Product Description

These serial sealing arrangements are to be used as the tail shaft sealing of marine transport ships, river transport ships, working ships and military ships. They are applicable to the operating conditions that the full load draft of ships is less than *0 meters and the circular velocity of tail shafts is less than 5 m/s. This sealing arrangement consists of the front sealing arrangement and rear sealing arrangement and they are located at the front and rear ends of the tail tube bearing. The tail tube bearing is filled with lubricating oil from the gravity oil tank and the friction loss is reduced by oil film established by operation. The rear sealing arrangement not only prevents the lubricating oil to go out of the ship but also prevents the ship from water. The front sealing arrangement prevents the ship from the tail tube lubricating oil. The model consists of the model mark, quantity of sealing rings, symbol of sand prevention rings and specification and number. The specific description is shown below: Shaft diameter (internal diameter of the bushing) Specification (external diameter of the bushing) F—Sand prevention, D—Matter prevention ring W—Net protection, D—Matter prevention Quantity of sealing rings, 2, 3 or 4 Q—Front H—Rear Oil lubrication sealing arrangement
