Selection of mechanical seal structure type:

The selection of the mechanical seal structure type is an important step in the design process. When selecting the mechanical seal structure type, due to the diversity of the mechanical seal structure, it needs to be selected according to different purposes, specific use requirements and working conditions Appropriate structure type. In the preliminary selection, the following perspectives can be considered:

(1) Medium characteristics: concentration, viscosity, corrosiveness, presence or absence of solid particles and fiber impurities, whether it is easy to vaporize or crystallize, etc.;

(2) Working parameters: pressure and temperature of the sealed medium, shaft diameter and speed;

(3) The main engine (pump, kettle, process equipment, etc.) requirements for the allowable leakage volume and direction of the sealed medium, and the life and reliability requirements of the sealing device;

(4) The host's restriction on the structural size of the sealing device;

(5) Stability of operation and production process.
