| Summary: | In this study, an experimental study of the axial force on twin-screw compressor rotors was conducted to improve operating reliability. The variations in the axial force under different operating conditions and built-in volume ratios were investigated. Furthermore, the axial force of the end face was also calculated by employing the mean pressure model and sector pressure model and was compared with the experimental results. It was concluded that the sector pressure model is more accurate for predicting the axial force on the rotors in comparison with the mean pressure model. However, the mean pressure model was more accurate under operating conditions with a large built-in volume ratio. Moreover, the built-in volume ratio was found to have a larger influence on the axial force of the rotor end face than that on the rotor helical surface, where the former is approximately 50% larger than the latter. |
