摘　　要：为研究不同产气剂用量和产气室容积对产气驱动式全氟己酮灭火装置工作可靠性的影响,参考相关标准规定的技术要求及试验方法,验证灭火剂充装量为0.8 kg灭火装置的喷射时间、喷射过程及状态。研究结果表明:灭火装置安全泄放装置动作、喷射效果不佳或无法喷射主要是由产气剂的用量与产气室容积不匹配导致的;在计算灭火装置内部压力时要留有充足的安全冗余,以防止灭火装置无法正常喷射;要考虑产气剂的发热量,使得启动灭火装置后其内部压力的理论计算值与实际压力值更接近。因此,根据灭火剂的充装量调整产气剂的用量和产气室容积,可以提高灭火装置的可靠性,增强灭火剂的雾化效果,从而实现更优的灭火效果。To investigate the influence of different gas generator dosages and gas chamber volumes on the operational reliability of a gas-driven perfluorohexanone fire extinguishing device,this study references the technical requirements and testing methods outlined in relevant standards.The validation focuses on the injection time,injection process,and state of the fire extinguishing device with a charge amount of 0.8 kg of extinguishing agent.The research findings indicate that the activation of the safety release mechanism and suboptimal or ineffective injection of the extinguishing agent are primarily caused by a mismatch between the gas generator dosage and the gas chamber volume.It is essential to incorporate adequate safety margins when calculating the internal pressure of the fire extinguishing device to prevent failure in normal injection.Furthermore,consideration must be given to the heat generation of the gas generator to ensure that the theoretical calculations of internal pressure align closely with actual pressure values after activation of the fire extinguishing device.Consequently,adjusting the gas generator dosage and gas chamber volume based on the charge amount of the extinguishing agent can enhance the reliability of the fire extinguishing device and improve the atomization effect of the extinguishing agent,thereby achieving superior fire suppression performance.
