Wearable Corrosion Resistance 95% 99% Al2O3 Alumina zirconia Ceramic Impeller
Alumina ceramic impeller comprises: impeller body, impeller body is provided with a flow port, impeller body is provided with a limited position ring groove in the middle of the upper surface, limit ring groove is provided with a fixed hole in the middle, limit ring groove in the bottom surface is provided with a rough surface, the utility model has the following advantages: through the positioning slot in the limit ring groove between the connecting rod and the impeller body mutually fixed, through The rough surface is convenient to strengthen the friction between the limit ring groove and the connecting rod, and strengthen the bite force between the connecting rod and the impeller body; The friction between the connecting rod and the impeller body is avoided through the protection layer of the inner side wall of the fixed hole; The adsorption cotton layer is convenient for the adsorption of water in the air flow, avoid the flow port inner wall contaminated with water, causing corrosion to the impeller body; The guide groove is convenient to guide the air flow, prevent the air flow in the flow mouth impact the side wall, but also avoid the air flow impact to make the impeller body vibration.Contact us
