China O Ring Mechanical Seals Manufacturers WM103B

China O ring mechanical seals WM103B by mechanical deformation that creates a barrier to a fluid’s potential leak path between two closely mated surfaces. O ring mechanical seals are typically installed in a groove that’s machined or molded in one of the surfaces to be sealed. Their rubber-like properties let the devices compensate for dimensional variations in the mating parts.

Product Description

As China's famous O ring mechanical seals manufacturers, Wendong carries many different types of mechanical seals and O ring mechanical seals -most available for immediate shipping.


Successful o ring mechanical seals joint design requires a rigid mechanical mounting that applies a predictable deformation to the O-ring. This introduces calculated mechanical stress at the O-ring contacting surfaces. As long as the pressure of the fluid being contained does not exceed the contact stress of the O-ring, leaking cannot occur. The pressure of the contained fluid transfers through the essentially incompressible o ring mechanical seals material and the contact stress rises with increasing pressure. For this reason, an O ring mechanical seals WM103B can easily seal high pressure as long as it does not fail mechanically. 


What is the difference between static and dynamic o ring mechanical seals?


Static and dynamic o ring mechanical seals design differs in a few key ways. A static O-ring is any o-ring designed to contact with two or more surfaces that do not move relative to one another, whereas a dynamic O-ring is one that helps form a seal between moving parts.


On the whole, static o ring mechanical seals are created from less robust and hard-wearing materials than their dynamic equivalents. It’s also important that the components being joined together in a dynamic environment are carefully designed and finished, such that they will not abrade, shear, and eventually destroy the O-ring positioned between them. This is less of a concern for o ring mechanical seals used in static applications, as the only stress force they’ll be under is usually compression (to which they tend to be fairly resilient).


While all o ring mechanical seals require some degree of lubrication in order to perform to optimal levels, dynamic o-rings require heavier and more frequent lubrication (as well as more regular checking, maintenance, and replacement) than static versions. Different types of dynamic movements - for example, rotary, reciprocating, and oscillating - demand that o ring mechanical seals be manufactured with different material qualities to perform to the optimal level.
