The sealing ring mainly plays the role of dust and oil separation in the application. There are also many media it seals, mainly oil. Therefore, the performance of the sealing ring directly affects the performance of other equipment, and the decision The first performance of the sealing ring is its material. So how to choose the material of the sealing ring? What factors are it related to? Today, the silicone rubber manufacturer of the sealing ring will give you a detailed introduction.

1. Mechanical speed. The material of the seal has different adaptability to the speed of mechanical movement. Some ordinary materials cannot adapt to high-speed mechanical operation. Therefore, when selecting the material of the sealing ring, high-end ones should be selected, so that high-speed operation can be used. .

2. Pressure. The material of the sealing ring is also very sensitive to the working pressure. Different materials have different pressures that they can bear. If the medium is oil, the pressure it bears is smaller. If the pressure it bears exceeds the material The bearing range of the sealing ring will reduce the service life of the sealing ring. This can be selected under the recommendation of the sealing ring manufacturer.

3. Medium compatibility. This plays a very important role in the selection of sealing ring materials. Some sealing ring materials will be in direct contact with the medium. If the compatibility between the two is not good, it is bound to cause damage to the sealing ring or contaminate the medium. In addition, the material of the sealing ring cannot be corroded by the medium, nor can it react chemically with the medium, which is also a point that the sealing ring manufacturer specially reminds everyone.

4. When choosing the material of the sealing ring, in addition to paying attention to the speed of movement, pressure, and compatibility of the medium, it is also necessary to pay attention to the temperature. The temperature also has a certain influence on the material of the sealing ring. If the temperature is too high or too low, it will not work. If the temperature is too high, the tensile strength and hardness of the sealing ring will be reduced. If the temperature is too low, the sealing ring will become very weak. crisp. Each sealing ring material has its own temperature range, which should also be noted.
