弯管用多相流冲蚀磨损试验机设计与研究

Design and Research of Multiphase Flow Erosion and Wear Tester for Bend Pipe

为了研究弯管的冲蚀磨损机理,设计了一台弯管用多相流冲蚀磨损试验机,该试验机主要由冲蚀单元、混合单元、动力单元和管路单元四部分组成。其中,冲蚀单元设计有4个独立夹具,能同时对4个弯管试件进行多相流且不同工况条件试验;管路单元设计有回流管,能使冲蚀介质冲蚀试验结束后流回混合单元,实现流体循环利用。最后通过理论计算及仿真分析对试验机易损管路进行了校核,确保该试验机满足设计要求。

In order to study the erosion and wear mechanism of bend pipe,a multiphase flow erosion and wear testing machine was designed,which includes erosion unit,mixing unit,power unit and pipeline unit.The erosion unit is designed with four independent fixtures,which can be used simultaneously.The four elbow test pieces are tested for multiphase flow and different working conditions.The pipeline unit is designed with a return pipe,which can make the erosion medium flow back to the mixing unit after the erosion test is completed,and realize the fluid recycling.Finally,through theoretical calculation and simulation analysis,the vulnerable pipeline of the testing machine is checked to ensure that the testing machine meets the design requirements.
