隨著現(xian)代工(gong)(gong)業的(de)(de)(de)(de)興(xing)起(qi),以混凝(ning)土為主(zhu)材料的(de)(de)(de)(de)建設方式已經(jing)成為了建筑業施工(gong)(gong)的(de)(de)(de)(de)主(zhu)要構造之一,在各種(zhong)工(gong)(gong)程施工(gong)(gong)建設中占據了很(hen)大(da)的(de)(de)(de)(de)比例,使(shi)得混凝(ning)土機械的(de)(de)(de)(de)發(fa)展(zhan)經(jing)久不衰(shuai),且有越演越烈的(de)(de)(de)(de)形勢。拖式混凝(ning)土泵,簡(jian)稱拖泵,是各種(zhong)混凝(ning)土機械中的(de)(de)(de)(de)一種(zhong),用于混凝(ning)土施工(gong)(gong)中的(de)(de)(de)(de)輸(shu)送和澆(jiao)注工(gong)(gong)作。
拖泵分類選型
37千(qian)瓦(wa)(wa)(目(mu)前(qian)國(guo)內(nei)標準混(hun)凝(ning)土泵,37千(qian)瓦(wa)(wa)以(yi)下為細石砂(sha)漿(jiang)泵)、45千(qian)瓦(wa)(wa)、55千(qian)瓦(wa)(wa)、75千(qian)瓦(wa)(wa)、90千(qian)瓦(wa)(wa)、110千(qian)瓦(wa)(wa)、130千(qian)瓦(wa)(wa)(柴(chai)油(you))、132千(qian)瓦(wa)(wa)、162千(qian)瓦(wa)(wa)(柴(chai)油(you))、174千(qian)瓦(wa)(wa)(柴(chai)油(you))等(deng)。
選(xuan)擇(ze)多大(da)電機(ji)(ji)混凝土泵,首先要考(kao)慮變壓(ya)器容量,其次考(kao)慮距離混凝土泵的遠近和線徑大(da)小,以(yi)免壓(ya)降(jiang)過(guo)(guo)大(da)造(zao)成(cheng)電流增高或跳閘停機(ji)(ji),過(guo)(guo)大(da)功率(lv)造(zao)成(cheng)成(cheng)本增加和使用不便。電機(ji)(ji)過(guo)(guo)小,同時也(ye)滿(man)足不了工(gong)程需要。
混(hun)凝(ning)土輸(shu)送(song)泵(beng)功率(lv)、混(hun)凝(ning)土輸(shu)送(song)泵(beng)出口壓力(li)、混(hun)凝(ning)土輸(shu)送(song)泵(beng)輸(shu)送(song)量之間的關(guan)系
一(yi)臺混凝土(tu)輸送(song)泵的(de)電(dian)機功率是決定出口壓力和輸送(song)方量的(de)前提(ti)條件,在電(dian)機功率一(yi)定的(de)情況下(xia),壓力的(de)升高必將使(shi)輸送(song)量降低;相反,降低出口壓力,將會使(shi)輸送(song)量增加。
為了(le)保證混(hun)凝土輸(shu)(shu)(shu)(shu)送(song)(song)泵既(ji)要有(you)較大輸(shu)(shu)(shu)(shu)送(song)(song)量(liang),又(you)能有(you)一定的(de)(de)出口壓(ya)力(li)和與(yu)之相(xiang)匹配的(de)(de)經濟功(gong)(gong)(gong)(gong)率,在(zai)混(hun)凝土輸(shu)(shu)(shu)(shu)送(song)(song)泵的(de)(de)設計中,大都(dou)采用了(le)恒功(gong)(gong)(gong)(gong)率柱塞(sai)泵;即恒功(gong)(gong)(gong)(gong)率值選(xuan)定后,當出口壓(ya)力(li)升高時,油泵輸(shu)(shu)(shu)(shu)出排量(liang)會(hui)自動降低,達到與(yu)功(gong)(gong)(gong)(gong)率設計相(xiang)對(dui)應的(de)(de)值;如果(guo)既(ji)要達到出口壓(ya)力(li)高,又(you)想得到輸(shu)(shu)(shu)(shu)送(song)(song)量(liang)大的(de)(de)目(mu)的(de)(de)。惟一的(de)(de)途徑就(jiu)是增(zeng)加電機功(gong)(gong)(gong)(gong)率。
因此,在(zai)國家新標(biao)準中(zhong),引用(yong)了混凝(ning)土輸(shu)(shu)(shu)送(song)(song)泵的(de)(de)(de)(de)能力(li)指數(shu)概念(以MPa·m3/h為度量單位);即混凝(ning)土輸(shu)(shu)(shu)送(song)(song)泵的(de)(de)(de)(de)實(shi)(shi)際(ji)出口(kou)壓力(li)與每小時(shi)實(shi)(shi)際(ji)輸(shu)(shu)(shu)送(song)(song)量之乘積,該(gai)值(zhi)越(yue)大(da)(da),其(qi)能力(li)指數(shu)也越(yue)大(da)(da),電機的(de)(de)(de)(de)功率(lv)也將越(yue)大(da)(da),由此實(shi)(shi)現大(da)(da)排量、高揚(yang)程的(de)(de)(de)(de)目的(de)(de)(de)(de)。科(ke)尼樂公司在(zai)設(she)計(ji)時(shi),還采用(yong)了高低壓切換的(de)(de)(de)(de)功能設(she)計(ji),以滿足不同的(de)(de)(de)(de)施(shi)工要(yao)求(qiu),在(zai)經濟狀態下,又能產生(sheng)較(jiao)大(da)(da)的(de)(de)(de)(de)輸(shu)(shu)(shu)送(song)(song)量,或者以相同的(de)(de)(de)(de)電機功率(lv),產生(sheng)較(jiao)高的(de)(de)(de)(de)出口(kou)壓力(li)。
