Carbon Graphite Materials
|
Carbon Graphite
Materials are proven applications for the sealing of shafts
and their
bearing. These rubbing components are widely used in high
temperature applications
where the presence of liquid lubricants is unacceptable.
What makes SIV SEAL suitable for the most demanding
application? A combination of high temperature withstand,
chemical inertness, dry running capacity. low density
dimensional stability, impermeability to gas and liquid as
well as low thermal
co-efficient of expansion. |
Grade |
Manufactured Carbon differs in
character from most other materials because of the
nature of its composite granular structure, in consequences,
the figure quoted below
are typical values and allowance must be made a for the
variability obtainable between individual measurements. |

Carbon Vanes,
Rotors and End Plates |
Due to the
unique properties of carbon, it is ideal for oil free
applications and for use with most chemical, petrol paraffin
and fuel oils. Vanes, Rotors, End Plates and housing made in
carbon are fitted in gas pumps, with compression or vacuum
duties and vane pumps for most type of fluids.
Typical Industries-Chemical industries, food industries
medical equipments, dispensing equipment.metering equipment
and vending machine.
Grade Selection-it is important to seek further help
concerning correct grade selection from our technical
department. |

Carbon Sleeve Bearings |
Carbon sleeve
bearing are employed where
oil lubricated bearing cannot be used. Carbon, with its good
dry running ability together with excellent corrosion
resistance, form retention and resistance to high temp. and
sudden temp changes as well as good thermal conductivity,
possess an outstanding combination properties for these
application.carbon bearing can be pressed into a process of
h7/s6 for operating temperature of upto 1500c.
the housing or steel ring should be heated upto about 4500c.
the housing or steel ring should be heated upto about 4500c
for shrinking in. |

Packings
Rings |
|
Packing rings are divided into
two types :
Those with shaft clearance (with gaps) and
those in contact with the shaft. The contact pressure of the
carbon ring to the cylinder
is necessary to achieve. A good sealing effect is attained
with the use of garter spring, Calculation of spiral tension
spring can be
based on maximum permissible contact pressure of the carbon
ring on the cylinder of
1.........1.5n/cm2 |

are provided with carbon packing ring pressed
laterally onto the steam inlet and outlet vents having concave
or convex surface, because this design allows the packing ring
to adjust to the
oscillation of calender drums. Carbon seal attain the surface
quality necessary for sealing after a short running in period. |

Mechanical
Shaft Seal Face |
Mechanical seals
are mainly used for high speed sealing between liquids and
two gases the two surface aids the lubrication of the two
surface, conduct heat caused by friction and improve the
sealing effect. The diameter of the counter face should be
the same or larger than that of the carbon ring. the finish
of the carbon wearing surface and of the counter face is
critical to the relative wear rate. Counter face : Grey cast
iron, plain, steel alloyed steel hard
metal, ceramic, glass, tungsten carbide, silicon carbide. |
|
Mechanical
Shaft Seal |
|
Is
impervious to practically all known acids, solvents &
corrosives. permits the handling of
inflammables and toxic with absolute safely due to complete
elimination of leakage. prevents loss of expensive liquids
and gases. Siv Seal is available in various range of styles
and sizes, can
meet space and installation requirements for practically all
types of rotary shaft equipments like centrifugal and rotary
pumps, mixtures, agitators and autoclaves. special types of
seals
can be recommended for handling medium/high
pressures and temperatures.
Spares-Carbon : Metallic and flexible member-can be
had ex stock at all times. |
