Research on Discharge Ports of Oil-Flooded Rotary Compressors

In the discha~&e p~ocess of a ~ota~y comp~esso~, the ~esistance of &as-oil two-phase flow th~ough the discha~ge po~t can't be i&no~ed.especially with oil-injected. The~efo~e, it's always an impo~tant p~oblem in this kind of comp~esso~ that the dischar&e po~t should be determined reasonably, design In this pape~. taking an oil-flooded single screw compressor as an example, developing a compute~ model, the effect of discha~ge port on the performance of an oil-flooded rotarY comp~esso~ has been analyzed in detail, also, the optimal outlet position under various working conditions have been presented.They have been proved by test in the end of the paper.
