Abstract
The utility model relates to a water-lubricating sealing ring which comprises a supporting face (1), a sealing lip (3) and compensating grooves (4). The supporting face (1) is arranged on the outer edge of the sealing ring; and lubricating passages (2) are evenly distributed on the supporting face (1), and the lubricating passages (2) are rectangular notches. In the utility model, proper amount of water-lubricating passages (2) are arranged on the outer edge of the supporting face (1) of the sealing ring without destructing a sealing ring body and a sealing end cover or influencing the intensity of the sealing ring, so that lubricating water directly enters the water-lubricating passages (2) through a water inlet pipe to circularly wash the sealing lip (3) of the water-lubricating sealing ring and fulfill the cooling function.
Description
Technical field
The utility model relates to a kind of water lubrication seal ring, is specifically to be used for screw shaft of ship water lubrication seal arrangement.
Background technique
At present, domestic screw shaft of ship water lubrication seal arrangement commonly used is a circulation water channel in adopting, and the water of discharging from the end cover many places cools off the seal ring lip, lubricate; Because any water quality all can have impurity and incrustation scale, all to clear up after use a period of time water channel, just can avoid the water channel blocking.Impurity does not too much not only reach sealing effect, and can cause frictional heat, influences the working life of seal ring simultaneously.
Summary of the invention
At above defective, the utility model provides a kind of water lubrication seal ring, do not destroying seal ring body and end cover, simultaneously do not influence under the situation of seal ring intensity yet, on the outer of water lubrication seal ring supporting surface, open up the proper amount of water lubrication channel, make lubricated water directly enter the water lubrication passage lubrication and seal circle lip is carried out circulation flushing, play cooling action by intake pipe.
In order to reach above purpose, the utility model has adopted following technological scheme: a kind of water lubrication seal ring, comprise supporting surface, seal lip, compensating tank, and described supporting surface is positioned at the seal ring outer, is evenly distributed with lubrication channel on the described supporting surface.
Lubrication channel described in the utility model is a rectangular notch.
After adopting above technological scheme, the utlity model has following beneficial effect: increase the water lubrication seal arrangement in boats and ships working times, prolong water lubrication seal ring service time, reduce seal ring and change number of times, thereby improve ship efficient.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model A-A sectional view.
Fig. 3 is the utility model user mode figure.
Embodiment
According to Fig. 1, shown in Figure 2, a kind of water lubrication seal ring of the utility model comprises supporting surface 1, seal lip 3, compensating tank 4, and described supporting surface 1 is positioned at the seal ring outer, is evenly distributed with lubrication channel 2 on the described supporting surface 1.
According to shown in Figure 3, a kind of water lubrication seal ring of the utility model, it is looped around on the screw shaft of ship, with end sealing cover interference fit, parallel friction.
Claims (2)
1. a water lubrication seal ring comprises supporting surface (1), seal lip (3), compensating tank (4), and described supporting surface (1) is positioned at the seal ring outer, it is characterized in that being evenly distributed with on the described supporting surface (1) lubrication channel (2).
2. a kind of water lubrication seal ring according to claim 1 is characterized in that lubrication channel (2) is a rectangular notch.
