PTFE combination of mechanical seal! Shanghai excellent sealing most worthy of trust! (YOUQI) is a precision mechanical seals, mechanical basic element of a more complex structure, according to the mechanical seal according to the different working conditions and the nature of the medium, there are high temperature, low temperature mechanical seals, high pressure, corrosion-resistant mechanical seal, resistance particles Media mechanical seals and mechanical seals adapt easily vaporized light hydrocarbons and other media should be selected mechanical seal types and materials of different structures depending on the use. Seal chamber pressure (MPA), fluid temperature (℃), working speed (M / S), fluid characteristics and available space to install seals and other mechanical seals selected working conditions. If, pursuant to seal chamber pressure, determine the sealing structure using balanced or unbalanced type, single face or double face like; according to the working speed, determine the use of rotary or static, fluid dynamic pressure type non-contact type; the installation seal available space, determine the use of multiple springs or single spring or wave spring, built-in or externally mounted; depending on the temperature and fluid properties to determine friction and auxiliary sealing materials, as well as the correct choice of lubrication, wash, heat, cooling and other mechanical seal circulation protection system and so on.
