某型舟桥装备驾驶室采暖除霜改进

Improvements of a Certain Pontoon Bridge Cab’s Frosting and Heating System

目的解决某型舟桥装备在严寒地区环境适应性试验中出现的采暖除霜问题。方法针对舟桥装备驾驶室采暖、除霜性能不足的问题进行故障树分析(FTA),对相关事件进行排查,提出整改措施,并在高低温综合环境模拟试验室进行验证。结果在-40℃环境下,驾驶室温度在20 min内达到20℃,前挡风窗玻璃内表面无结霜现象,外表面除霜面积达95%以上。结论增加燃油空气系统,更换电加热玻璃,在不影响装备正常使用和指标要求的前提下,解决了驾驶室采暖、除霜性能不足问题。

Objective To solve the frosting and heating problems of certain pontoon bridge in cold region environment adaptability test.Methods Problems of the frosting and heating was analyzed with FTA,the correlative event was inspected.Improvement measures were proposed.The effect experiment was carried out in a comprehensive environmental laboratory.Results In the-40℃environment,the cab’s temperature was heated to 20℃in 15 minutes,and.The interior surface of windshield had no frosting,and the exterior surface’s defrosting area reached over 95%.Conclusions In condition of requirements for normal use and performance,the insufficient problems of cab’s frosting and heating can be solved by adding fuel-air system and changing electrically heated vehicles-windshield.
