Overview
Mechanical seal gasket PTFE gasket $r $n PTFE gasket, also known as PTFE gasket or Teflon gasket in foreign countries, is a flat gasket, V-shaped gasket, piston ring, ball valve gasket, etc. made by mechanical turning or cutting of polytetrafluoroethylene rods, pipes, and plates. In fluid machinery such as pumps, compressors, mixing kettles, centrifuges, etc., the most demanding components under operating conditions are PTFE gaskets.

Strictness
In fluid machinery such as pumps, compressors, mixing kettles, centrifuges, etc., the most demanding components under operating conditions are PTFE gaskets.
(1) Elephantthrust bearingAccept axial force in that way;
(2) Export the generated heat like a radiator;
(3) Under high temperature and pressure conditions that are prone to corrosion, static sealing is now very difficult, and dynamic sealing on a sealing surface of a few millimeters becomes even more challenging during high-speed rotation.
(1) Without an auxiliary system, we can only improve the sealing layout and improve raw materials. (High cost, unable to fundamentally solve the problem)
(2) In practical assignments, there are almost no PTFE gaskets that do not require any auxiliary equipment. Corresponding auxiliary equipment must be selected for series PTFE gaskets and high-temperature PTFE gaskets used in high-pressure applications.
(3) The harsh working conditions have been transformed into sealed and acceptable working conditions through the assistance system. (The role of PTFE gaskets has greatly improved, with a wider range of applications, reduced demand for sealing materials, and reduced cost of PTFE gaskets)[2]
Excessive heat from end face conflicts can cause the following damages:
(1) Liquid film vaporization wear exacerbates seal failure;
(2) End face thermal deformation increases leakage and wear;
(3) Intensify corrosion;
(4) Assist in the aging and degradation of the sealing ring before it fails;
(5) Leakage occurs due to carbonization or melting of graphite impregnated material.
So the end face temperature rise is the enemy of PTFE gaskets.
(1) Reduce temperature rise and adhere to outstanding and smooth end faces (Make all parts of the PTFE gasket outstanding and operate normally)
(2) Maintain a sealed chamber pressure higher than the full vapor pressure (in easily vaporized media) to prevent vaporization.
(3) Insulate and supply heat in low-temperature pumps.
(4) Regarding the crystallization of solid particles and the sealing of strongly corrosive media, it can maintain the seal without damage.
5. Under better working conditions, choosing an auxiliary system will improve sealing stability and service life. (Some sealing operations have low temperature, pressure, and speed. They can be operated without the need for auxiliary systems.)
6. The auxiliary system is a component of the PTFE gasket
