Positive Displacement Pump Components TRIZ Cases

Variable bore sections let tie rods pass through a high-pressure pump fluid end without intersecting valve seat bores or standard components.

Opposing pivot clamps respond to tube force, simplifying insertion and removal while supporting tube-size changes without removing the retention device.

A shared valve inlet directs flushing agent and compressed gas through the supply line and conveying chamber, reducing cleaning time and waste.

Two independent inflation assemblies operate together to increase airflow, raise pressure, and shorten filling time for larger devices.

Parallel plunger barrel units simplify diesel fuel pump processing while a shared discharge channel suppresses pressure pulsation.

Discharge flow from the valve cools the pump housing and vibrator, removing the heat sink for a smaller fluid control device.

Separating the dynamic and static sections simplifies inspection and component replacement while preserving an in-line high-pressure pump layout.

Gas-filled resonators arranged around subsea pumps and compressors attenuate low-frequency noise under deepwater pressure.

A toroidal surface at the fluid-end bore intersection spreads stress, reducing concentrations and helping prevent stress cracking.

A swash-plate pump uses separate plungers and pressure valves to raise hydraulic pressure quickly while reducing motor load.

Isolation elements suspend the fan assembly from the housing and outlet duct, reducing noise and vibration while preserving airflow.

An inlet-connected flushing path cleans the coating supply line and material conveyor together, reducing manual cleaning, detergent use, and carryover.

Compressed hydrogen flows through pressure-packer channels to remove seal heat while preserving compressed-gas purity.

Varying piston displacement changes pressure impulses and frequency distribution, creating a less sharp sound while retaining audible pump feedback.

Releasable connectors allow head-tube replacement without disconnecting fluid lines, reducing connector damage and reconnection work.

Fixed outlet orientation limits inflator versatility; a rotatable outlet redirects airflow for easier inflation and deflation.

An intermediary sliding bush guides eccentric motion to reduce piston pump friction, wear, noise, and assembly costs.

A balance disk and narrow-neck overflow path stabilize dual oil outlets, reducing pipeline complexity and protecting outlet check valves.

A stacked valve body opens forward flow and seals reverse flow, balancing high throughput with backflow prevention in compact devices.

A rotating pump body and housing switch trigger retain mechanical on/off control when the pump is integrated or used separately.

A ternary R-32, R-1234yf, and R-600a blend addresses high discharge temperatures that can shorten hermetic compressor longevity.

The linear turbine-engine, gearbox, transmission, and plunger-pump layout targets bulky fracturing equipment with steadier power transfer.

Inclined mounting holes and bracket support limit auxiliary-pump movement while distributing loads to reduce stress on bearings.

Recirculated hydrogen channels absorb compressor heat and protect seals without contaminating or releasing the compressed gas.

Integrated heat exchangers and fan paths cool hydraulic-fracturing DDU process fluid while limiting cooling-package footprint and energy loss.
