Continuous Constant-Flow Accumulator Power Unit Test Bench

When the test subject or load requires a constant flow rate, an accumulator system capable of delivering high instantaneous flow is employed, with its transient output flow precisely controlled. By monitoring the liquid level within the accumulator and performing specialized fluid‑mechanics‑based compensation calculations—either to determine the instantaneous flow rate or by comparing it with the flow signal acquired from the drain line—a stable and accurate flow‑control reference signal is generated. This signal, combined with Xiwel’s comprehensive flow‑servo control system, enables highly precise, steady‑state flow delivery to the load or test object.
