板式雙管板換熱器在使用的過程中會遇到一些故障情況，比如遇到了外漏情況，這時候我們要先分析為何會產生這樣的情況，然后在進一步分析如何處理以及下次如何避免再次發生。
1、雙管(guan)板(ban)換(huan)熱器(qi)外(wai)漏(lou)產生原因：①夾緊尺(chi)寸不(bu)到位、各(ge)(ge)處尺(chi)寸不(bu)均(jun)勻(各(ge)(ge)處尺(chi)寸偏差不(bu)應大(da)于3 mm)或(huo)(huo)夾緊螺栓(shuan)松(song)動。② 部分密(mi)(mi)(mi)(mi)封(feng)墊脫離密(mi)(mi)(mi)(mi)封(feng)槽(cao)(cao)，密(mi)(mi)(mi)(mi)封(feng)墊主密(mi)(mi)(mi)(mi)封(feng)面有(you)臟(zang)物，密(mi)(mi)(mi)(mi)封(feng)墊損壞或(huo)(huo)板(ban)式換(huan)熱器(qi)密(mi)(mi)(mi)(mi)封(feng)墊片(pian)老(lao)化。③ 板(ban)片(pian)發生變形(xing)，組(zu)裝錯位引起(qi)跑墊。④在(zai)板(ban)片(pian)密(mi)(mi)(mi)(mi)封(feng)槽(cao)(cao)部位或(huo)(huo)二道密(mi)(mi)(mi)(mi)封(feng)區域有(you)裂紋。實例：北京(jing)、青海和新疆等地的(de)多個熱力站均(jun)采用(yong)飽和蒸汽(qi)作為一次(ci)側熱源供暖(nuan)，由于蒸汽(qi)溫度較高，在(zai)設備運行初期系統不(bu)穩定的(de)情(qing)況下，橡膠密(mi)(mi)(mi)(mi)封(feng)墊在(zai)高溫下失效，引起(qi)蒸汽(qi)外(wai)漏(lou)。
2、雙管板(ban)(ban)(ban)換(huan)(huan)熱器(qi)(qi)外(wai)(wai)漏處(chu)理方法：① 在無壓(ya)狀態(tai)，按制(zhi)造廠(chang)提供的夾緊(jin)(jin)尺(chi)寸(cun)(cun)重新(xin)夾緊(jin)(jin)設備(bei)(bei)，尺(chi)寸(cun)(cun)應(ying)均勻(yun)一致，壓(ya)緊(jin)(jin)尺(chi)寸(cun)(cun)的偏(pian)差(cha)應(ying)不大(da)于±0.2N (mm)(N。為(wei)板(ban)(ban)(ban)片(pian)(pian)(pian)總(zong)數)，兩壓(ya)緊(jin)(jin)板(ban)(ban)(ban)間(jian)的平行度應(ying)保持在2 mm 以內。② 在外(wai)(wai)漏部(bu)位(wei)(wei)上(shang)做(zuo)好標記，然后(hou)換(huan)(huan)熱器(qi)(qi)解(jie)體逐一排查解(jie)決，重新(xin)裝(zhuang)(zhuang)配(pei)或更(geng)換(huan)(huan)墊片(pian)(pian)(pian)和板(ban)(ban)(ban)片(pian)(pian)(pian)。③ 將(jiang)(jiang)開(kai)換(huan)(huan)熱器(qi)(qi)解(jie)體，對板(ban)(ban)(ban)片(pian)(pian)(pian)變(bian)形部(bu)位(wei)(wei)進行修理或者更(geng)換(huan)(huan)板(ban)(ban)(ban)片(pian)(pian)(pian)。在沒有板(ban)(ban)(ban)片(pian)(pian)(pian)備(bei)(bei)件時(shi)可將(jiang)(jiang)變(bian)形部(bu)位(wei)(wei)板(ban)(ban)(ban)片(pian)(pian)(pian)暫時(shi)拆除后(hou)重新(xin)組裝(zhuang)(zhuang)使用。④ 重新(xin)組裝(zhuang)(zhuang)拆開(kai)的板(ban)(ban)(ban)片(pian)(pian)(pian)時(shi)，應(ying)清潔板(ban)(ban)(ban)面，防止污物粘(zhan)附著于墊片(pian)(pian)(pian)密封面。
相信如果遇到了一次故障問題(ti)之后，在之后使用雙管板換熱器(qi)會(hui)更加的小心謹慎，避免在發生同(tong)樣的情況啦。
