摘要
长管呼吸器也称为长管供气式呼吸器,长管呼吸器是呼气防护装备的一个重要类别。长管呼吸器使佩戴者的呼吸器官与环境空气隔绝,并通过导气管引入可呼吸气体,长管呼吸器分为自吸式长管呼吸器、连续供气式长管呼吸器和按需供气式长管呼吸器3种类型。长管呼吸器可以提供作业人员较高水平的防护。本文重点介绍连续供气式长管呼吸器的结构和特点,及连续供气式长管呼吸器的应用。
Supplied airline respirators are one of the most important categories of respiratory protective equipment.A supplied airline respirator isolates the wearer's respiratory organs from the ambient air and introduces breathable gas through an airline.There are three types of supplied airline respirators based on the air supply methods:Fresh air line respirators,continuous flow compressed airline respirators,and compressed airline respirators with demanded valves.Supplied airline respirators can provide workers with a higher level of protection.This paper discussed the application of continuous flow compressed airline respirators based on their structure and characteristics.
