[0002] Impeller refers to the wheel disk with moving blades, which is a component of the impulse turbine rotor, and can also refer to the general term for the wheel disk and the rotating blades installed thereon. The wear of the impeller is related to the composition, particle size, concentration, shape, impact speed, impact angle of the abrasive, the chemical composition, properties, temperature and humidity of the gas, and the unevenness of the gas flow inside the impeller accelerates the wear, which requires improving the wear resistance of the impeller; the existing impeller has certain disadvantages when used, and the wear resistance of the impeller can be improved by using materials with high hardness and good wear resistance, which not only brings difficulties to the impeller manufacturing process, but also is unreasonable from an economic point of view. When the blades are severely worn, they need to be replaced. The blades are mostly welded on the impeller shaft, which is difficult to disassemble and inconvenient to maintain. For this reason, we propose a wear-resistant impeller mechanism that is easy to maintain. Utility Model Content
