The stability of the typical performance of Taikang compressor

The stability of the typical performance of Taikang compressor Many people know the performance of Taikang compressors, but nothing more than the typical characteristics, such as pressure ratio, efficiency, mass flow and additional energy. But many people do not know that Taikang compressor has another more important feature, that is stability. Why is the stability of Taikang compressor so important? This is related to the disturbed compressor response of the compressor running from a stable operating point. 　　How to judge whether the performance of Taikang compressor is stable? There is a relatively simple method as follows: If the disturbance is transient and the system returns to the original working balance point, then the performance is considered stable. In addition, if the disturbance is instantaneous and the system returns to the original working balance point, the performance is considered stable. 　　An example of the above judgment method is to disturb the steady-state matching between the compressor and the driving turbine through the instantaneous change of the mass flow. If you don’t believe it, you can try it. In addition, there are other ways to judge, for example, if the disturbance is an intentional change in the operating point, and stable operation can be established under the new mass flow rate, then the performance is considered stable. At the operating point, due to the change of the power plant of the exhaust engine, this example proves the above judgment principle. 　　 If steady-state operation is not possible, then performance is unstable. An example of this is the reduction in mass flow that drives the compressor into a surge state. 　　In summary, not only Taikang compressors, but also all compressors have two performance-related stability: ① one of them relates to operational stability; ② the other relates to aerodynamic stability. 　　Operational stability is related to the performance specifications of the matching compressors such as flow devices such as throttle valves, turbines or nozzles. Aerodynamic stability involves the limitation of steady-state operation due to stall and surge. I hope this article is helpful to everyone! If you have any questions, please contact us!
