Abstract
The invention relates to marine equipment, in particular to an improvement to a ship water-lubricated sealing device. A marine light-weight water-lubricated sealing device provided by the invention comprises a water-lubricated sealing seat which surrounds a rotating shaft and is fixedly installed on a ship body, a sealing end cover which surrounds the rotating shaft and is fixedly installed on the water-lubricated sealing seat, and a water-lubricated sealing ring. A static sealing end surface which is perpendicular to the rotating shaft is arranged on the sealing end cover. The water-lubricated sealing ring is placed in a space formed by the water-lubricated sealing seat and the sealing end cover, and is fixedly installed and wrapped on a sheath on the external surface of the rotating shaft. The static sealing end surface and the water-lubricated sealing ring form an end surface sealing pair. A sealing ring bush is installed between the water-lubricated sealing ring and the sheath. The marine light-weight water-lubricated sealing device has the advantages of light weight and small occupied space, and provides a technical guarantee for the quick navigation of ships.
Description
Technical field:
The present invention relates to shipborne equipment, relate in particular to the improvement of boats and ships water lubrication seal arrangement.
Background technique:
The water lubrication seal arrangement is one of boats and ships seal arrangement commonly used, is mainly used in stoping seawater to enter in the ship from the joint of ship stern tube shaft and shell, and the quality of its sealability directly has influence on the safe operation of boats and ships, is the important component part of boats and ships.Present boats and ships water lubrication seal arrangement comprise around running shaft and be fixedly mounted on the hull the water lubrication sealing seat and around running shaft and be fixedly mounted on end cover on the water lubrication sealing seat, and place the interior volume that water lubrication sealing seat and end cover surround and fixedly mount and encircle water lubrication seal ring on axle sleeve, the outer surface of the ring support of water lubrication seal ring encloses spring with firm being fixed on the axle sleeve of water lubrication seal ring around the spring of enclosing is arranged.Water lubrication seal ring and running shaft rotate synchronously, and end cover is provided with the static seal end face vertical with running shaft, and this static seal end face and water lubrication seal ring constitute the end face seal pair.The outer surface parcel of running shaft also is installed with sheath; sheath generally adopts the copper material of seawater corrosion resistance to make; avoid wearing and tearing and seawater corrosion with the protection running shaft; the outer surface of this sheath also wraps up and is installed with axle sleeve; axle sleeve generally adopts the stainless steel of seawater corrosion resistance to make; avoid wearing and tearing with the protection sheath, the wall thickness of axle sleeve is generally greater than 10 millimeters, and running shaft is provided with special device axle sleeve is fixedly mounted on the running shaft.Water lubrication seal ring and axle sleeve rotate synchronously during work, play seal action by the applying of water lubrication seal ring and static seal end face.The deficiency of this seal arrangement is that the quality of axle sleeve and optional equipment thereof is bigger, also needs additionally to increase length and the boats and ships space of running shaft, and this deficiency seems particularly outstanding at fisheries administration ship, volume private ship, naval vessels etc. to the higher ships of rate request.At present from heavy and light, boats and ships water lubrication seal arrangement that space hold is little is still rare does not also find in documents and materials.
Summary of the invention:
At the above-mentioned deficiency of existing in prior technology, technical problem to be solved by this invention is that a kind of spry and light type water lubrication seal arrangement peculiar to vessel will be provided, and it has in light weight, and the advantage that space hold is little is for the quick sailing of boats and ships provides technical guarantee.
In order to solve the problems of the technologies described above, the scheme of technical solution problem of the present invention is: spry and light type water lubrication seal arrangement peculiar to vessel, comprise around running shaft and be fixedly mounted on water lubrication sealing seat on the hull, around described running shaft and be fixedly mounted on end cover and water lubrication seal ring on the described water lubrication sealing seat, described end cover is provided with the static seal end face vertical with running shaft, described water lubrication seal ring places the interior volume that is surrounded by described water lubrication sealing seat and described end cover, and fixedly mount and encircle on the sheath that is wrapped in described running shaft outer surface, described static seal end face and described water lubrication seal ring constitute the end face seal pair, between described water lubrication seal ring and the described sheath seal ring lining are installed.
After adopting such scheme, because the water lubrication seal ring fixedly mounts and encircles on the sheath that is wrapped in described running shaft outer surface, the seal ring lining is installed between water lubrication seal ring and the sheath, has got rid of the axle sleeve of sheath outside, alleviated the weight of whole water lubrication seal arrangement; In addition, also got rid of axle sleeve has been fixedly mounted on device on the running shaft, effectively reduced the length of running shaft, both alleviated the weight of running shaft, the length of whole water lubrication seal arrangement and shared space thereof have also been reduced, this seems particularly important at fisheries administration ship, volume private ship, naval vessels etc. to the higher ships of rate request, for the quick sailing of boats and ships provides technical guarantee.
The outer surface of the ring support of water lubrication seal ring encloses spring with firm the fixing and encircling on sheath of water lubrication seal ring around the spring of enclosing is arranged, and does not have relative movement between water lubrication seal ring and the sheath, and sheath can not be worn; Sheath adopts the copper material of seawater corrosion resistance to make, and can protect running shaft to avoid seawater corrosion fully, thereby the technical solution used in the present invention is feasible.
The seal ring lining is installed between water lubrication seal ring and the sheath, is used for filling the inwall of ring support of water lubrication seal ring and the gap between the jacket outer surface, and this gap is that the internal diameter by the ring support of water lubrication seal ring forms greater than the sheath external diameter.The external diameter of having avoided the physical dimension of water lubrication seal ring to follow running shaft changes, and needs the loaded down with trivial details of frequent process water lubrication and seal ring mould, has also reduced cost of production.External diameter at running shaft changes under the little situation, can satisfy the needs of stern shaft seal fully.
The seal ring lining adopts macromolecular material to make.
The seal ring lining adopts metallic material to make.
