However, even in this case, there are limits to the inclination of the propeller shaft due to the expansion of the engine room and the impact on propulsion.
There is a problem that a suitable vertical distance cannot be maintained.

The upper part is covered by an inner bottom plate 9. Further, in the longitudinal direction of the ship inside the condensate tank 17, the plurality of reinforcing plates 15 are respectively extended from the bottom surface of the condensate tank 17 to the inner bottom plate 9. Each reinforcing plate 15 has an appropriate number of holes in the vertical and lateral directions of the ship, and the condensate tank 17
The condensed water stored inside can be circulated.

The tip of a condensate drop pipe 19 connected to the marine condenser 1A is provided. On the other hand, a condensate pump 21 is disposed inside the condensate tank 17 on the forward side of the ship, and an inlet 25 of the condensate pump 21 equipped with an impeller 23 is located at the lower end inside the condensate tank 17. Further, the discharge port of the condensate pump 21 is connected to the pump discharge pipe 7.
次に作用を説明する。 Next, the effect will be explained.

引され、ポンプ吐出管７に移送される。 Condensed water from the marine condenser 1A passes through a condensate drop pipe 19 and is stored in a condensate tank 17. Condensed water in the condensate tank 7 passes through a hole formed in the reinforcing plate 15, is sucked from the suction port 25 of the condensate pump 21, and is transferred to the pump discharge pipe 7.

The condensate pump 21
The value of the necessary suction head that determines the effective suction head of the water can be reduced, and therefore suction and transfer by the condensate pump 21 can be made more suitable.

きる。 Further, a reinforcing plate 15 is disposed inside the condensate tank 17, and the condensate tank 17 is connected to the inner bottom plate 19 and the bottom outer plate 1.
Since the depth of the condensate tank 17 can be made as close to the bottom shell plating 13 as possible due to construction, the condensate tank 17 can be buried as close to the bottom shell plate 13 as possible, and therefore The suction port 25 of the pump 21 can be set near the bottom shell plate 13. Therefore, the distance between the water level of the stored condensed water and the suction port 25 can be set large, and the effective suction bed of the condensate pump 21 becomes large, so that suction and transfer by the condensate pump 21 can be suitably performed. be able to.
更に、有効吸込ヘツドを必要以上に大きく設定

Therefore, the distance between
The position of the marine condenser 1A can be lowered, the engine room can be reduced, and the propulsive force can be improved.
