发布时间：2019-05-05 10:46
【摘要】：离心式压缩机日常运行过程中非常典型的故障就是由于机组振动而引起的机械故障。机组振动轻则会缩短压缩机运行时间、减少压缩机运行寿命甚至装置非计划停工,造成非必要经济损失,重则压缩机部件损坏或人身伤害事故而造成重大经济损失。鉴于振动故障对压缩机日常运行的严重危害性,必须对离心式压缩机的振动原因及特征进行深入分析,对产生机组振动的机理要进行深入的研究,探索出能够准确判断振动故障的方法,不断总结经验,从而指导压缩机的工艺操作、日常检修及维护保养,避免或减少振动故障的发生。 本文通过对三种型号压缩机三种故障现象进行系统分析,针对叶轮断裂、可倾瓦块设计缺陷、低频振动三种故障现象,从理论上对故障现象进行详细分析,并对叶轮强度进行建模校核,采用理论与实践相结合的办法,对相应的故障现象进行检修处理,达到了一定效果,对今后同类型振动故障提供了一些处理思路和方法。
[Abstract]:The typical failure of centrifugal compressor in daily operation is the mechanical fault caused by the vibration of the unit. The light vibration of the unit will shorten the running time of the compressor, reduce the service life of the compressor and even the unplanned shutdown of the unit, resulting in unnecessary economic losses, heavy damage to the compressor components or personal injury, resulting in significant economic losses. In view of the serious harm of vibration fault to the daily operation of compressor, the vibration reasons and characteristics of centrifugal compressor must be deeply analyzed, and the mechanism of generating unit vibration should be deeply studied. In order to guide the process operation, daily maintenance and maintenance of compressor, the vibration failure can be avoided or reduced by exploring the method of accurately judging the vibration fault and summarizing the experience constantly, so as to guide the process operation, daily maintenance and maintenance of the compressor. Based on the systematic analysis of three kinds of fault phenomena of three types of compressors, this paper analyzes in detail three kinds of fault phenomena, such as impeller fracture, design defect of tilting tile block, low frequency vibration, and so on, according to the breakdown of impeller, design defect of tilting tile block and low frequency vibration. With the method of combining theory and practice, the corresponding fault phenomena are overhauled and treated, and some results are achieved. Some ideas and methods for dealing with the same type of vibration faults in the future are provided.
