Fluid Parameter TRIZ Cases
- Hydraulic Drive Pressure Control Using Motor Speed Feedback
Using motor speed as the control input, this case stabilizes hydraulic output pressure across variable flow and wide pressure ranges.
- Bootstrap Accumulator Piston Bypass Valve for Closed-System Pressure Relief
An integrated piston bypass valve relieves over-pressure and purges air inside a bootstrap accumulator without external venting or added components.
- Pump Current and Head Monitoring for Predictive Maintenance
By comparing pump current against liquid level-derived static head over time, this case helps detect degradation and avoid unnecessary servicing.
- Motor-Driven Oil Pump Torque Control for Stable Sensorless Operation
Preemptive motor torque increase before discharge pressure rises helps a hydraulic oil pump maintain speed and avoid sensorless loss of synchronism.
- Integrated Pump Control With Cloud Monitoring and Predictive Alerts
Built-in sensing and PLC-VFD feedback improve pump control accuracy while enabling cloud monitoring and predictive maintenance alerts.
