具體參數
隨著現(xian)代工(gong)(gong)(gong)(gong)業(ye)的(de)興起(qi),以混(hun)凝(ning)土(tu)為主材料的(de)建(jian)(jian)設(she)(she)方式(shi)已經成為了建(jian)(jian)筑業(ye)施工(gong)(gong)(gong)(gong)的(de)主要構造(zao)之一,在(zai)各種工(gong)(gong)(gong)(gong)程施工(gong)(gong)(gong)(gong)建(jian)(jian)設(she)(she)中占據(ju)了很大的(de)比(bi)例,使得混(hun)凝(ning)土(tu)機械的(de)發(fa)展經久(jiu)不衰,且有越(yue)演(yan)越(yue)烈的(de)形(xing)勢(shi)。拖式(shi)混(hun)凝(ning)土(tu)泵,簡稱拖泵,是(shi)各種混(hun)凝(ning)土(tu)機械中的(de)一種,用于混(hun)凝(ning)土(tu)施工(gong)(gong)(gong)(gong)中的(de)輸送和(he)澆注工(gong)(gong)(gong)(gong)作。
拖泵分(fen)類選型
37千(qian)(qian)(qian)(qian)瓦(wa)(wa)(目前國內標準混凝土(tu)泵,37千(qian)(qian)(qian)(qian)瓦(wa)(wa)以(yi)下(xia)為細石砂漿泵)、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。
選擇多大電機(ji)(ji)混凝土泵(beng),首先(xian)要(yao)考慮(lv)變壓(ya)器(qi)容量,其(qi)次考慮(lv)距離混凝土泵(beng)的(de)遠近和線徑(jing)大小(xiao),以免壓(ya)降過(guo)大造成電流增高或跳閘停機(ji)(ji),過(guo)大功率造成成本(ben)增加和使用不(bu)便。電機(ji)(ji)過(guo)小(xiao),同時也(ye)滿足不(bu)了工程需要(yao)。
混凝土輸(shu)送(song)(song)泵(beng)功率、混凝土輸(shu)送(song)(song)泵(beng)出口壓(ya)力(li)、混凝土輸(shu)送(song)(song)泵(beng)輸(shu)送(song)(song)量之間的關(guan)系
一臺(tai)混凝土輸送泵的電機功率是決(jue)定(ding)出(chu)(chu)口壓(ya)(ya)力(li)和(he)輸送方(fang)量(liang)的前提(ti)條件(jian),在電機功率一定(ding)的情況下,壓(ya)(ya)力(li)的升高必將使輸送量(liang)降(jiang)低;相反,降(jiang)低出(chu)(chu)口壓(ya)(ya)力(li),將會使輸送量(liang)增加。
為了保證混(hun)凝(ning)土輸(shu)送(song)泵(beng)既要(yao)有較大輸(shu)送(song)量(liang),又(you)能有一定(ding)的(de)出(chu)口(kou)壓力和與之(zhi)相匹配的(de)經濟功(gong)率,在混(hun)凝(ning)土輸(shu)送(song)泵(beng)的(de)設(she)計(ji)(ji)中(zhong),大都采用(yong)了恒功(gong)率柱塞泵(beng);即恒功(gong)率值(zhi)選定(ding)后(hou),當出(chu)口(kou)壓力升高(gao)時,油泵(beng)輸(shu)出(chu)排量(liang)會自動降低,達(da)到(dao)與功(gong)率設(she)計(ji)(ji)相對應的(de)值(zhi);如果既要(yao)達(da)到(dao)出(chu)口(kou)壓力高(gao),又(you)想得(de)到(dao)輸(shu)送(song)量(liang)大的(de)目的(de)。惟(wei)一的(de)途徑就是(shi)增加電機功(gong)率。
因此(ci),在國家(jia)新標準中,引(yin)用(yong)了混(hun)(hun)凝(ning)土(tu)輸送(song)泵的能力(li)(li)指(zhi)數概念(以(yi)MPa·m3/h為度量(liang)(liang)單位);即(ji)混(hun)(hun)凝(ning)土(tu)輸送(song)泵的實(shi)際出口(kou)壓(ya)力(li)(li)與每小時實(shi)際輸送(song)量(liang)(liang)之(zhi)乘積,該(gai)值越大,其能力(li)(li)指(zhi)數也越大,電機的功率(lv)也將越大,由此(ci)實(shi)現大排量(liang)(liang)、高揚程的目的。科尼樂公司在設(she)計時,還采用(yong)了高低(di)壓(ya)切換的功能設(she)計,以(yi)滿(man)足不同的施(shi)工要(yao)求,在經(jing)濟狀態下,又能產(chan)生較大的輸送(song)量(liang)(liang),或者以(yi)相同的電機功率(lv),產(chan)生較高的出口(kou)壓(ya)力(li)(li)。
