Mechanical seals
These mechanical seals are designed for use
under severe service conditions at relatively
low peripheral speeds. They offer reliable
protection against solid and liquid
contaminants as well as leak-proof retention
of lubricant. The seals were originally
developed for off-road and tracked vehicles
but have been found to be equally suitable for
a range of other applications where effective
protection is required against sand, soil, mud,
water etc. These applications include
N all types of mixers,
N sand treatment equipment,
N conveyors and other construction
equipment,
N agricultural machinery,
N washing equipment,
N grinding mills and other comminution
equipment,
N ore dressing equipment, and
N mining equipment.
Fig 84
The mechanical seals from SKF (fig 84)
consist of two identical sealing rings and two
similar nitrile rubber Belleville washers (cup
springs). The sealing rings are of wear and
corrosion resistant steel and have finely
finished sliding and sealing surfaces. Sealing is
assured even against thin oils, such as SAE
10W40 oils. The Belleville washers of nitrile
rubber provide the necessary uniform face
loading and positive sealing at the bore and
outside diameters. The outside diameter of the
washers adapts to the form of the bore in
which they are mounted and there are no
special demands in respect of surface finish.
