Causes of Vibration Exceedance of Cyclone Separator and Pipeline and Its Modification
The cyclone separator and connecting piping of the circulating system in the polyester plant of a petrochemical company had excessive vibration problems during operation.In order to completely solve the excessive vibration problem of this equipment,flow field simulation and structural stress analysis were carried out on the cyclone separator in combination with the operation principle of the equipment,the results of the on-site investigation and the vibration test data,and practical modification measures were proposed.After the modification,the maximum stress value is greatly reduced compared to the pre-improvement period,and at the same time,it is ensured that the maximum stress point occurs to avoid the stress concentration area.In the rated working condition,the vibration data of the vibration source is reduced by 98％,which completely solves the problem of excessive vibration of the cyclone separator,and makes the plant start smoothly,which buys time for the enterprise and creates benefits.
