Abstract
The utility model relates to a pod propeller sealing device which comprises a sealing shell, a lip-shaped sealing ring component, a mounting ring, a corrugated pipe component, a surface sealing piece, a surface sealing base and a surface sealing erection loop, wherein the surface sealing base and the surface sealing erection loop are fixedly connected with a shaft sleeve; the surface sealing piece is arranged in the surface sealing base; one end of a corrugated pipe leans against the surface sealing piece, and the other end of the corrugated pipe is arranged on the erection loop; and the installed corrugated pipe is connected with the sealing shell by the lip-shaped sealing ring component. The utility model provides the pod propeller sealing device capable of improving the sealing performance.
Description
Technical field
The utility model belongs to marine propeller, especially a kind of propelling unit sealing arrangement.
Background technology
Pod propulsion electric propulsion device: diesel powerplant generating; Drive electrical motor---screw propeller unit in the outside gondola of hull indirectly through cable connection; It has broken through the propeller design fixed pattern that diesel engine adds open transmission shafting, places the screw propeller drive motor in the rotating gondola of ability 360 degree to be suspended under the ship, integrates propelling unit and steering gear; Saved common propeller shaft system and the rudder of using; Thereby greatly having increased the alerting ability of ship design, construction and use, made the preceence of electric propulsion obtain embodying more fully, is the novel propelling unit that receives world's ship building industry extensive concern at present.Because motor is contained under water, so the sealing of PODDED PROPULSOR is most important.
Summary of the invention
For the relatively poor deficiency of the sealing property that overcomes existing propelling unit hermetically-sealed construction, the utility model provides a kind of PODDED PROPULSOR sealing arrangement of lift-off seal performance.
The utility model solves the technical scheme that its technical matters adopted:
A kind of PODDED PROPULSOR sealing arrangement; Comprise seal casinghousing, lip packing ring assemblies, installation ring, bellows component, face seal, face sealing seat and face sealing installation ring; The face sealing seat is captiveed joint with axle sleeve with the face sealing installation ring, and said face seal is positioned at the face sealing seat, and an end of said bellows withstands on the said face seal; The other end of said bellows is installed on the installation ring, and said installation back is connected with seal casinghousing through the lip packing ring assemblies.
The technical conceive of the utility model is: the sealing device is the combination sealing form, is combined by the face sealing of one water lubricating and the lip packing of twice grease lubrication, and wherein the face sealing of water lubricating is a primary seal, and twice grease lubrication is sealed into auxiliary seal.Adopt the combination of twice lip packing, improve the leak free reliability, prevent to be equipped with in the gondola of motor not having the seawater entering more reliably with the water lubricating face sealing.Simultaneously, according to water lubricating leak free characteristics, in the chamber between water lubricating sealing and the grease lubrication sealing, have two paths, the one road leads to pressurized air to this chamber in hull, and another road links to each other this chamber with the PODDED PROPULSOR sewage collecting cabinet of hull interior.Using sealing after a period of time,, the seawater of water lubricating seal leakage is being forced in the sewage collecting cabinet to the logical pressurized air of this chamber.So just can monitor water lubricating leak free leak volume, thus the monitoring of realization sealing effectiveness.
The beneficial effect of the utility model mainly shows: seal more reliably and can measure sealing effectiveness.
Description of drawings
Fig. 1 is the scheme drawing of PODDED PROPULSOR sealing arrangement.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, a kind of PODDED PROPULSOR sealing arrangement comprises seal casinghousing 1, lip packing ring assemblies 2, installation ring 3, bellows component 4, face sealing 5, face sealing seat 6, face sealing installation ring 7.Wherein: face sealing seat 6 is connected with axle sleeve through screw with face sealing installation ring 7, so face sealing seat 6 and face sealing installation ring 7 rotate along with the rotation of axle, and miscellaneous part is static.The effect of bellows 4: face sealing 5 in use can be by wearing and tearing constantly with face sealing seat 6; And in this process; Bellows component 4 is in the resilient force of itself, and compressive plane sealing constantly 5 makes the wearing and tearing of face sealing 5 and face sealing seat 6 constantly be compensated.When mounted, in lip packing ring assemblies 2, be full of grease.
