Mechanical seal, also known as the end face seal, there are many advantages over the packing seal, such as saving power, reliable sealing, etc., so that the use of mechanical seals should be used as far as possible.
However, some mechanical seal life is not long, dis-assembly and packing is much more troublesome than packing seal.In this case, it not only shows no advantages, but became a drawback.Therefore, the extension of service life is one of the key issues to promote mechanical seal.
There are many factors that affect the service life of mechanical seal.Under the same conditions, different materials of the static ring, the service life is not the same.
At present, the general mechanical seal used in the static ring is impregnated resin graphite, if it is replaced by dip graphite, the service life will be much longer.
