Abstract

The invention relates to the technical field of slurry pumps, and discloses a slurry pump capable of resisting acidic and high temperature environment. The slurry pump comprises a housing, a front protecting plate, an impeller and a rear protecting plate, wherein each of the housing, the front protecting plate, the impeller and the rear protecting plate comprises a ceramic layer, a silicon carbidecomposite adhering layer and a metal body; the silicon carbide composite adhering layers are positioned between the ceramic layers and the metal bodies; the volume density of the silicon carbide composite adhering layers is 2.65-2.9g / cm<3>; treatment layers are arranged on the outer surfaces of the metal bodies, and the inner walls, facing the metal bodies, of the ceramic layers; and each treatment layer comprises the following components including, by mass part, 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, 0.5-1part 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.

Description

technical field [0001] The invention relates to the technical field of slurry pumps, in particular to a slurry pump for resisting acidic and high-temperature environments and a preparation method thereof. Background technique [0002] Metal materials are basically used in the manufacture of domestic slurry pump flow parts. Because the main components of metal pumps are non-ferrous metals, the price is high, and they also corrode in strong oxidizing media containing halogen elements such as dilute sulfuric acid and chloride ions, which cannot meet the needs of working conditions and have a short service life; fluoroplastics Although engineering plastic materials such as high molecular weight polyethylene have excellent corrosion resistance, the mechanical strength of the material itself is not high, and it is generally combined with metal materials. The relatively high medium will cause the peeling of plastic and metal materials, which will also damage the pump parts, so the...
