(gong)要求,在(zai)經濟狀態下,又能(neng)產(chan)生較大(da)的(de)(de)輸(shu)(shu)送(song)(song)量(liang)(liang),或者以(yi)(yi)(yi)相同的(de)(de)電機功(gong)率,產(chan)生較高(gao)的(de)(de)出口壓(ya)力(li)(li)。
