铸造车间中较多地采用了各种类型的风机按其用途主要可归纳为三类:一是工艺上用作向冲天炉送风的罗茨风机、气力输送用的高压离心风机等;二是用作除尘通风系统的中低压离心通风机;三是用作全面通风换气或局部降温的轴流通风机。这三类风机都产生高强噪声,严重地污染环境。铸造车间也常采用压缩空气作为某些动力源,空压站内的空气压缩机也产生一定的高强噪声,影响环境。
Casting workshop to use more of the various types of fans according to their uses can be grouped into three categories: First, the process used to supply the cupola Roots blower, pneumatic conveying high-pressure centrifugal fan, etc .; the second is Used as dust removal ventilation system in the low-pressure centrifugal fan; Third, as a full ventilation or local cooling axial flow fan. These three types of fans have high-intensity noise, seriously pollute the environment. Casting workshop also often uses compressed air as some power source, air compressor station within the air compressor also produces some high-strength noise, affecting the environment.
