Detailed Description
For a better understanding of the present invention, reference is made to the following description taken in conjunction with the accompanying drawings. It is noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
Example (b):
the ceramic impeller for protecting the fixed steel component comprises a ceramic part 1, blades 2 and a connecting shaft 3, wherein the ceramic material is silicon nitride combined silicon carbide ceramic or silicon carbide ceramic, and the wear resistance of the ceramic impeller is 3-5 times that of high-chromium cast iron. The pores on the surface of the ceramic part 1 are filled with resin. The ceramic impeller is treated by soaking resin, air holes on the ceramic impeller are filled, and the impeller is improved to optimize the quality of the gear.
As shown in fig. 2, the ceramic part 1 is connected to the fixing steel member 4 by providing an epoxy resin adhesive layer therebetween. And, ceramic portion 1 one side be equipped with recess 7, fixed steel member 4 cross-section be with recess 7 assorted T type structure.
As shown in fig. 2, a ceramic protective sleeve 6 is hermetically mounted on the other side of the fixed steel member 4, and the ceramic protective sleeve 6 is made of sintered silicon nitride combined with silicon carbide ceramic or other complex-phase silicon carbide ceramic. An epoxy resin bonding layer for connecting the fixing steel member 4 and the ceramic protective sleeve 6 is arranged between the fixing steel member and the ceramic protective sleeve, and the used bonding agent can be selected according to working conditions, such as high temperature resistance, acid and alkali resistance and the like.
As shown in fig. 3, the fixed steel member 4 is provided with an annular groove 8, the annular groove 8 is internally provided with a sealing ring 9 connected with the ceramic protective sleeve 6, the sealing ring 9 is an O-shaped sealing ring, and the annular groove 8 and the sealing ring 9 can prevent the fixed steel member 4 from being separated from the ceramic protective sleeve 6.
As shown in fig. 1 and 2, the ceramic protecting sleeve 6 is not affected by the driving force, the ceramic protecting sleeve 6 and the connecting shaft 3 are connected by T-shaped threads, and the rotating direction of the blade 2 (i.e. the rotating direction of the ceramic impeller) is opposite to the T-shaped threads. In the rotation process of the ceramic impeller, the impeller and the connecting shaft 3 are always in a twisted state, so that the phenomenon that the impeller loosens and takes off wires is avoided.
