ANALYSIS ON HIGH TEMPERATURE OCCURRED ON THRUST BEARING BUSH IN CENTRIFUGAL COMPRESSOR AND IMPROVEMENT

Zhang Wei;Xu Xinjin;Xie Huiwu;PetroChina Daqing Petrochemical Co.;  
The reasons for high temperature occurred on thrust bearing bush in centrifugal compressor were studied. To get the minimum deformation of membrane under heat condition, the pre-tensioning strength on coupling should be calculated, which might be increased or decreased according to practical conditions to assure the bush temperature in a normal range.
