一种氨制冷封闭式压缩机密封方法的研究

One of the Research of the Sealing Method On the Close Type Compressor of Ammonia Refrigeration

提出了一种压缩机的压力平衡式密封结构 ,实现了对电动机定子的无压差静密封 ,可靠地保证了定子防止氨腐蚀 ,使得制造氨制冷封闭式压缩机成为可能 ,为研制制冷设备提供了新思路。

It brings forward a seal structure of pressure balance in compressor,to realize the non-pressure difference static seal of electric motor stator,which reliably ensures the stator free from the corrosion of ammonia. The manufacture of hermetic ammonia refrigeration compressor becomes possible. It supplies a new idea on developing refrigeration equipment.
