摘要
针对合成氨装置氨冰机组在运行中高压缸转子振值过高的问题,利用本特利设备监测诊断平台,对该机组进行状态监测,根据频谱图、波德图、频谱趋势图和瀑布图,归纳出振动特征。结合检修情况,应用设备故障诊断技术判断检修前、后振值高的原因均为振值失真,原因是探头监测的表面有镀层和光洁度不合格。
In a synthetic ammonia plant, the vibration value of rotor in high pressure cylinder in refrigerating unit was too high. The Bentley monitoring and diagnosis platform was used to find out the vibration performance by spectrum diagram, Bode diagram, spectrum chart and waterfall. By application of equipment failure diagnosis technology, it＇s determined that high vibration value before and ＇after maintenance was caused by vibration value distortion, which was also verified during maintenance, whereas the distortion was caused by unqualified finish of coating surface at which the prober once aimed.
