37千(qian)(qian)(qian)瓦(wa)(wa)(目前國(guo)內標準混凝土泵,37千(qian)(qian)(qian)瓦(wa)(wa)以(yi)下為細(xi)石(shi)砂漿泵)、45千(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)油(you))、132千(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)油(you))、174千(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)油(you))等等。
選(xuan)擇多大電(dian)機(ji)混凝(ning)土(tu)(tu)泵,首先要考(kao)慮(lv)變(bian)壓(ya)器容(rong)量(liang),其(qi)次考(kao)慮(lv)距離(li)混凝(ning)土(tu)(tu)泵的遠(yuan)近(jin)和線徑大小,以免壓(ya)降過(guo)大造成(cheng)電(dian)流增高(gao)或跳閘停(ting)機(ji),過(guo)大功率造成(cheng)成(cheng)本增加和使用不(bu)便(bian)。電(dian)機(ji)過(guo)小,同時也滿足不(bu)了(le)工程(cheng)需要。
混凝(ning)土輸送泵(beng)功率(lv)、混凝(ning)土輸送泵(beng)出口壓力、混凝(ning)土輸送泵(beng)輸送量之間的關系(xi)。
一(yi)臺混凝(ning)土輸送(song)泵的(de)電機(ji)功率(lv)是(shi)決定出口(kou)壓力和輸送(song)方量的(de)前提條件,在電機(ji)功率(lv)一(yi)定的(de)情況下,壓力的(de)升高必將使(shi)輸送(song)量降低;相反,降低出口(kou)壓力,將會使(shi)輸送(song)量增(zeng)加。
為了保證混凝土(tu)輸(shu)送(song)泵既(ji)要有(you)較大(da)輸(shu)送(song)量(liang),又(you)能有(you)一定的(de)出口(kou)(kou)壓力和(he)與之相匹配的(de)經濟功(gong)(gong)率,在(zai)混凝土(tu)輸(shu)送(song)泵的(de)設計中(zhong),大(da)都采用了恒(heng)功(gong)(gong)率柱塞泵;即恒(heng)功(gong)(gong)率值選(xuan)定后,當出口(kou)(kou)壓力升高時,油泵輸(shu)出排(pai)量(liang)會自(zi)動降低,達到與功(gong)(gong)率設計相對(dui)應的(de)值;如果既(ji)要達到出口(kou)(kou)壓力高,又(you)想得到輸(shu)送(song)量(liang)大(da)的(de)目的(de)。惟一的(de)途徑就(jiu)是增加電機功(gong)(gong)率。
因此,在(zai)(zai)國(guo)家(jia)新標準中,引(yin)用了混凝土輸(shu)送(song)(song)泵的(de)能力(li)指(zhi)數概念(以MPa·m3/h為度量單(dan)位);即混凝土輸(shu)送(song)(song)泵的(de)實際(ji)出口壓力(li)與每小時實際(ji)輸(shu)送(song)(song)量之乘積(ji),該值越大(da)(da)(da),其(qi)能力(li)指(zhi)數也越大(da)(da)(da),電(dian)機(ji)的(de)功(gong)(gong)率(lv)也將越大(da)(da)(da),由此實現大(da)(da)(da)排量、高揚程的(de)目的(de)。科尼(ni)樂公(gong)司在(zai)(zai)設計(ji)時,還(huan)采用了高低(di)壓切換的(de)功(gong)(gong)能設計(ji),以滿足不同(tong)的(de)施工要(yao)求(qiu),在(zai)(zai)經濟狀(zhuang)態(tai)下,又(you)能產(chan)生(sheng)較(jiao)大(da)(da)(da)的(de)輸(shu)送(song)(song)量,或者以相同(tong)的(de)電(dian)機(ji)功(gong)(gong)率(lv),產(chan)生(sheng)較(jiao)高的(de)出口壓力(li)。
