Blade protection system of water vapor compressor impeller

The utility model discloses a blade protection system of a water vapor compressor impeller, which comprises a compressor impeller body, the compressor impeller body comprises a wheel disc and a plurality of blades arranged outside the wheel disc, a protection mechanism is arranged in the wheel disc, and the protection mechanism is used for reducing the pressure when the compressor impeller body rotates. According to the water vapor compressor, through the multiple sets of through holes formed in the wheel disc, pressure caused by work of the pump body to the scroll plate when the water vapor compressor works is effectively relieved, so that damage to the blades is reduced, and the service life of the impeller body is prolonged. 本实用新型公开了水蒸气压缩机叶轮的叶片保护系统，包括压缩机叶轮本体，所述压缩机叶轮本体包括轮盘和设置于轮盘外的多个叶片，所述轮盘内设置保护机构，保护机构用于减小压缩机叶轮本体转动时的压力。在泵实用新型中，通过开设于轮盘内的多组通孔，有效缓解因为水蒸气压缩机工作时泵体的工作给涡旋盘造成的压力，以此减小叶片的损伤，提高叶轮本体的使用寿命。
