The design of sealing is ensuring that graphite block service life grows, and while function admirable, maintenance cost is minimized.The machinery of graphite
Preferable sealing material is made it with hot property, graphite stock material is very rigid, wear-resisting, and its suppleness can adapt to match somebody with somebody
Conjunction face, so that it is guaranteed that sealing is close.The low-friction coefficient and self-lubricating property of graphite make it be highly suitable for common lubricant not
The occasion that can be used uses, while extends the service life of graphite block；
9th, by the use of diaphragm seal combination sealing drum, it is preferably minimized the impact that graphite is subject to high temperature and particulate dust.
Sealing angle between diaphragm seal and air-cooled set makes to calculate by flow dynamics analysis, the review of fluid analysis software analysis, draws
Rational sealing angle, is conducive to diaphragm seal and changes shake the head internal flow and dust flow direction, improve sealing effect, avoid
Diaphragm seal is directly washed away by dust air-flow inside kiln hood, improves the service life of diaphragm seal.Analyzed, sealed by Engineering Thermodynamics
Piece chooses suitable wear-resisting, heat-resisting, high-tension material, ensures the sealing effect and service life of diaphragm seal；
10th, play the role of stopping high pressure draught by labyrinth seal, stop that high pressure draught directly impacts graphite grazing, reduce
The pressure at graphite position, improves the sealing effect and service life of graphite.
