▎ 摘　　要

NOVELTY - The structure has a pump structure (3) which is provided with a pump structure inlet and a pump structure outlet. The inlet of the pump structure is connected with the outlet of the pump structure. The inlet of the pump structure is provided with a wear-resistant and corrosion-resistant mechanism (1). The interference fit between the wear-resistant and corrosion-resistant mechanism and the pump structure is provided. The wear-resistant and corrosion-resistant mechanism includes a skeleton and a wear-resistant and corrosion-resistant sleeve. The surface of the skeleton is coated with silicone rubber RTV-2 to form a wear-resistant and corrosion-resistant sleeve. The silicone rubber RTV-2 contains graphene materials. USE - Wear-resistant corrosion-resistant chemical pump inlet structure. ADVANTAGE - The base material of the wear-resistant and corrosion-resistant sleeve contains graphene with a mass ratio of 3% to 5%, which has a good wear-resistant and corrosion-resistant effect. The bonding force is stronger, after sintering. The wear-resistant and corrosion-resistant mechanism are need to be replaced under long-term wear and corrosion, without replacing the pump structure, which improves the operation efficiency and stability of the pump, thus greatly increasing the service life of the pump and reducing the maintenance cycle. The chemical pump inlet structure has a reasonable structure and convenient use. The wear-resistant and corrosion-resistant mechanism can be replaced to extend the service life of the pump and reduce maintenance costs in the future. The sharp corners of the skeleton in the wear-resistant and corrosion-resistant mechanism are rounded to improve the adhesion strength with the wear-resistant and corrosion-resistant sleeve. The frame thickness is uniform, and the shape is right-angled and double-right-angled to ensure the rigidity of the wear-resistant and corrosion-resistant mechanism. DESCRIPTION OF DRAWING(S) - The drawing shows a partial structure schematic diagram of wearable corrosion-resistant chemical pump.
