Selection, installation and storage of O-rings
Product selection:
There are many types of sealing O-rings.
According to the sealing purpose, they can be divided into hole seals, shaft seals and rotary
shaft seals. According to the type of load, they can be divided into dynamic seals and There are two types of static seals. According to the form of installation, they can be divided into two types: radial installation and axial installation.
2. Working medium and conditions
When selecting a model, it needs to be considered according to the environment and purpose of use, such as the temperature of the seal. Continuous working time. For conditions such as pressure and working cycle, select materials that are compatible with the working medium. If there is rotation during work, you need to consider the friction and temperature rise caused by the rotation.
3.Installation method:
The installation part and the place through the sealing O-ring should be smooth, without burrs, sharp corners and grooves. Generally, the cross-section of the shaft should be 10 mils, and the inner hole cut should be 20 mils
Add grease to the surface of the product and the parts in contact with it. If the installation place is a shaft, the sealing O-ring can be soaked in hot water for a while before installation to let it expand and soften, so that it is easier to install, and it will be restored to the original after cooling down. Size and dimensions.Do not bend violently during installation, especially not foldable, so as not to affect the sealing effect.
4. Storage method:
Sealed O-rings cannot be compressed or stretched during storage. They should be stored in a ventilated and dry environment and avoid direct sunlight.
