Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a compressor impeller water washing device. Background Art

[0002] The compressor impeller of a gas turbine is prone to fouling during operation, which can cause an uneven impeller surface and affect the efficiency of the compressor. These deposits may include oil, dust, salt, etc. These substances attached to the impeller will reduce the aerodynamic performance of the impeller. In order to remove scale and restore efficiency, the compressor usually needs to be washed offline. At present, the industry uses manual cleaning methods to clean the compressor impeller. Not only is the cleaning efficiency low, but the labor cost is also high.

[0003] After searching, a Chinese patent with publication number CN209238563U discloses a water washing device for a compressor impeller, which includes a base, a cleaning box and a stirring mechanism. The stirring mechanism controls the water flow for cleaning the impeller. However, the following defects still exist: although the scale on the surface of the impeller can be removed to a certain extent by immersing the impeller in the cleaning box and cleaning it with water flow, there is no water changing mechanism, which will make the cleaning water in the cleaning box gradually turbid during the cleaning process, affecting the cleaning effect. If the water is changed frequently, it will cause a waste of water resources. Utility Model Content
