  日立中央空調不制冷?可能是銅管泄露造成的！下面云南日立中央空調的小編給大家闡述一下：銅管泄露是日立中央空調的致命缺陷，一旦泄露，空調的制冷劑將全部溢出，空調由于缺乏傳熱介質而使 空調器失效。

  1、制造(zao)方面的(de)原因
  我國標(biao)準規定了(le)銅管必須進行渦(wo)(wo)流探傷(shang)(shang)。這項要求(qiu)在(zai)正(zheng)規大型(xing)銅管廠是能夠充分(fen)保證的，因為探傷(shang)(shang)是通過在(zai)線檢(jian)(jian)測的。有的銅管廠則(ze)不是這樣，不經(jing)過渦(wo)(wo)流探傷(shang)(shang)或者(zhe)是用低(di)標(biao)準的渦(wo)(wo)流探傷(shang)(shang)儀抽(chou)檢(jian)(jian)，這樣銅管就存在(zai)超標(biao)的缺陷漏檢(jian)(jian)，或未檢(jian)(jian)測造成安(an)裝日立中央空調(diao)使用時空調(diao)制冷劑泄(xie)露。

  2、安(an)裝(zhuang)的問(wen)題
  在(zai)安裝云南日立中央(yang)空(kong)調的(de)過(guo)(guo)程(cheng)中要(yao)(yao)經過(guo)(guo)彎(wan)管(guan)(guan)、漲(zhang)(zhang)管(guan)(guan)、擴口、焊接等(deng)環節。在(zai)彎(wan)管(guan)(guan)的(de)過(guo)(guo)程(cheng)中由于彎(wan)曲部分要(yao)(yao)經過(guo)(guo)局部受(shou)力，造(zao)成(cheng)局部的(de)過(guo)(guo)拉伸(shen)，形成(cheng)開(kai)裂、暗(an)裂等(deng)問(wen)題，一旦充填制冷劑，往往在(zai)此處發生制冷劑泄(xie)露(lu)。銅(tong)管(guan)(guan)穿(chuan)過(guo)(guo)翅片后，要(yao)(yao)在(zai)漲(zhang)(zhang)管(guan)(guan)機上(shang)漲(zhang)(zhang)管(guan)(guan)，漲(zhang)(zhang)管(guan)(guan)的(de)過(guo)(guo)程(cheng)極(ji)易出現漲(zhang)(zhang)頭劃(hua)傷銅(tong)管(guan)(guan)，形成(cheng)穿(chuan)透(tou)傷造(zao)成(cheng)銅(tong)管(guan)(guan)泄(xie)露(lu)；有(you)時(shi)由于鋁箔內孔的(de)毛刺(ci)過(guo)(guo)大，在(zai)漲(zhang)(zhang)管(guan)(guan)的(de)時(shi)候毛刺(ci)刺(ci)透(tou)銅(tong)管(guan)(guan)造(zao)成(cheng)泄(xie)露(lu)。

  3、銅管(guan)本身質量(liang)問題
  云南(nan)日立中央(yang)空調銅(tong)(tong)管(guan)(guan)(guan)本身(shen)質量(liang)的(de)(de)(de)原因可以分為外(wai)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)缺陷、內(nei)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)劃傷(shang)、內(nei)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)氧(yang)化(hua)等。銅(tong)(tong)管(guan)(guan)(guan)在漲管(guan)(guan)(guan)、擴口的(de)(de)(de)冷加工變形中，表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)受拉應力(li)而伸(shen)長，當銅(tong)(tong)管(guan)(guan)(guan)外(wai)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)有深度(du)(du)傷(shang)痕時，銅(tong)(tong)管(guan)(guan)(guan)外(wai)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)承受不了表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)拉應力(li)，形成(cheng)拉斷現象，也就是我們看(kan)到的(de)(de)(de)銅(tong)(tong)管(guan)(guan)(guan)外(wai)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)開(kai)裂。銅(tong)(tong)管(guan)(guan)(guan)內(nei)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)有氧(yang)化(hua)時，在漲管(guan)(guan)(guan)時由于氧(yang)化(hua)銅(tong)(tong)管(guan)(guan)(guan)內(nei)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)的(de)(de)(de)摩擦力(li)與沒(mei)有氧(yang)化(hua)銅(tong)(tong)管(guan)(guan)(guan)內(nei)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)的(de)(de)(de)摩擦力(li)不等，造(zao)(zao)成(cheng)相同(tong)長度(du)(du)的(de)(de)(de)銅(tong)(tong)管(guan)(guan)(guan)下墩長度(du)(du)尺寸(cun)不一致(zhi)，擴口時下墩量(liang)小的(de)(de)(de)銅(tong)(tong)管(guan)(guan)(guan)伸(shen)出(chu)長度(du)(du)長，造(zao)(zao)成(cheng)擴口過大(da)而開(kai)裂。

  4、焊接方(fang)式的問題
  云(yun)南日立中央空調銅管在連(lian)接起來(lai)的(de)過程(cheng)中，需(xu)(xu)要用(yong)焊(han)(han)(han)(han)料(liao)將分(fen)歧(qi)管與銅管焊(han)(han)(han)(han)接在一起，焊(han)(han)(han)(han)接方法分(fen)為(wei)充(chong)氮焊(han)(han)(han)(han)接與不(bu)充(chong)氮焊(han)(han)(han)(han)接兩(liang)種。一般會選擇充(chong)氮焊(han)(han)(han)(han)接，充(chong)氮焊(han)(han)(han)(han)接可(ke)防止焊(han)(han)(han)(han)口產(chan)生氧(yang)化物(wu)，經過長期的(de)制冷(leng)劑(ji)系統循環，不(bu)充(chong)氮焊(han)(han)(han)(han)接會導(dao)致焊(han)(han)(han)(han)口氧(yang)化物(wu)脫落造成(cheng)(cheng)管道臟堵，最后造成(cheng)(cheng)壓縮機的(de)損害。不(bu)但影響了制冷(leng)效果，嚴重(zhong)的(de)還需(xu)(xu)要對壓縮機進(jin)行(xing)維修或更(geng)換。

  以上四個方面就是日立中央空調銅管泄露的原因，當你家的日立中央空調不制冷時，很有可能就是銅管泄露了，此次你應該找日本人一級毛片免費完整視頻:云南日立中央空調安裝公司為你維修。
