37千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(目前國內標(biao)準混凝土泵(beng),37千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)以下(xia)為(wei)細石砂漿泵(beng))、45千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、55千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、75千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、90千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、110千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、130千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴油)、132千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴油)、174千(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴油)等等。
選擇(ze)多(duo)大電(dian)機(ji)(ji)混(hun)凝土泵,首先要考慮(lv)變壓器(qi)容量,其次考慮(lv)距離混(hun)凝土泵的(de)遠近和(he)線徑大小,以免壓降過(guo)大造成電(dian)流增(zeng)高或跳(tiao)閘停(ting)機(ji)(ji),過(guo)大功率造成成本(ben)增(zeng)加和(he)使(shi)用不便。電(dian)機(ji)(ji)過(guo)小,同(tong)時也滿足不了工程需要。
混(hun)凝土輸(shu)(shu)送(song)泵(beng)(beng)(beng)功(gong)率、混(hun)凝土輸(shu)(shu)送(song)泵(beng)(beng)(beng)出(chu)口(kou)壓(ya)力、混(hun)凝土輸(shu)(shu)送(song)泵(beng)(beng)(beng)輸(shu)(shu)送(song)量(liang)之間的關系
一臺(tai)混凝土輸送(song)泵的電機(ji)功率是決(jue)定出(chu)(chu)口(kou)(kou)壓力和輸送(song)方量(liang)(liang)的前(qian)提條件(jian),在電機(ji)功率一定的情況下,壓力的升高必將使輸送(song)量(liang)(liang)降低(di);相反,降低(di)出(chu)(chu)口(kou)(kou)壓力,將會使輸送(song)量(liang)(liang)增加。
為了(le)保證混(hun)凝土輸送(song)泵(beng)(beng)既要有較大輸送(song)量,又能有一(yi)定的出(chu)(chu)口(kou)壓(ya)力(li)和與之相(xiang)匹配的經(jing)濟(ji)功率(lv)(lv)(lv),在混(hun)凝土輸送(song)泵(beng)(beng)的設(she)計中,大都采用了(le)恒功率(lv)(lv)(lv)柱(zhu)塞泵(beng)(beng);即(ji)恒功率(lv)(lv)(lv)值選(xuan)定后,當出(chu)(chu)口(kou)壓(ya)力(li)升高(gao)時,油泵(beng)(beng)輸出(chu)(chu)排量會(hui)自動降低(di),達(da)到(dao)與功率(lv)(lv)(lv)設(she)計相(xiang)對應的值;如果既要達(da)到(dao)出(chu)(chu)口(kou)壓(ya)力(li)高(gao),又想得到(dao)輸送(song)量大的目的。惟一(yi)的途徑就是增加電機(ji)功率(lv)(lv)(lv)。
因此(ci),在(zai)國家新標準中(zhong),引用(yong)了(le)混凝(ning)(ning)土(tu)(tu)輸(shu)(shu)送(song)泵(beng)的能(neng)力指數概念(以MPa·m3/h為度量單位(wei));即(ji)混凝(ning)(ning)土(tu)(tu)輸(shu)(shu)送(song)泵(beng)的實(shi)際(ji)出(chu)口壓力與(yu)每小時實(shi)際(ji)輸(shu)(shu)送(song)量之乘積,該值越(yue)大(da),其能(neng)力指數也越(yue)大(da),電機的功(gong)率(lv)也將越(yue)大(da),由此(ci)實(shi)現大(da)排(pai)量、高(gao)(gao)揚(yang)程的目的。科尼(ni)樂(le)公司在(zai)設計(ji)時,還采用(yong)了(le)高(gao)(gao)低(di)壓切換(huan)的功(gong)能(neng)設計(ji),以滿(man)足不同的施(shi)工要求,在(zai)經濟狀態下,又(you)能(neng)產生(sheng)較大(da)的輸(shu)(shu)送(song)量,或者以相同的電機功(gong)率(lv),產生(sheng)較高(gao)(gao)的出(chu)口壓力。
