37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(目(mu)前國內標(biao)準混凝土泵,37千(qian)(qian)(qian)(qian)瓦(wa)(wa)以(yi)下為細石(shi)砂漿泵)、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油)、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油)、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴油)等(deng)等(deng)。
選(xuan)擇(ze)多大(da)電機(ji)混(hun)凝土(tu)泵,首先要考慮變(bian)壓(ya)器容量,其次考慮距離混(hun)凝土(tu)泵的遠近和線徑大(da)小(xiao),以免壓(ya)降(jiang)過大(da)造成(cheng)電流增高或跳閘(zha)停機(ji),過大(da)功(gong)率造成(cheng)成(cheng)本(ben)增加和使(shi)用(yong)不(bu)便。電機(ji)過小(xiao),同時也滿足不(bu)了工程需要。
混凝土輸(shu)送(song)(song)泵(beng)功率、混凝土輸(shu)送(song)(song)泵(beng)出口壓力、混凝土輸(shu)送(song)(song)泵(beng)輸(shu)送(song)(song)量之間(jian)的關系(xi)。
一(yi)臺混凝(ning)土輸送泵的電(dian)機功(gong)率(lv)是(shi)決定(ding)出口(kou)壓力和輸送方量的前提條件(jian),在(zai)電(dian)機功(gong)率(lv)一(yi)定(ding)的情(qing)況下,壓力的升(sheng)高必將(jiang)使輸送量降(jiang)低;相反,降(jiang)低出口(kou)壓力,將(jiang)會使輸送量增加。
為了保(bao)證混凝土(tu)輸(shu)送(song)泵(beng)既(ji)要有(you)(you)較大(da)輸(shu)送(song)量(liang),又能有(you)(you)一(yi)定(ding)的(de)(de)出口壓(ya)力和與之相匹(pi)配的(de)(de)經濟功(gong)(gong)率(lv),在(zai)混凝土(tu)輸(shu)送(song)泵(beng)的(de)(de)設計中(zhong),大(da)都(dou)采(cai)用了恒功(gong)(gong)率(lv)柱塞泵(beng);即恒功(gong)(gong)率(lv)值選定(ding)后,當出口壓(ya)力升高時,油泵(beng)輸(shu)出排量(liang)會自動降(jiang)低,達到(dao)與功(gong)(gong)率(lv)設計相對應的(de)(de)值;如果既(ji)要達到(dao)出口壓(ya)力高,又想得到(dao)輸(shu)送(song)量(liang)大(da)的(de)(de)目的(de)(de)。惟(wei)一(yi)的(de)(de)途徑就是(shi)增(zeng)加電機功(gong)(gong)率(lv)。
因此(ci),在(zai)(zai)國家新標準(zhun)中,引(yin)用了混凝(ning)土輸(shu)送(song)(song)泵的(de)(de)(de)能(neng)(neng)力(li)指數(shu)概念(以MPa·m3/h為度量(liang)單位);即混凝(ning)土輸(shu)送(song)(song)泵的(de)(de)(de)實際出口壓力(li)與每(mei)小時實際輸(shu)送(song)(song)量(liang)之乘積,該(gai)值越(yue)大(da),其能(neng)(neng)力(li)指數(shu)也越(yue)大(da),電機(ji)的(de)(de)(de)功率也將越(yue)大(da),由(you)此(ci)實現(xian)大(da)排量(liang)、高揚程的(de)(de)(de)目的(de)(de)(de)。科尼(ni)樂公司在(zai)(zai)設(she)計(ji)時,還采(cai)用了高低壓切換(huan)的(de)(de)(de)功能(neng)(neng)設(she)計(ji),以滿足(zu)不同的(de)(de)(de)施工要求,在(zai)(zai)經濟狀態(tai)下,又能(neng)(neng)產生較大(da)的(de)(de)(de)輸(shu)送(song)(song)量(liang),或者以相(xiang)同的(de)(de)(de)電機(ji)功率,產生較高的(de)(de)(de)出口壓力(li)。
