Usually the running speed with values of <0.1m/sec
is low, the load however can exceed 150 N/cm2
Due to the resulting friction heat, the
temperature in the sealing gap may exceed the saturation
point Of the steam and consequently there will be dry running.
It is therefore recommended to avoid setting the
load to high and to accept a slight leakage of the non-toxic
Spring load: 1-3 N/ cm2
rings for radial seals
Because of their
characteristic properties car-carbon/graphite sealing rings
have been successfully used for many years in radial seals,
both with rotary and oscillatory motions.
Apart from carbon
sealing rings encased in metal, multi-part carbon sealing
rings composed of segments are mainly used for radial
