     温度冲击试验箱制冷机组排污和检漏的操作步骤如下:

  1、将减压阀接在氮气瓶上,用氮气管将氮气瓶减压阀与系统加氨阀门连接起来;

  2、打开系统中除连通大气的阀门以外的所有阀门;

  3、打开加氨阀门和氮气阀,向系统充氮气至低压部分试验压力;

  4、关闭加氨阀门和氮气阀,用毛刷沾肥皂水或洗洁精对所有焊口、管接头、法兰、阀门等连接、密封部位涂抹,进行检漏;

  5、找出漏点,标上记号,找出一批泄漏点后,温度冲击试验箱试验室操作人员位于排污操作安全位置拧开低压循环贮液器(或气液分离器)下部的螺塞,排污并放出氮气;

  6、补漏,拧上低压循环贮液器(或气液分离器)的螺塞,重新充入氮气,操作人员位于排污操作安全位置拧开中间冷却器下部的螺塞,排污并放出氮气;

  7、重复上两步操作,直至无漏点;

  8、关闭低压循环贮液器(或气液分离器)进液阀和放油阀,关闭排液桶出液阀和放油阀,压缩机吸气阀和放油阀,向系统充氮气至高压部分试验压力;

  9、在对温度冲击试验箱高压部分检漏,找出漏点,标上记号,找出一批泄漏点后,操作人员位于排污操作安全位置拧开排液桶下部的螺塞,排污并放出氮气;

  10、补漏,拧上排液桶的螺塞,重新充入氮气,温度冲击试验箱操作人员位于排污操作安全位置拧开高压贮液器下部的螺塞,排污并放出氮气;

  11、重复上两步操作,直至无漏点。
