冷(leng)凝器(qi)(qi)在(zai)脹(zhang)(zhang)(zhang)管(guan)(guan)(guan)束時，如有密封(feng)焊(han)加(jia)(jia)強度(du)脹(zhang)(zhang)(zhang)或(huo)強度(du)焊(han)加(jia)(jia)貼(tie)脹(zhang)(zhang)(zhang)，都要行焊(han)接后再脹(zhang)(zhang)(zhang)接，因(yin)先脹(zhang)(zhang)(zhang)后焊(han)易形成氣孔(kong)，耐腐蝕(shi)換(huan)熱器(qi)(qi)供應商，影(ying)響密封(feng)性能。只進(jin)行脹(zhang)(zhang)(zhang)接的(de)(de)(de)管(guan)(guan)(guan)子(zi)在(zai)脹(zhang)(zhang)(zhang)管(guan)(guan)(guan)前(qian)要先將管(guan)(guan)(guan)子(zi)的(de)(de)(de)一端固(gu)定，另(ling)一端便可開始脹(zhang)(zhang)(zhang)接。把冷(leng)凝器(qi)(qi)斜(xie)柱式固(gu)定脹(zhang)(zhang)(zhang)管(guan)(guan)(guan)器(qi)(qi)放(fang)到已經裝(zhuang)好在(zai)管(guan)(guan)(guan)板中(zhong)的(de)(de)(de)管(guan)(guan)(guan)頭(tou)里，用(yong)手推(tui)進(jin)脹(zhang)(zhang)(zhang)桿，使(shi)滾柱張開把脹(zhang)(zhang)(zhang)管(guan)(guan)(guan)器(qi)(qi)是外殼穩住，耐腐蝕(shi)換(huan)熱器(qi)(qi)銷售，并與(yu)(yu)管(guan)(guan)(guan)子(zi)的(de)(de)(de)內壁(bi)靠緊(jin)，使(shi)外殼上的(de)(de)(de)止推(tui)盤與(yu)(yu)管(guan)(guan)(guan)頭(tou)之間(jian)保持10~20mm，然后用(yong)扳手轉動脹(zhang)(zhang)(zhang)桿或(huo)啟動電動裝(zhuang)置，脹(zhang)(zhang)(zhang)管(guan)(guan)(guan)器(qi)(qi)便開始工作。這時滾柱在(zai)管(guan)(guan)(guan)中(zhong)滾壓(ya)并和外殼旋轉，整個脹(zhang)(zhang)(zhang)管(guan)(guan)(guan)器(qi)(qi)向前(qian)推(tui)進(jin)，當管(guan)(guan)(guan)子(zi)脹(zhang)(zhang)(zhang)到與(yu)(yu)管(guan)(guan)(guan)孔(kong)完全接合時，由于止推(tui)盤靠著管(guan)(guan)(guan)頭(tou)而使(shi)脹(zhang)(zhang)(zhang)管(guan)(guan)(guan)器(qi)(qi)不能推(tui)進(jin)，緊(jin)固(gu)脹(zhang)(zhang)(zhang)管(guan)(guan)(guan)的(de)(de)(de)步驟就完成了。

冷(leng)(leng)凝器(qi)溫度偏(pian)低(di)的(de)原因及(ji)排除方(fang)法：1.冷(leng)(leng)卻水(shui)進水(shui)溫度偏(pian)低(di)或(huo)冷(leng)(leng)卻水(shui)流量(liang)太(tai)大。此時可以(yi)(yi)通(tong)(tong)過(guo)間歇啟動(dong)冷(leng)(leng)卻塔風機(ji)等方(fang)式提高冷(leng)(leng)卻水(shui)進水(shui)溫度；同時，可以(yi)(yi)通(tong)(tong)過(guo)開啟冷(leng)(leng)卻水(shui)旁通(tong)(tong)閥來減小冷(leng)(leng)卻水(shui)流量(liang)。2.系(xi)統制(zhi)冷(leng)(leng)劑(ji)泄露過(guo)多或(huo)充(chong)注量(liang)不足。處(chu)理方(fang)法：查處(chu)泄漏(lou)點(dian)，補漏(lou)后(hou)加足制(zhi)冷(leng)(leng)劑(ji)。3.冷(leng)(leng)凝器(qi)壓力(li)表連(lian)接(jie)管(guan)彎曲、阻塞。所以(yi)(yi)，冷(leng)(leng)凝器(qi)壓力(li)表連(lian)接(jie)管(guan)不宜過(guo)長，避免(mian)因管(guan)子彎圈，葫蘆島耐腐蝕換熱器(qi)，制(zhi)冷(leng)(leng)劑(ji)在連(lian)接(jie)管(guan)中(zhong)凝結，引(yin)起(qi)阻塞。

蒸汽冷凝器

蒸(zheng)汽(qi)冷(leng)(leng)(leng)凝器(qi)這種冷(leng)(leng)(leng)凝常應用于多效(xiao)蒸(zheng)發(fa)器(qi)末(mo)效(xiao)二次蒸(zheng)汽(qi)的冷(leng)(leng)(leng)凝，保(bao)證末(mo)效(xiao)蒸(zheng)發(fa)器(qi)的真(zhen)空(kong)(kong)度。例(li)（1）噴淋式(shi)冷(leng)(leng)(leng)凝器(qi)，冷(leng)(leng)(leng)水從(cong)上部(bu)噴嘴噴入，蒸(zheng)汽(qi)從(cong)側面入口(kou)進(jin)入，蒸(zheng)汽(qi)與(yu)冷(leng)(leng)(leng)水充分接(jie)觸后被(bei)冷(leng)(leng)(leng)凝為(wei)水，同時沿(yan)(yan)管(guan)(guan)下流，部(bu)分不凝汽(qi)體也可能被(bei)帶(dai)出(chu)。例(li)（2）充填式(shi)冷(leng)(leng)(leng)凝器(qi)，蒸(zheng)汽(qi)從(cong)側管(guan)(guan)進(jin)入后一(yi)上面噴下的冷(leng)(leng)(leng)水相接(jie)觸冷(leng)(leng)(leng)凝器(qi)里面裝了滿(man)了瓷環填料(liao)，填料(liao)被(bei)水淋濕后，增大了冷(leng)(leng)(leng)水與(yu)蒸(zheng)汽(qi)的接(jie)觸面積，蒸(zheng)汽(qi)冷(leng)(leng)(leng)凝成水后沿(yan)(yan)下部(bu)管(guan)(guan)路(lu)流出(chu)，耐腐蝕換熱器(qi)生產，不凝氣體同上部(bu)管(guan)(guan)路(lu)被(bei)真(zhen)空(kong)(kong)泵抽出(chu)，以保(bao)證冷(leng)(leng)(leng)凝器(qi)內一(yi)定的真(zhen)空(kong)(kong)度。例(li)（3）淋水板或篩(shai)板冷(leng)(leng)(leng)凝器(qi)，目的是增大冷(leng)(leng)(leng)水與(yu)蒸(zheng)汽(qi)的接(jie)觸面積。混合式(shi)冷(leng)(leng)(leng)凝器(qi)具有(you)結構簡單，傳熱等優(you)點，腐蝕性問題也比較容易解(jie)決。
