Whether vehicles or mechanical equipment, O-ring is an indispensable seal, and it is because of the seal, many industries can better development. For the first time to solve the sealing parts of friends, not deep understanding, so at the time of purchase, it is easy to fall into the procurement misunderstanding. Today we will talk about the relevant knowledge of the seal.
This kind of seal is actually a circular section of the seal ring, it is suitable for static gas and liquid medium seal, also suitable for reciprocating motion and rotary motion dynamic seal, we should choose according to the conditions of use.
O-ring in the selection should be as far as possible to choose a large section of the product, in the same clearance under the premise of the seal is squeezed into the clearance volume should be smaller than the allowed value.
The seal can be said to be an effective and economical sealing element, it has a bidirectional sealing effect, for different types of static sealing or dynamic sealing occasions, it is suitable. At the time of installation, whether radial or axial, it has initial compression, that is, it has initial sealing ability. In practical use, the sealing force generated by the system pressure and the initial sealing force combined will form a total sealing force, and the sealing force will increase because of the increase of the system pressure.
In the purchase of O-ring, to choose a large section, so that the sealing can play a better sealing role.
