呼吸空气系统典型构件(Typical Elements of a Breathing Air System)呼吸空气压缩机 DX过滤系统 空气分配系统(POA) 呼吸器The above pictured items make up a typical Grade-D breathing air system. Depending on the number of workers to be served by the system and whether the system needs to be portable or a fixed plant system, the size and complexity of the system may change. However, the basic elements above must be present. In order to properly size the breathing air system, it is absolutely essential that the user’s first decision is to decide the type and quantity of airline respirator(s) to be used. A quick recap of the airline respirator types and their required flow and pressure requirements is essential. All airline respirators are referred to by NIOSH as Type-C or Type-CE respirators. NIOSH approved CE respirators are designed for abrasive blasting but still require the same air flow as Type-C respirators.上图所示的是典型的DX呼吸空气系统的组成结构。系统是使用便携式或固定式、系统大小和复杂程度的变化都取决于使用人数。因此完全有必要X先让使用者来决定设备型号、数量来确定空气线路呼吸器的使用情况。 http://www.beijing-tech.com/?grade-d-filtration,224 |
