Function Introduction of Mechanical Seal System-Mechanical Seal-

The function of mechanical seal system:

(1) Flushing function

Flushing is a very basic function of the mechanical seal system, and it is also a very common working method of the mechanical seal system. It directly injects liquid into the high-pressure side part of the single-end seal or double-end seal. Generally, mechanical seals should be flushed, especially those used for light hydrocarbon pumps. When flushing to achieve the goal of isolating the medium, cooling and improving lubrication. The purpose of isolating the medium can be achieved by externally circulating the liquid that is compatible with the medium in the sealed cavity.

(2) The function of regulating and controlling the working temperature of the seal

The mechanical seal system has the function of controlling and controlling the temperature of the working environment of the mechanical seal itself. The regulation and control of temperature includes cooling and keeping warm. The medium with high saturated vapor pressure absorbs the stirring heat of the mechanical seal and the friction heat of the end face in the sealing cavity, causing the temperature to rise; if it is insufficient to cool down, it is very likely to cause the medium to vaporize on the end face, which will deteriorate the lubrication of the end face and cause the seal invalid. For the medium that is easy to crystallize and solidify, heat preservation measures should be taken to prevent the medium from crystallizing and solidifying.
