Common mechanical seal cooling and flushing methods Mechanical seal cooling and flushing methods are indispensable operating points during product use, but many users know this operation, but do not understand the specific operating points, so the following is a detailed introduction to it. Due to the friction of the end face, a large amount of friction heat will be generated, which will increase the temperature of the friction ring. At the same time, if the temperature of the sealing medium itself is relatively high, the end face of the friction pair will always operate at a very high temperature. In this case, if no flushing and cooling measures are taken, it will cause: (1) The liquid film between the end surfaces evaporates and dry friction occurs; (2) The auxiliary sealing ring made of rubber and plastic materials will age, crack and even fail; (3) Accelerate the corrosion effect of the sealing medium on the sealing parts; (4) Dynamic and static ring deformation; (5) Increased en...

Various criteria for the life of mechanical seals Because the life of mechanical seals is directly related to the performance and efficiency of equipment, we need to introduce and understand the various criteria for the life of their accessories. It is well known that mechanical seals are one of the basic mechanical components with fine, dense and complex structure. They are the key components of various pumps, reaction synthesis kettles, turbo compressors, submersible motors and other equipment. Its sealing performance and service life depend on many factors, such as type selection, machine accuracy, correct installation and use, etc. According to the different working conditions and the nature of the medium, there are high temperature and low temperature resistant seals, high pressure resistant, corrosion resistant seals, particle resistant medium seals and seals suitable for light hydrocarbon media that are easy to vaporize, etc., according to different uses Choose seals of differe...
