一般舱底水吸口分:支吸口(branch bilge suction),直吸口(direct bilge suction)和应急吸口(emergency bilge suction)没有所谓的独立吸口,我猜楼主的独立吸口是不是指的直接吸口
支吸口要接在舱底水总管上的,
直吸口是直接接舱底泵的
应急吸口是接机舱里排量最大的泵,一般接冷却水泵,用于破舱紧急使用的。
对于机舱而言,就bv的规范分两种情况:
1.底板如果是以一定角度倾斜至中线,要一个支吸口和一个直吸口这两个吸口位于中线处,以及一个应急吸口
2.底板是平的,在每边要一个支吸口和一个直吸口以及一个应急吸口
如果是尾机型,吸口一般位于首部和尾部的两侧,除了形状的无法实现,在尾部每一侧有吸口

In Propulsion machinery spaces, bilge suction are to include:
In propulsion machinery spaces, bilge suction are to
include:
• where the bottom of the space, bottom plating or top
of the double bottom slope down to the centreline
by more than 5°, at least two centreline suction, i.e.
one branch bilge suction and one direct suction, or
• where the bottom of the space is horizontal or
slopes down to the sides, at least two suction, i.e.
one branch bilge suction and one direct suction, on
each side, and
• one emergency bilge suction.
b) If the tank top is of a particular design or shows discontinuity,
additional suction may be required.
c) Where the propulsion machinery space is located aft,
suction are normally to be provided on each side at the
fore end and, except where not practicable due to the
shape of the space, on each side at the aft end of the
space.
d) In electrically propelled ships, provision is to be made
to prevent accumulation of water under electric generators
and motors. |
