Problems solved by technology

[0002] Most of the existing fish farming pumps are volumetric pumps with small volume, and the existing fish farming pumps can only transport air, but cannot transport solids. For large-scale fish farming, more pumps of this type are needed to meet the requirements.
When the existing fish farming pump is used in the fish farming industry, it cannot realize gas-liquid-solid or gas-liquid mixed transportation, but can only transport air, so it is not a mixed transportation pump, and the flow rate and lift cannot meet the needs

Embodiment Construction

[0031] The present invention is specifically described below through the examples, the examples are only used to further illustrate the present invention, and cannot be interpreted as limiting the protection scope of the present invention, some non-essential improvements made by those skilled in the art according to the contents of the present invention And adjustments also belong to the protection scope of the present invention.

[0032] In conjunction with the accompanying drawings.

[0033] As shown in the figure, the mixed pump impeller structure used in fish farming, the mixed pump includes at least one set of compression stages composed of a moving impeller and a stationary impeller, each moving impeller consists of a moving impeller hub 1 and a moving impeller blade 2. Each stationary impeller is composed of the stationary impeller hub 4 and the stationary impeller blade 3. The diameter at both ends of each compression stage in the axial direction is smaller than the mi...

Abstract

The invention discloses a multiphase pump impeller structure for fish farming industry. The multiphase pump impeller structure comprises at leas one group of compression stage, the axial diameter of each compression stage is of a gradually varied structure and smoothly transited, the diameter of a movable impeller hub inlet end is one third of that of a movable impeller hub outlet end, the diameter of a fixed impeller hub inlet end is one third of that of a fixed impeller hub outlet end, each movable impeller is provided with 2 groups of movable impeller blades, each blade wrap angle is equalto 195 degrees, a fixed impeller is provided with five groups of fixed impeller blades, fixed impeller blade outlet setting angle is equal to 90 degrees, the fixed impeller blades are uniformly arranged along a peripheral direction, a movable impeller blade molded line is arc, a fixed impeller blade molded line is in an shape of an S, a fixed impeller blade inlet direction is as sane as a movableimpeller blade outlet direction, and the length of an inlet section of each fixed impeller blade is one third of that of an integrated blade. According to the structure, fishes, fish food, oxygen andthe like can be conveyed in a mixed manner, flow is increased, and efficiency and heads are improved as compared with a past fish farming pump.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of conveying pumps, in particular to the design and manufacture technology of impellers of mixed transport pumps, in particular to an impeller structure of mixed transport pumps used in fish farming. Background technique [0002] Most of the existing fish farming pumps are volumetric pumps with small volume, and the existing fish farming pumps can only transport air, but cannot transport solids. For large-scale fish farming, more pumps of this type are needed to meet the requirements. When the existing fish farming pump is used in the fish farming industry, it cannot realize gas-liquid-solid or gas-liquid mixed transportation, but can only transport air, so it does not belong to the mixed transportation pump, and the flow rate and lift cannot meet the needs. Contents of the invention [0003] According to the deficiencies of the prior art, the invention discloses a mixed transport...
