Precautions for the storage of seal oil seal:

1. Do not open when not needed;

2. It shall not be placed in the place with long-term sunlight and soil and sand pollution; 3. It shall not be placed in the humid place and near the heat source; 4. When unpacking, it is not allowed to hang with wire or string; 5. It is not allowed to deform the oil seal;

Leakage related factors

The oil seal can prevent leakage under dynamic and static conditions by controlling the interference between the lip and the mating surface. At the same time, the following conditions must be met:

1. In the free state, the inner diameter of the oil seal lip is smaller than the shaft diameter, and has a certain amount of interference.

2. After installation, the interference pressure of the oil seal blade and the contraction force of the self tightening spring produce radial pressure on the rotating shaft.

3. When the machine is working, under the action of the radial pressure of the oil seal lip, a 0.25-0.5mm sealing contact ring is formed. Under the action of the internal lubricating oil pressure, part of the oil penetrates between the oil seal blade and the shaft, forming a very thin oil film. Under the action of the surface tension of the oil, a "crescent surface" is formed between the rotating shaft and the oil seal blade to prevent the oil from overflowing and achieve the sealing effect
