摘要
为提高综合测试台的测试性能,满足烟草行业新标准的技术要求,对综合测试台的吸阻/压降测量单元进行了优化改进.自控系统中将控制气路和测量气路分开,采用阀岛技术集中控制气路并替代复杂的电控部件;增加自动气路清洁系统,避免掉落烟丝对气路环境产生影响;分析了抽吸管路对吸阻测定的影响规律,并调整了抽吸管路长度.选用不同标称值的标准滤棒和同一品牌和规格的卷烟进行了吸阻对比测定.结果表明：改进前后标准滤棒吸阻的RSD由0.10％～0.47％降低到0～0.04％,测量相对误差由0.53％ ～ 0.90％降低到0～ 0.49％;卷烟吸阻的RSD由4.287％～6.911％降低到2.663％～4.024％.改进后综合测试台可以满足行业标准要求,有效提高了吸阻测量的稳定性及准确性.
To improve the performance of the test station and meet the technical requirements of new tobacco industrial standards,the draw resistance/pressure drop measurement unit in the test station was optimized as following：separating the air circuit for control from that for measurement in the automatic control system; instead of the complex electronic control units,valve-island technology was used to control air circuit centrally; adding automatic air cleaning system to prevent the dropped tobacco from influencing the air circuit; adjusting the length of suction pipe by analyzing the rule of draw resistance measurement affected by suction pipe.A comparative measurement of draw resistance was conducted with a set of standard filter rods of different ratings and the cigarettes of same brand and specifications.The result showed that after improvement,the RSD of draw resistance of standard filter rods decreased from 0.10％-0.47％ to 0-0.04％,the relative error of measurement decreased from 0.53％-0.90％ to 0-0.49％; and the RSD of draw resistance of cigarettes decreased from 4.287％-6.911％ to 2.663％-4.024％.The improved test station improves the stability and accuracy of draw resistance measurement effectively.
