AIR SUPPLYING DEVICE OF AIR LUBRICATION TYPE SHIP

摘要

PROBLEM TO BE SOLVED: To provide an air supplying device of an air lubrication type ship which boosts the pressure of pressurized air and jets the same coping with fluctuations in pressurized air pressure and draft pressure, even when the pressurized air pressure supplied to the main engine by a supercharger fluctuates by the output of the main engine and the draft pressure fluctuates according to a loading state, and has high energy efficiency improving energy saving effect.

SOLUTION: The air supplying device includes: the supercharger 10 supplying the pressurized air to the main engine 6 of the air lubrication type ship; an extraction means extracting part of the pressurized air; a boosting means 30a further boosting the pressure of the pressurized air extracted by the extraction means; a booster passage 41a supplying the pressure-boosted air boosted by the boosting means 30a; a bypass route 51 bypassing the boosting means 30a; and a route selection means selecting the booster passage 41a and the bypass route 51. The booster passage 41a and/or the bypass route 51 are/is selected by the route selection means, and the pressure-boosted air and/or the pressurized air are/is supplied and jetted around a hull.
