Abstract: According to the actual production needs, this paper proposes a fire suppression device for the safety protection of energy storage battery. In this paper, the overall structure and sealing property of the original pump type perfluoro fire suppression device are optimized, and the reliability of its function is verified through the sealing test and vibration test after the product assembly. It has certain reference value and significance for the research and development of pump type perfluoro fire suppression device and related equipment.
