Specific Fluid Pumps TRIZ Cases
- Electric Submersible Motor Thrust Bearing Lock Ring
Interference-fit lock ring prevents bolt shear failure and maintains axial positioning stability in electric submersible motors.
- Cryogenic Pump Motor Thermal Segmentation
Thermal segmentation isolates the motor in gas phase from liquid impeller, reducing precooling time and vaporization losses.
- Volute Pump Sweep-Back Vane Curved Leading Edge
A volute pump impeller uses a curved leading edge on sweep-back vanes to guide fibrous substances into the casing groove.
- Parallel Pump Pressure Head Equalization Control
A control system measures outlet pressure heads of parallel pumps to synchronize their operation and maintain identical outputs.
- Centrifugal Pump Wear Plate Axial Distance Adjustment
External adjustment mechanism sets wear plate axial distance to eliminate complex pump disassembly and seal replacement during maintenance.
- Submersible Pump External Slicer for Solid Handling
External slicer cuts solids to prevent clogging and motor overload.
- Concrete Residue Collection Auger for Mixing Truck Chutes
Auger conveyor captures slurry aggregate from truck chutes, returning material to the mixing drum to eliminate disposal costs and environmental hazards.
- Rotary Pump Seal Housing Thermal Decoupling
A segmented seal housing uses thermal decoupling to dissipate heat from the inner component via a conductive outer part.
- Froth Pump Radial Segmentation for Air Separation
Radial segmentation separates air from frothy fluids in a collection chamber, reducing mechanical failures and increasing flow rates.
- Hybrid Axial Radial Cutter for Wastewater Solids Reduction
Segmented cutting arms with radial and axial edges reduce solid matter size, lowering energy consumption and preventing clogging in wastewater pumps.
- Axial Pump Repelling Vanes for Seal Protection
Repelling vanes on an axial pump hub use centrifugal force to eject solids from seals and bearings, preventing damage when flushing fluid fails.
- Pump Cutting Impeller Axial Counter Knife
Axial counter knives prevent shaft winding by chopping fibrous materials through scissor-like action with the cutting impeller.
- Self-Priming Pump System Vacuum Gas Transport
Vacuum pump unit transports gas along liquid delivery unit, eliminating reservoirs and reducing component complexity.
- Overflow Molten Metal Transfer Pump Flux Introduction
Rotating impeller elevates molten metal above the bath surface to introduce flux and inert gas, reducing splash and porosity during transfer.
- Submersible Pump Agitator Auger Dredging Detritus
Segmented suction path and rotating auger suspend detritus to prevent blockages in dredging operations.
- Compact Cryogenic Pump Gas Release Plate Cavitation Control
A compact cryogenic pump uses a gas release plate to vent bubbles and an inducer to raise pressure for continuous low flow operation.
- Self-cleaning Pump Recessed Notch Shearing Mechanism
Ramped notches shear entrained solids between rotating and stationary surfaces, preventing jamming while maintaining high pumping efficiency.
- Riserless Molten Metal Pump Vortex Mixing
A riserless pump uses a hybrid-drag turbine to create a forced vortex for lifting and mixing molten metal.
- CMC Cap Bolt Attachment for Turbine Engine Thermal Management
A metal bolt secured with a ceramic matrix composite cap manages thermal expansion differences in turbine engine assemblies.
