Fluid supply system

A fluid supply system comprising:

• a centrifugal pump;
• an inlet shut-off valve provided upstream of the centrifugal pump and configured to allow or shut off an inflow of a fuel into the centrifugal pump by opening and closing;
• a starting pump that is connected to the centrifugal pump in series, is provided downstream of the centrifugal pump, and has a discharge flow rate less than that of the centrifugal pump;
• a measuring valve that is provided downstream of the centrifugal pump and the starting pump, measures an amount of fluid discharged from the centrifugal pump or the starting pump, and discharges the fluid to a downstream each time the fluid reaches a predetermined flow amount;
• a differential pressure valve that is provided downstream of the centrifugal pump and the starting pump, and is driven based on a differential pressure between an upstream pressure and a downstream pressure of the measuring valve;
• and
• a flow rate control valve that is provided downstream of the centrifugal pump and upstream of the differential pressure valve and has a valve opening speed that is set slower than that of the differential pressure valve,
• wherein the valve opening speed of the flow rate control valve is 1/5 to 1/10 of the valve opening speed of the differential pressure valve.
