Abstract

The invention provides a high-technology ceramic pump body used for a centrifugal pump and a manufacturing method thereof. The high-technology ceramic pump body is mainly composed of a ceramic lining and a metal shell, wherein the ceramic lining is formed by combining two semicircular ceramic pieces and is provided with a feeding inlet and a discharging outlet; the metal shell is also composed of two semicircular metal pieces, the structure of the metal shell is matched with ceramic, and the ceramic and metal are bonded with high-temperature glue; and two semicircular parts are connected through bolts, the connection surface is subjected to flexible sealing, and the integrated pump body is formed. The manufacturing method of the high-technology ceramic pump body comprises the steps of ceramic lining manufacturing, ceramic-metal assembly assembling and forming machining. Compared with existing stainless steel and macromolecular pump bodies, the ceramic pump body can simultaneously meet the requirements for corrosion resistance, abrasion resistance, high-temperature resistance, good sealing performance, safety and reliability, and the life of the pump shell is prolonged by 5-10 times. Compared with pump shells inlaid with ceramic blocks, the ceramic of the pump shell of the high-technology ceramic pump body is not disengaged, leakage does not occur, and the reliability is improved.

Description

technical field [0001] The invention relates to a pump body of a centrifugal pump used in fields such as electric power, metallurgy, coal, building materials, and mines. The pump body is particularly suitable for corrosion, wear, and high-temperature working conditions, and is specifically a high-tech ceramic pump body for pumps. and methods of manufacture thereof. Background technique [0002] Centrifugal pumps are widely used in electric power, metallurgy, coal, building materials and other industries to transport slurry containing solid particles. Such as hydraulic ash removal in thermal power plants, slurry transportation in metallurgical beneficiation plants, coal slurry and heavy medium transportation in coal washing plants, etc., due to the increasingly high level of in-depth and fine processing in these industries, the corrosiveness of the transportation medium, the wear of particles, and the temperature of the medium are all important. It's getting harsher. Tradit...
