Abstract

PURPOSE: To perfectly arrest sounds, by arresting sounds with low-frequency in a blower body by menas of an interference system sound arrestor and an absorption system sound arrestor at the intake side and by means of an interference system sound arrestor at the discharge side.
CONSTITUTION: An elbow type interference system sound arrestor 4 in a sheet is connected to an intake port of a root blower 1 installed into a water tank 2 through a buffer material 3, and an absorption system sound arrestor 9 is further connected through suction pipings 6, 7. An elbow type interference system sound arrestor 10 in a sheet is also connected to a discharge port of the root blower 1. Sounds with low frequency generated in the root blower 1 transmit an outer wall of the blower 1 and the thin wall surfaces of the interference system sound arrestors 4, 10, one portion is diffused in water, remaining sounds with low frequency are pulsation removed by the interference action of contraction, expansion, bending,etc. in the sound arrestors 4, 10, uniformalized and converted into sounds with high- frequency, and sounds are further arrested by means of the absorption system sound arrestor 9 at the intake side.
