Centrifugal compressor basic level testing device capable of being adjusted in combined mode

Abstract

The invention provides a centrifugal compressor basic level testing device capable of being adjusted in a combined mode. An inlet guide vane bracket is installed on the open side of a basic level testing volute, an inlet fluid director is installed in the inlet guide vane bracket, a plurality of inlet guide vanes are installed in the inlet guide vane bracket in the radial direction, and the inletguide vanes are driven and adjusted by an inlet guide vane adjusting mechanism; a diffuser guide vane bracket is installed in the basic level testing volute, a plurality of diffuser guide vanes are installed on the diffuser guide vane bracket, and the diffuser guide vanes are driven and adjusted through a diffuser guide vane adjusting mechanism. According to the centrifugal compressor basic leveltesting device capable of being adjusted in a combined mode, the inlet guide vane adjusting mechanism and the diffuser guide vane adjusting mechanism are combined, combined adjustment of the inlet guide vanes and the diffuser guide vanes is achieved, variable-speed adjustment can be conducted according to needs, and better equipment guarantee is provided for basic-level testing. The device can meet various basic-level test functions, is simple and accurate in operation, and saves the manufacturing cost and test cost of a test piece.

Description

technical field [0001] The invention belongs to the field of centrifugal compressors, relates to a basic stage, in particular to a basic stage testing device of a centrifugal compressor capable of combined adjustment. Background technique [0002] Centrifugal compressors play a very important role in various fields of the national economy, and are widely used in metallurgy, petrochemical, coal chemical, natural gas transmission, refrigeration and power industries, and are called "heart" equipment. How to ensure the long-term, efficient and stable operation of centrifugal compressors is one of the core issues of common concern in compressor selection design and on-site operation. At present, most of the selection and design of centrifugal compressors are carried out according to the modeling method, and the basic stage is the source of the modeling design of the compressor, and its performance directly determines the performance and energy consumption level of the compressor ...

AI Technical Summary

Problems solved by technology

[0007] The existing basic-level test methods all have certain limitations. For example, the basic-level test method using the variable speed single adjustment method is only suitable for the performance test of the basic level without inlet guide vanes and using vaneless diffusers; adjustable The combination adjustment method of inlet guide vane and variable speed is only applicable to the performance test of the basic level of vaneless diffuser; the combination adjustment of adjustable vane diffuser and variable speed is only applicable to the basic level performance testing
