Marine bulkhead gearing is suitable for transmission of power between airtight cabins of small and medium vessels.The bulkhead sealing device is mainly composed of two sets of packing boxes and a combination of end-face sealing types. Through the effective mechanical sequence combination between the packing box, shell, sealing ring, O-ring, and packing box, it can be widely used on various small and medium-sized ships in rivers and oceans. After being installed on the ship's main shaft and fixed on the cabin wall, it can be used as a seal for the ship's shaft system to penetrate between compartments. Especially in special cases, through the O-ring and Huff sealing effect, automatic compensation sealing between compartments can be implemented after a certain degree of water ingress in any compartment.
