来自BTG的Florent Bougerolle与TWM讨论了刮刀振动监测系统如何帮助卫生纸生产商洞察昂贵的涂层破环和扬克缸振动。扬克缸因振动导致的维修会产生比较大的经济损失。问题重重的扬克缸平均每年都要重磨一次,重磨时转速降低,影响连续生产。刮刀振动监测系统是用来追踪危险工况和预测振动产生的常用方法,尽管其有效性受到采集的数据和分析方法的制约。本文回顾了振动的基本原理,阐述了振动充分测量和分析的原理,并对用户的振动监测系统改进给出了建议。1测量和正确表征振动众所周知,震颤来自于烘缸表面与起皱或清洁刮刀摩擦产生的振动。振动受多个工艺因素影响,振动的结果表现为一系列0~20k H z范围的临界频率。采用频闪灯光和
Florent Bougerolle from BTG discussed with TWM how blade vibration monitoring systems can help tissue manufacturers gain insight into expensive coating breakdowns and Yankee jar vibrations. Yankee cylinder due to vibration caused by maintenance will have a greater economic loss. The Yankee problem-solving is regrouped on an average every year, and the speed is reduced when it is refurbished, affecting continuous production. The scraper vibration monitoring system is a common method used to track hazardous conditions and predict the generation of vibrations, although their effectiveness is governed by the data and analytical methods collected. This paper reviews the basic principle of vibration, expounds the principle of full vibration measurement and analysis, and gives some suggestions for improving the vibration monitoring system of users. 1 Measurement and Correct Characterization of Vibrations It is well-known that tremors result from the friction between the dryer surface and the creping or cleaning blade. Vibration is influenced by several process factors, and the vibration results appear as a series of critical frequencies in the 0 to 20 kHz range. Using strobe light and
