Fluid supply system and method of controlling fluid supply system |
摘要 |
A fluid supply system includes a tank, a shutoff valve, a fluid fill channel, a fluid supply channel, a fill detector, a pressure detector, and a controller. The shutoff valve includes a shared channel to enable fluid to flow from a fill hole to the tank and to flow from the tank to a fluid usage device. The pressure detector is provided in the fluid supply channel. The controller is configured to output a close instruction to the shutoff valve and configured to execute a processing to determine open valve malfunctions in the shutoff valve based on changes in pressure values which are input from the pressure detector. The controller stops the processing to determine open valve malfunctions when the fill detector detects that the fluid supply system is in the supplying state. |

1. A fluid supply system comprising:
a tank to store a fluid, the fluid being changeable in volume in accordance with a change in pressure; a shutoff valve provided in a port of the tank, the shutoff valve including a shared channel to enable fluid to flow from a fill hole to the tank and to flow from the tank to a fluid usage device; a fluid fill channel including one end connected to the shared channel and another end connected to the fill hole; a fluid supply channel including one end connected to the shared channel and another end connected to the fluid usage device; a fill detector configured to detect that the fluid supply system is in a supplying state in which fluid is to be supplied to the tank via the fluid fill channel; a pressure detector provided in the fluid supply channel; and a controller configured to output a close instruction to the shutoff valve and configured to execute a processing to determine open valve malfunctions in the shutoff valve based on changes in pressure values which are input from the pressure detector, the controller stopping the processing to determine open valve malfunctions when the fill detector detects that the fluid supply system is in the supplying state. |
