管殼式換熱器又稱列管式換熱器。是以封閉在殼體中管束的壁面作為傳熱面的間壁式換熱器。這種換熱器結構較簡單，操作可靠，可用各種結構材料制造，能在高溫、高壓下使用，是目前應用廣泛的類型。供應熱水機組價格在使用一段時間之后對管殼式換熱器清洗非常的重要，一般由于工業上使用長久管殼式換熱器里面的管道會出現各種灰塵和沉淀物的粘黏，導致換熱效率下降，變相提高生產成本，嚴重還會導致管殼式換熱器使用壽命，造成損失。熱水機組清洗有利于提高換(huan)熱效(xiao)率(lv):管殼(ke)式換(huan)熱器或管道(dao)運(yun)行一(yi)段時間后(hou)，表面(mian)往往會結一(yi)層污垢(gou)，污垢(gou)一(yi)般(ban)較為致(zhi)密(mi)堅硬，熱導率(lv)很小(xiao)。污垢(gou)的阻礙效(xiao)率(lv)大得驚(jing)人，里面(mian)的有機離子(zi)、灰塵若無重視可(ke)能導致(zhi)不可(ke)避(bi)免的其他問題的產(chan)生。

換熱器(qi)(qi)板(ban)(ban)(ban)片拆(chai)開(kai)前,應丈量板(ban)(ban)(ban)束的壓(ya)緊長度(du)尺度(du),做好(hao)記錄(重裝時應按此(ci)(ci)尺度(du)). b.密(mi)封(feng)墊(dian)(dian)片若(ruo)粘在兩板(ban)(ban)(ban)片間(jian)的溝槽(cao)(cao)內,此(ci)(ci)刻(ke)需用(yong)(yong)螺絲刀小(xiao)心腸(chang)將其(qi)分隔(ge),螺絲刀應先從易剝開(kai)的部位插入,然(ran)后沿其(qi)周邊進(jin)行別離(li),切(qie)不(bu)可損(sun)壞(huai)換熱器(qi)(qi)板(ban)(ban)(ban)片和密(mi)封(feng)墊(dian)(dian)片 替換新密(mi)封(feng)墊(dian)(dian)片時,需要用(yong)(yong)丙酮或其(qi)他酮類有(you)機(ji)溶劑,將密(mi)封(feng)墊(dian)(dian)片溝槽(cao)(cao)擦(ca)凈.再(zai)用(yong)(yong)毛刷將合成樹(shu)脂粘接劑均(jun)勻涂在溝槽(cao)(cao)里..查看換熱器(qi)(qi)板(ban)(ban)(ban)片是否有(you)穿孔,一般用(yong)(yong)5倍的放大鏡,有(you)時也可用(yong)(yong)燈火(huo)或火(huo)油(you)滲透法等逐片查看.e.假如發現介(jie)質出入口短管及通道有(you)雜(za)物(wu)堆積(ji),則闡明過濾器(qi)(qi)失效,應及時清洗(xi).
