Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pump accessories, and more specifically, to a high-stability centrifugal pump impeller. Background Art

[0002] Centrifugal pumps are used to move fluids by converting the power of rotation into the kinetic energy of the fluid as it flows. The rotational energy usually comes from an engine or electric motor. They are a subclass of dynamic axisymmetric work-absorbing turbines. The fluid enters the pump impeller along or near the axis of rotation and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing) from which it exits.

[0003] During the operation of a centrifugal pump, some impurities or particles are inevitably mixed into the liquid, which can easily clog the pump body and affect its service life and working stability. Utility Model Content
