ABB 3AFV3478184 Mechanical Oil Seal for AZIPOD Podded Propulsion
I. Product Overview
The ABB 3AFV3478184 is a mechanical oil seal supplied by ABB for Azipod podded propulsion, with material number 3AFV3478184. This mechanical oil seal is installed at the Azipod propulsor shaft line, used to se al the lubricating oil chamber, preventing oil leakage and seawater ingress, serving as the key spare part of the propulsor sealing system.
The Azipod sealing system comprises a series of elastomer seals mounted on the propeller shaft, with sealing oil contained between adjacent seal rings, ensuring high-quality lubrication and cooling of the sealing system. The Azipod propeller bearing side typically consists of multiple seal rings forming multi-stage seal chambers: the outermost seal rings form the first chamber against the seawater, filled with grease as a dirt barrier; the second chamber is filled with pressurized air, collecting leakage from the bearing housing or seawater side and draining to the drainage system at specified intervals. The mechanical oil seal is the sealing element in this shaft line seal system, maintaining isolation between the lubricating oil chamber and the outside.
The 3AFV3478184 mechanical oil seal adopts a mechanical seal structure, suitable for dynamic sealing of the Azipod propulsor shaft line under rotation. This oil seal achieves reliable lubricating oil sealing through mating seal faces and secondary seals. The 3AFV3478184 mechanical oil seal carries an official ABB Marine & Ports material number (3AFV code system), suitable for vessel dry-docking, periodic seal inspection and replacement of corresponding Azipod podded propulsion. For specific shaft diameter, construction, materials and other technical parameters, please contact via email for confirmation.
