style="text-indent:25px">管殼式換熱器，研究表明工業(yè)水無(wú)論是淡水還是海水，都會(huì)有各種離子和溶解的氧氣，其中氯離子和氧的濃度變化，對(duì)金屬的腐蝕形狀起重要作用。另外，金屬結(jié)構(gòu)的復(fù)雜程度也會(huì)影響腐蝕形態(tài)。因此，管板與列管焊縫的腐蝕以孔蝕和縫隙腐蝕為主。從外觀看，管板表面會(huì)有許多腐蝕產(chǎn)物和積沉物，分布著大小不等的凹坑。以海水為介質(zhì)時(shí)，還會(huì)產(chǎn)生電偶腐蝕?；瘜W(xué)腐蝕就是介質(zhì)的腐蝕，換熱器管板接觸各種各樣的化學(xué)介質(zhì)，就會(huì)受到化學(xué)介質(zhì)的腐蝕。另外，換熱器管板還會(huì)與換熱管之間產(chǎn)生一定的雙金屬腐蝕。換熱器的折流檔板使湍動(dòng)程度大為增加。河南換熱器廠家排名</p><p

style="text-indent:25px">換熱器的冷凝器也有立式及臥式兩種。臥式和立式冷凝器二者除安放位置和水的分配不同外，水的溫升和用水量也不一樣。立式冷凝器的冷卻水是沿著重力沿管內(nèi)壁往下的流，只能是單行程，故要得到足夠大的傳熱系數(shù)，就必須使用大量的水。臥式冷凝器是用泵將冷卻水壓送到冷卻管內(nèi)，故可制成多行程式冷凝器，且冷卻水可以得到足夠大的流速和溫升。所以臥式冷凝器用少量的冷卻水就可以得到足夠大的傳熱效果。但過(guò)分地加大流速，傳熱系數(shù)增大不多，而冷卻水泵的功耗卻明顯增加。河南換熱器廠家排名</p></p><br
