Description
Technical Field
The utility model relates to the technical field of pumps, concretely relates to metal lining carborundum impeller.
Background
The pump has a working condition in metallurgy, chemical industry and other industries, the Cl-/content in the liquid conveyed by the pump reaches more than 10%, and the solid particle content in the liquid is more than 20%. The metal pump body (see fig. 1) is selected to be resistant to corrosion but not resistant to corrosion; if the fluoroplastic pump body is selected to be corrosion-resistant but not abrasion-resistant, the working condition is called cancer in the chemical industry. While the silicon carbide (SiC) material is corrosion-resistant and wear-resistant, and has the defect of brittleness.
The fluoroplastic impeller is formed by adopting a high-temperature thermoplastic metal die pressing process, and due to the structural complexity of the impeller and the difficult characteristic of die dismounting, the die is dismounted after the impeller is pressed conveniently, the traditional impeller is generally designed into a semi-open impeller, the shape of the impeller blade is cylindrical (two-dimensional blade), although the die is dismounted conveniently, the impeller is poor in pump performance and low in pump efficiency.
SUMMERY OF THE UTILITY MODEL
To the above problem, the present invention is directed to a metal-lined silicon carbide impeller.
In order to realize the technical purpose, the utility model discloses a scheme is:
preferably, a metal-lined silicon carbide impeller comprises an impeller body, and is characterized in that: the impeller body be provided with outer lining carborundum layer, the impeller body set up to impeller metal inner insert, the impeller body include the blade, the blade adopt the space distortion blade.
Preferably, the impeller body is a closed impeller, and the impeller body is made of fluoroplastic materials.
Preferably, the impeller body is formed by die pressing.
The utility model has the advantages that:
1. the surface of the metal impeller insert is coated with the silicon carbide layer, so that the problems of corrosion resistance and wear resistance are solved, and the strength of the impeller is ensured. The silicon carbide impeller is formed by die pressing.
2. A closed impeller is adopted, and the blades are spatially twisted blades (three-dimensional blades) and adopt an excellent hydraulic model design; the shape of the blade accords with the liquid flowing rule, the hydraulic loss is small, the pump efficiency is high, the novel impeller adopts the technological innovation, and the impeller mould is also convenient to disassemble.
