It not only occupies a small area, but also is very convenient for installation and debugging. The basic construction is relatively simple and the on-site construction time is short. It is very popular among users. Of course, the assembled centrifugal compressor also has its shortcomings. Due to structural limitations, it can currently only reach the highest level of compression. It is not suitable when the pressure ratio of the unit is too large. Due to structural limitations, the seal size and installation method determine the temporary It cannot be used as a raw material compressor in petrochemical enterprises. 3. Key technologies of assembled compressors Assembled centrifugal compressors have many advantages, but their design and manufacturing are relatively complex. When developing this kind of compressor, not only the structure of the unit must be researched and tested, but also many key unit technologies need to be researched and developed in advance or in parallel. .High-performance model-level basic stage is the core part of the compressor and a key technology in compressor design. The performance of the basic stage directly affects the overall efficiency of the compressor. The model stage suitable for assembled compressors is mainly high pressure and small flow. In order to increase the pressure ratio, the impeller rotates at a high speed, the airflow speed is close to or even exceeds the speed of sound, and the flow is small. The friction loss in the flow channel is large and the flow situation is complex. Three-dimensional viscosity is required. Analytical technology performs simulation analysis of flow fields. This type of transonic high-pressure and small-flow model-level research is more difficult. Our company has done many years of research and development work on this semi-open high-Mach number model stage using imported, model-level and domestic aerodynamic analysis software. . .Reliable strength analysis and vibration analysis. The assembled centrifugal compressor is a high-speed rotating power mechanical equipment. At present, the speed of this compressor produced by our company has reached the highest speed near the impeller circumference, which has exceeded /. In this case, the strength check of rotating parts and the vibration analysis of the unit are particularly important. The calculation of the impeller includes the calculation of the strength of the impeller under the action of centrifugal force, the displacement of the blade when the impeller rotates at high speed, the interference between the impeller hole and the shaft, and the calculation of loosening speed, etc.
