How much do you know about the installation and use of O-ring seals?
O-ring seal ring is called O-ring for short. It is a kind of rubber ring with circular section shape. O-ring is the most widely used seal in hydraulic and pneumatic systems. O-ring has good sealing performance, which can be used in both static seal and dynamic seal;
The installation quality of O-ring has an important impact on its sealing performance and service life. Leakage problems are often caused by poor installation.
During installation, O-rings are not allowed to be scratched, installed incorrectly, or twisted. Before assembly, the sealing groove and sealing mating surface must be strictly cleaned; At the same time, apply grease to the surface to be passed during O-ring assembly.
In order to prevent the O-ring from being cut or scratched by sharp edges such as sharp corners and threads during installation, a lead-in angle of 15 º ~ 30 º shall be reserved at the installed shaft end and hole end. When the O-ring needs to pass through the external thread, a special thin-wall metal guide sleeve shall be used to cover the external thread; If the O-ring needs to pass through the orifice, the orifice shall be inverted into the corresponding bevel shape to prevent the O-ring from being scratched. The bevel angle of the groove is generally a = 120 º ~ 140 º
