At present, end seal be widely used in chemical, petroleum and petrochemical industry, medical pharmacy, natural gas, paper pulp paper industry,
The field such as steel and industrial and mineral.Such as the common stirred tank of chemical enterprise, kettle is interior to have certain pressure and temperature, end seal
It is installed on agitating shaft (rotation axis), the chemical substance in stirred tank is isolated from the outside, allows chemical substance in suitable pressure
Mix and chemically reacted with temperature conditionss.
End seal realizes that sealing prerequisite condition is：Have in end seal annular seal space and be higher than confined space
0.1~0.2MPa of pressure or so and the appropriate sealing fluid of pressure stability, temperature.Wherein the effect of sealing fluid includes following two side
Face：First aspect, which is to ensure that between end seal dynamic and static ring (friction is secondary), one layer of liquid film formed by clean sealing fluid, makes
Dynamic and static ring is in non-direct contact Frotteurism, reduces dynamic and static ring friction coefficient, reduces frictional heat, improves end seal and uses
Service life.It should be noted that sealing fluid must pressure stability and higher than 0.1~0.2MPa of confined space pressure or so, exactly by
It is higher than confined space pressure in sealed fluid pressure, and liquid is always flowed from the high place of pressure toward the low place of pressure, so that
It must be clean sealing fluid to ensure to enter between end seal dynamic and static ring, thus avoid the solid matter of confined space into
Entering causes dynamic and static ring friction damage between the dynamic and static ring of end seal.Second aspect is to take away the heat and double that friction produces
Heat near the machine envelope dynamic and static ring of end face, improves the service life of machine envelope.In brief, the stabilization of sealed fluid pressure, dynamic and static ring
Between liquid film formation and end seal friction secondary nearby heat can be taken away in time is end seal stable operation
Precondition, this is to seal the precondition that liquid supply system allows for realizing.
Domestic sealing liquid supply system is mainly by the Siphon pot (sealing flow container) with cooling coil, instrument and corresponding at present
Pipeline is formed.The heat near heat and dynamic and static ring that the friction of end seal dynamic and static ring produces is supplied mainly by sealing fluid is
The natural flowing that the sealing fluid temperature difference of system different parts is formed is taken away, i.e., hot liquid rises, cold liquid sinks, heat exchange effect
Rate is low.In addition, in spite of end seal axle sleeve on carry helical blade, can suitably aid in improving heat exchange situation but total
Body heat exchange efficiency is still low.The sealing liquid supply system can meet the stabilization of sealed fluid pressure, its existing main problem and
Influence is：Heat exchange efficiency lowly causes the heat near the heat and dynamic and static ring of end seal dynamic and static ring friction generation cannot
Taken away in time by sealing fluid, and the sealing fluid overheated is unfavorable for forming good liquid film between end seal dynamic and static ring, so that
Cause the service life of end seal short, poor reliability, these are all that those skilled in the art do not expect to see.
