                 Abstract: Taking 156 unit curing press of Double Coin Tire Chongqing Company as the research
             object, this paper puts forward a kind of drainage system modification based on liquid level detection and
             pneumatic control. This solution achieves precise discharge of condensate by removing traditional steam
             traps and introducing key components such as PLC automatic control system, stainless steel level tank, and
             pneumatic cut-off valve. After the renovation, the steam consumption has been reduced by 8.5%, resulting in
             an annual economic benefit of approximately 2 million yuan. In addition, the stability of the system has been
             significantly improved, while also achieving both economic and environmental benefits.

                                      全季轮胎“带飞”欧洲替换胎市场
                                  All season tire leads European replacement tire market growth

                 日前,欧洲轮胎和橡胶制造商协会(ETRMA)公布的数据显示,2025 年第一季度,欧洲消费者替换轮胎的
             销售量同比增长 3%,其中全季节轮胎的销量跃升 14%,引领了市场增长。
                 据欧洲轮胎和橡胶制造商协会秘书长亚当 . 麦卡锡称,始于 2024 年下半年的消费者轮胎市场复苏仍在持续,
             销售量现已接近 2019 年第一季度,即疫情影响前的水平。包括夏季、冬季和全季节乘用车轮胎在内的消费者轮
             胎需求在第一季度增至 5  870 万条,高于上一年同期的 5  730 万条。虽然夏季轮胎的销售量下降了 3%,但全季
             节轮胎市场保持了持续扩张,冬季轮胎的销售量同比增长 5%。
                 相比之下,卡车和客车轮胎的销售量下降了 4%,降至 270 万条,与 2019 年第一季度相比下降了 11%。欧
             洲轮胎和橡胶制造商协会将这一下降归因于经济和政治不确定性对需求产生的重大影响。
                 同样,农用轮胎的销售量同比也下降了 4%,降至 20.3 万条,扭转了自去年 3 月以来的增长趋势。欧洲轮胎
             和橡胶制造商协会指出,这一领域的销售量仍远低于疫情前的水平。
                 摩托车和踏板车轮胎的销售量同比增长 7%,达到 350 万条,不过麦卡锡指出,这是与疲软的 2024 年相比得
             出的结果。
