Fluid Parameter TRIZ Cases
- Double Diaphragm Pump Independent Actuator Control
An independently controlled double diaphragm pump eliminates periodic supply pressure drops by offsetting actuator timing.
- Automated Air Venting in Closed Fluid Systems
Pulsed flow sequences automate air removal from closed fluid systems, eliminating manual technician intervention.
- Hydraulic Bypass Valve for Low Side Pressure Control
A hydraulic bypass valve opens during shock loads to transfer fluid from the high side, preventing low loop events without accumulators.
- Integrated Piston Valve Governor for Compressor Pressure Control
Integrating the valve arrangement within the piston eliminates external fasteners and reduces mechanical complexity while controlling compressor operation.
- Variable Displacement Pump Turbine Efficiency Optimization
A variable displacement hydraulic pump adjusts volumetric output to match turbine speed, maintaining optimal engine efficiency across varying downhole loads.
- Variable Displacement Pump Pressure Feedback Control
A variable displacement pump adjusts output pressure via a mechanical linkage driven by a pressure actuated piston.
- Piezoelectric Ceramic Air Pump Integrated Inlet and Outlet Ports
Peripheral inlet and outlet ports on a tubular piezoelectric air pump reduce pipeline resistance and dead cavity volume.
- Compressor Discharge Pressure Control for Stable Supply
A compressor control mechanism adjusts discharge pressure ranges to maintain stable terminal supply pressure.
- Liquid Flow Apparatus with Reversible Gauge Mounting
A liquid flow apparatus uses a reversible gauge holder body to enable pressure monitoring via a dedicated fluid channel.
- Compressor Inlet Throttling for Pressure and Power Optimization
A compressor system uses variable inlet throttling to adjust flow rate and maintain desired operating pressure levels.
- Variable Pressure Buffer for Pump Delivery Control
A pretensioned pressure buffer absorbs delivery line pressure fluctuations to stabilize the metering pump inlet.
- Frequency Converter Pump Flow Control via Torque Detection
Torque-based flow estimation eliminates external sensors, preventing pump overheating and reducing maintenance costs.
- Liquid Processing Apparatus Filtration Throughput Control
A liquid processing apparatus uses a single filter and pump to synthesize process liquid for repeated filtration cycles.
- Variable Displacement Pump Actuator with Dual Hydraulic Actuators
Segmenting the actuator into two symmetric units eliminates directional asymmetry, ensuring identical load holding and slew rates in both directions.
- Micropump Dead-Zone Seal Section for Gas Bubble Isolation
A micropump dead-zone seal section surrounds the rotor to isolate internal gas bubbles from the liquid delivery path.
- Hydraulic Pump Reservoir Purge Preventing Reductant Freezing
A hydraulic pump reservoir vents to atmospheric pressure via a timer reservoir and orifice during shutdown.
- Pump Dry Running Detection via Variable Resistance Structure
An electrical resistance structure in a pump inlet changes value based on liquid wetting to detect dry running conditions.
- Cryogenic Pump Pressure Control via Pre-cooled Gas Injection
Pre-cooled gas injection into the storage tank sustains suction pressure without heating liquid hydrogen, extending pumping duration.
