项目一压缩空气系统设备选型(续)6低位排水装置的选择压缩空气系统的支管路从主管路的顶部引出的目的就是为了防止主管路里的水流入支管路,但管路底部积存的水必须排走,因此在支管路末端每个低位都要安装低位排水装置,以将管路中的水分通过导流管收集到指定容器或排给管线中而排出,确保压缩空气质量。排水点在气管的低处,安装三通接头引出,排水可定期由人工完成或安装自动排水器。但大多数管路在设计安装时都忽视了这一点,要么没有低位排水
Project A Selection of compressed air system equipment (cont’d) 6 Selection of low-level drainage system The branch line of the compressed air system is led out from the top of the main pipeline in order to prevent the water in the main pipeline from flowing into the branch pipeline, but the water It must be drained away. Therefore, low-level drainage devices should be installed at each low end of the branch pipeline to discharge the water in the pipeline through the diversion pipe to the designated vessel or to the pipeline to ensure the compressed air quality. Drains at the lower end of the trachea, the installation of tee leads to lead, drainage can be done by hand or install automatic drainage. However, most of the pipelines are neglected in the design and installation, or there is no low drainage
