当采用状态监测维修时,维修及故障造成的停机时间和维修费用都将大幅度下降。 据考察,美国洛杉矶和旧金山有两家炼油厂从70年代起就推行状态监测维修制,一般透平压缩机组6～7年才解体一次;许多装置3～4年才大修一次,取得了明显的经济效益、他们的主要做法是推广状态监测及诊断技术,在技术经理(或总工程师)领导下有专门负责可靠性的工程师,下设有检测人员,定期巡检,建立设备状态数据库,实行状态监测维修。 一、逐步实行状态监测维修的设想 目前,辽化采用振动分析方法于转动机械状态监测和诊断方面已具备一定基础,并开始
When condition monitoring is used, maintenance downtime and maintenance costs due to repairs and malfunctions are significantly reduced. According to the survey, two refineries in Los Angeles and San Francisco of the United States have implemented condition monitoring and maintenance systems since the 1970s. Generally, turbine compressor units have only been dismantled once in six to seven years. Many devices have been overhauled in three to four years and have achieved obvious Economic benefits, their main approach is to promote condition monitoring and diagnosis technology, under the leadership of the technical manager (or chief engineer) has a special responsible for the reliability of the engineers, under the inspection staff, regular inspection, the establishment of equipment status database, the implementation of the state Monitoring and maintenance. First, the gradual implementation of the status of the idea of monitoring and maintenance At present, the use of vibration analysis of Liaoyang method of rotation in the mechanical condition monitoring and diagnosis has a certain basis, and began
