隔舱传动装置适用于运送原油、石油及化学液体的船舶的泵轴以及其它通过机舱水密舱壁处的轴系。
1、隔舱壁密封装置为一圆环状设备，主要由两组填料函和端面密封机构组合而成。通过填料函、壳体、哈夫式密封环、O型圈、之间有效的机械结合，能够在江河和海洋上各种中、小型船舶上通用.它安装在船舶主轴上并固定在舱壁上，可作为船舶轴系贯穿舱与舱之间的密封，特别在特殊情况下通过O型圈与哈夫式密封作用，在任一舱内进水一定程度后，可以实现隔舱之间的自动补偿密封。
2、主船体在设计和建造时按要求设置了若干的横向和纵向舱壁，这些舱壁所起的作用归纳起来有如下几个方面：将船体内部分隔成若干个舱室，以便安装各种机械设备及装载货物、燃油、淡水、备品和压载水等；横舱壁对保证船体的横向强度和刚性起很大作用，它是船底、舷侧和甲板等结构的支座，可使船体各部位构件之间的作用力相互传递，其中水密横舱壁是保证船舶抗沉性能的重要结构；纵舱壁可减少自由液面对船舶稳性的影响，较长的纵舱壁还可增强船舶的总纵强度；某些舱壁采用了防火结构，可在一定时间内防止火灾蔓延.舱壁一般按用途和结构形式的不同分两大类。

The bay driving  device is the marine pump spindle which can carry crude oil, petroleum and chemical liquid ,and it is  also other shafting which passes water-tight bulkhead of the cabin.

1.     Bulkhead sealing device is a circular ring equipment and mainly consists of two sets of stuffing boxes and end face sealing mechanism. By the effective  and mechanical combination of stuffing boxes, housing, half type sealing ring, o-type ring,  can it be employed universally in various medium-size and small-size ships running in the rivers and seas. It is installed in the marine spindle and fixed in the bulkhead, serving as the seal between the cabins, especially in case of emergency, with the function of o-type ring and half-type sealing, it can realize the function of auto-compensation seal  between bays after any bay takes in water to some extent.

2.     When the main hull is under design and construction, some horizontal and vertical bulkheads are set up on it. The bulkheads have functions as follows: to divide the hull house into some cabins in order to mount various mechanical equipments and load cargos, fuel oil, fresh water, spares and ballast water ,etc. Transverse bulkhead is the support for the structure such as hull bottom, side and the deck, etc, playing a great role in the cross strength and rigidity of the hull. It also makes each parts of the hull transmit acting force. Transverse watertight bulkhead is an important structure which ensures the anti-sinking performance of the ship. Longitudinal bulkhead can reduce the impact free water surface imposes on the stability of the ship. Even longer ones can enhance the total longitudinal strength of the ship. Fireproof structures are applied on the some bulkheads to prevent the spreading of the fire in a given time. Generally speaking, the bulkhead can be divided into two groups according to the purpose and structural style.
