Technical Field
[0001] The utility model belongs to the technical field of impeller assembly and disassembly, and particularly relates to an impeller structure which is convenient for assembly and disassembly. Background Art
[0002] The impeller refers to the wheel disc with moving blades, which is a component of the impulse turbine rotor. It also refers to the general term for the wheel disc and the rotating blades installed on it. The impeller is a rotating body with blades that transfers energy to the liquid.
[0003] The impeller will be damaged after long-term use, and the staff will need to disassemble and repair the impeller inside the device. Since the existing devices usually fix the impeller on the shaft with several screws, it is very cumbersome for the staff to disassemble the impeller and it takes a lot of time, which reduces the staff's maintenance efficiency of the impeller. Utility Model Content
[0004] The purpose of the utility model is to provide an impeller structure that is easy to load and unload. By setting up a loading and unloading component, the staff can quickly and conveniently load and unload the impeller, which solves the problem that the existing device usually fixes the impeller on the rotating shaft by several screws, making it very cumbersome for the staff to disassemble the impeller and taking up a lot of time, thus reducing the staff's maintenance efficiency of the impeller.
