Wear-resistant ceramic impeller and manufacturing method thereof
The invention discloses a wear-resistant ceramic impeller. The wear-resistant ceramic impeller comprises a front cover plate, a rear cover plate and blades, wherein each blade comprises a pre-sinteredceramic block embedded into the front cover plate or/and the rear cover plate; embedding parts are arranged on the pre-sintered ceramic blocks; concave cavities into which the embedding parts of thepre-sintered ceramic blocks are embedded are formed in the front cover plate or/and the rear cover plate; and the outlines of the embedding parts are matched with the outlines of the concave cavities.The invention further provides a manufacturing method of the wear-resistant ceramic impeller. The wear-resistant ceramic impeller and the manufacturing method thereof belong to the technical field ofrotary power pump equipment; the wear-resistant ceramic impeller is higher in wear resistance, higher in cavitation resistance, proper in cost and easy to enlarge; the pre-sintered ceramic blocks which are high in wear resistance and smoother in surface are arranged on the working surfaces of the blades, so that the cavitation resistance of the impeller is improved, and the efficiency of a pump is improved; and the pre-sintered ceramic blocks extend into the front cover plate or the rear cover plate in the axial direction of the impeller, so that the pre-sintered ceramic blocks are favorablyfixed, and the strength of the impeller is favorably improved.
本发明公开了一种耐磨陶瓷叶轮，包括前盖板、后盖板和叶片，所述叶片包括嵌入所述前盖板或/和后盖板设置的预烧结陶瓷块；所述预烧结陶瓷块上设有嵌入部，前盖板或/和后盖板上设有与预烧结陶瓷块的嵌入部相嵌合的凹腔，所述嵌入部与凹腔两者的轮廓相适应。本发明还提供了一种耐磨陶瓷叶轮的制造方法。本发明的耐磨陶瓷叶轮及其制造方法，属于回转动力泵设备技术领域，耐磨性能更好、有较好抗汽蚀性能、成本适当、易于大型化，在叶片的工作表面设置耐磨性更好、表面更光滑的预烧结陶瓷块，有利于提高叶轮的抗汽蚀性能，提高泵的效率，预烧结陶瓷块沿叶轮的轴向伸入前盖板或后盖板内，有利于预烧结陶瓷块的固定，有利于提高叶轮强度。
