高壓旋轉(zhuǎn)軸封-Turcon Varilip PDR rotary shaft seals
Type A - is a single lip seal suitable for use in standard industrial applications up to a pressure of 0.5 MPa (73
psi) where an elastomer radial shaft seal would be unable to withstand the temperature, friction, medium or
poor lubrication. Allows sealing at surface speeds up to 90 m/s (17,721 ft/min) with sufficient cooling and
lubrication of the sealing lip.
Type B - is the preferred choice for applications in which a high seal integrity is demanded or where
contaminated media are to be sealed. This type offers a back-up sealing lip to provide secondary sealing.
Pressure limit is 0.5 MPa (73 psi).
Type C - can be used for applications involving higher pressures for which a simple elastomer radial shaft seal
can no longer be considered. Due to reinforcement of the sealing lip, pressures up to 1 MPa (145 psi) are
possible, e.g. as pump, shaft or rotor seals.
Type D - can be subjected to pressure from both sides. Pressure differential of up to 0.5 MPa (73 psi) is
permissible. The separation of two different media using a single seal is possible. The second lip can also take
on the function of a wiper or dust lip.
Type G - is similar to Type D but has a non-contacting environmental sealing element rather than a full laydown
lip. This provides effective sealing against the ingress of dust and dirt into the system while also
ensuring torque and resulting power consumption are kept to a minimum.
Turcon Varilip PDR rotary shaft seals extend the
boundaries imposed by elastomer radial shaft seals,
utilizing advanced materials and design techniques to
provide optimum sealing performance for each
application. The outcome is a superior sealing solution,
which retains a compact seal envelope.
Standard elastomeric rotary shaft seals have a limited
application range with respect to temperature, surface
speed, media compatibility, pressure or a combination of
these due to the inherent limitations of the various
elastomer grades. Furthermore they only have a limited
suitability for applications with inadequate lubrication.
Turcon Varilip PDR rotary shaft seals are characterized in
particular by the low friction and their stick-slip-free
running, reducing the temperature generation and
permitting higher peripheral speeds.
Turcon has the characteristic of inherent memory,
whereby a distorted Turcon component will attempt to
recover to the profile it had during the sintering cycle of its
manufacturing process. This feature is used to provide the
necessary radial loading of the sealing lip onto the shaft,
negating the requirement for the energizing spring
present in elastomeric seal designs.
Turcon Varilip PDR seals are constructed from only two
parts - a precision manufactured metal body and a
mechanically retained Turcon sealing element. Unlike
seals with pressed metal cases, a gasket is not required to
provide sealing between the lip and casing. This is provided
by the mechanical retention of the lip, improving both the
chemical resistance and temperature range of the sealing
system.
Turcon Varilip PDR seals are available with a preferred
material choice of Stainless Steel 304L. Other materials such
as Stainless Steel 316L and Zinc-Plated Mild Steel are
available within the standard range. Table LXIII shows the
codes for these materials. Other specialized materials are
available on request. It should be noted that any material
other than Stainless Steel 304L will result in extended leadtime
due to stocking and / or additional process issues
