Problems solved by technology

[0003] When transporting slurry particles with a diameter of 4-8 mm, the impeller needs to be designed with a larger diameter. The existing silicon carbide ceramic impeller has the problems of poor impact resistance and easy bursting under high pressure due to its high brittleness. The bonding effect between silicon ceramic materials and other materials is poor, and the service life is short

Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0024] Such as Figure 1~2 As shown, a medium-sized silicon carbide ceramic impeller for a heavy-duty slurry pump includes a silicon carbide ceramic 1 and a metal skeleton 2 embedded in the silicon carbide ceramic 1. The metal skeleton 2 is easy to process and has good mechanical properties. The metal skeleton 2 is arranged inside the silicon carbide ceramic 1, which significantly improves the overall impact resistance of the medium-sized silicon carbide ceramic impeller used...

Abstract

The invention belongs to the technical field of fluid equipment, and particularly relates to a middle-sized silicon carbide ceramic impeller for a heavy slurry pump. The middle-sized silicon carbide ceramic impeller for the heavy slurry pump comprises silicon carbide ceramic and a metallic framework inlaid inside the silicon carbide ceramic. The metallic framework comprises a hub and metal blades.The metal blades are fixedly arranged on the outer side of the hub. An assembling clearance is reserved between the metallic framework and the silicon carbide ceramic. The assembling clearance is filled with resin adhesives. The middle-sized silicon carbide ceramic impeller for the heavy slurry pump is suitable for conveying slurry particles with the diameters ranging from 4 millimeters to 8 millimeters for a long time, can be conveniently connected with or fixed to a spindle, and further has the characteristics of being good in shock resistance, suitable for being used under high pressure, long in service life and the like.

Description

technical field [0001] The invention belongs to the technical field of fluid equipment, in particular to a medium-sized silicon carbide ceramic impeller for a heavy-duty slurry pump. Background technique [0002] The heavy-duty slurry pump is suitable for the transportation of slurry containing solid particles, which is resistant to abrasion and corrosion, 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 heavy-duty slurry The core component of the pump, 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 of 4-8 mm, the impeller needs to be designed with a larger diameter. The existing silicon...
