Problems solved by technology

[0005] The mortar pump made of wear-resistant alloy is difficult to process due to the high hardness and difficult processing of wear-resistant alloy, especially the pump cover. Due to its complex structure, there is a static ring screw hole on it, which needs to be drilled , milling, and tapping processing have brought great inconvenience to manufacturing, time-consuming, labor-intensive, material-intensive, and low production efficiency; moreover, when casting wear-resistant alloy pump cover castings, the castings are prone to thermal stress cracks and shrinkage. hole, resulting in a higher scrap rate, which makes the production cost of the product higher

Abstract

The invention relates to an abrasion-resistant alloy mortar pump cover and a manufacturing method thereof. The pump cover comprises a cover body which is of a hollow annular structure, the edge of the cover body is cocked to form an annular groove, a circular rear jaw is arranged at the inner edge of the cover body, both the cover body and the rear jaw are made of abrasion-resistant alloy, a circular connecting block is arranged at the outer edge of the rear jaw, static ring screw holes are formed in the periphery of the connecting block uniformly, and the connecting block is made of cast iron. The abrasion-resistant alloy mortar pump cover is convenient to produce and process, timesaving, laborsaving, material saving, high in production efficiency and low in cost.

Description

technical field [0001] The invention relates to a wear-resistant alloy mortar pump cover and a manufacturing method thereof. Background technique [0002] Mortar pump is a kind of mechanical equipment for conveying medium containing solid particles, which is widely used in mining, electric power, chemical industry and other fields. [0003] For mortar pumps made of ordinary materials, the static ring screw holes on the pump cover are easy to process and form, but due to the low hardness of the material, the wear resistance is poor and the service life is short. [0004] In practical applications, most mortar pumps are made of wear-resistant alloys. [0005] The mortar pump made of wear-resistant alloy is difficult to process due to the high hardness and difficult processing of wear-resistant alloy, especially the pump cover. Due to its complex structure, there is a static ring screw hole on it, which needs to be drilled , milling, and tapping processing have brought great ...
