The amount of compression of the seal refers to the extent to which the seal can be compressed to achieve the best sealing effect when the seal is installed. The compression of the sealing ring is related to the material, shape, size and application scenario of the sealing ring.
The compression standard of sealing rings varies according to application scenarios and specifications. Here are a few common compression standards:
1.ANSI/NSF 51 standard: This standard applies to the sealing rings of food and beverage processing equipment. The required compression is between 10% and 20%.
2. O-ring: The compression of O-ring is usually between 10% and 30%. For low pressure applications, the amount of compression can be lower, while for high pressure applications, the amount of compression needs to be higher.
3. Rectangular sealing ring: The compression of rectangular sealing ring is usually between 10% and 20%.
4. Hydraulic seals: The compression of hydraulic seals is usually between 10% and 30%. For high-pressure applications, the amount of compression needs to be higher.
It should be noted that the above are only some common compression standards, and there may be differences in actual application. In addition, the amount of compression of the seal is also affected by other factors, such as the seal material, hardness, diameter and groove design. Therefore, it is recommended that when selecting and installing seals, the appropriate compression amount is determined according to the specific application and the manufacturer's recommendations.
