Oil seals are precision components, which affect the performance of use and improperly reserve. Pay attention to oil seal when transportation and storage:
1. Do not open the original packaging, pay attention to whether the packaging is damaged. Try to keep the oil in the original packaging before assembly;
2. Avoid direct sunlight, do not place near high temperature heat sources, because this will promote the aging of rubber;
3. The oil seal must not be dispersed at will. Pay attention to dust prevention and prevention, and ensure that the oil seal is closed or covered;
4. When transporting and using oil seal, in order to prevent the deformation of oil seal and the spring falling off, please do not give too much impact;
5, the oil seal can not be tied with a fine rope, and do not hang on the nail or metal line, which will damage the sealing lip;
6. Do not seal the oil in a humid place, which will rust the metal parts;
7. Do not put the sealing parts near TV and producing ozone;
8. Please do not rub the ends of the lips with your nails or hard objects to prevent damage to the sealing lips;
High-efficiency china high temperature oil seal is mainly composed of sealing body, reinforcing frame and self-tightening coil spring. The sealing body is divided into bottom, waist, vane and sealing lip according to different parts.
The metal skeleton is like the reinforcement in the concrete component, which plays an enhanced role and enables the oil seal to maintain the shape and tension. Generally, the inner diameter in the skeleton in a free state is smaller than the axis diameter, which has a certain “over -profile”.
Therefore, when the oil is encapsulated into the oil seal and the shaft, the pressure of the oil seal blade and the contraction force of the self -tight screw spring can generate a certain radial tight force on the shaft. After a period of operation, the pressure will quickly decrease or even disappear. Therefore, the spring can compensate the oil at any time.
While the outer edge of the oil seal is fixed in the cavity hole, it will prevent the fluid from leaking and invasion between the contact surface of the outer surface of the oil from the outer surface of the oil and the inner surface of the cavity. In addition, the metal skeleton is to maintain the effect of maintaining a cooperative force when the oil seal is fixed in the cavity.
The sealing lip is a flexible elastic body, which is designed to maintain a stable sealing effect under the influence of the vibration of mechanical vibration and the pressure changes of the sealing fluid, and play a role in maintaining the stable contact state of the lip and axis surface. Spring can increase the tightness of the sealing lips to the axis to maintain this pressure. The end of the lips is made into a oblique shape, and the surface of the part is pressed at the end of the end to seal the fluid. The dust -proof lips are the auxiliary lips that are not connected to the spring, which plays a role in preventing dust invasion.
