What should we pay attention to when selecting the material of the sealing ring?
The role of the sealing ring is mainly seal, it also has a lot of sealing medium, mainly oil is given priority to, it plays in the application of the effect of dust and oil separation, seal performance is good or bad a direct impact on the stand or fall of other equipment performance, and decided to seal performance of the first is the material of it. So how to choose the material of the seal ring? It is concerned with which factors, today sealing ring manufacturers will give you a specific introduction.
1. Mechanical movement speed. Seal material the ability to adapt to mechanical movement speed is different, some of the common material, can't adapt to the high-speed mechanical operation, therefore, sealing ring material when the choice, should choose some high-end, so you can use high speed running.
Pressure. Seal material for work pressure is also very sensitive, material is qualitative different, they are able to withstand the pressure is different, if the medium is oil, it is the pressure is smaller, if pressure more than the material, then it makes the service life of the sealing ring is reduced, the everyone can choose under the seal manufacturer's advice.
3. Media compatibility. For the sealing ring has a very important role in the choice of materials, some will seal material and medium directly in contact, if both compatibility is not good, is bound to cause pollution of the sealing ring is damaged or to medium. In addition, the material of the sealing ring cannot be introduced to corrode, nor can it react with the media. This is also a special reminder from the manufacturer of the sealing ring.
When selecting the sealing ring material, attention should be paid to not only the motion speed, pressure and media compatibility, but also the temperature. Temperature also have certain influence to the material of sealing ring, the temperature is too high or too low is not enough, too, can make the tensile strength and hardness of the sealing ring is reduced, the temperature is too low, can make sealing ring is very fragile. Each seal material has its own temperature range, which should also be noted. Therefore, when you choose the sealing ring material, you must take comprehensive consideration. If it is difficult for you to choose, you can consult the sealing ring manufacturer.
