Abstract

PURPOSE:To minimize the vibration-originated stress for safety by controlling the volume of gas mixed in the liquid contained in a liquid-containing vessel such as a reactor container, and by restraining the structures from vibration. CONSTITUTION:Regulation of the number of revolutions of a blower 13 as well as the open-angle of a valve 15, ejects the gas (air), stored in a bottle 10, into a pool 8, via a filter 11 and a flow meter 12, from piping 9 in a container 1. With a power source 17, a vibration sensor 16, sixed within the container 1, senses the vibration and send the signal to a controlling board 14, which reads the frequency. If the frequency differs greatly from the target-valve, adjustment is made on the number of revolutions of the blower 13 as well as the open-angle of the valve 15 in order to regulate the air supply. With this contrivance, the natural frequency of the container 1 can be specified at the farthest value from the pressure pulsating frequency.
