description: Centrifugal air compressors are widely used in many industries. They perform both General tasks â supply of the enterprise with compressed industrial air for internal needs, and specific
â supply of compressed air for various technological processes (production of ammonia, air separation, blast-furnace blowing). Over the time, the wear Assembly in connection with long-term operation, the increase of the air leak, is not provided with the passport settings, and indicators do not meet modern standards of energy efficiency. In parallel with this there is often a need to change the parameters of this type machines: performance, outlet pressure, etc. In this case, one of the solutions to the above problems is the modernization of the compressor. In 2017, NPF âENTEKHMASHâ successfully upgraded the compressor type K500-61-1 and three compressors type K1500-62-2. Both types of machines work as a part of the air separation unit in the chemical and metallurgical industries. The task of modernization was significant increase in compressor capacity by 12% while maintaining the regular buildings. An urgent problem in the modernization was the problem of designing the compressor first stage, which determines the capacity of the compressor. The solution was to use computational gas dynamics methods with simultaneous design development that went beyond the classical approach to the design of impellers. As a result of the work, the declared results were achieved, increased productivity and energy efficiency of the units.
