Abstract

Abstract

In this paper, the process level and injection flow rate during the accumulator discharge lines flow test are calculated with an iterative method, and the effectiveness of the test settings is evaluated against the results. It shows that the initial parameters chosen by the procedure are appropriate, and they can maintain the two check valves on the injection lines fully open.After the motor-operated valve is fully open, the injection time is still long enough for obtaining data to calculate the real flow resistance of the lines.
