化工(gong)攪拌器有哪些技術的運用

攪拌(ban)器(qi)是一種使液(ye)體、氣體介質強(qiang)迫對流并均(jun)勻混合的(de)(de)器(qi)件.攪拌(ban)器(qi)的(de)(de)類(lei)型、尺寸、轉速(su)、功率等參數，對介質攪拌(ban)混合的(de)(de)效果有著重(zhong)要影響.不同的(de)(de)攪拌(ban)過程需要由不同的(de)(de)攪拌(ban)裝置運行來實現，在(zai)設計選型時首先(xian)要根據工藝對攪拌(ban)作業的(de)(de)目的(de)(de)和要求(qiu)，確(que)定(ding)攪拌(ban)器(qi)的(de)(de)類(lei)型、電動機功率、攪拌(ban)速(su)度，然后選擇減速(su)機、機架(jia)、攪拌(ban)軸、軸封(feng)等各部件.

利用(yong)攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)器(qi)(qi)攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)介質(zhi)，可(ke)以(yi)加(jia)速(su)介質(zhi)的(de)(de)(de)(de)(de)(de)傳(chuan)熱(re)和傳(chuan)質(zhi)，可(ke)以(yi)加(jia)速(su)化工(gong)反應的(de)(de)(de)(de)(de)(de)進行，因而攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)器(qi)(qi)廣泛應用(yong)于石油化工(gong)設備中.攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)器(qi)(qi)種(zhong)(zhong)類型號頗多(duo)，攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)介質(zhi)的(de)(de)(de)(de)(de)(de)種(zhong)(zhong)類也(ye)很廣泛，根據(ju)攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)介質(zhi)物理學(xue)性質(zhi)可(ke)以(yi)分為液(ye)體(ti)(ti)(ti)、固體(ti)(ti)(ti)和氣(qi)體(ti)(ti)(ti)，其(qi)中以(yi)液(ye)體(ti)(ti)(ti)居多(duo).水是(shi)醉常見的(de)(de)(de)(de)(de)(de)液(ye)體(ti)(ti)(ti)之(zhi)一(yi)，它的(de)(de)(de)(de)(de)(de)粘度(du)(du)很低，攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)阻力也(ye)較(jiao)小.液(ye)體(ti)(ti)(ti)攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)介質(zhi)粘度(du)(du)高的(de)(de)(de)(de)(de)(de)也(ye)有(you)，框式攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)器(qi)(qi)，如黃油，在室溫下可(ke)達1 000 000 cP(粘度(du)(du)，1 cP=10-3Pa?s，下同).攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)液(ye)體(ti)(ti)(ti)中氣(qi)體(ti)(ti)(ti)過(guo)多(duo)會起沫，比較(jiao)簡(jian)單的(de)(de)(de)(de)(de)(de)攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)就是(shi)混合兩種(zhong)(zhong)互溶的(de)(de)(de)(de)(de)(de)液(ye)體(ti)(ti)(ti).一(yi)般(ban)而言，攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)裝置由電機(ji)，減速(su)機(ji)，攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)軸，葉輪(lun)組成(cheng)，有(you)時(shi)為方便使用(yong)會配給支架、減速(su)機(ji)等.我(wo)們在設計攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)器(qi)(qi)的(de)(de)(de)(de)(de)(de)時(shi)候(hou)，追求的(de)(de)(de)(de)(de)(de)目標是(shi)攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)器(qi)(qi)工(gong)藝、機(ji)械與成(cheng)本三(san)者間的(de)(de)(de)(de)(de)(de)平衡.我(wo)們的(de)(de)(de)(de)(de)(de)設計師會充(chong)分考慮攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)器(qi)(qi)使用(yong)者的(de)(de)(de)(de)(de)(de)實際需求、攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)器(qi)(qi)的(de)(de)(de)(de)(de)(de)應用(yong)范圍，設計出(chu)可(ke)靠(kao)性高的(de)(de)(de)(de)(de)(de)攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)器(qi)(qi)，防(fang)城港攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)器(qi)(qi)，讓(rang)客戶不為攪(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)器(qi)(qi)的(de)(de)(de)(de)(de)(de)品(pin)質(zhi)、維護等操心.

我們在使用(yong)化(hua)工(gong)攪拌器的時候有時會出現(xian)零(ling)件松動的現(xian)象，那出現(xian)這種現(xian)象的原因是(shi)什么呢？接下來由化(hua)工(gong)攪拌器廠家(jia)來給大(da)家(jia)簡單(dan)分析一下其原因

脫硫攪拌器裝置(zhi)的調試與試運

攪(jiao)拌(ban)器(qi)的轉向，從外面(mian)看(kan)(kan)絕大(da)多數是順(shun)指針轉向，但也(ye)不一(yi)定(ding)，主(zhu)要看(kan)(kan)葉(xie)片安裝情況。葉(xie)片旋轉過程，攪(jiao)拌(ban)器(qi)將槳葉(xie)向斜下方推動漿液，依此判定(ding)攪(jiao)拌(ban)器(qi)旋轉方向。
