管道噪声是影响室内环境的公害之一,直接影响着人们的正常工作和生活,甚至会影响健康。室内管道噪声主要包括供热管道噪声、给水管道噪声、排水管道噪声等。 1.室内管道噪声的产生 1.1 供热管道噪声的产生供热管道噪声的来源主要是管道的流水噪声、冲击噪声和摩擦噪声。对于间断运行的供暖系统,每天至少向系统大量补水一次,补水量越大,补水时间越长,供暖系统的流水噪声就越大,持续时间就
Pipeline noise is one of the pollution hazards to the indoor environment, which directly affects people’s normal work and life and may even affect their health. Indoor pipe noise, including heating pipe noise, water supply pipe noise, drainage pipe noise and so on. 1. Indoor Pipeline Noise 1.1 Generation of Heating Pipeline Noise The main sources of heating pipelines are the pipeline noise, impact noise and frictional noise. For intermittent operation of the heating system, a day at least to the system a lot of replenishment, the greater the amount of replenishment, replenishment time, heating system, the greater the water running noise, the duration
