板(ban)(ban)(ban)式(shi)換熱(re)器是工(gong)業生產中常用(yong)(yong)的設(she)(she)備(bei)(bei)，其清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)技巧對(dui)(dui)于保(bao)持設(she)(she)備(bei)(bei)的運行至(zhi)關重要(yao)。首(shou)先，需要(yao)確(que)定(ding)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)(ji)的種類和(he)濃(nong)度(du)，一般(ban)使用(yong)(yong)堿性清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)(ji)，成(cheng)(cheng)(cheng)都(dou)板(ban)(ban)(ban)式(shi)換熱(re)器清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)步驟，濃(nong)度(du)在(zai)10%左(zuo)右。其次(ci)，成(cheng)(cheng)(cheng)都(dou)板(ban)(ban)(ban)式(shi)換熱(re)器清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)維修(xiu)，清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)前需要(yao)先將設(she)(she)備(bei)(bei)內部的雜質(zhi)和(he)污垢清(qing)(qing)(qing)除干凈，可以使用(yong)(yong)高壓水或刷子進(jin)(jin)行清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)。然后，將清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)(ji)加(jia)入設(she)(she)備(bei)(bei)中，開啟設(she)(she)備(bei)(bei)進(jin)(jin)行清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)，清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)間一般(ban)在(zai)2-3小時(shi)左(zuo)右。清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)后需要(yao)將設(she)(she)備(bei)(bei)內部的清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)(ji)沖(chong)洗(xi)(xi)(xi)(xi)干凈，成(cheng)(cheng)(cheng)都(dou)板(ban)(ban)(ban)式(shi)換熱(re)器清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)服務，可以使用(yong)(yong)清(qing)(qing)(qing)水或蒸汽進(jin)(jin)行沖(chong)洗(xi)(xi)(xi)(xi)。清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)完畢后需要(yao)對(dui)(dui)設(she)(she)備(bei)(bei)進(jin)(jin)行干燥(zao)(zao)處理，可以使用(yong)(yong)熱(re)風干燥(zao)(zao)或自然風干。在(zai)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)過(guo)程中需要(yao)注意避免對(dui)(dui)設(she)(she)備(bei)(bei)造成(cheng)(cheng)(cheng)損壞(huai)，同時(shi)也(ye)要(yao)注意安全(quan)，避免清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)(ji)濺到皮(pi)膚或眼睛中。

換(huan)(huan)熱(re)器維修(xiu)工藝如(ru)下：1.準備工作(zuo)，根(gen)據檢(jian)修(xiu)任務提前準備好所需(xu)的(de)(de)工具和設備。檢(jian)查(cha)并(bing)確認(ren)故障原(yuan)因(yin)及位置是進(jin)行修(xiu)理的(de)(de)關鍵步驟之(zhi)一(yi)；2.對需(xu)要(yao)更(geng)換(huan)(huan)的(de)(de)部(bu)件或(huo)組件進(jin)行檢(jian)查(cha)、測試(shi)和分(fen)析，確保其符合要(yao)求后再安裝使用(yong);3.對于腐蝕嚴重的(de)(de)管(guan)板孔等部(bu)位應采用(yong)堆(dui)焊(han)法(fa)修(xiu)復，待焊(han)接后按正式焊(han)縫進(jin)行處理和維護；4.對于脹接在傳(chuan)熱(re)管(guan)的(de)(de)法(fa)蘭盤與殼體上(shang)密封面處漏液的(de)(de)問(wen)題，可以采取(qu)研磨的(de)(de)方法(fa)使兩圓(yuan)弧接觸，成都(dou)板式換(huan)(huan)熱(re)器清洗，以阻止(zhi)泄漏。此外還需(xu)要(yao)注(zhu)意安全問(wen)題如(ru)高空(kong)作(zuo)業、電烙鐵頭不(bu)帶線等問(wen)題；

板式(shi)換(huan)熱器(qi)維修(xiu)(xiu)要(yao)點如下：*確認故障。首先要(yao)確定(ding)是(shi)(shi)(shi)壓差(cha)大還是(shi)(shi)(shi)溫差(cha)不(bu)(bu)明顯，根據(ju)現象判斷可能(neng)出(chu)現的(de)問題(ti)點；如果(guo)是(shi)(shi)(shi)部(bu)件(jian)損壞(huai)請更換(huan)相關配件(jian)進(jin)行檢(jian)修(xiu)(xiu)。如果(guo)以上方(fang)法不(bu)(bu)能(neng)解決問題(ti)，建議咨詢靠譜人員獲取進(jin)一步幫助(zhu)。*檢(jian)查墊(dian)片是(shi)(shi)(shi)否松動或移位、密封面是(shi)(shi)(shi)否有雜物等導致漏水等問題(ti)出(chu)現。如果(guo)有需要(yao)重(zhong)新安裝固定(ding)好或者清(qing)理(li)(li)干凈才行。*如果(guo)是(shi)(shi)(shi)因為(wei)污垢堵塞了管子(zi)內部(bu)和盤管的(de)間隙，用清(qing)水清(qing)洗即可;若是(shi)(shi)(shi)腐蝕問題(ti)則需要(yao)使用化學(xue)藥劑處理(li)(li)。*在修(xiu)(xiu)理(li)(li)前測量并記錄數(shu)據(ju)工作(zuo)暫停之前將各項(xiang)數(shu)值(zhi)記清(qing)楚(chu)防(fang)止一時疏忽而造成(cheng)重(zhong)復(fu)拆卸。這樣可以有效減少不(bu)(bu)必要(yao)的(de)麻煩與損失時間消耗。
