Guide blade adjustment device and compressor

Abstract

The invention discloses a guide blade adjustment device and a compressor. The guide blade adjustment device comprises a base, guide blades rotationally arranged on the base, a driving ring rotationally arranged on the base in a sleeving manner, first connecting pieces capable of rotating with the guide blades synchronously, and second connecting pieces fixedly connected with the first connecting pieces, wherein the first connecting pieces are movably arranged at the guide blades along the rotating axis directions of the guide blades; one second connecting piece is connected with the driving ring through a universal connecting piece; and the driving ring is movably arranged at the base along the axial direction of the base. The guide blade adjustment device simply adopts one universal connecting piece. Compared with a guide blade adjustment device adopting two universal connecting pieces in the prior art, the probability of failures such as sticking and negative rotation of the guide blades is reduced effectively, and the operating reliability of the compressor is improved; in addition, the spare parts are reduced effectively, the structure is simplified, and the processing difficulty, the assembly difficulty and the cost are reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a guide vane adjusting device and a compressor. Background technique [0002] The compressor adopts a guide vane adjusting device to regulate the load. Specifically, the guide vane adjusting device adopts a manner of rotating multiple guide vanes to adjust the suction flow of the compressor, thereby adjusting the load of the compressor. Such as figure 1 As shown, the guide vane adjustment device mainly includes: a base 13 with an inner cavity, a plurality of guide vanes 11 arranged in the inner cavity, and a drive ring 17 rotatably sheathed on the base 13; wherein, the guide vanes 11 pass through the guide vanes The bearing 12 is rotatably arranged on the base 13. Among the plurality of guide vanes 11, one guide vane 11 is a driving guide vane, and the other guide vanes 11 are driven guide vanes. The driving guide vanes drive the driving ring 17 to rotate, and the driving ri...
