【摘要】：離心式壓縮機日常運行過程中非常典型的故障就是由于機組振動而引起的機械故障。機組振動輕則會縮短壓縮機運行時間、減少壓縮機運行壽命甚至裝置非計劃停工,造成非必要經(jīng)濟損失,重則壓縮機部件損壞或人身傷害事故而造成重大經(jīng)濟損失。鑒于振動故障對壓縮機日常運行的嚴重危害性,必須對離心式壓縮機的振動原因及特征進行深入分析,對產(chǎn)生機組振動的機理要進行深入的研究,探索出能夠準確判斷振動故障的方法,不斷總結(jié)經(jīng)驗,從而指導(dǎo)壓縮機的工藝操作、日常檢修及維護保養(yǎng),避免或減少振動故障的發(fā)生。 本文通過對三種型號壓縮機三種故障現(xiàn)象進行系統(tǒng)分析,針對葉輪斷裂、可傾瓦塊設(shè)計缺陷、低頻振動三種故障現(xiàn)象,從理論上對故障現(xiàn)象進行詳細分析,并對葉輪強度進行建模校核,采用理論與實踐相結(jié)合的辦法,對相應(yīng)的故障現(xiàn)象進行檢修處理,達到了一定效果,對今后同類型振動故障提供了一些處理思路和方法。
[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.
