Vessel Oil lubrication stern shaft sealing apparatus
This series can be used as sealing means ocean transport vessels , work boats , military vessels and inland waterway vessels auxiliary oil-lubricated stern shaft seal . Applicable reference axis for the ship loaded draft < 20 m , stern bush circumferential speed <7 m / s working conditions.
1.The device is divided into two portions before and after sealing means sealing means are mounted in the front and rear ends of the stern tube , filled with lubricating oil from the gravity of the cabinet in the tail pipe bearing , relying on the establishment of the film during the operation to reduce wear and friction loss of the bearing . After sealing means both to prevent the lubricating oil from leaking to the tail pipe overboard , while preventing seawater immersion , before sealing means to prevent the lubricating oil from leaking to the tail pipe overboard.2.After sealing device :
After sealing device has three main parts: the fixed to the stern tube and the metal shell rotates together with the propeller shaft liner and rubber seals. By the housing body seal seat , closures and other components, these components are bolted together and pressed seal. Lip seals in contact with the liner . Due to the water pressure , oil pressure and the elastic force of the rubber itself and the spring force of the tightening , so that between the liner and the lip to maintain a certain radial force , thereby maintaining the seal . Seal mark from the end of the date the order of # 1 , # 2 , # 3 and 3s #. # 1 and # 2 for the ring seal seawater ; tailpipe lubricants by 3 and 3s # # ring seal . Sediment more of navigation area , in order to protect the normal operation of the sealing device to extend the life of the outside also added a circle and Sediment Control.
Before sealing means :
Structure of the front and rear sealing means sealing means is substantially the same , except that only two seals . Seals, spring and the rear seal the same. Bush with locking bolts fastening the upper and lower clamp ring on the propeller shaft . Token ring counting from the tail pipe side order of # 4 , # 5 . # 4 ring seal tail pipe oil, and ring seal 5 # 4 # 5 # and seal oil chamber . Lubricant between # 4 and # 5 is equipped with a circulator seal the sealing chamber before sealing the fuel tank between the rotary axis and rely on automatic recirculating lubrication.
