优质的冷冻润滑油是很纯的,颜色淡黄或为无色透明的液体 

    在压缩机中使用过一段时间的冷冻润滑油颜色会逐渐变深,透明度也会随之逐渐变差,造成变质,变质的冷冻润滑油,其冷却和润滑效果变得很差,在压缩机运转过程中会生成碳化物,很容易造成制冷系统的脏堵 

  (1)判断冷冻润滑油是否变质的方法 

    1)滴纸法。取一张干净的白纸,将压缩机壳中的冷冻油取出一点,滴在白纸上,过一 会儿观察白纸上油滴的颜色,如果油滴颜色很浅而且分布比较均匀,说明冷冻油质量较好,可以继续使用:如果发现白纸上有深色的圆点或圆环,则说明冷冻润滑油已变质或所含杂质过多,应考虑更换 

    2)对比法。取没有使用过的冷冻润滑油若干,倒入干净的玻璃试管或量筒内静置一段时间后,作为标准试样。再将需判断的冷冻润滑油从压缩机中取出一点,也倒人同样的另一个容器中,用眼睛观察比较。若从压缩机中取出的冷冻润滑油的颜色、透明度与标准冷冻润滑油的颜色、透明度差不多,说明没有变质;若从压缩机中取出的冷冻润滑油与标准冷冻润滑油相比有较明显的区别,变成橘红或红褐色的混蚀状态,说明冷冻润滑油已变质,不能继续使用,应更换冷冻润滑油
