AS-C287 Customized Single Cartridge Mechanical Seal

Background Knowledge：
Mechanical seal design conditions:
    The following items must be mastered before mechanical seal design:
     (1) The type of pump that uses the shaft mechanical seal and the position of the shaft seal;

     (2) Working parameters: pressure, temperature, peripheral speed (speed and shaft diameter) and their variation range;

     (3) Media properties: density, viscosity, saturated vapor pressure, particle size and concentration of solid particles, corrosiveness and crystallization, polymerization, and decomposition conditions;

     (4) Working nature: continuous operation, number of starts and stops, cycle, steering;

     (5) Working environment: ambient atmosphere, ambient temperature and pressure, including environmental conditions such as pollution, corrosion, movement, available coolant, lubricant, and shaft  mechanical seal position;

     (6) In other cases, the type and usage of the shaft mechanical seal used by the same type of pump.
