Description

Impeller structure of water pump

Technical Field

The utility model relates to the technical field of water pump devices, in particular to an impeller structure of a water pump.

Background

Water pumps are machines that deliver or pressurize a liquid. It transfers the mechanical energy of prime mover or other external energy to liquid to increase the energy of liquid, and is mainly used to transfer liquid including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal. The water pumps can be classified into a displacement pump, a vane pump and the like according to different working principles. The displacement pump transfers energy by using the change of the volume when the displacement pump works, the vane pump transfers energy by using the interaction of a rotary vane and water, and the vane pump is of a centrifugal pump, an axial flow pump, a mixed flow pump and the like.

The impeller of the traditional centrifugal pump mainly has four forms, namely a closed type impeller, a front half-open type impeller, a rear half-open type impeller and an open type impeller, wherein the closed type impeller consists of blades, a front cover plate and a rear cover plate. The efficiency of a shrouded impeller is high and is most used in centrifugal pumps. The closed impeller is suitable for conveying clean liquid such as clear water, solution and the like which has low viscosity and does not contain particles, but is of an integral structure, the internal structure of the closed impeller is complex, and great difficulty is brought to manufacturing.
