Title:
SLURRY PUMP CAPABLE OF RESISTING ACIDIC AND HIGH-TEMPERATURE ENVIRONMENT, AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/259343
Kind Code:
A1
Abstract:
A slurry pump capable of resisting an acidic and high-temperature environment, comprising a housing (1), a front protective plate (2), an impeller (3), and a rear protective plate (4). Each of the housing (1), the front protective plate (2), the impeller (3), and the rear protective plate (4) comprises metal bodies (a), ceramic layers (b), and silicon carbide composite adhesive layers (c) positioned therebetween; the volume density of the silicon carbide composite adhesive layer (c) is 2.65-2.9 g/cm3; the outer surfaces of the metal bodies (a) and the inner walls of the ceramic layers (b) facing the metal bodies (a) are provided with treatment layers; each treatment layer comprises the following components in parts by mass: 20-40 parts of silicon carbide powder less than 200 meshes, 60-80 parts of vinyl ester resin, 0.1-0.5 part of an accelerant, 0.5-1 part of a curing agent, 0.2-0.5 part of a defoaming agent, 0.2-0.5 part of a flatting agent, and 1-2 parts of a coupling agent. The slurry pump is applicable to different working conditions.
