The Failure Diagnosis And Analysis Of Styrene Screw Compressor

Along with screw compressor technology development,The screw compressor more and more widespread is applied in the chemical industry.At present,the double screw compressor is one of main gas booster compressor in our country pereoleum chemical industry. As process units key equipment its running status stability direct relation entire process units security,stability.Once the equipment breaks down,that will have the possibility to cause the entire process units steady operation and to create the equipment comprehensive stop,reduces the production efficiency seriously and brings the huge ecomomic loss.From the 80s,our country department concerned the condition monitor and the failure diagnosis technology research to the screw compressor,causes the monitor and the failure diagnosis technology level enhances rapidly of our country's screw compressor.The mechanical device failure diagnosis technology's important meaning it to lay the foundation for the mechanical device tradition service system's reform,might cause the reasonable foreknowledge service system to replace traditional the fixed time service system,thus the reduced accident formation rate,reduced the maintenance cost,guaranteed mechanical device's safe operation.This topic take Daqing petrochemical company 3th factory styrene worksshop's double screw compressor failure diagnosis and the analysis as the research background,carries on the condition monitor and the failure diagnosis of the double screw compressor,is for the purpose of seeking for the inner link between the analysis examination system and the breakdown,discovered promptly the breakdown and the prevention malignant accident occurs,guaranteed crucial equipment complete and normal work,eliminates the chance failure stop effectively.The practice proved that as a result of the condition monitor technology's application,causes suddenly accident's formation rate to reduce greatly,and so on management expense,maintenance cost reduces large scale,thus sharpened the compressor continuous working ability,to equipment steady operation very good safeguard function.This article introduction to the double screw compressor's basic composition structure,the principle of work,the essential feature as well as the domestic and foreign double screw compressor failure diagnosis aspect's present situation has carried on the summary.Then has carried on the outline to the equipment failure diagnosis technology,through carries on the feature extraction to the screw compressor common breakdown's characteristic,had expounded with emphasis the screw compressor rotor and the bearing and so on which the breakdown form,characteristic as well as mechanism of production,and proposes the related vibration diagnosis method.This article gave the screw compressor's vibration test technology and concrete analysis system,finally through carried on the diagnosis and the analysis to the scene concrete breakdown case,has manifested the failure diagnosis technology in the production practice function.
