How chemical mechanical seals leak due  to overheating damage

Once the overheating problem occurs in the chemical mechanical seal, the friction pair will be deformed, resulting in the wear of the seal, and thermal cracking may occur under more serious conditions.Under normal circumstances, when the thermal stress is relatively large, radial cracks will occur on the surface of the chemical mechanical seal ring,that is, thermal cracking. The phenomenon of thermal cracking generally occurs when the mechanical load or thermal load is large in a short period of time.Therefore, in order to effectively avoid the phenomenon of thermal cracking,when designing chemical mechanical seals, we must first grasp the physical properties of materials,and we must fully consider the thermal cracking that may occur in chemical mechanical seals; At the same time, when the operating temperature is too high, the lubricating performance of the medium is not high,and the material combination is not matched, the phenomenon of excessive friction heat will be caused. When the generated friction heat cannot be dissipated in time, thermal cracking will occur. Leakage may thus takes place.
