PUMP CALIBRATION SYSTEM AND PUMP CALIBRATION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18595792 titled 'PUMP CALIBRATION SYSTEM AND PUMP CALIBRATION METHOD
The abstract describes a pump calibration system that includes a hydraulic pump of a variable capacity type, a regulator that adjusts discharge capacity based on a command signal, an unloader valve with a variable opening degree, a pressure sensor for measuring discharge pressure, and a control device for calibrating the pump characteristic.
- The system stores a first reference pressure detected by the pressure sensor under a measurement condition with a fixed opening degree of the unloader valve and a predetermined rotation of the pump.
- When a calibration condition is met, the control device changes the command signal to make the discharge pressure equal to the first reference pressure and calibrates the pump characteristic based on the new command signal.
- This calibration process ensures accurate and consistent pump performance over time.
- The system allows for precise adjustment of the pump's output based on real-time pressure measurements.
- By calibrating the pump characteristic, the system optimizes efficiency and reliability in various applications.
Potential Applications: - Industrial hydraulic systems - Water treatment plants - Agricultural irrigation systems

Original Abstract Submitted
A pump calibration system includes a hydraulic pump of a variable capacity type, a regulator that changes a discharge capacity according to a command signal, an unloader valve having a variable opening degree, a pressure sensor that measures a discharge pressure, and a control device that controls the discharge capacity and calibrates a pump characteristic. The control device stores a first reference pressure detected by the pressure sensor when a first reference signal is output under a measurement condition in which the opening degree of the unloader valve is fixed and the pump is driven to rotate a predetermined amount, and when a calibration condition is satisfied, changes the command signal so that the discharge pressure becomes the first reference pressure, and calibrates the pump characteristic on the basis of a first actual signal that is the command signal with which the discharge pressure is the first reference pressure.
