离心压缩机和各类风机是冶金生产中的关键设备,它们的故障停机往往会影响整个钢铁生产过程。这类设备的转速高、安装精度要求高、检修难度大。如何管好用好这类设备,确保生产和设备的安全,是冶金企业普遍关心的一个问题。目前国外一些技术先进的钢铁企业逐步采用状态监测和故障诊断技术来管理设备,并已获得明显的经济效益。 Centrifugal compressors and various blowers are the key equipment in metallurgical production and their downtime often affects the entire steel production process. Such equipment, high speed, high precision installation, maintenance difficult. How to manage such equipment well and ensure the safety of production and equipment is a common concern of metallurgical enterprises. At present, some advanced steel enterprises in foreign countries gradually adopt condition monitoring and fault diagnosis technologies to manage their equipment and have obtained obvious economic benefits.
