Pump Control TRIZ Cases
- Drilling Device Compressor Unload Control for Energy Efficiency
Dynamic pressure switching between low and high states reduces compressor load and fuel consumption while maintaining reliable dust removal performance.
- Variable Displacement Pump Service Pack for Work Vehicles
A service pack with a variable displacement pump adjusts hydraulic output to match engine load demands.
- Centrifugal Pump Blockage Detection via Fourier Spectral Analysis
Fourier transform of acceleration and current signals detects blockages, preventing damage from solids content.
- Pump Assembly Control via Dynamic Limit Adjustment
A pump assembly adjusts operating limits to switch between base-load and peak-load modes without prior characteristic curve measurements.
- Vehicle Brake Suction Valve Control Using Back-EMF Detection
A control unit detects back electromotive voltage to determine motor stop completion for a vehicle brake suction valve.
- Turbopump Magnetic Torque Generator for Intermediate Regime Control
A magnetic torque generator applies selective electromagnetic force to a turbopump drive shaft for precise speed regulation.
- Fan Motor Controller Circumferential Mounting for Weight Reduction
Circumferential mounting of controller components minimizes cooling airflow bleed, enhancing fan efficiency by integrating metalized interconnects.
- Motor Drive Gulping Detection via Work Indicator Tracking
A motor drive detects pump gulping by monitoring work indicator values and adjusting a tracking variable based on threshold comparisons.
- Variable Displacement Compressor Suction Control for Vibration Reduction
A variable displacement compressor uses an opening control valve to adjust suction passage flow based on pressure differences.
