When the impeller is mechanically operated, the mechanical energy is first converted into the kinetic energy of the gas. The acquisition of kinetic energy is related to the flow of the gas, and the form of the flow is characterized by three-dimensional viscosity unsteadiness. Therefore, the unsteady flow phenomenon inside the impeller machinery for decades has been a hot spot for scholars from all over the world. The development of CNC machining technology has effectively promoted the processing of impellers, and the introduction or localization of four-axis, five-axis and even six-axis linkage machining centers has made the formation of complex blades a reality. Due to technological advances in design methods and processes, the overall efficiency of turbomachinery has increased by 10-20% over the past 20 years. In order to ensure the safe and reliable operation of the fluid machine, it is necessary to timely check the working state parameters of the fluid machine. Since the vibration signal has a lot to do with machine failure, it becomes the focus of detection. According to the change of the vibration frequency, the part where the machine may be faulty can be preliminarily judged, and the fault can be prevented from being expanded by timely repair. Fluid machinery is directly related to people's lives in various refrigeration machinery. The technological advancement of refrigeration and air conditioning compressors is the most important driving force for the development of the industry. Rotary compressors have received domestic attention since the 1970s, and their representative structures include moving piston, sliding vane and screw. In the field of household air conditioners, rolling piston compressors have been widely used, especially the introduction of foreign technology and capital in the 1980s, which promoted the development of the air conditioning compressor industry. In order to ensure the performance of high-power (motor output power 3P) rolling piston compressors, domestically developed dual-rotor rolling piston compressors have been put on the market at the end of the 20th century.
