为了工业建筑的热风采暧,苏联正采用超过50万台的热风供暧机组。它们的采用使建筑物采暧的基本费用缩减到了最小限度,使安装价格下降和减少了金属用量。但是,虽然具备上述的优点,机组重要的部件具有声音嘈杂的特点,噪声给予在车间工作的人们的身体以有害的影响。大家知道,过分的噪声使人的工作能力下降,而噪声只要减少1分贝,就获得劳动生产率增加0.3～1％的效果。水暖器材公司第一机械工厂是苏联规模庞大的循环式热风供嗳机组的制造厂家。近年来鉴于要求控制噪声的性能,机械工厂正在进行
The Soviet Union is using more than 500,000 hot air supply units for industrial buildings. Their adoption has reduced the basic cost of building picks to a minimum, reduced installation costs and reduced metal usage. However, despite these advantages, the important components of the unit have noisy features, and the noise gives harmful effects on the body of people working in the workshop. As we all know, excessive noise causes people’s ability to work, and as long as noise is reduced by 1 decibel, labor productivity will increase by 0.3 to 1%. The first machinery factory of plumbing equipment company is a manufacturer of large scale circulating hot air supply units in the Soviet Union. In recent years due to the requirement to control the performance of noise, the machinery factory is in progress
