A preparation method of fan impeller inlaid ceramics

Abstract

Disclosed is a ventilator impeller embedment ceramic manufacturing method. Compared with metal materials, ceramic materials have the performance advantages of being high in hardness and strength, and resistant to high temperature, abrasion, corrosion and oxidation and the like. According to the traditional ceramic sticking technology, due to the fact that an adhesive loses efficacy when aged at high temperature and ceramic chips are affected by medium impact loads, the ceramic chips are likely to be disengaged, and the wear resistance of a fan is lowered. The invention provides wear-resisting ceramic embedded on the working face of a fan impeller and the manufacturing method thereof so as to solve the problems and achieve the better using effect. Special embedded ceramic blocks are obtained according to the structural design of the fan, and an embedment ceramic steel clamp is designed. By means of plug welding of the steel clamp, the ceramic blocks are embedded and stuck through an adhesive, the composite material of the wear-resisting ceramic embedded on the working face of the fan is obtained, and the technical requirements for abrasion resistance, high temperature resistance, impact resistance and disengagement prevention are met, so that the service life of the ventilator is greatly prolonged, the cost is lowered, and benefits are created.

Description

technical field [0001] The invention belongs to the field of composite wear-resistant materials, and in particular relates to a preparation method for inlaying wear-resistant ceramics on the working surface of an impeller of an industrial centrifugal fan. Background technique [0002] Industrial centrifugal fan (hereinafter referred to as fan) is a main power equipment commonly used in building materials, metallurgy, cement and other industries. Since the working medium contains a certain amount of homogeneous particles of different sizes and shapes, these fans are used in various Working in the medium airflow, the medium in the airflow will cause severe wear to the fan, and the unevenness of the wear will damage the dynamic balance of the fan rotor group, causing the fan casing to vibrate, thereby shortening the operating life of the fan. Cause the fan to run abnormally. In order to realize the efficient operation of the fan, eliminate the existing safety hazards, prolong ...
