Self-driven Reciprocating High Pressure Stream Bubble Scour Devic

To overcome the technical problem of deposit in oil pipe,the high pressure bubble technology is employed.The structure of the anti-deposit device is the main factor to determine the efficiency.In the experiment,the conic nozzle is adopted,and the hydraulic model is established.First time,the bidirectional rotating nozzle driven by water stream is put forward,so the research of the nozzle will be developed to a new tendency.The 3D model of the virtual prototype is constructed to describe the basic configuration of the nozzle,and the possibility analysis is conducted.
