Centrifugal compressor provided with plurality of vortex eliminating holes

The utility model discloses a centrifugal compressor provided with a plurality of vortex eliminating holes. The centrifugal compressor at least comprises a machine shell, a rotor, a balance disc, an impeller, a partition plate and an impeller balance disc sealing assembly. A balance disc and an impeller are arranged on the rotor; the impeller balance disc sealing assembly and the machine shell arecoaxially arranged, the impeller balance disc sealing assembly is arranged around the balance disc and the impeller, and a plurality of vortex eliminating holes are formed. The vortex eliminating holes are through, one side is a balance disc side, and the other side is an impeller side. According to the utility model, unstable vibration of the rotor is prevented through the vortex eliminating holes of the impeller balance disc sealing assembly. 本实用新型公开了一种设置有多个消涡孔的离心式压缩机，至少包括机壳、转子、平衡盘、叶轮、隔板、叶轮平衡盘密封组件；所述转子上设置有平衡盘、叶轮；所述叶轮平衡盘密封组件与机壳同轴线设置，围绕平衡盘和叶轮设置，设置有多个消涡孔；所述消涡孔是贯通的，一侧是平衡盘侧，一侧是叶轮侧。本实用新型通过叶轮平衡盘密封组件的消涡孔防止转子的不稳定振动。
