纺织生产过程数据集成与处理系统的开发

基于现场总线技术开发纺织生产全过程的底层数据采集及处理系统。系统底层网络由多个PROFIBUS总线网络和其他子网组成,实时采集纺织生产过程所有工序中各设备的重要参数;上层基于工业以太网和WinCC设计,完成对海量信息的集成和处理。经实践,认为:该系统运行稳定可靠,可实现470多台设备40 000多个底层数据的实时采集处理、在线故障诊断及报警,可对整个纺织生产过程进行集中监控和管理。

Increasing the Energy Efficiency of Air Jet Weaving Based on a Novel Method to Exploit Energy Savings Potentials in Production Processes of the Textile Industry

This article deals with the energy efficiency of textile weaving machines. A method based on exergy balances has been developed at the Institute for Textile Technology RWTH Aachen University （ITA）, Aachen, Germany in order to improve energy efficiency textile machines. The relay nozzles of the air-jet weaving technology need up to 80% of the energy of the weaving machine. At ITA, a new nozzle concept was developed. The developed geometry is a so called High-Volume-Low-Pressure nozzle （HVLP nozzle）, based on convergent nozzle aerodynamic theory. With this concept, energy savings up to 30% are possible.
