摘要： A method for isolating a leak in a closed-volume liquid system comprises circulating a fluid through a plurality of isolatable zones and a non-isolatable zone in a closed-volume liquid system, detecting a leak in the closed-volume liquid system, isolating all of the isolatable zones from the non-isolatable zone, sequentially detecting if the leak is present in the non-isolatable zone and each of isolatable zones, and taking corrective action after the leak is detected.

摘要： A method for detecting a leak in a closed-volume liquid system comprises circulating a fluid through a closed-loop with a pump having a reservoir and that is driven by an electric motor. The method also comprises sensing a pressure in the closed-loop, sensing current draw by the motor and sensing fluid level in the reservoir. The method further comprises determining a presence of a leak of fluid from the closed-loop based upon two of the sensed signals using a first leak detection logic, and determining the presence of a leak of fluid from the closed-loop based upon at least one of the sensed signals using a second leak detection logic.

摘要： A fluid system comprises a pressure vessel with a baffle oriented at a skew angle. The baffle divides the vessel into first and second volumes. A first port is provided to introduce a pressurizing fluid into the first volume, and a second port is provided to circulate a working fluid within the second volume. A purge aperture is provided to purge the pressurizing fluid from the second volume across the baffle into the first volume, and a flow aperture is provided to transfer the working fluid through the baffle between the first and second volumes.
