摘要

Topic Method and the device in order to remove the fact that the dust invades the seal outside the seal system of the axis which penetrates the hull of the boat for maritime affairs are offered.Solutions When in the water of the shoal advancing, there are times when the seal outside the propeller shaft wears by the underwater substance, but in this case, wear rate of friction material of the seal are times when suitable quickly it advances. With this invention, the flow where the seal outside nearly increase of the filtrate water is put out to immediately from the water source inside the boat is sent. Effectively, through the nozzle ring which is adjusted to the axis it does. According to need, increase making the water heat which comes out, causing correct pressure outside the seal, it is possible to react when from the bearing a leak of oil occurs around.
