In seals, what is the problem when fluororubber O-rings are extruded?

Seal rings often manifest themselves as leakage, damage, high power consumption, overheating, smoke, vibration and other fault causes. DLSEALS tells you, taking the pump sealing ring as an example, it explains in detail the various failure phenomena, causes and consequences of the sealing ring.

1. Seal ring failure and fluorine rubber O-ring extrusion failure diagram:

2. The reason why the fluorine rubber O-ring is extruded due to sealing ring failure: When part of the O-ring is forced to pass through a small gap, it will be extruded. This can occur if the sealing element is assembled or assembled with too much strength or if the operating pressure and temperature are too high. When the shaft seal is adjusted on the spot, if the specifications go out of the limit, a large gap will be formed between the sealing elements, and the O-ring will also be extruded.

3. Seal ring failure Symptoms and countermeasures of fluorine rubber O-ring extrusion: Symptoms of fluorine rubber O-ring extrusion: O-type sealing ring cuts or tears the skin, and O-type sealing ring curls. Countermeasures for fluorine rubber O-ring extrusion: Check assembly methods and operating conditions. Ensure that sealing components are adjusted to original design requirements or re-planned by the manufacturer.
