校车淋雨试验解决方案

所属分类：app江南

方案目的

检测校车在降雨环境下的外壳密封防雨性能。

方案简介

本试验方案主要包括：侧面和顶部喷淋系统、补水系统、水循环系统、排污系统、电控系统等五个部分。防雨密封性试验装置要保证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。所有参数参照QCT476—2007标准进行淋雨设计和试验。

校车淋雨试验方案-参考图

【喷淋系统】整个淋雨房体喷淋系统主要由管路、喷嘴、阀门、过滤器、水泵、显示装置等组成。全部喷淋管道材料采用不锈钢管，

【淋雨强度】顶部平均为12±1mm/min,两侧面为平均8±1mm/min（喷嘴喷射压力:170kPa±30 kPa）。

【过滤系统】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。

【补水系统】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。

1．进水管采用DN32镀锌管保证供水量。

2．在补水管末端设置浮球式机械开关装置，当补水达到设定的最高液面时，机械装置关闭补水管

【控制系统】采用PLC控制+控制面板控制和远程摇控器控制，配有电参表，带断电数据保存功能及报警提示。

方案价值

该方案根据一般校车车身尺寸量身定制，可完整的检测校车的外壳防雨性能。对于提升校车的品质有着重要作用。该方案采用自动过滤补水系统，保证淋雨过程中有不断的水源供应，可加快检测进度。淋雨检测试验可保证校车的出厂合格率，降低校车在雨天行进中可能潜在的安全风险，这对保障学生们的人身安全有着重要意义。
