Seal failure reason analysis-- overheating
Because the sealing surface will produce heat use temperature should be lower than design specification rubber ring.The use of fluorine rubber and teflon temperature is 216 ℃, the use of nitrile butadiene rubber temperature is 162 ℃, although they are able to withstand higher temperatures, but because of the sealing surface heat is higher, so the rubber ring is in danger of continue to sulfide, eventually lose elasticity and leakage.(cold area consider cold short)
Also caused by thermal medium crystal surface, such as carbon, caused by sticking and sealing surface by condensation sliding parts.And some of the polymer in overheating and coking, some fluid lost even lubrication and flash fire due to overheating.
Overheating except can change the condition of the medium, but also increases its corrosion rate.Cause deformation of the metal parts, alloy surface cracking, and some coating cracks, the design should choose the balance type mechanical seal, in order to reduce the pressure to prevent overheating.
