鹽霧試驗箱空氣供給要求

發布日期:2022-08-22 點擊率:101

  鹽霧試驗箱適用于零部件、電子五金元件、金屬材料的防護層以及工業產品的鹽霧腐蝕試驗。鹽霧試驗箱空氣供給要求如下:

  1、進入噴霧裝置的壓縮空氣應不含任何雜質,如油、灰塵等。

  2、應采取措施使壓縮空氣的濕度和溫度達到運行條件的要求。空氣壓力應當適于產生細小、潮濕、密集的霧。

  3、為了防止鹽沉積堵塞噴霧裝置,推薦噴嘴處的空氣相對濕度至少為85%。一種可行的方法如下:讓氣流以非常小的氣泡形式通過自動維持恒定的熱水塔,水溫至少為35℃。

  4、允許的水溫隨著空氣流量的增加以及鹽霧試驗箱及其環境熱絕緣的降低而增加。

  5、水溫不應過高,以免帶入試驗箱過多水分,也不能超過規定的運行溫度。
