摘要： A fluid feeding pump which varies a volume of a pump chamber and thus feeds a fluid out of the pump chamber, includes: a piezoelectric element which accumulates electric charges inside when a voltage is applied, and which deforms according to an amount of accumulated electric charges and thus increases or decreases the volume of the pump chamber; a drive unit which applies a drive signal with a waveform increasing to a predetermined maximum voltage and then decreasing, and thus drives the piezoelectric element; and an air bubble determining unit which detects a current flowing through the piezoelectric element within a predetermined period after the drive signal is applied to the piezoelectric element, and thus determines whether there are air bubbles in the pump chamber or not.

摘要： A pump chamber is connected to an outlet-side buffer chamber via an outlet channel, and pumps a liquid from the outlet-side buffer chamber. A pressure vibration generated within the pump chamber when the volume of the pump chamber is decreased includes various kinds of information relating to the operating states of the liquid feed pump, such as mixing of bubbles, pumping pressure, dissolved gas amount, and liquid feed amount. Thus, it is possible to detect the pressure vibration, thereby simply and easily detecting the various kinds of information relating to the operating states of the liquid feed pump.
