The Study of the Test-control System for Multiphase Flow Test Stand

In this paper,through head loss calculation and analysis,some problems which occurred in the existing test stand were pointed out.A preliminary design of piping circuit of this test stand reconstruction was put out.Several improvements of stand control system will be done.Finally the analysis of test errors of this stand had been carried out,and the test parameters were determined.The total error of the model acceptance test,test head and the Reyolds number for the performance test will be met the relevant regulations.After reconstruction,the head losses in the circuit will be reduced greatly.So the max.test head and max.test discharge will be increased.Through the further automatization of the measuring system and improvement of data processing system,the test accuracy of this stand will be enhanced.
