<\/a><\/p>\nThe rotors of centrifugal compressors have been successfully operated and now possess the range of the following advantages:<\/p>\n
\u2022 during design of the impellers the modern methods of blades profiling are used, providing the maximum output-input ratio;<\/p>\n
\u2022 at the stage of design engineering all the critical parts are subjected to strength analysis;<\/p>\n
\u2022 application of high-quality corrosion-resisting steel for manufacture of impellers provide their stability in aggres-sive environment and increase the operational life of the assembly;<\/p>\n
\u2022 milling blades of impellers is performed at the advanced CNC five-axis machines, providing the processing of parts with complex space geometry, high accuracy of dimensions and quality of the surface;<\/p>\n
\u2022 the welding technology of impellers \u00abthrough the slot\u00bb in the atmosphere of shielding gas allows performing high-strength corrosion resistant welding of weld-in connections, increasing overhaul period in comparison with riveted connections 7-10 times. The welding is performed by the qualified staff with corresponding tolerance and license application for the work performance;<\/p>\n
\u2022 the whole operation cycle of parts is performed at the one enterprise, providing the qualitative control of the part manufacturing;<\/p>\n
\u2022 the production centre allows shaft processing, which length is up to 3800 mm. The maximum diameter of impellers is up to 860 mm;<\/p>\n
Assembly process includes elementwise balancing of all the principal parts. The final balancing can be performed in vacuum unit at the operating rotations.<\/p>\n
Production and technological capacities of TRIZ Ltd enable to manufacture rotors for the main positions of ammonia, carbamide, weakly azotic acid and methanol production.<\/p>\n
