Traditional equipment cleaning usually adopts immersion method, which is not convenient for effective cleaning of the complex structure of the impeller, especially for the root, edge and other parts of the impeller blade. The cleaning effect is poor, and it takes a long time. At the same time, the existing cleaning equipment may cause damage to the surface of the impeller during the cleaning process, affecting the service life of the impeller. SUMMARY
