Flow passage component of high-temperature high-pressure coal chemical industry

Abstract

The invention relates to a flow passage component of a pump, in particular to a flow passage component of a high-temperature high-pressure coal chemical industry, belonging to the fluid machinery field. The flow passage component of the high-temperature high-pressure coal chemical industry comprises an impeller, a guide vane and a scaleboard; a female end of the scaleboard is located with a male end of an excircle surface of a large mouth end at right side of the guide vane in a matching way, a fastening screw penetrates through a cylindrical through hole to lead the guide vane and the scaleboard to be fixed on a pump cover, the impeller is arranged on a pump shaft and is arranged between the guide vane and the scaleboard. In the invention, the guide vane and the scaleboard are arranged ina pump body, the guide vane is used for protecting the pump body to reduce erosion wear of medium to the pump body, and the scaleboard can protect the pump cover to reduce abrasion of the medium to the pump cover. The flow passage component aims at overcoming the problems that a bearing pump body and the pump cover of the existing slurry pump are seriously wore at a circulating work station of aslurry tank, and the service life is short, thereby developing a new flow passage component of the high-temperature high-pressure coal chemical industry, improving the service life of the pump and reducing the maintenance cost of the pump.

Description

technical field [0001] The invention relates to a structure of a flow-passing part of a pump, in particular to a flow-passing part of a high-temperature and high-pressure coal chemical slurry pump, which belongs to the field of fluid machinery. Background technique [0002] Coal gasification is the leading and key technology in the development of coal chemical industry. In theory, any organic compound can be synthesized or extended through synthesis gas. After coal is gasified into synthesis gas, the synthesis gas can be used for civil use, heating, power generation or chemical production. [0003] In the domestic coal chemical industry, the pressurized gasification technology represented by TEXACO (Texaco), SHELL and GSP technology is widely used in the coal gasification process equipment. The core equipment in the pressurized gasification slag removal system; its stability directly affects the safe operation of the entire device, because the media in the above stations al...
