Understanding rubber seals Selection
1, confirm the installation of rubber seals is consistent with the requirements of the model;
2, rubber seals before installation to be careful with the assembly drawing control, the number of parts are complete;
3, coil spring and rubber seal with the transmission of the mechanical seal, which spring has left and right hand points, shall always choose rotary shaft.
When using the sealing material can be formulated as a liquid or a paste, applied to the contact surface between the two members, under certain conditions was cured or non-drying putty acts as a seal; it can also be processed into various shapes or solid hollow ring mounted on the contact surface between the two parts of the sealed role. Former said sealing material is only used for two component contact surface is no relative motion of the static sealing parts; the latter, said seal both for static sealing parts, but also for members of the two contact surfaces in relative motion with dynamic sealing parts.
Performance rubber seal materials and characteristics:
(1) a solid rubber ring content (> 94%), almost no shrinkage after curing.
(2) rubber seal paste is good, with the most common building materials (such as concrete, steel, aluminum, wood, glass, etc.) bonding.
(3) rubber seals high elongation, fatigue resistance, resistance to stress and aging resistance outstanding.
(4) rubber seals high water resistance, anti-microbial corrosion.
