The invention discloses a compressor with an interstage guide vane. The compressor with the interstage guide vane comprises a multi-stage impeller and the inter-stage guide vane body, the inter-stageguide vane body comprises an upper-stage impeller outlet section, a bent pipe section, a backflow section and a lower-stage impeller inlet section which are sequentially connected, wherein a pluralityof first guide vanes arranged in the circumferential direction are arranged in the bent pipe section, a plurality of second guide vanes arranged in the circumferential direction are arranged in the backflow section, first front edges and first rear edges are arranged on the first guide vanes, second front edges and second rear edges are arranged on the second guide vanes, the compressor is characterized in that the first rear edges are arc-shaped bulges, the arc-shaped bulges protrude towards the downstream, the second front edges are arc-shaped recesses, the arc-shaped recesses sink towardsthe downstream, and the arc-shaped bulges and the arc-shaped recesses are consistent in direction. The interstage guide vane can reduce eddy current of the bent pipe section and reduce the pressure loss of the bent pipe section, so that the performance of the compressor is improved.
Description
technical field [0001] The invention relates to the technical field of fluid conveying machinery (multistage compressors), in particular to a compressor with interstage guide vanes. Background technique [0002] The multi-stage compressor includes multi-stage impellers and interstage guide vanes. The interstage guide vanes include the outlet section 1 of the upper impeller, the elbow section 2, the return section 3, the inlet section 4 of the lower impeller, and the inside of the elbow section 2. There are a plurality of first guide vanes 5 arranged in the circumferential direction, and a plurality of second guide vanes 6 arranged in the circumferential direction are arranged in the return section 3, and the second guide vanes 6 are located downstream of the first guide vanes 5, and the first The guide vane 5 has a first leading edge and a first trailing edge, and the second guide vane 6 has a second leading edge and a second trailing edge (such as figure 1 shown). However...
