Pump Components TRIZ Cases

Multi-stage cutting with a dedicated residue-cutting tool forms closed impeller flow paths where tight curvature limits single-tool machining.

A welded suction-side and pressure-side metal sheath protects a gas turbine fan blade core from debris impact and foreign object damage.

Centering pins, damping elements, and manual clamping enable fast tool-free pump mounting while maintaining precise alignment under vibration.

Millable counterweights and an anti-rotation tab let a gas turbine balance ring correct circumferential imbalance and reduce wear.

Pre-loaded stator pads and a shaft-coupled disc provide axial backup support in turbomachinery, reducing wear during magnetic bearing failure.

Localized welding holes let smaller ultrasonic horns join blades to the main plate and shroud, cutting impeller manufacturing cost and complexity.

A shared multi-hole washer spreads bolt load across compressor flanges to maintain sealing pressure and prevent leakage under heat and pressure.

Integrating radial and thrust bearing support with a fluid impeller simplifies turbomachine structure and improves bearing reliability.

Rough and fine mirror-guided laser alignment removes rotor material precisely on complex surfaces to cut imbalance and extend vacuum pump life.

Balanced tabs, notches, and spring-loaded features stop aircraft engine seal rotation during failure modes, preserving centering and limiting damage.

Counter-rotating impellers with embedded motors cut axial length and improve wet gas compression efficiency across mixed gas-liquid flows.

Directly depositing a metallic sheath onto a composite airfoil cuts fit-up and adhesive bonding time while maintaining erosion resistance.

Circumferential groove angles of 144°-216° raise air pressure between shaft and sleeve, enabling stable non-contact rotation.

A clip-retained balance pin corrects gas turbine rotor imbalance in tight spaces without material removal or special tooling.

Cooling holes through the thrust bearing raise airflow in a tight compressor space, lowering bearing temperature and damage risk.

A cut-and-clamp rotor repair replaces damaged compressor discs with solid-hub discs and a new shaft end, reducing cost and full shaft replacement.

Selective fluid passages and annular damper cavities vary shaft damping to cut gas turbine vibration, misalignment, and parasitic losses.

A turning part redirects towing force into the groove direction, enabling smooth blade ring removal without repositioning the towing unit.

Radial strakes in the turbocharger bearing housing oil core guide oil to the drain, limiting swirl, leakage, degradation, and coke formation.

Dry ice pellets sublimate inside metal AM supports to break them down in narrow overhang areas without deforming the printed part.

A groove-supported metal seal enables detachable turbomachine flange assembly while maintaining airtight sealing under heat, pressure, and thermal expansion.

A conical friction nut lets the blower wheel self-retension during operation, keeping the shaft connection secure while easing removal.

A concave-convex stainless steel base bonded to an engineering plastic layer improves impact resistance and maintains a stable water film.

A fitted column section aligns the shaft and compressor before threading, reducing assembly damage and improving fastening accuracy.

A split shear ring in matched cover and casing grooves simplifies barrel turbomachine cover removal while limiting size and material growth.

A retractable puck support and load cell stabilize horizontal gas turbine module assembly while reducing cantilever stress and extra scaffolding.

A 5-100 µm metal leading-edge layer with adhesive and insulation resists water droplet erosion while preserving composite blade lightness.

An integral front center body gutter captures and redirects lubricant to maintain flow in zero or negative gravity while simplifying assembly.

A converging-diverging bell-mouth suction inlet smooths slurry entry, cutting entrance losses and wear while improving pump performance.
