【技术实现步骤摘要】
可提高涡旋压缩机端面密封性能的机构
本技术属于电动汽车空调涡旋压缩机端面密封用具
,尤其涉及一种可提高涡旋压缩机端面密封性能的机构。
技术介绍
现在加工电动汽车涡旋空调压缩机的端面密封一般采用等高平底技术,这样的结果是接触面长,压力相同,导致功耗较高,对于电动汽车空调涡旋压缩机来讲会造成COP下降,底面平直会使高压气体引入通道缝隙小,浮动效果一般。从而会造成端面的密封性能较差,能效比较小,压缩机使用期限较短。
技术实现思路
本技术的目的在于解决以上所述的技术问题,提供一种可以提高和改善电动汽车空调涡旋压缩机的端面密封性,大大提高整机达到高的密封性的要求,提高能效比,使得压缩机的使用期限延长的可提高涡旋压缩机端面密封性能的机构,其技术方案如下:可提高涡旋压缩机端面密封性能的机构,其特征在于,涡旋压缩机上加工有曲线形密封端面,曲线形密封端面的上部设置有密封槽,密封槽的槽形为外深内浅,深度变化范围为0.03-0.1mm,密封槽的底部开设有流道槽,流道槽在引入高压气流的时候将密封件抬高压紧。优选方式为,流道槽的宽是1.5mm,深度为0.1-0.3mm。可提高涡旋压缩机端 ...
