冷凝換熱器

簡介

由兩只(zhi)相同(tong)面積的冷(leng)油器和(he)三通閥裝(zhuang)置構成，一(yi)只(zhi)工(gong)作，一(yi)只(zhi)備用，每個(ge)冷(leng)卻(que)器能承(cheng)擔整個(ge)系統的冷(leng)卻(que)負荷，管板一(yi)頭固定，一(yi)頭浮(fu)動、可拆卸的管束和(he)水室(shi)箱蓋(gai)，便(bian)于運首(shou)(shou)*首(shou)(shou)*首(shou)(shou)*首(shou)(shou)*首(shou)(shou)*首(shou)(shou)*首(shou)(shou)先進行過程中清(qing)洗、檢查和(he)維修。

冷(leng)卻器的(de)材質(zhi)，根據使用場所、水(shui)系統條件(jian)可(ke)有(you)多(duo)種選擇。材質(zhi)有(you)全(quan)不銹(xiu)鋼，不銹(xiu)鋼碳(tan)鋼組合，碳(tan)鋼和銅(tong)組合等。

特(te)點

1、采用(yong)裸(luo)管(guan)(guan)（表面未(wei)軋翅(chi)片）式(shi)傳(chuan)熱管(guan)(guan)，管(guan)(guan)外界膜傳(chuan)熱系數高，抗污(wu)染能力(li)強。

2、冷卻管(guan)采用優質紫銅管(guan)，并加工成(cheng)翅片(pian)形散熱片(pian)，產(chan)品體積小、熱交(jiao)換面積大。

3、列管式(shi)冷卻器螺(luo)旋(xuan)形導流(liu)板(ban)，使被(bei)冷卻液體成螺(luo)旋(xuan)形連續(xu)均(jun)勻滾(gun)動(dong)流(liu)動(dong)，克服(fu)了折流(liu)式(shi)導板(ban)所產(chan)生的(de)冷熱交換效率。

4、采用(yong)脹管式封口，克(ke)服了材料經高溫焊接后產(chan)生的不良變化。

5、結構(gou)性能良好，密封性能穩(wen)定，傳熱效率高、結構(gou)緊湊(cou)、占(zhan)地面小。

應用

列(lie)管式冷卻器廣泛應用于冶金、礦山、水泥(ni)、電力、輕工、食(shi)品(pin)、化工、造紙等工業(ye)部門(men)的稀(xi)油(you)潤滑系統和(he)液壓系統中用來冷卻系統中的潤滑油(you)、液壓油(you)等首(shou)*首(shou)*首(shou)*首(shou)*首(shou)*首(shou)*首(shou)先進行業(ye)領域。

水垢的清洗

1、物(wu)理清洗辦法(fa)：固定管板式(shi)的可以用水泵刷子(zi)沖(chong)洗，如果是抽芯式(shi)即浮頭式(shi)的即可把(ba)管束抽出(chu)來沖(chong)洗；

2、化(hua)學清洗(xi)：方法(fa)當積垢由疏松變為(wei)(wei)致(zhi)密、硬質(zhi)后，采用(yong)機(ji)械清洗(xi)方法(fa)己達(da)不到清垢的，此時宜采用(yong)酸洗(xi)的方法(fa)。鹽(yan)(yan)酸不用(yong)預熱就能(neng)容易地(di)溶解(jie)碳酸鈣和(he)(he)碳酸鎂水垢，因此酸洗(xi)液一般為(wei)(wei)常溫鹽(yan)(yan)酸溶液。酸洗(xi)雖(sui)然能(neng)很好的疏松水垢和(he)(he)恢(hui)復冷卻(que)器表面(mian)的正常狀態，但(dan)鹽(yan)(yan)酸對冷卻(que)銅管(guan)有腐蝕(shi)作用(yong)。為(wei)(wei)了保護冷卻(que)器管(guan)壁(bi)不受鹽(yan)(yan)酸的侵蝕(shi)，在(zai)酸洗(xi)液內必須加入(ru)添(tian)加劑，即強烈地(di)遲(chi)滯金(jin)屬溶解(jie)過程的物質(zhi)。我(wo)們選(xuan)用(yong)的添(tian)加劑為(wei)(wei)苯駢三氮唑(zuo)，即BC-801水穩定劑，使用(yong)濃度為(wei)(wei)3%左右。根據(ju)經(jing)驗，若能(neng)夠(gou)按時進首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)先進行機(ji)械清洗(xi)，酸洗(xi)可(ke)2a--3a進首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)先進行1次；反之，需每年進首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)*首(shou)(shou)(shou)(shou)(shou)先進行1次酸洗(xi)。
