发明名称 ELECTRONIC CONTROL METHOD AND SYSTEM FOR A PIEZO-ELECTRIC PUMP
摘要 <p>A method for actuating a pumping device with an optimal driving voltage, the pumping device comprising a pumping chamber (4) having a pumping membrane (1), an inlet (3) and an outlet chamber (5), a voltage controlled actuator (6) connected to said pumping membrane (1), a stop position defined by a mechanical stop (2), a sensor for determining whether the pumping membrane has reached said mechanical stop (2); said method comprising a learning and working phase, the learning phase comprising the following steps -) actuation of the pumping membrane (1) by applying a predetermined actuation voltage V act to the actuator (6), said pumping membrane (1) reaching said position in an over-actuation step or not reaching said mechanical stop (2) position in an under-actuation process; -) after the over-actuation step, decreasing the voltage so that the pumping membrane (1) has left said mechanical stop (2) position and storing as the optimal voltage V act optimal or -) in the under-actuation step, increasing the voltage so that the pumping membrane (1) reaches said mechanical stop (2) position and storing as the optimal voltage V act optimal -) actuating the pumping device in the working phase with the determined optimal voltage value V act optimal .</p>
