Reduction Of Noise Of Compressors Of Volumetric Type By Using Of Noise Muffler – Pulsations Damper

Abstract

The problems of noise reduction arising during the operation of volumetric compressors are considered. A new noise suppressor is presented – a pulsation suppressor for volumetric compressors, which allows to effectively reduce noise and pressure pulsations at the output of a volumetric compressor both in a wide range of frequencies and at discrete frequencies in combination with a minimum pressure drop. A design model and an equivalent circuit of a noise suppressor – a pulsation suppressor are presented, and the design of its prototype is described. The results of tests of a noise suppressor – a pulsation suppressor for various structural designs are given. It is concluded that the use of a prototype noise suppressor – pulsation suppressor gives a high effect of reducing noise and gas pressure pulsations.
