The nonuniform abrasion failure and high-temperature thermal failure of packing rings have a significant influence on compressor reliability, particularly that of oil-free compressors.

In this study, a test rig was constructed to measure the dynamic temperature of packing rings under different operational conditions in an oil-free reciprocating compressor.

The dynamic axial and radial temperature distributions of the packing rings were obtained using an innovative internal temperature testing device that kept the thermocouples and packing box relatively static during compressor operation.

A three-dimensional heat transfer model was also developed to analyze the temperature distribution of the packing boxes, piston rod, and cylinder during such operation.

Good agreement was observed between the simulation results and experimental data, which showed an average relative error of less than 2.35%.

The results indicate that the pressure ratio exerts a significant effect on the axial temperature distribution and determines which packing ring reaches the maximum temperature.

They also show the average temperature to rise with an increase in the rotational speed and to fall with an improvement in the external cooling conditions.

Finally, the material of the packing rings was found to affect the temperature gradient from their inner to outer surface.
