Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pumps, in particular to an impeller for a pump. Background Art

[0002] As a vital component of a centrifugal pump, the impeller undertakes the key task of converting the mechanical energy provided by the power source into the kinetic energy and pressure energy of the fluid. Its mechanical structure can be divided into three types: closed, semi-open and open according to different working environments and fluid characteristics, and can be divided into single-suction and double-suction types according to the liquid suction method.

[0003] The flow rate, head and efficiency of the pump are closely related to the shape, size and surface roughness of the impeller. In the existing technology, metal additive manufacturing technology is used to improve the structure of pump impellers. This improved manufacturing method can provide higher design flexibility and precision, thereby achieving a more optimized impeller shape and performance. Through metal additive manufacturing, the impeller manufacturing process is more efficient, and complex structures and customized designs can be easily realized.

[0004] In the prior art, when in use, since the impeller blades and the impeller frame are integrally formed, the number of impeller blades cannot be conveniently adjusted according to the needs of the working scene, which results in the user being unable to adjust the configuration of the impeller according to specific flow or pressure requirements, which can cause the pump to operate inefficiently or have unstable performance in some cases. For example, when the demand is low, if the number of impeller blades cannot be reduced to match the flow, the pump will consume additional energy in the case of excessive operation, resulting in unnecessary energy waste. Secondly, the impeller blades will gradually wear out during long-term use. When it reaches a certain level, the entire impeller needs to be replaced. Therefore, a pump impeller is proposed to solve the above problems. Utility Model Content
