货车淋雨试验方案

所属分类：app江南

设计目的

本试验室的试验目的主要是被试产品在淋雨条件下,产品防止雨水渗透的能力和遭到淋雨时或之后的防雨性能，主要检查车窗与天窗安装是否正常,密封性能是否可靠,安装方法是否正确。

方案简介

该测试方案设计参照《客车防雨密封性试验方法》GB/T 12480-1990及《客车防雨密封性限值及试验方法》QC/T476-2007。适用于检测汽车侧窗与天窗的水密封性，通过淋雨房多方位布局喷嘴，把淋雨检测的条件与外面自然状态相类似，来确认汽车的密封状态。淋雨试验房主要包括喷淋系统、补水系统、水循环系统、排污系统、电控系统等五大组成部分。

【淋雨试验区】从侧面和顶部方向对汽车窗喷水，避免出现喷水死角，保证喷水压力、流量对应于汽车各部位达到国标要求。淋雨房框架结构在保证防锈，防震的同时做到简洁美观，整个设备操作简单，便于零部件的检修和维护。

【降雨强度】顶部8-10mm/min,其余部位6-8mm/min（可调节）

【喷淋系统】采用可调节的塑料喷嘴。喷射状态为实心圆锥型，锥角为60度。喷水角度，顶部喷嘴与水平面垂直，喷嘴设计符合国家标准。喷嘴以方格阵列，喷淋面积内无空白区域。喷嘴可根据喷射角度作适当调整。

【过滤装置】在水池内安装两层过滤装置，可有效地过滤循环水池循环水中的杂质，减少喷嘴的堵塞，保证系统的正常工作。

【自动补水】为了及时给水池补水，特设计一套补水系统，补水系统由进水管、电磁阀、水位开关，球阀等组成。循环水池补水自动操作，减少工作量，加强系统运行的稳定性。

方案价值

该方案根据重型货车的尺寸重新设计，可满足整车完全淋雨的测试效果，检测车体的防水性能。该方案自带储水过滤系统，可加快检测速度，完成不间断的淋雨工作，突破了常规的日均检测数量。该方案还可通过调节降雨强度模拟不同的降雨环境，试验效果更加真实，同时能够检测整车对不同强度的防护能力，对于改善设计或工艺有着明显的帮助。经过淋雨检测的整车质量度得到保证，这也保证了司机和乘客的人身利益。
