Method for processing impeller of immersible sewage pump

Abstract

The invention relates to a method for processing an impeller of an immersible sewage pump. A device for processing an impeller of a low immersible sewage pump is used. The device for processing the impeller of the low immersible sewage pump comprises a mounting bottom plate, a supporting column, a clamping mechanism and a polishing mechanism. The method can solve the problems that it is hard to clamp the impeller of a water pump stably and effectively and it cannot process a plurality of impellers at the same time as the shape of the impeller of the water pump is complex when it is needed to clamp the impeller by using a clamping tool manually in a process of processing the impeller of the immersible sewage pump and the operating labor of a worker is large, it is hard to polish the surfaceof a blade of the impeller stably and uniformly manually as the bending radian and the section shape of the blade of the impeller change, the work efficiency of processing the impeller of the immersible sewage pump is reduced as potential safety hazards may be caused by fragments and sharp edges generated in a polishing process and the like.

Description

technical field [0001] The invention relates to the technical field of water pump impeller processing, in particular to a processing method for submersible sewage pump impellers. Background technique [0002] The water pump impeller is made of cast iron. The blades on the water pump impeller play a major role again. The shape and size of the water pump impeller are closely related to the performance of the water pump. The semi-open and open impellers in the blade impeller are easy to cast, and easy to maintain and clean the impurities that are blocked during the transportation process. [0003] When processing the submersible sewage pump impeller, it is necessary to clean up the remaining burrs and debris on the outer surface of the impeller in time. However, the following problems often exist in the traditional submersible sewage pump impeller processing process: a. During the process of impeller processing, the impeller to be polished is often placed on the workbench manu...

Problems solved by technology

[0003] When processing the submersible sewage pump impeller, it is necessary to clean up the remaining burrs and debris on the outer surface of the impeller in time. However, the following problems often exist in the traditional submersible sewage pump impeller processing process: a. During the process of impeller processing, the impeller to be polished is often placed on the workbench manually, and then clamped with a clamping tool. During this period, due to the complex shape of the pump impeller, it is difficult to stabilize and effectively clamping operation, and it is impossible to process multiple impellers at the same time. The labor intensity of manual work is high, which reduces the work efficiency of processing work. Due to the continuous changes in the curvature and cross-sectional shape of the impeller blades, it is difficult to perform a stable and uniform grinding operation on the surface of the impeller blades manually. Usually, the number of impellers that need to be processed is large, and different workers may have different final results due to different work experience. The effect of processing and grinding is different, and the debris and sharp edges generated during the grinding process may cause safety hazards and reduce the working efficiency of submersible sewage pump impeller processing operations
