Technical Field

The invention relates to a method for processing a narrow-runner pump body, and belongs to the field of centrifugal pump processing.

Background

At present, no matter a narrow-runner pump body of a centrifugal pump is subjected to sand casting or wax mold precision casting, the flow channel of the pump body is too small, the pump body is difficult to polish and clean after casting, the roughness is low due to sand sticking on the surface, and the qualified rate of castings is low; the hydraulic performance of the pump is not ideal enough, the efficiency is low and the like.

Disclosure of Invention

The invention aims to solve the technical problems in the production process of a narrow-flow-channel pump body of a centrifugal pump, and provides a narrow-flow-channel pump body processing method.

The purpose of the invention is realized by the following technical scheme:

according to the processing method of the narrow-flow-channel pump body, the pump body structure is designed in a split mode, each split piece is processed independently, and finally each split piece is welded and fixed to form the whole pump structure.

The components of a whole that can function independently after pump body structure components of a whole that can function independently design include: the pump body hydraulic component, an inlet pipeline and flange, an outlet pipeline, an outlet flange and anchor feet.

The individual processing of each split part is realized by forging and then machining metal materials.

Advantageous effects

The pump body processing method can quickly and accurately realize the production and the manufacture of the pump body, improve the processing precision and the hydraulic efficiency of the pump body, and has high production efficiency and low cost.
