However, as a fluid name only describes frequently used fluid media names, for unusually used fluids and from other factors such as viscosity, saturated vapor pressure, vaporization temperature, flow, specific gravity, corrosion performance, or the like, or may not provide initial Conditions estimated value On the other hand, due to the fact that the fluid properties of the rotary joint is not clear, it is sometimes causing abnormal wear of corrosion or causing friction.
Thus, efforts should be made to make instructions clearly, thus avoiding failures caused by errors in selection or applicable. For rotary joint bellows or bellows, spring combined elastic element structures, the failure of the bellows can also result in leakage and reliability. The rotary joint bellows is completely or partially losing its ability to fail. This failure form characterizes so-called intensity reliability of the bellows when it is characterized by the damage of OEM Brass Fitting Factory the bellows.
If the bellows are not completely lost, it is only manifested as the work parameters of the bellows deviates to the allowable range, it is called partial failure. Therefore, partial failure characterizes its parameter reliability. When fully failed, the application is completely lost due to the rotary joint bellows; when the component is faded, the capacity of the work can retain the work, just a low quality level.
The rotary joint can be used in a variety of different parameters, except for leak loss, life and power consumption, the safety and work reliability of the seal have great significance. The rotary joint of the mechanical sealing structure suddenly malfunctions compared to ordinary filler seals.
For example, due to the separation of the sealing surface, the crack of the sealing ring, the thermal stress crack on the friction surface, and the high temperature and temperature difference that are not allowed.
