实验室集中供气系统设计探讨

发布时间:2019-08-21 14:50来源:TMOON点击:

  

  完善的实验室供气系统是实验室仪器设备正常工作的基础,对实验室集中供气的优点进行了分析和优化。实验室供气系统的设计涉及到诸多因素,从气瓶室、管道铺设、材料选择、管道连接、安全技术要求等多方面考虑,设计的目的性要强,安全应放在第一位,并按照实验室的用气种类进行统筹规划。对实验室集中供气系统设计进行了探讨,为实验室规划设计提供参考。

  


  


  实验室集中供气系统由于操作简单、气流稳定、使用安全、运行成本低等特点,已作为当前广泛使用的现代供气方式。其系统主要由气源切换、供气管道、调压装置、用气点、监控及报警等系统组成。实验室集中供气系统涉及到管道如何布置、材料质量及规格如何选用、各阶段安装步骤和要求、工程验收等方面工作,一个好的实验室集中供气系统的设计需要统一考虑气体使用的安全性、便利性、以及管理和维护等问题,同时要考虑到实验室今后发展的需要,对于特殊气体还要考虑特殊的技术解决方案。因此,在实验室集中供气的设计时需要统筹规划,结合用户的实际情况,按照相关标准和规范进行设计。
