摘要：干式喷房的纸盒在随着吸附率的不断提高，纸盒的风阻也逐渐增大，按照以往的送排风结构，喷房各区统一排风，纸盒吸附率高的区域，风量减少，导致喷房各区的风不平衡。广汽本田三工厂涂装车间上涂B线在导入干式喷房前进行了风平衡的探索分析，从喷房分区设计、喷房结构、风压检测、排风风机频率自动调节等方面进行改进，稳定了纸盒式干式喷房各区域的风平衡，为其他整车厂提供了成功实践案例。

Abstract： With the continuous improvement of the adsorption rate of the dry spray booth， the wind resistance of the cartons also gradually increases. According to the previous air supply and exhaust structure， all areas of the spray booth are exhausted uniformly， and the areas with high carton adsorption rates， The decrease in air volume results in unbalanced wind in all areas of the spray booth. The coating line B of the paint shop of the third plant of Guangqi Honda carried out an exploration and analysis of wind balance before it was introduced into the dry spray booth. Improvements were made in the area of spray booth design， spray booth structure， wind pressure detection， automatic adjustment of exhaust fan frequency， etc. ， Stabilized the wind balance in each area of the carton dry spray booth， and provided successful practical cases for other automakers.

汽车整车涂装线喷房，传统的方式是湿式喷房，目前开始逐步探索和应用各种干式喷房，最新技术为纸盒式干式喷房，在各大主流汽车厂都在尝试使用。干式喷房纸盒形式不一：迷宫式、蜂窝式、导流板+过滤棒形式等，不同的形式，在结构与捕漆效率上略有不同。纸盒漆渣的积聚会增大纸盒的风阻，风机风量一定的情况下，纸盒上的漆渣越多，风阻就越大，影响通过纸盒的风量与风速，进而影响喷房的风速及风平衡。喷房各区排风量与原设定值差异变大时，在送风量不变的情况下，排风量变小的区段的风会流向旁边的区段，导致风平衡出现异常，漆雾跟着风飘向其他区段，导致车身的上漆情况受到影响，特别是喷不同颜色的车时，容易造成漆面污染，进而影响喷涂品质。喷房喷涂区域的风平衡与车身漆面品质息息相关。……
