Specific Fluid Pumps TRIZ Cases
- Blood Pump Housing Aperture Edge Geometry for Hemolysis Reduction
Chamfered or rounded inner edges on blood exhaust apertures reduce shear stress concentrations, lowering hemolysis rates in blood pump assemblies.
- Cryogenic Pump Inducer with Counter-Rotating Vanes
Counter-rotating grooves capture rotational momentum from helicoid blades, minimizing NPSHR and preventing cavitation in vertical flow pumps.
- In-Tank Fuel Pump System with Series Piston and Centrifugal Stages
Series-mounted pumps share a drive shaft to generate high pressure without complex electrical controls.
- Integral PWR Central Riser Flow Distribution
Segmented downcomer annulus reduces flow resistance while maintaining steam generation capability through radial and circumferential distributors.
- Reversible Grinder Pump Cutting System
Segmented radial blades and an angled cutter plate grind solids in compact pumps, reducing torque and preventing clogging.
