Large Size Seals: Precautions for Storage of Seals

The fluid sealing device in the large-size seal is widely used in the engineering fields of machinery, petroleum, chemical, water conservancy, electric power, light industry, pharmaceutical, urban construction and nuclear industry. With the rapid development of modern chemical, petroleum, atomic energy, aerospace and deep-sea technology, more and more requirements are put forward for the sealing of equipment. However, the failure of large-scale sealing will cause a large amount of waste of energy and raw materials, and the heavy will lead to equipment scrapping, shutdown, and even cause casualties and serious environmental pollution. Therefore, more attention should be paid to the correct use of seals, especially in storage.

However, the failure of large-scale sealing will cause a large amount of waste of energy and raw materials, and the heavy will lead to equipment scrapping, shutdown, and even cause casualties and serious environmental pollution. Therefore, more attention should be paid to the correct use of seals, especially in storage.

When storingLarge size sealType of accessories, please note the following:

1. Do not open the seal package when it is not necessary, otherwise dust will stick to the seal or scratch the seal;

2. Store in a cool place, avoid direct sunlight, high temperature and high humidity in the warehouse, and keep it in standard packaging. Ultraviolet rays and water vapor will accelerate the deterioration and size change of rubber and plastic;

3. When storing unpackaged products, be careful not to stick or pack impurities, store them according to the original state, and seal nylon to prevent water from causing dimensional changes;

4, do not put the seal near the heat source, such as boilers, furnaces, etc., heat will accelerate the aging of the seal;

5. Do notLarge size sealType accessories are placed close to the motor and where ozone is generated;

6. Do not use a needle, wire, rope hanging seals, otherwise, will make the seal deformation, damage the lip;

7. SometimesLarge size sealThe color change or white powder appears on the surface, which will not affect the performance of the seal;

8. In the use of long-term storage, should confirm whether there is rust.
