便携式气体检测仪的维护方法研究

The Usage andmaintenancemethods of Portable Gas Detectors

石油化工企业中进入有限空间作业频繁,危险因素多,易发生人员伤亡事故,所以石油化工企业要求进入有限空间前必须办理作业许可证。判断是否允许进入的重要依据之一就是检测有限空间中可燃气体、有毒气体及氧气的含量,而此项检测的完成现大多采用便携式气体检测报警仪。本文介绍了便携式气体检测报警仪常见的故障及维护的方法。

In petrochemical enterprises,entering confined spaces for operations is frequent,withmany hazardous factors and the risk of personal injury and death accidents.Therefore,petrochemical enterprises require obtaining a work permit before entering confined spaces.One of the important criteria for determining whether entry is allowed is to detect the content of combustible gases,toxic gases,and oxygen in limited spaces,and the completion of this detection ismostly achieved using portable gas detection alarm devices.This article introduces the common faults andmaintenancemethods of portable gas detection and alarm devices.
