Mechanical seal according to the different working conditions and media properties can be divided into high temperature, low temperature mechanical seals, mechanical seal manufacturers Texas, high pressure, corrosion-resistant mechanical seals, mechanical seal manufacturers, mechanical seal resistant to particulate media and adapt easily vaporized light hydrocarbon medium, mechanical seals, mechanical seal should choose a different structure types and materials depending on the use. Selection of the main parameters are: the seal chamber pressure (MPA), fluid temperature (℃), working speed (M / S), characteristics of the fluid and the installation of an effective seal space and single mechanical seal as compared to double mechanical seal one more friction. Two friction respectively by the two stationary ring can also be composed of two ring ring two share a stationary ring or two rings share a stationary ring components. Double mechanical seal a variety of classification methods. Check
