Technical Field

[0001] The utility model relates to the technical field of mixed flow pump processing, in particular to an ultrasonic cleaning jig for a mixed flow pump impeller which is easy to transfer. Background Art

[0002] A mixed flow pump is a pump between a centrifugal pump and an axial flow pump. It mainly works by the combined action of centrifugal force and thrust generated by the rotation of the impeller. It is generally used to transport clean and contaminated media, as well as chemically neutral or corrosive media. The impeller in the mixed flow pump is an important working component inside the mixed flow pump. During the production and processing, there will be some protruding burrs on the external surface. After surface grinding and other processes, ultrasonic cleaning equipment will be used for ultrasonic cleaning in order to remove residual debris inside the impeller and ensure the smoothness of the internal mounting surface of the impeller. During ultrasonic cleaning, a jig is needed to assist in fixing and limiting the impeller.

[0003] However, when the ultrasonic cleaning jig for the mixed flow pump impeller is used to load and fix the impeller workpiece and put it into the ultrasonic cleaning tank for cleaning, the jig is generally installed directly in the ultrasonic cleaning tank, and a single set of impeller workpieces are fixed and disassembled back and forth for cleaning, or the impeller workpieces are directly thrown into the cleaning tank without using a jig. After cleaning, they need to be transferred one by one. The impeller transfer process is relatively cumbersome. The entire cleaning process is not only time-consuming and labor-intensive, but also inefficient and has shortcomings. It is not convenient for cleaning the impeller workpiece and the centralized transfer after cleaning.

[0004] Now, a new type of ultrasonic cleaning jig for mixed flow pump impeller which is easy to transfer is proposed to solve the above-mentioned shortcomings. Utility Model Content
