Study on the performance of pressure drop ratio about a new type of down-hole axial oil-water separation cyclone

An experimental investigation about the pressure drop ratio of down-hole axial oil-water separation cyclone was made.The result shows that the pressure drop ratio relied only on the split ratio instead of the inlet flow,oil content or the guide vane'structure.Besides,the relation between the pressure drop ratio and split ratio is exponential relationship rather than linear.The research results have an important significance to the design and automatic control when using in down-hole.
