隨著現代(dai)工(gong)(gong)業(ye)的(de)(de)(de)興起,以混(hun)凝(ning)土為主材料的(de)(de)(de)建(jian)設方式(shi)已經成為了(le)建(jian)筑業(ye)施(shi)(shi)工(gong)(gong)的(de)(de)(de)主要構造之一,在各種(zhong)工(gong)(gong)程施(shi)(shi)工(gong)(gong)建(jian)設中(zhong)占據了(le)很大的(de)(de)(de)比例(li),使得混(hun)凝(ning)土機械的(de)(de)(de)發展經久不(bu)衰,且有(you)越演(yan)越烈的(de)(de)(de)形勢。拖式(shi)混(hun)凝(ning)土泵,簡稱拖泵,是各種(zhong)混(hun)凝(ning)土機械中(zhong)的(de)(de)(de)一種(zhong),用(yong)于混(hun)凝(ning)土施(shi)(shi)工(gong)(gong)中(zhong)的(de)(de)(de)輸送和(he)澆注工(gong)(gong)作。
拖(tuo)泵分類選(xuan)型(xing)
37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(目前國內標準混凝土泵(beng),37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)以下(xia)為細石(shi)砂漿泵(beng))、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)(chai)油)、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)(chai)油)、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(wa)(wa)(柴(chai)(chai)油)等。
選擇(ze)多大(da)(da)電機混凝(ning)土泵,首先要考慮(lv)變(bian)壓器容量,其次(ci)考慮(lv)距(ju)離混凝(ning)土泵的遠近和線徑大(da)(da)小,以免壓降(jiang)過大(da)(da)造成(cheng)電流增高或跳閘停機,過大(da)(da)功率造成(cheng)成(cheng)本(ben)增加和使用不(bu)便。電機過小,同時也滿足不(bu)了(le)工程需要。
混(hun)凝土(tu)輸(shu)送(song)泵(beng)功(gong)率、混(hun)凝土(tu)輸(shu)送(song)泵(beng)出口壓力、混(hun)凝土(tu)輸(shu)送(song)泵(beng)輸(shu)送(song)量之間的關系
一(yi)臺混凝(ning)土輸(shu)送泵的電(dian)機功率是決定(ding)出口(kou)壓力和輸(shu)送方量(liang)(liang)的前提條(tiao)件(jian),在電(dian)機功率一(yi)定(ding)的情(qing)況下,壓力的升高必將使(shi)(shi)輸(shu)送量(liang)(liang)降低;相反,降低出口(kou)壓力,將會使(shi)(shi)輸(shu)送量(liang)(liang)增加。
為了保證混(hun)凝土輸送(song)泵(beng)(beng)既要(yao)有較大輸送(song)量(liang),又(you)(you)能有一定的(de)出口(kou)壓力(li)和與之(zhi)相匹配的(de)經濟功(gong)(gong)率,在混(hun)凝土輸送(song)泵(beng)(beng)的(de)設(she)計中,大都采(cai)用了恒功(gong)(gong)率柱(zhu)塞(sai)泵(beng)(beng);即恒功(gong)(gong)率值選定后(hou),當出口(kou)壓力(li)升高時,油泵(beng)(beng)輸出排量(liang)會自動降(jiang)低,達到與功(gong)(gong)率設(she)計相對(dui)應的(de)值;如果既要(yao)達到出口(kou)壓力(li)高,又(you)(you)想得到輸送(song)量(liang)大的(de)目的(de)。惟一的(de)途(tu)徑就是增加電機功(gong)(gong)率。
因(yin)此(ci)(ci),在(zai)(zai)(zai)國家新標(biao)準中,引用(yong)了混凝土輸(shu)(shu)(shu)送泵的(de)(de)能(neng)力指數概念(以(yi)MPa·m3/h為度量單位);即混凝土輸(shu)(shu)(shu)送泵的(de)(de)實際出口(kou)(kou)壓(ya)(ya)力與(yu)每(mei)小(xiao)時實際輸(shu)(shu)(shu)送量之乘積,該值越大(da),其能(neng)力指數也越大(da),電(dian)機(ji)的(de)(de)功(gong)率也將越大(da),由此(ci)(ci)實現(xian)大(da)排量、高(gao)揚程(cheng)的(de)(de)目的(de)(de)。科尼樂公司(si)在(zai)(zai)(zai)設(she)(she)計時,還采(cai)用(yong)了高(gao)低(di)壓(ya)(ya)切(qie)換的(de)(de)功(gong)能(neng)設(she)(she)計,以(yi)滿足(zu)不同的(de)(de)施(shi)工要求,在(zai)(zai)(zai)經濟狀態下,又能(neng)產生(sheng)較(jiao)(jiao)大(da)的(de)(de)輸(shu)(shu)(shu)送量,或(huo)者以(yi)相(xiang)同的(de)(de)電(dian)機(ji)功(gong)率,產生(sheng)較(jiao)(jiao)高(gao)的(de)(de)出口(kou)(kou)壓(ya)(ya)力。
