Recently, a certain air force station organized support training under severe cold conditions to solve the problem of "nitrogen replenishment completed, all parameters are normal...". Inside the machine shed, Sergeant Su Deming used a self-developed nitrogen charging vehicle heating device to quickly complete nitrogen replenishment, achieving on-demand nitrogen replenishment under severe cold conditions. This is a microcosm of the station's promotion and application of the innovative achievements of officers and soldiers, and its efforts to solve security problems. "These innovative achievements are practical and effective, making equipment fearless of severe cold weather." The station leader introduced that the low temperature in the station this winter has put forward high requirements for the cold resistance performance of the equipment. During a recent training session, the compressor of a nitrogen filled vehicle was frostbitten, causing the fighter jet to take off beyond the specified time limit and affecting the completion of the mission. "Overcoming the shortcomings in ensuring the security of cold regions requires collective planning and efforts." At the preliminary discussion and training meeting held by the station party committee, station leaders encouraged officers and soldiers to base themselves on existing equipment and technology, be brave in innovation, and boldly innovate. In this way, a group of technical elites who understand principles, are skilled in hands-on work, and have sufficient experience formed an innovation team, active in the front line of security, and gathered intelligence to overcome multiple technical difficulties that affect the improvement of security quality and efficiency. The air-conditioned car runs for a long time under low temperature conditions, resulting in delayed data display on the digital LCD screen of the controller, and the operator cannot accurately monitor parameters. First class sergeant Tian Dewei led a team to study and demonstrate that an electric heating plate and temperature control device were installed on the back of the screen to ensure that the digital LCD screen can stably display readings; When the compressor of an air-conditioned vehicle cools down, the pipeline is prone to freezing and causing blockages in the air path. The air path deicing device independently developed by Sergeant Gao Kejun can timely warm the electric heating wire of the vehicle, effectively preventing air path icing. It is understood that multiple innovative achievements of officers and soldiers at the station have been promoted and applied through practical testing, effectively solving the problem of support under severe cold conditions. Next, they will continue to increase their research and research efforts, continuously improve the practicality of innovative achievements, and provide technical support for high-quality protection in cold regions.
