隨著現(xian)代工(gong)(gong)業的(de)(de)(de)興起,以混(hun)凝(ning)(ning)土(tu)為(wei)主材料的(de)(de)(de)建(jian)設方式(shi)已經成為(wei)了建(jian)筑業施(shi)工(gong)(gong)的(de)(de)(de)主要構造之(zhi)一(yi),在(zai)各(ge)種工(gong)(gong)程施(shi)工(gong)(gong)建(jian)設中(zhong)占據了很大(da)的(de)(de)(de)比例,使(shi)得(de)混(hun)凝(ning)(ning)土(tu)機(ji)械的(de)(de)(de)發(fa)展經久不衰,且有(you)越演越烈(lie)的(de)(de)(de)形(xing)勢(shi)。拖(tuo)式(shi)混(hun)凝(ning)(ning)土(tu)泵(beng),簡稱拖(tuo)泵(beng),是(shi)各(ge)種混(hun)凝(ning)(ning)土(tu)機(ji)械中(zhong)的(de)(de)(de)一(yi)種,用于混(hun)凝(ning)(ning)土(tu)施(shi)工(gong)(gong)中(zhong)的(de)(de)(de)輸(shu)送和澆注工(gong)(gong)作(zuo)。
拖泵分類選型
37千(qian)(qian)(qian)(qian)瓦(wa)(目前國內標準混(hun)凝土泵(beng)(beng),37千(qian)(qian)(qian)(qian)瓦(wa)以(yi)下為(wei)細石砂(sha)漿泵(beng)(beng))、45千(qian)(qian)(qian)(qian)瓦(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(柴油)、132千(qian)(qian)(qian)(qian)瓦(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(柴油)、174千(qian)(qian)(qian)(qian)瓦(wa)(柴油)等。
選擇(ze)多大(da)電(dian)機混(hun)凝(ning)土泵,首(shou)先(xian)要考慮變壓器(qi)容量,其次(ci)考慮距離混(hun)凝(ning)土泵的遠近(jin)和線(xian)徑大(da)小,以免壓降過大(da)造成(cheng)(cheng)電(dian)流(liu)增高或跳閘停機,過大(da)功率(lv)造成(cheng)(cheng)成(cheng)(cheng)本增加和使(shi)用不便。電(dian)機過小,同時也滿足(zu)不了工(gong)程需要。
混凝土輸送(song)泵功率(lv)、混凝土輸送(song)泵出口壓力(li)、混凝土輸送(song)泵輸送(song)量之間的關(guan)系
一臺混(hun)凝土輸(shu)送(song)泵(beng)的電機功(gong)率是決定出口壓力和輸(shu)送(song)方量的前提條(tiao)件,在電機功(gong)率一定的情況下,壓力的升高必將使輸(shu)送(song)量降低(di);相反,降低(di)出口壓力,將會使輸(shu)送(song)量增(zeng)加。
為了(le)保(bao)證混凝土輸(shu)送(song)泵(beng)既要有(you)較(jiao)大(da)輸(shu)送(song)量(liang),又(you)(you)能(neng)有(you)一定(ding)(ding)的(de)出口壓力和與之相(xiang)匹(pi)配的(de)經濟(ji)功(gong)(gong)率,在混凝土輸(shu)送(song)泵(beng)的(de)設計(ji)中,大(da)都(dou)采用(yong)了(le)恒功(gong)(gong)率柱(zhu)塞泵(beng);即(ji)恒功(gong)(gong)率值(zhi)選定(ding)(ding)后,當出口壓力升(sheng)高(gao)時,油泵(beng)輸(shu)出排量(liang)會自動降(jiang)低,達到與功(gong)(gong)率設計(ji)相(xiang)對應的(de)值(zhi);如果既要達到出口壓力高(gao),又(you)(you)想得到輸(shu)送(song)量(liang)大(da)的(de)目的(de)。惟一的(de)途徑就是增加電機功(gong)(gong)率。
因此,在(zai)國家新(xin)標準中,引用(yong)了(le)混(hun)凝土(tu)輸(shu)送泵(beng)的(de)(de)能力(li)指數概念(以MPa·m3/h為(wei)度量單位);即混(hun)凝土(tu)輸(shu)送泵(beng)的(de)(de)實(shi)際出口壓力(li)與(yu)每小時實(shi)際輸(shu)送量之乘積,該(gai)值(zhi)越大(da),其能力(li)指數也越大(da),電機的(de)(de)功率也將(jiang)越大(da),由此實(shi)現大(da)排(pai)量、高揚程(cheng)的(de)(de)目的(de)(de)。科尼樂公司在(zai)設計時,還采(cai)用(yong)了(le)高低壓切換(huan)的(de)(de)功能設計,以滿(man)足不同的(de)(de)施工要求,在(zai)經濟狀態下,又能產生(sheng)較大(da)的(de)(de)輸(shu)送量,或者以相同的(de)(de)電機功率,產生(sheng)較高的(de)(de)出口壓力(li)。
