Problems solved by technology

The disadvantage of this kind of sealing device is that the mass of the shaft sleeve and its additional equipment is relatively large, and the length of the rotating shaft and the space of the ship need to be additionally increased. The disadvantage is that fishery ships, private boats, ships, etc. have high speed requirements. It is particularly prominent on the ship
At present, there are few water-lubricated sealing devices for ships with light weight and small space occupation, and they have not been found in the literature.

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: [0001] The invention relates to marine equipment, in particular to the improvement of a marine water lubricating sealing device. Background technique: [0002] The water-lubricated sealing device is one of the commonly used sealing devices in ships. It is mainly used to prevent seawater from entering the ship from the connection between the stern shaft and the hull. The quality of its sealing performance directly affects the safe operation of the ship and is an important component of the ship. part. The current marine water lubrication sealing device includes a water lubrication sealing seat that surrounds the rotating shaft and is fixedly installed on the hull, a sealing end cover that surrounds the rotating shaft and is fixedly installed on the water lubricating sealing seat, and a water lubrication sealing seat and a sealing end. The space enclosed by the cover is fixedly installed and surrounds the water-lubricated sealing ring on the shaft sleeve. The ...
