Failure Analysis and Improvement of a Certain Type of Turbocharged Turbine Performance Test Platform

A new troubleshooting idea and improvement measures were put forward for the faults of a certain type of turbocharged turbine performance test platform. The influence of pipeline diameter on turbocharged turbine performance test results was verified by theoretical checking whether there were defects in equipment selection and pipeline design of the test platform, and the pipeline diameter was redesigned and improved according to the calculation results. The pipeline materials and layout of the inlet and outlet of the turbocharged turbine were analyzed, and new pipeline materials and reasonable layout of pressure sensors were adopted for the inlet and outlet of the turbocharged turbine. In addition, the experimental results show that the difference of atmospheric pressure in different regions was also one of the important factors affecting the performance of the test bed.Finally, the fault removal of the test bed was successfully achieved, and the effectiveness of the proposed improvement measures was verified through experiments.
