摘要
正压式消防空气呼吸器的整机质量过大会对消防员形成极大的体能消耗,造成实际呼吸保护时间大幅缩短,不仅严重影响消防救援作业效能,还可能为消防员的人身安全埋下重要安全隐患.本文介绍了一种正压式消防空气呼吸器用轻质Ⅲ型缠绕复合气瓶的研制过程及关键技术.通过优化气瓶结构,采用高强度新材料等方式,实现瓶体质量比同类产品降低22.3%,并且瓶体承载能力和安全性均有显著提升,可明显减轻消防员生理负担,延长呼吸器的呼吸防护时间.
Abstract
The overall weight of SCBA can cause great physical exertion on firefighters,causing the actual respiratory protection time to be greatly shortened.Not only will it seriously affect the efficiency of fire and rescue operations,but it may also create im-portant safety hazards for firefighters'personal safety.This article introduces the development process and key technologies of a lightweight type Ⅲ fully wrapped composite gas cylinder for SCBA.By optimizing the structure of the cylinder and using high-strength new materials,the mass of the cylinder is reduced by 22.3％compared with similar products,and the carrying capacity and safety of the cylinder are significantly improved,which signifi-cantly reduces the physiological burden on firefighters and pro-longs the breathing of the respirator.
