Abstract
An ultrasonic wave type bubble removing system for removing bubbles from a first liquid from which bubbles should be removed, by imparting ultrasonic wave vibration to the first liquid. A part of a liquid conduit is provided in an ultrasonic wave liquid tank which has an ultrasonic wave oscillator and is filled with an ultrasonic wave propagating liquid. An absolute pressure of 1.3 Kg/cm.sup.2 or higher is maintained applied inside the liquid conduit. Ultrasonic wave vibration generated by the ultrasonic wave oscillator is imparted to the first liquid which is continuously delivered without causing a vapor-liquid interface in the liquid pipe, to dissolve the bubbles in the first liquid and to prevent deposition of bubbles under the atmospheric pressure.
