Specific Fluid Pumps TRIZ Cases

Cutting edges on impeller blades shred fibrous admixtures to prevent clogging and maintain pump reliability.

Threaded adjusting screws move a seal member axially to set impeller clearance, reducing abrasive wear and slurry recirculation without pump disassembly.

Axial flow impeller design with segmented inlet channels homogenizes gas-liquid mixtures to eliminate gas lock risks in high-volume electric submersible pumps.

Angled wiping finger removes solids from impeller leading edges, reducing jamming and maintaining pump efficiency.

Impeller guide surfaces direct foreign matter to the outer periphery, eliminating entanglement risks from dedicated flow straighteners.

Integrated metering prevents premature gelation and component segregation during injection into soil layers.

Segmenting magnetic interactions into independent torque and axial force sets resolves the contradiction between high power output and radial rigidity limits.

A flow straightener apparatus subdivides fluid streams into channels using radially extending pins and tapered vanes.

Anti-swirl ribs on centrifugal pump diffuser walls redirect sand particles away from erosion-prone surfaces while minimizing fluid friction drag.

A non-positive displacement pump moves viscous cementitious materials using a reciprocating piston mechanism.

A volute pump casing groove channels fibrous substances away from the tongue portion using centrifugal force.

Curved front shroud and back shroud nose geometry smooths slurry flow into the centrifugal pump impeller inlet, reducing turbulence-driven particle impact wear.

Cyclone chamber applies extreme vortical forces to delaminate complex waste, resolving the trade-off between separation completeness and processing efficiency.

Recessed areas on the cutting disc create axial clearance that prevents floating matter from lodging between blades, maintaining shaft reliability.
