Embodiment 1
[0014] An impeller for a wear-resistant and corrosion-resistant centrifugal pump, including blades, a disc, a front cover and a rear cover, the blades are sleeved in installation grooves on the outer periphery of the disc, and the roots of the front cover and the rear cover are fixed and installed by threads On the mounting seat on the wheel, the front cover and the rear cover are respectively covered in the middle of the two sides of the blade. The front cover and the rear cover can strengthen the blade and improve the blade. strength, so as to effectively resist the impact of large particle media in the slurry on the blades. The disc, front cover and rear cover are all made of wear-resistant alloy materials, and the blades are made of silicon carbide ceramic materials. , The ceramic blades are corrosion-resistant, and the outer surfaces of the blades, discs, front cover and rear cover are covered with a layer of corrosion-resistant coating.
