Specific Fluid Pumps TRIZ Cases
- Cryogenic Pump Balance Drum for Axial Thrust Cushioning
Fluid-compression balance drums cushion startup axial thrust in cryogenic pumps, protecting shafts, bearings, and adjacent components.
- Dual-Material Monolithic Shaft for Cryogenic Magnetic Bearings
Two shaft materials balance cryogenic toughness and ferromagnetism, enabling magnetic-bearing turbo machines to operate down to 20K.
- Angled Cutting Assembly for Blower/Vacuum Chopping Safety
Angled blades and automatic tube locking improve blower/vacuum chopping while preventing exposed cutter rotation and dust on the control board.
- Filter Assembly Protrusion Layout for Foreign Substance Discharge
Opposed protrusions and periodic reverse pump flow capture and dislodge foreign substances to prevent pipe and pump blockages.
- Split Volute Structure for Coated High-Chrome Submersible Pumps
Two-piece high-chrome volute construction improves casting yield, enables full interior coating, and cuts pump wear and maintenance time.
- Rotary Feeder Vane Geometry for Polymer Agglomerate Handling
Nonlinear vane edges and agglomerate pockets break or receive polymer clumps to prevent feeder jams, lower torque demand, and sustain throughput.
- Filter Assembly With Reverse Protrusions for Foreign Substance Removal
Reverse-facing protrusions intercept debris and help pump-driven flow dislodge clogs, keeping pipes and pumps clear.
- Pump Impeller Reverse Rotation for Automatic Blockage Clearing
When an impeller stalls from debris, the controller reverses motor polarity to clear the blockage while maintaining drainage flow.
- Vacuum-Insulated Suction Container Using Boil-Off Gas Buffering
A vacuum-insulated suction container uses a boil-off gas layer and baffle structure to cut heat input and keep liquefied-gas pumping stable.
- Blower Vacuum Cutting Assembly With Start Interlock and Angled Blades
A start interlock keeps the inlet cover closed before operation, while angled segmented blades improve debris cutting and reduce blockage.
- Low-Friction Suction Liner for Centrifugal Pump Nose Gap Sealing
A low-friction polymer flange seals the pump nose gap against the impeller, cutting slurry recirculation, wear, and liner adjustment effort.
- Intravascular Pump Sheath Inlet Layout for Lower Blood Damage
A secondary sheath inlet uses suction from the driving flow to raise total blood flow while limiting direct pump shear in minimally invasive support.
- Slurry Pump Inlet Formations for Side-Liner Wear Reduction
Surface formations on a slurry pump inlet create cross-flow turbulence that clears particulates from side-liners and reduces erosive wear.
- Submersible Pump Column Door for Zero-Purge Cryogenic Handling
An enclosed pump column with an actuator-driven door enables remote submersible pump handling while preventing boil-off gas release and purge gas use.
- Double-Suction Multi-Disc Pump for Laminar Complex Fluid Handling
Winglets, angled ribs, and stacked discs create laminar flow to pump viscous, gas-entrained, and solids-laden fluids with less wear.
- Rotating Shovel Sludge Distribution to Eliminate Manual Shoveling
A motor-driven rotating shovel spreads dried sludge evenly in a container, preventing pileup and removing the need for manual redistribution.
