隨著現(xian)代工(gong)業的(de)(de)興起,以混(hun)凝土(tu)(tu)(tu)為(wei)主材(cai)料(liao)的(de)(de)建(jian)設方(fang)式(shi)已經(jing)成為(wei)了建(jian)筑業施(shi)工(gong)的(de)(de)主要(yao)構(gou)造之一(yi),在各種工(gong)程施(shi)工(gong)建(jian)設中(zhong)占(zhan)據(ju)了很大的(de)(de)比例,使得混(hun)凝土(tu)(tu)(tu)機械(xie)的(de)(de)發(fa)展經(jing)久不衰,且(qie)有越演越烈的(de)(de)形勢(shi)。拖(tuo)式(shi)混(hun)凝土(tu)(tu)(tu)泵,簡稱拖(tuo)泵,是各種混(hun)凝土(tu)(tu)(tu)機械(xie)中(zhong)的(de)(de)一(yi)種,用于混(hun)凝土(tu)(tu)(tu)施(shi)工(gong)中(zhong)的(de)(de)輸送和澆注(zhu)工(gong)作。
拖泵分類選型
37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(目前國內標準混凝土(tu)泵(beng),37千(qian)(qian)(qian)(qian)瓦(wa)(wa)以下為細石砂漿泵(beng))、45千(qian)(qian)(qian)(qian)瓦(wa)(wa)、55千(qian)(qian)(qian)(qian)瓦(wa)(wa)、75千(qian)(qian)(qian)(qian)瓦(wa)(wa)、90千(qian)(qian)(qian)(qian)瓦(wa)(wa)、110千(qian)(qian)(qian)(qian)瓦(wa)(wa)、130千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)油)、132千(qian)(qian)(qian)(qian)瓦(wa)(wa)、162千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)油)、174千(qian)(qian)(qian)(qian)瓦(wa)(wa)(柴(chai)油)等。
選(xuan)擇多(duo)大電機(ji)混凝土泵,首先要考慮變壓(ya)器容量,其(qi)次(ci)考慮距離混凝土泵的遠近和線徑大小(xiao),以(yi)免壓(ya)降過(guo)大造成(cheng)電流(liu)增高或跳閘停機(ji),過(guo)大功(gong)率造成(cheng)成(cheng)本增加和使用不便。電機(ji)過(guo)小(xiao),同時也滿足不了工程需要。
混凝土(tu)輸(shu)(shu)(shu)送(song)泵(beng)功(gong)率、混凝土(tu)輸(shu)(shu)(shu)送(song)泵(beng)出口壓力、混凝土(tu)輸(shu)(shu)(shu)送(song)泵(beng)輸(shu)(shu)(shu)送(song)量之間(jian)的關(guan)系
一臺混凝土(tu)輸送(song)(song)泵的(de)電(dian)(dian)機功率是決定(ding)出口(kou)壓(ya)力和輸送(song)(song)方量的(de)前提條件,在(zai)電(dian)(dian)機功率一定(ding)的(de)情況(kuang)下,壓(ya)力的(de)升(sheng)高必將使輸送(song)(song)量降低(di);相反(fan),降低(di)出口(kou)壓(ya)力,將會使輸送(song)(song)量增加(jia)。
為了保證混凝(ning)土輸送(song)(song)泵(beng)既(ji)要有較大(da)輸送(song)(song)量(liang),又(you)(you)能有一定的(de)(de)出口壓力(li)和與(yu)之相匹配(pei)的(de)(de)經(jing)濟(ji)功(gong)率,在混凝(ning)土輸送(song)(song)泵(beng)的(de)(de)設計中(zhong),大(da)都(dou)采(cai)用(yong)了恒(heng)功(gong)率柱塞泵(beng);即恒(heng)功(gong)率值選定后,當出口壓力(li)升高(gao)時,油(you)泵(beng)輸出排量(liang)會自(zi)動降低,達(da)到與(yu)功(gong)率設計相對應的(de)(de)值;如果既(ji)要達(da)到出口壓力(li)高(gao),又(you)(you)想得到輸送(song)(song)量(liang)大(da)的(de)(de)目的(de)(de)。惟一的(de)(de)途徑就是增加電機功(gong)率。
因此,在(zai)國家新標準中,引(yin)用了混凝土輸送(song)(song)泵的(de)(de)(de)能(neng)力指(zhi)數(shu)概(gai)念(以MPa·m3/h為度量單位);即混凝土輸送(song)(song)泵的(de)(de)(de)實際(ji)(ji)出(chu)口壓力與每小時實際(ji)(ji)輸送(song)(song)量之(zhi)乘積,該值越大,其能(neng)力指(zhi)數(shu)也越大,電機(ji)(ji)的(de)(de)(de)功率(lv)也將越大,由(you)此實現大排(pai)量、高(gao)揚(yang)程的(de)(de)(de)目的(de)(de)(de)。科尼樂公司在(zai)設計時,還采用了高(gao)低壓切換(huan)的(de)(de)(de)功能(neng)設計,以滿足不(bu)同的(de)(de)(de)施工要(yao)求,在(zai)經(jing)濟狀態下,又(you)能(neng)產生較(jiao)(jiao)大的(de)(de)(de)輸送(song)(song)量,或者(zhe)以相同的(de)(de)(de)電機(ji)(ji)功率(lv),產生較(jiao)(jiao)高(gao)的(de)(de)(de)出(chu)口壓力。
