Guide vane adjusting structure for centrifugal compressor

The invention belongs to the technical field of centrifugal compressors, and discloses a guide vane adjusting structure for a centrifugal compressor. The guide vane adjusting structure at least comprises a worm gear, a worm and a motor; the motors are used for driving the worms to rotate, and each worm is in transmission connection with each worm gear. And when the worm gears rotate, blades in theguide vane assembly are driven to rotate, and a series of problems of complex traditional structural form, high manufacturing and mounting requirements, high cost and the like are solved. 本发明属于离心压缩机技术领域，公开了一种离心压缩机用导叶调节结构。所述导叶调节结构至少包括蜗轮、蜗杆、电机；所述电机用于驱动蜗杆转动；所述蜗杆与蜗轮传动连接；当蜗轮转动时，带动导叶组件中的叶片转动，解决了传统结构形式复杂、制造和安装要求高、成本高等系列问题。
