Abstract

The invention discloses a method for machining a stainless steel sewage pump impeller. According to the machining technology, the method includes the following steps that step1, impeller blades, an upper cover plate and a lower cover plate are formed in a punching mode, and integral forming between the impeller blades, the upper cover plate and the lower cover plate is performed through the combination of a hydraulic machine and a punching die; step2, impeller welding: the impeller blades, the upper cover plate and the lower cover plate are welded through a welding machine, wherein the impeller blades, the upper cover plate and the lower cover plate are formed in the punching mode; step3, acid pickling and passivation are performed on the welded impeller; step4, the passivated impeller is washed through a washing machine; step5, air drying is performed on the impeller. The method has the advantages that the punching assembly and welding forming are adopted, so that the method is high in product quality, good in uniformity, short in manufacturing period, few in machining process, high in machining efficiency, free of pollution in the production process, high in operation efficiency of a water pump, high in corrosion resistant capacity and long in service life and saves consumable items.

Description

technical field

[0001] The invention relates to an impeller of a sewage sewage pump in the field of water supply and drainage, in particular to a one-time stamping forming process of the stainless steel sewage sewage pump impeller. Background technique

[0002] Sewage sewage pump is used to transport raw sewage, rainwater, feces, or liquid containing solids such as fibers, paper scraps, and fruits. Usually, the temperature of the transported medium is not higher than 80°C. It is an indispensable urban sewage discharge device now. The impeller is to convert the power of the motor to the power of the liquid or medium in the pump body, so that the liquid or medium can be transported from the pump body to the pipeline or where it is needed. Therefore, the quality of the important parts of the impeller sewage pump directly affects Affect the service life and working efficiency of the sewage pump.

[0003] At present, the impellers of sewage pumps on the market are all formed by ...
