Problems solved by technology

But not all parts will be subject to great friction, only the part with a large velocity gradient in the pipeline will be severely frictioned, and the traditional method of attaching the inner wall of the pipeline not only leads to a large internal resistance of the pipeline, but also increases energy consumption ,...

Abstract

The invention discloses a wear-resistant processing method of a U-shaped pipeline elbow. The method comprises the following steps: determining a steady-state turbulent velocity field and a velocity gradient of the U-shape pipeline elbow; solving to obtain a volume concentration of second-phase dust particles; calculating to obtain a friction force range of board surface of the U-shaped pipeline elbow; obtaining a high-medium friction force area enveloping curve and a medium-low friction force area enveloping curve of the board surface; obtaining fitted curve equations corresponding to the high-medium friction force area enveloping curve and the medium-low friction force area enveloping curve so as to a high friction force area, a medium friction force area and a low friction force area of the board surface; and adopting a high-polymer aluminum oxide ceramic plate in the high friction force area of the board surface and adopting a high-chromium wear-resistant alloy in the medium friction force area. According to the method disclosed in the invention, the grinding caused by the materials to the pipeline in the pneumatic transmission process can be effectively resisted, so that the wear resistance strengthening is carried out on different parts of the pipeline according to the grinding degree, the expensive materials are saved and the construction cost of the elbow is reduced.

Description

technical field [0001] The invention belongs to the field of industrial ventilation, and in particular relates to a wear-resistant treatment method for U-shaped pipe elbows. Background technique [0002] In the process of conveying abrasive materials such as pneumatic and pumped slurry, because the conveying medium generally has the characteristics of high hardness, fast flow rate, and large flow rate, it will continue to impact, wear, and corrode the pipe wall for a long time during the conveying process. , Fatigue the pipeline and gradually wear it out. Especially when the abrasive material (such as ash, coal powder, ore powder, tailings, cement, etc.) At local resistance components such as elbows, the collision between the material and the surrounding pipe wall is more severe, and it is the most severely ground part in the transmission and distribution system. [0003] Elbows are an indispensable part of industrial ventilation distribution systems. In order to prevent ...
