Pump Testing TRIZ Cases

A control and safety model expands safe axial piston pump operating points by probing high-variance regions while limiting error and damage risk.

A rotating heated fixture simulates the pump body-end cover joint, tests multiple pump bodies at once, and captures load and modal data.

High-pressure fluid pre-conditioning beds in a liquid delivery valve quickly, improving sealing checks while cutting assembly time.

Pressure sensing and controller-based compressibility estimation correct air-related fluid measurement errors in medical diaphragm pumps.

Raw multi-sensor vibration signals and fine-grained imaging labels enable real-time centrifugal pump cavitation intensity prediction.

Permanent magnets moving with the adjustment piston replace jam-prone return levers, enabling compact, accurate swivel angle measurement.

Guide openings and guide elements align stator and sensor press-in contacts to the PCB, cutting tolerance-chain assembly complexity and cost.

Track movement relative to the rotor is used to infer tube pressure without fluid contact, cutting diaphragm cost, wear, and failure risk.

Holding the suction valve open during stoppage prevents discharge-valve leakage from building chamber pressure and damaging the bellows.

A dual-pressure bubble chamber traps and detects air in fluid lines, using pressure sensing and control to prevent bubble propagation.

Low-inductance springs gain reliable status detection by using magnetic amplification and oscillator frequency sensing in compact mechanical devices.
