Abstract
A power supply control device of a nitrogen gas generator includes: a pipe having a nitrogen gas inlet for receiving input of nitrogen gas from a nitrogen gas generator that compresses air by a compressor to separate the nitrogen gas from the air, and a nitrogen gas outlet for outputting, to outside, the nitrogen gas received by the nitrogen gas inlet; a pressure gauge that measures pressure inside the pipe; a flowmeter that measures a flow rate of the nitrogen gas flowing inside the pipe; and a control unit that controls supply of power to the compressor and shut-off of the supply of the power in accordance with a measurement result of at least one of the pressure gauge and the flowmeter.
Claims10
A power supply control device for a nitrogen gas generator that compresses air by a compressor to separate a nitrogen gas from air, the power supply control device comprising:
- a pipe having:
- (a) a nitrogen gas inlet configured to receive a nitrogen gas from the nitrogen gas generator, and (b) a nitrogen gas outlet configured to output the nitrogen gas received by the nitrogen gas inlet outside the power supply control device;
- a control valve provided on a flow passage of the pipe between the nitrogen gas inlet and the nitrogen gas outlet;
- a pressure gauge configured to measure a pressure inside the pipe between the nitrogen gas inlet and the control valve;
- a flowmeter configured to measure a flow rate of the nitrogen gas flowing inside the pipe between the nitrogen gas inlet and the control valve;
- and
- a processor programmed to:
- control an amount of power supplied to the compressor and shutting off the supply of the power in accordance with a measurement result of at least one of the pressure gauge and the flowmeter, and
- open the control valve in a case where a flow of the nitrogen gas inside the pipe is not detected based on the flow rate measured by the flowmeter.
