換熱(re)器維修(xiu)要點如(ru)下：1.清洗。如(ru)果(guo)傳熱(re)效(xiao)率降低，可(ke)能是(shi)由于污垢沉積(ji)所致。此時需要進(jin)(jin)行拆(chai)卸和內部清潔來除去積(ji)聚的雜質(zhi)、油脂等物質(zhi)。2.檢查密封面(mian)是(shi)否損傷(shang)。若存在損壞，天津板式換熱(re)器清洗方案，應(ying)及時更(geng)換新的密封材料或對(dui)表面(mian)進(jin)(jin)行修(xiu)復以滿足強度(du)要求。3.解(jie)決腐(fu)蝕(shi)問題(ti)。對(dui)于由化(hua)學(xue)藥劑引起的損害必須解(jie)決，可(ke)以采取除銹劑等方式進(jin)(jin)行處理(li)，然(ran)后重新涂覆防腐(fu)層(ceng)以防止再次發生。另外需要檢查材質(zhi)選型是(shi)否正確，是(shi)否有抵(di)御可(ke)能遇到的化(hua)學(xue)侵(qin)蝕(shi)的能力。

板換維修(xiu)注意(yi)事(shi)(shi)項如(ru)下：*拆卸前仔細(xi)閱讀并(bing)理(li)解技術說明(ming)書，天津板式換熱器清(qing)洗服務(wu)，確保了(le)解安全操(cao)作步驟。先清(qing)潔設備表面(mian)和更換的(de)零件部(bu)分（特(te)別是(shi)墊片）。拆裝難度較大的(de)部(bu)件需要特(te)殊的(de)工具或者技術人員(yuan)在場進(jin)行作業處理(li)。另外一定要保護(hu)好各(ge)密封(feng)面(mian)不(bu)受(shou)損傷(shang)，在必要時(shi)增加臨時(shi)遮(zhe)擋物(wu)避免(mian)有異物(wu)刮傷(shang)或磕碰現(xian)象發生(sheng)(sheng)；同時(shi)注意(yi)不(bu)要讓雜質損壞閥芯等重(zhong)要部(bu)位。如(ru)果(guo)涉及到高溫蒸汽的(de)話要特(te)別留意(yi)以(yi)(yi)免(mian)被傷(shang)手部(bu)造成(cheng)不(bu)必要的(de)事(shi)(shi)故。請保持工作區域整潔有序(xu)防止后續清(qing)理(li)不(bu)便(bian)的(de)問題出現(xian)。*在安裝過程中(zhong)嚴禁用(yong)力過猛導致元(yuan)件再次受(shou)損的(de)現(xian)象產生(sheng)(sheng);在進(jin)行檢修(xiu)時(shi)必須將所(suo)需電源斷開(kai)(kai)禁止帶電作業以(yi)(yi)防意(yi)外觸電事(shi)(shi)故的(de)發生(sheng)(sheng)。除此之外還(huan)應注意(yi)檢查所(suo)使(shi)用(yong)的(de)配(pei)件是(shi)否(fou)齊(qi)全、完(wan)好無損以(yi)(yi)確保修(xiu)理(li)工作的(de)順(shun)利進(jin)行.當完(wan)成(cheng)所(suo)有修(xiu)復工序(xu)后應詳細(xi)核對各(ge)種參數的(de)設置及管道閥門(men)的(de)位置確認無誤后方(fang)可離開(kai)(kai)現(xian)場以(yi)(yi)保障其他人員(yuan)不(bu)會因誤按開(kai)(kai)關而引發不(bu)必要的(de)故障問題.

換(huan)(huan)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)是(shi)工(gong)業生產中(zhong)常見(jian)的維(wei)護工(gong)作，其(qi)目(mu)的是(shi)去(qu)除(chu)換(huan)(huan)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)內(nei)(nei)部的污垢(gou)和(he)沉(chen)(chen)積(ji)物，以提高換(huan)(huan)熱(re)(re)(re)(re)(re)效(xiao)(xiao)率(lv)和(he)延長(chang)設(she)(she)備(bei)壽(shou)命(ming)。以下是(shi)一些換(huan)(huan)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)的小知識：1.清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)前應(ying)(ying)先關閉(bi)換(huan)(huan)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)進出(chu)口閥門，天(tian)津板式換(huan)(huan)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)步(bu)驟，然后(hou)將換(huan)(huan)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)內(nei)(nei)部的介質排空。2.清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)方(fang)法有化(hua)學清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)和(he)機(ji)械清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)兩種(zhong)。化(hua)學清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)是(shi)通過添加化(hua)學清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)劑，天(tian)津板式換(huan)(huan)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)，使污垢(gou)和(he)沉(chen)(chen)積(ji)物溶(rong)解并(bing)排出(chu)。機(ji)械清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)是(shi)通過物理(li)手(shou)段，如高壓水(shui)(shui)射流(liu)、超聲波等，將污垢(gou)和(he)沉(chen)(chen)積(ji)物清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)除(chu)。3.清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)過程中(zhong)應(ying)(ying)注(zhu)意防止清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)劑和(he)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)水(shui)(shui)對(dui)設(she)(she)備(bei)和(he)人體的傷害。清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)劑應(ying)(ying)選(xuan)擇無(wu)腐蝕性(xing)、無(wu)毒、無(wu)刺(ci)激性(xing)的產品。4.清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)后(hou)應(ying)(ying)將換(huan)(huan)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)內(nei)(nei)部的清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)劑和(he)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)水(shui)(shui)排空，并(bing)進行(xing)干燥處理(li)。5.換(huan)(huan)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)的頻率(lv)應(ying)(ying)根據(ju)設(she)(she)備(bei)的使用(yong)情(qing)況和(he)污垢(gou)的沉(chen)(chen)積(ji)情(qing)況來確(que)定(ding)，一般建議每年(nian)進行(xing)一次清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)。6.換(huan)(huan)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)不僅可以提高換(huan)(huan)熱(re)(re)(re)(re)(re)效(xiao)(xiao)率(lv)，還可以延長(chang)設(she)(she)備(bei)壽(shou)命(ming)，降低維(wei)護成本。因此，定(ding)期(qi)進行(xing)換(huan)(huan)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)是(shi)非常必要(yao)的。
