37千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(目前國內標準混凝土泵,37千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)以下為細石(shi)砂漿泵)、45千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、55千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、75千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、90千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、110千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、130千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)油(you))、132千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、162千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)油(you))、174千(qian)(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)油(you))等(deng)等(deng)。
選(xuan)擇多大(da)(da)電機(ji)混凝土泵(beng),首先要(yao)考慮變壓器(qi)容量,其次考慮距離混凝土泵(beng)的遠近和線徑大(da)(da)小,以免壓降過大(da)(da)造成(cheng)電流增高(gao)或跳閘(zha)停(ting)機(ji),過大(da)(da)功率造成(cheng)成(cheng)本(ben)增加和使用不(bu)便。電機(ji)過小,同時(shi)也滿足不(bu)了工程需要(yao)。
混(hun)(hun)凝(ning)土(tu)輸送泵(beng)功率(lv)、混(hun)(hun)凝(ning)土(tu)輸送泵(beng)出(chu)口壓力、混(hun)(hun)凝(ning)土(tu)輸送泵(beng)輸送量之間的(de)關(guan)系。
一(yi)臺混凝土(tu)輸(shu)送(song)(song)(song)泵的電機(ji)功(gong)率是決定出口壓力(li)(li)(li)和輸(shu)送(song)(song)(song)方量(liang)的前提條(tiao)件(jian),在電機(ji)功(gong)率一(yi)定的情(qing)況下(xia),壓力(li)(li)(li)的升高必將(jiang)使輸(shu)送(song)(song)(song)量(liang)降低;相(xiang)反,降低出口壓力(li)(li)(li),將(jiang)會使輸(shu)送(song)(song)(song)量(liang)增加。
為(wei)了(le)保證混凝土(tu)輸(shu)(shu)(shu)(shu)送泵既要有較大(da)輸(shu)(shu)(shu)(shu)送量,又能有一定(ding)(ding)的(de)出(chu)口(kou)壓力(li)和(he)與(yu)之相匹(pi)配的(de)經濟功(gong)率,在混凝土(tu)輸(shu)(shu)(shu)(shu)送泵的(de)設計中,大(da)都采用了(le)恒功(gong)率柱塞泵;即恒功(gong)率值選定(ding)(ding)后,當出(chu)口(kou)壓力(li)升高(gao)時(shi),油泵輸(shu)(shu)(shu)(shu)出(chu)排(pai)量會自動降低,達到與(yu)功(gong)率設計相對應的(de)值;如果既要達到出(chu)口(kou)壓力(li)高(gao),又想(xiang)得到輸(shu)(shu)(shu)(shu)送量大(da)的(de)目的(de)。惟(wei)一的(de)途徑就是(shi)增加電機功(gong)率。
因(yin)此,在國家新標準(zhun)中(zhong),引用了(le)(le)混凝(ning)土(tu)輸(shu)(shu)送泵的(de)能(neng)力指數概(gai)念(nian)(以(yi)MPa·m3/h為度量(liang)單位);即混凝(ning)土(tu)輸(shu)(shu)送泵的(de)實際出(chu)口壓力與每(mei)小(xiao)時實際輸(shu)(shu)送量(liang)之乘積,該值越大(da),其能(neng)力指數也(ye)越大(da),電機的(de)功率(lv)也(ye)將(jiang)越大(da),由此實現大(da)排(pai)量(liang)、高揚程的(de)目的(de)。科(ke)尼樂公司在設(she)(she)計(ji)時,還采用了(le)(le)高低壓切換的(de)功能(neng)設(she)(she)計(ji),以(yi)滿足不同的(de)施工要求,在經(jing)濟狀態下,又能(neng)產生較(jiao)大(da)的(de)輸(shu)(shu)送量(liang),或者以(yi)相同的(de)電機功率(lv),產生較(jiao)高的(de)出(chu)口壓力。
