Air pressure is used inside the ship for starting the main engine and auxiliary machines, controlling the onboard equipment, and so on. Since it has a large high-pressure reservoir tank, compressed air can be used even during a power outage. When a power failure occurs, the electrically driven fuel oil supply pump and fuel oil circulation pump stop, and the pressure of the fuel oil supply pipe that supplies fuel to each diesel generator decreases. Since the pneumatic pump can obtain a discharge pressure commensurate with the working air pressure, during normal operation, if a slightly lower air pressure is applied to the pneumatic pump through the working air pressure regulator by the pressure of the fuel oil supply pipe, the air The operation pump does not operate, and light fuel oil does not flow into the fuel oil supply pipe. However, if the pressure in the fuel oil supply pipe drops during a power outage as described above, the pneumatically operated pump automatically operates and sends light fuel oil to the fuel oil supply pipe, so that the diesel generator continues to operate even after a power outage. You can drive.
