On August 11th, the final of the 6th Yuhua District Industrial Innovation and Entrepreneurship Competition (Maker China Yuhua Sub Competition) in 2023 came to a successful conclusion. After auditioning, 19 projects were ultimately nominated for the finals. Our company participated in the 6th Yuhua District Industrial Innovation and Entrepreneurship Competition in 2023, titled "Research and Production of Wear-Resistance, Corrosion-Proof and Durable Centrifugal Pumps".

Project Introduction

The technical development of this project is organized and implemented by the company itself, with the technical department as the center and technical personnel as research team members.

The factors considered for selecting materials for water pumps include strength, corrosion, wear resistance, production and machining performance, maintenance performance, cost, etc. Commonly used pump materials include cast iron, cast steel, stainless steel, carbon structural steel, alloy steel, brass, and non-metallic materials. However, the surface hardness of most materials is not sufficient, and the material strength is not high enough, especially the shear strength is low. In terms of wear resistance and sand resistance, it also needs to be improved.

The wear-resistant and corrosion-resistant composite material obtained by the present invention has high wear resistance, excellent corrosion resistance, and appropriate elastic modulus, which is superior to metal materials such as brass and carbon steel. It can also be produced using injection molding technology and can be used to produce wear-resistant, sand resistant, and corrosion-resistant products, such as guide vane sleeves, sealing rings, shaft sleeves, and other main components.
