Specific Fluid Pumps TRIZ Cases
- Dual Seal Arrangement for Abrasive Pump Leakage Control
A mechanical seal backed by a gland seal and pressurized liquid cavity limits slurry leakage and keeps pumps running after seal failure.
- Blood Pump Bearing Geometry for Flow Washing and Clot Reduction
Modified sleeve and cone bearing geometry improves blood washing and lubrication in pump bearing regions to reduce thrombosis and hemolysis.
- Reversible In-Line Pumping for Gravity Drain Blockage Clearing
Reversible impeller pumps boost gravity drain flow and shred solids to clear blockages without enlarging existing piping.
- Molten Metal Rotor-Shaft Locking Structure for Breakage Prevention
A projection-and-abutment rotor-shaft joint transmits driving force in molten metal equipment while preventing coupling breakage and easing removal.
- Blood Pump Bearing Geometry for Thrombosis-Resistant Flow
Modified sleeve and cone bearing geometry keeps blood washing through pump bearings to reduce clotting and hemolysis risk.
- Nuclear Coolant Pump Seal Chambers for Balanced Pressure Staging
Rotor-accelerated coolant flow balances pressure drop across seal chambers, reducing leakage and uneven wear in nuclear coolant pumps.
- Carbon-Coated Pressure Cover for Abrasion-Resistant Centrifugal Pumps
A ta-C carbon layer on the pressure cover cuts abrasive wear in solids-handling centrifugal pumps while protecting the shaft seal seat.
- Boom-Mounted Pump Counterbalance Layout for Stable Manure Transfer
Counterbalancing the boom with the engine and a second pump improves manure transfer stability on uneven ground while reducing footprint and swivel risk.
- Segmented Blood Pump Bearings for Washed Flow Paths
Segmented sleeve and cone bearings create washed flow paths and lubrication in blood pump bearing regions to limit clotting and hemolysis.
- Pump Housing Grooves for Hygienic Seal Flushing
Grooves through the pump rear wall create a pressure gradient that flushes seal cavities, improving cleaning and reducing particle contamination.
- Deformable Thrust Bearing Angle for Variable-Speed Blood Pumps
A passive deformable thrust bearing changes pocket depth and angle with pump speed to reduce load and maintain blood pump efficiency.
- Blood Pump Bearing Geometry for Washed Flow Paths
Segmented sleeve and cone bearing geometry improves blood washing and hydrodynamic lubrication to reduce clotting and hemolysis.
- Composite Metal Wear Components With Localized Cavity Protection
Cast-in cavities hold bonded wear-resistant inserts in high-erosion zones, extending slurry pump and liner life without changing flow geometry.
- Asymmetric Pump Impeller With Internal Cavities for Balance Control
Internal cavities formed by additive manufacturing shift the inertia axis of an asymmetric pump impeller to cut imbalance and post-balancing.
- ESP Seal Section Additives for Wellbore Fluid Contamination
Chemical additives in ESP seal sections absorb or react with wellbore fluids to protect motor oil and extend pump run-life.
- Pump Seal Pressure Control for Volatile Liquid Leakage
Maintaining a constant barrier-gas pressure difference helps pump seals contain volatile liquids, prevent atmospheric leakage, and protect seal faces.
- USPCD Bearing Assembly With Tilting Pads for ESP Wear Resistance
Catalyst-free USPCD bearings use tilting pads and resilient members to resist erosion, corrosion, vibration, and impact in ESP systems.
- Blood Pump Bearing Assembly for Washed Flow and Clot Reduction
Segmented sleeve and cone bearings keep blood washing through support regions, reducing stagnation, clotting, and hemolysis in assist pumps.
- Wind Farm Data Normalization for Unified Monitoring Control
An intelligent management server standardizes namespaces and data types across wind farms for uniform monitoring, comparison, and secure access.
- High-Pressure Pump Seal Chamber Oil Barrier Against Fluid Leakage
Pressurized oil in the seal chamber stays above fluid pressure to block supercritical CO2 or H2S leakage, even during power failure.
- Segmented Blood Pump Bearings for Thrombosis and Hemolysis
Segmented sleeve and cone bearings improve blood washing and lubrication in pump bearing zones, reducing thrombosis and hemolysis risk.
- Split Ceramic Journal Bearing for Molten Metal Pump Reliability
Segmented ceramic bushings, cone rings, and band springs simplify molten metal pump bearing manufacture while preventing tearing and misalignment wear.
