2. 船用七氟丙烷灭火装置技术说明
technical explanation of the marine hfc-227ea fire suppression plant
2.1用途  application
本装置用于贮存保护机舱、货泵舱和油库等保护区所需求的七氟丙烷灭火剂，本系统可采用组合分配的方式，经过人工遥控操作或就地应急手动操作启动，也可采用单元独立系统手动操作方式启动，七氟丙烷灭火剂由输送管路从被保护舱室的喷嘴喷入被保护舱室内，将火予以扑灭。
the plant is used for the storage of hfc-227ea agent which can protect the engine room, cargo pump room, oil depot and other area from fire hazard. the system can be started by manual remote operation or local emergency manual operation, in a combined distribution way, likewise, it can be started by manual operation in a unit independent way. when fire occurs, hfc-227ea agent can spray into the protection cabin from the nozzle through the pipeline and put out the fire immediately.
机舱、泵舱等施放方式分为：手气两用或手动施放二种。
the releasing way in engine, pump room, etc. can be divided into: manual & pneumatic or manual
机舱、泵舱等手动操作采用拉动拉环形式启动七氟丙烷灭火装置。
the engine room, pump room, etc. adopt the manual operation of tab-pulled form to start the hfc-227ea plant.
货舱、油库等用手动操作方式，立即释放，没有延时时间。
the cargo hold, oil depot, etc. adopt the manual operation to release the agent instantly, without any delay time.
