江門市(shi)冰凍機(ji)(ji)在長期(qi)使用后，會因自身或外(wai)部因素而出現(xian)高壓(ya)報(bao)警、低壓(ya)報(bao)警、冷(leng)(leng)熱一體(ti)冷(leng)(leng)水機(ji)(ji)制(zhi)冷(leng)(leng)效果不佳或外(wai)觀不制(zhi)冷(leng)(leng)等(deng)缺陷。

江(jiang)門市冰凍機被冰堵怎(zen)么辦(ban)

制冷(leng)機等換(huan)(huan)熱(re)器(qi)在制作時，管(guan)(guan)板(ban)(ban)(ban)(ban)與(yu)列管(guan)(guan)的(de)(de)(de)焊接(jie)一(yi)般(ban)采用手工電弧焊，焊縫(feng)(feng)形(xing)(xing)狀存在不(bu)同程(cheng)度的(de)(de)(de)缺陷(xian)，如凹(ao)陷(xian)、氣(qi)孔(kong)、夾渣等，焊縫(feng)(feng)應(ying)力(li)的(de)(de)(de)分布也不(bu)均勻。使用時管(guan)(guan)板(ban)(ban)(ban)(ban)部分一(yi)般(ban)與(yu)工業(ye)冷(leng)卻(que)水(shui)接(jie)觸，而工業(ye)冷(leng)卻(que)水(shui)中的(de)(de)(de)雜質(zhi)(zhi)、鹽類、氣(qi)體、微生物(wu)都會(hui)(hui)(hui)構成對管(guan)(guan)板(ban)(ban)(ban)(ban)和(he)焊縫(feng)(feng)的(de)(de)(de)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)。這就是(shi)(shi)我(wo)們常(chang)說的(de)(de)(de)電化(hua)學(xue)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)。研究(jiu)表明，工業(ye)水(shui)無論是(shi)(shi)淡水(shui)還(huan)是(shi)(shi)海水(shui)，都會(hui)(hui)(hui)有各(ge)種離子和(he)溶解(jie)的(de)(de)(de)氧氣(qi)，其中氯離子和(he)氧的(de)(de)(de)濃度變化(hua)，對金(jin)屬(shu)的(de)(de)(de)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)形(xing)(xing)狀起重要作用。另外，金(jin)屬(shu)結構的(de)(de)(de)復(fu)雜程(cheng)度也會(hui)(hui)(hui)影響腐(fu)(fu)蝕(shi)(shi)(shi)(shi)形(xing)(xing)態。因此(ci)，管(guan)(guan)板(ban)(ban)(ban)(ban)與(yu)列管(guan)(guan)焊縫(feng)(feng)的(de)(de)(de)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)以孔(kong)蝕(shi)(shi)(shi)(shi)和(he)縫(feng)(feng)隙腐(fu)(fu)蝕(shi)(shi)(shi)(shi)為主(zhu)。從外觀看(kan)，管(guan)(guan)板(ban)(ban)(ban)(ban)表面會(hui)(hui)(hui)有許多(duo)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)產(chan)物(wu)和(he)積沉物(wu)，分布著大小不(bu)等的(de)(de)(de)凹(ao)坑。以海水(shui)為介(jie)質(zhi)(zhi)時，還(huan)會(hui)(hui)(hui)產(chan)生電偶腐(fu)(fu)蝕(shi)(shi)(shi)(shi)。化(hua)學(xue)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)就是(shi)(shi)介(jie)質(zhi)(zhi)的(de)(de)(de)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)，換(huan)(huan)熱(re)器(qi)管(guan)(guan)板(ban)(ban)(ban)(ban)接(jie)觸各(ge)種各(ge)樣的(de)(de)(de)化(hua)學(xue)介(jie)質(zhi)(zhi)，就會(hui)(hui)(hui)受到化(hua)學(xue)介(jie)質(zhi)(zhi)的(de)(de)(de)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)。另外，換(huan)(huan)熱(re)器(qi)管(guan)(guan)板(ban)(ban)(ban)(ban)還(huan)會(hui)(hui)(hui)與(yu)換(huan)(huan)熱(re)管(guan)(guan)之間(jian)產(chan)生一(yi)定(ding)的(de)(de)(de)雙金(jin)屬(shu)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)。一(yi)些管(guan)(guan)板(ban)(ban)(ban)(ban)還(huan)長期處于(yu)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)介(jie)質(zhi)(zhi)的(de)(de)(de)沖蝕(shi)(shi)(shi)(shi)中。尤其是(shi)(shi)固(gu)定(ding)管(guan)(guan)板(ban)(ban)(ban)(ban)換(huan)(huan)熱(re)器(qi), 還(huan)有溫差應(ying)力(li), 管(guan)(guan)板(ban)(ban)(ban)(ban)與(yu)換(huan)(huan)熱(re)管(guan)(guan)聯接(jie)處*易泄漏,導致換(huan)(huan)熱(re)器(qi)失效。

線型高精度機組

江(jiang)門(men)市冰(bing)凍(dong)機出現冰(bing)堵(du)(du)現象的原因是系統含(han)水量超過一定比例，凍(dong)結并堵(du)(du)塞膨脹閥(fa)/毛細管(guan)和(he)(he)蒸(zheng)發(fa)器(qi)入口(kou)處(chu)的細通(tong)道，使低壓(ya)(ya)變低或變為負壓(ya)(ya)，整機制冷效果(guo)差甚至不制冷，壓(ya)(ya)縮機電角(jiao)充量低，膨脹閥(fa)/毛細管(guan)有重小聲(sheng)音或完全沒有反應，蒸(zheng)發(fa)器(qi)不結霜，壓(ya)(ya)縮機出口(kou)和(he)(he)冷卻器(qi)不工(gong)作，在冰(bing)場外(wai)需要很長時間才能將種子(zi)清除并自(zi)行(xing)運輸。但(dan)是，經過一段時間的循環后，桶內會出現冰(bing)堵(du)(du)。這種冰(bing)堵(du)(du)常發(fa)生在手(shou)管(guan)出口(kou)和(he)(he)蒸(zheng)發(fa)器(qi)進口(kou)處(chu)。
