具體參數
隨著現代工(gong)(gong)(gong)業的興起,以(yi)混(hun)(hun)凝(ning)土為(wei)(wei)主材(cai)料的建設方式(shi)已經成為(wei)(wei)了建筑(zhu)業施(shi)工(gong)(gong)(gong)的主要構造(zao)之一,在各種工(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)建設中(zhong)占(zhan)據了很大(da)的比例,使得混(hun)(hun)凝(ning)土機械的發展(zhan)經久(jiu)不衰,且(qie)有(you)越演越烈(lie)的形勢(shi)。拖式(shi)混(hun)(hun)凝(ning)土泵(beng),簡(jian)稱拖泵(beng),是各種混(hun)(hun)凝(ning)土機械中(zhong)的一種,用(yong)于混(hun)(hun)凝(ning)土施(shi)工(gong)(gong)(gong)中(zhong)的輸送和澆注工(gong)(gong)(gong)作。
拖泵分類選型
37千(qian)(qian)瓦(wa)(wa)(目前國內標準(zhun)混(hun)凝土(tu)泵,37千(qian)(qian)瓦(wa)(wa)以下為細石砂(sha)漿泵)、45千(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)瓦(wa)(wa)(柴油(you))、132千(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)瓦(wa)(wa)(柴油(you))、174千(qian)(qian)瓦(wa)(wa)(柴油(you))等。
選擇(ze)多大(da)電(dian)機(ji)混凝土(tu)泵,首先要考(kao)慮變壓器(qi)容量,其次考(kao)慮距(ju)離(li)混凝土(tu)泵的(de)遠近和線徑大(da)小(xiao),以免壓降(jiang)過(guo)大(da)造(zao)成(cheng)(cheng)電(dian)流增高或跳閘停機(ji),過(guo)大(da)功率造(zao)成(cheng)(cheng)成(cheng)(cheng)本(ben)增加和使(shi)用不便。電(dian)機(ji)過(guo)小(xiao),同時(shi)也滿足不了工程(cheng)需(xu)要。
混(hun)凝土(tu)輸送泵功(gong)率、混(hun)凝土(tu)輸送泵出口壓力(li)、混(hun)凝土(tu)輸送泵輸送量之間的關系
一臺混凝土輸送(song)泵的電(dian)機(ji)功(gong)率(lv)是決定(ding)出口壓(ya)力(li)(li)和輸送(song)方量的前提條件,在電(dian)機(ji)功(gong)率(lv)一定(ding)的情況下,壓(ya)力(li)(li)的升高必將使(shi)輸送(song)量降低;相反,降低出口壓(ya)力(li)(li),將會使(shi)輸送(song)量增加。
為了保證混凝土輸(shu)(shu)送(song)泵(beng)既(ji)要(yao)有(you)較大(da)輸(shu)(shu)送(song)量(liang),又(you)能有(you)一定的(de)出口(kou)壓力(li)和與之相匹配的(de)經濟功(gong)率,在(zai)混凝土輸(shu)(shu)送(song)泵(beng)的(de)設計(ji)中,大(da)都采用了恒功(gong)率柱塞泵(beng);即恒功(gong)率值選定后,當出口(kou)壓力(li)升高時,油泵(beng)輸(shu)(shu)出排量(liang)會自(zi)動降低,達到與功(gong)率設計(ji)相對應的(de)值;如果既(ji)要(yao)達到出口(kou)壓力(li)高,又(you)想得到輸(shu)(shu)送(song)量(liang)大(da)的(de)目(mu)的(de)。惟一的(de)途徑就(jiu)是增加電機(ji)功(gong)率。
因此,在(zai)(zai)國家新標(biao)準中,引用(yong)了(le)混凝土輸(shu)送(song)泵的(de)(de)(de)能(neng)力指數(shu)概(gai)念(以(yi)MPa·m3/h為度(du)量單位);即混凝土輸(shu)送(song)泵的(de)(de)(de)實(shi)際出(chu)口壓(ya)力與每小(xiao)時(shi)(shi)實(shi)際輸(shu)送(song)量之乘積,該(gai)值(zhi)越大(da),其能(neng)力指數(shu)也越大(da),電機的(de)(de)(de)功率(lv)也將越大(da),由此實(shi)現大(da)排量、高揚程的(de)(de)(de)目(mu)的(de)(de)(de)。科(ke)尼樂公(gong)司在(zai)(zai)設(she)計(ji)時(shi)(shi),還采用(yong)了(le)高低壓(ya)切換(huan)的(de)(de)(de)功能(neng)設(she)計(ji),以(yi)滿足不同(tong)(tong)的(de)(de)(de)施(shi)工要求,在(zai)(zai)經(jing)濟狀(zhuang)態下,又能(neng)產生(sheng)(sheng)較(jiao)大(da)的(de)(de)(de)輸(shu)送(song)量,或者(zhe)以(yi)相同(tong)(tong)的(de)(de)(de)電機功率(lv),產生(sheng)(sheng)較(jiao)高的(de)(de)(de)出(chu)口壓(ya)力。
