The function of the seal ring is mainly to seal. There are many mediums to seal, mainly oil. It plays the role of dust and oil isolation in the application. The performance of the seal ring directly affects the performance of other equipment. Good or bad, and the material that determines the performance of the seal ring is first of all. So how to choose the material of the seal ring? What factors are related to it, today Haisheng Rubber will give you a detailed introduction.
1. Mechanical movement speed. The adaptability of the material of the seal to the speed of the machine is different. Some common materials cannot adapt to high-speed mechanical operation. Therefore, when selecting the material of the seal, choose a high-end one so that high-speed operation can be used. .
2. Stress. The material of the seal ring is also very sensitive to the working pressure. Different materials can bear different pressures. If the medium is oil, it will bear a smaller pressure. If the pressure exceeds the material, The tolerance range of the seal ring will reduce the service life of the seal ring. You can choose it under the suggestion of the seal ring manufacturer.
3. Media compatibility. This has a very important role in the selection of the seal ring material. Some seal ring materials will directly contact the medium. If the compatibility between the two is not good, it will inevitably cause damage to the seal ring or contaminate the medium. In addition, the material of the seal ring cannot be corroded by introduction, nor can it react with the medium. This is also a special reminder of Haisheng Rubber.
When choosing the material of the seal, besides paying attention to the speed of movement, pressure, and compatibility of the medium, also pay attention to the temperature. The temperature also has a certain effect on the material of the seal ring. If the temperature is too high or too low, it will not work. If it is too high, it will reduce the stretch and hardness of the seal ring. If the temperature is too low, it will make the seal ring very brittle. Each seal material has its own temperature range, so please pay attention to this. Therefore, everyone must consider comprehensively when choosing the material of the seal ring. If it is difficult to choose oneself, you can consult the Haisheng rubber professionals.
