Abstract

The invention belongs to the technical field of fluid equipment, and particularly relates to a large silicon carbide ceramic impeller for a heavy slag slurry pump. The large silicon carbide ceramic impeller comprises a silicon carbide ceramic and a metal framework inlaid in the silicon carbide ceramic; the metal framework comprises a front cover plate, a metal blade and a rear cover plate, the metal blade is arranged between the front cover plate and the rear cover plate in a clamped mode, an assembling gap is reserved between the metal framework and the silicon carbide ceramic, and the assembling gap is filled with resin adhesive. The large silicon carbide ceramic impeller is suitable for long-term conveying of slurry particles with the diameter larger than 8 mm, has the characteristics of being good in impact resistance, suitable for high-pressure use, long in service life of impeller and the like, and can be conveniently connected and fixed with a main shaft.

Description

technical field [0001] The invention belongs to the technical field of fluid equipment, in particular to a large silicon carbide ceramic impeller for a heavy slurry pump. Background technique [0002] The heavy-duty slurry pump is suitable for transporting the slurry containing solid particles, which is wear-resistant and corrosion-resistant, such as slurry transportation in metallurgical ore dressing plants, ash and slag transportation in power plants, coal slurry transportation and heavy medium transportation, etc. The impeller is a heavy-duty slurry pump The core component of the impeller, using silicon carbide ceramics as the surface contact material of the impeller is an important method to improve the wear resistance and corrosion resistance of the impeller, and can effectively improve the service life of the impeller. [0003] When transporting slurry particles with a diameter greater than 8mm, the diameter of the impeller is generally greater than 500mm. The existing...
