    多歧管型冷凍干燥機出現漏氟現象,我們該如何處理?

    多(duo)歧管型(xing)冷(leng)凍(dong)(dong)干(gan)(gan)燥機(ji)應用了物理(li)原理(li),將壓(ya)縮空(kong)氣中的(de)(de)(de)水(shui)分冷(leng)凍(dong)(dong)至露點(dian)以下(xia)使之從空(kong)氣中析出。受限(xian)于水(shui)的(de)(de)(de)冰(bing)點(dian)溫(wen)度(du),實踐上(shang)來說它的(de)(de)(de)露點(dian)溫(wen)度(du)可接(jie)近(jin)于0度(du)。好的(de)(de)(de)冷(leng)凍(dong)(dong)干(gan)(gan)燥機(ji)露點(dian)溫(wen)度(du)普通在5度(du)左右(you)。直觀(guan)的(de)(de)(de)表(biao)相就(jiu)是冷(leng)媒壓(ya)力表(biao)為(wei)零。冷(leng)凍(dong)(dong)干(gan)(gan)燥機(ji)漏(lou)(lou)(lou)氟首先要(yao)找到(dao)漏(lou)(lou)(lou)點(dian),查漏(lou)(lou)(lou)點(dian)時需要(yao)耐心(xin)仔細和一定的(de)(de)(de)方式。先用目測法,翻開機(ji)器(qi)箱板察(cha)(cha)看(kan)機(ji)器(qi)內(nei)部(bu)(bu),因(yin)為(wei)制冷(leng)劑在運行時,會有(you)壓(ya)縮機(ji)潤滑油混在里面,如果(guo)氟利昂有(you)泄漏(lou)(lou)(lou)就(jiu)會把(ba)光滑油帶(dai)出來,那么仔細觀(guan)察(cha)(cha)機(ji)器(qi)內(nei)部(bu)(bu),如果(guo)有(you)片狀的(de)(de)(de)油污(wu)帶(dai),那就(jiu)很可能(neng)是漏(lou)(lou)(lou)點(dian)所在。而后檢查機(ji)器(qi)內(nei)部(bu)(bu)的(de)(de)(de)毛細銅...
