Summary

In order to verify the reliability and utility of the multi-column compound profile theory, a couple of designed multicolumn compound profile meshing pairs are applied in an oil-flooded single screw compressor as the experimental prototype, then the prototype runs 2000 hours continuously in the experimental platform, and the displacement is detected. Results show that the prototype has a steady displacement, and the energy efficiency grade is very close to the best grade. This proves that the new pair has a good sealing performance. A comparative observation on the star wheel tooth flanks are conducted at the end of test, and the results demonstrate that the nodular cast iron star wheel with multi-column compound profile has a high wear resistant property and a good hydrodynamic lubrication characteristic. This result also demonstrate that the nodular cast iron can be used to make star wheel to reduce the cost of single screw compressor instead of the expensive PEEK material.
