Cavitation generation and evolution process observer with adjustable parameters

The invention discloses a cavitation generation and evolution process observer with adjustable parameters. The observer mainly comprises a motor, a shaft, a shaft sleeve, an oil groove, a tray, a heater, a pressure sensor and a high-power high-speed camera. The observer is mainly used for simulating the actual working conditions of all surface texture industrial machinery and equipment with lubricating oil flowing on the surface. A sample is driven to rotate by a motor; the pressure change of the lower surface in the rotating movement process is recorded by adopting a pressure sensor; and a high-power high-speed camera is adopted for observation in an observation hole below the sample, and the occurrence and evolution process of the cavitation phenomenon at the texture in the movement process are observed. The observer has the advantages that the occurrence and evolution process of the cavitation phenomenon can be observed in a simple and visual mode, and a certain basis is provided for analyzing the hydrodyn
