Noise and vibration in a clean room


Dongguan clean room project:

选址:振动、土质和将来场地的发展; b) 结构设计:无尘车间楼面支撑、刚性、隔离缝; c) 机械设计:设备选型、系统设计、性能规格、隔振系统、噪声控制系统(内部和外部); d) 建筑布局:建筑和设施的布置图,绿化区、服务系统。 I) Site selection: vibration, soil quality and future site development; b) Structural design: Floor support, rigidity, isolation joints in the clean room; c) Mechanical design: Equipment selection, system design, performance specifications, vibration isolation system, Noise control system (internal and external); d) building layout: layout of buildings and facilities, green areas, service systems.

声压级应该根据人员的舒适和安全及环境(如其它设备)产牛的背景声压级来选择需要的声雎级。 F.4.2 The sound pressure level should be selected according to the comfort and safety of personnel and the background sound pressure level of the cattle (eg, other equipment). Cleanroom. A-1J 权声压级范围在 55 dB - 65 dB The diffused standard A-1J weighted sound pressure level ranges from 55 dB to 65 dB . Some applications may require lower levels or tolerate higher levels. IS0 3746 进行。 Noise control measurements should be made in accordance with ISO 3746 .

洁净室设施巾振动是个需要考虑的重要问题,凶为它对工艺、人的舒适和设备及系统的有效使用期限都会产生不利的影响。 F43.1 The vibration of clean room facilities is an important issue to be considered. It is believed that it will adversely affect the technology, human comfort and the effective life of equipment and systems.

净化车间 设施中应通过采用优质风机和振动控制设备等方法尽可能减少振动,或把振动源隔离。 F.43.2 Purification workshop Vibration shall be minimized in the facility by using high-quality fans and vibration control equipment, or the source of vibration shall be isolated.

如要求控制振动,应按 IS0 1940-1 IS0 10816-1 规定允许的级别。 F.4.3.3 If vibration is required to be controlled, it shall be in accordance with the level allowed by IS0 1940-1 and IS0 10816-1 .

节能. F.5 Energy saving. r1 ,应该考虑节能措施,如在没有任何活动时减少或关闭温度和湿度控制,降低空气流速。 When designing r1 , energy-saving measures should be considered, such as reducing or turning off temperature and humidity control and reducing air flow when there is no activity. However, it should be able to return to the conditions of use within the specified self-purification period.
