Welding workshop dust acoustic equipment

Welding workshop dust acoustic equipment welding workshop dust-removing component separated the noise source and the receiver, the spread of sound isolation air, and sound insulation, noise reduction methods is called the component is sound insulation structure. Sound insulation junction 枃 mainly include single layer and double layer structure composed of single component and lightweight composite structures, etc. Sound insulation between the welding workshop dust collector design considerations (1) welding workshop dust to understand exactly the characteristics of noise source, accurate calculation of sound insulation between the sound source to noise sound pressure level (2) according to the standards and specifications to determine the sound insulation between the noise level is allowed. Establish sound insulation in high noise workshop, indoor noise control at 60 ~ 70 db ( A) Is more appropriate. (3) the sound insulation between the geometry size have been identified or subject to the limit of the space under the premise of according to determine the amount of comprehensive sound insulation, sound insulation wall, door, window layout, between the amount of application of transmission principle, after the trial, to meet the trial of sound insulation quantity less than or equal to the comprehensive integrated sound insulation condition, the amount of acoustic components are selected, and then determine the installation method. When sound insulation between the geometry is not subject to strict control, or sound insulation between the larger area, according to determine the amount of sound insulation, sound insulation coefficient and transmission principle of quantity, selected acoustic components first, and then determine the sound insulation between the geometry size and configuration of walls, doors, Windows, roof area, to determine the installation method. (4) in the high noise workshop acoustic control room, factor of the surface by sound, to indoor sound energy is larger, interior wall to make acoustic processing, is beneficial to the improvement of the actual amount of noise. If a line ( Duct, cable pipe, etc. ) Through the wall structure, must add wear casing wall, strict sealing, to prevent leakage. (5) sound insulation between to ensure the indoor air circulation, the right temperature.
