(1) Flushing function

Flushing is the *basic function of the mechanical seal system, and it is also the *common working method of the mechanical seal system. It is directed to the high pressure side of the single end face seal or the double end face seal to inject liquid directly. Generally, mechanical seals should be flushed, especially for light hydrocarbon pumps. Flushing can achieve the purpose of isolating the medium, cooling and improving lubrication. The purpose of isolating the medium can be achieved by passing a liquid compatible with the medium into the sealed cavity for external circulation flushing.

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

The mechanical seal system has the function of adjusting and controlling the temperature of the working environment of the mechanical seal itself. Temperature adjustment and control include cooling and heat preservation. The medium with high saturated vapor pressure absorbs the stirring heat of the mechanical seal and the frictional heat of the end face in the sealed cavity, causing the temperature to rise; if the cooling is not carried out in time, it is likely to cause the medium to vaporize on the end face, worsening the lubrication of the end face, and leading to the seal Invalidate. For the medium that is easy to crystallize and solidify, heat preservation measures must be taken to prevent the medium from crystallizing and solidifying.　　229.html,
