Rotary Piston Pumps TRIZ Cases
- Electric Liquid Pump With Thermosetting-Resin Shaft Support
Replacing metal bearings with thermosetting-resin support and circulating liquid helps reduce pump weight, torque, and overall size.
- Aluminum Sliding Component Alloy for Strength and Anodizing
Controlled Si, Cu, Mg, Mn, Fe, and Cr levels limit coarse phases while supporting 330–380 MPa strength and 400 HV anodized films.
- Multi-Stage Progressing Cavity Rotor–Stator Coupling for High Solids
Adjustable rotor–stator clearance helps multi-stage progressing cavity assemblies handle high-solid-content fluids with less wear.
- Hybrid Gear-Rotor Pump for Higher Displacement And Viscous Flow
Combining gears and rotors in one assembly increases displacement while supporting viscous-fluid transport and reducing pump complexity.
- Variable-Capacity Compressor Control for Switching Vibration
Check valves and throttling elements sequence refrigerant flow to reduce vibration and prevent compressor shutdowns during capacity switching.
- Modular Trochoidal Medicament Pump With Reusable Drive Unit
Reusable motor-gear and control units couple with disposable pump units to improve dosing accuracy, adaptability, and safe medicament delivery.
- Asymmetric Pump Rotor for Grinding Without Particle Entrapment
This pump rotor uses flat and rounded edges to grind inhomogeneous materials while preventing particle entrapment.
- Compressor System Measured-Value Standardization Through Context Metadata
Context metadata standardizes measurements from varied compressor sensors, enabling consistent control, monitoring, and diagnostics.
- Rotary Vane Pump Axial Chamber Modulation for Variable Capacity
An axially extendable vane chamber varies pump capacity without enlarging radial size, while a closed loop balances drive and load forces.
- Uniaxial Eccentric Screw Pump With Variable Contact Pressure
Variable contact pressure across the stator opening balances rotor sealing tightness, friction, and driving force for smoother fluid delivery.
