Abstract
The invention relates to processing technology for an impeller, in particular to the processing technology capable of producing and manufacturing double-blade enclosed impellers on a large scale. Theprocessing technology can greatly reduce the actual weight of the impellers, and can save 0.5KG of stainless steel material for each impeller to effectively save product cost. Only a shaft sleeve is required to be processed by a lathe, and the whole impeller is not required to be processed by the lathe any more, so the processing cost is greatly saved; the blade adopts a punching structure, so thecurve of the blade is ensured to accord with the design requirement, the thickness of the blade is thinned, and channels are more smooth than those of a cast impeller. Therefore, the impeller with the structure has better balance than the cast impeller, and has more remarkable stability in the operating process; and the pump performance and mechanical efficiency are improved greatly.
