High Precision Tungsten Carbide Mechanical Seal Ring Hydraulic Rings
Features of the carbon products for mechanical use
The carbon-graphite material for mechanical use is with excellent
self-lubrication; good resistance to chemical corrosion; relatively
high thermal conductivity and thermostability; sufficient
mechanical strength; and it is easy to be processed into all kinds
of geometrical shapes. It is widely used in various mechanical
equipment, such as: the equipped sealing elements of centrifugal
pump, immersible pump, chemical reaction kettle, water turbine, and
steam roster, etc; the piston ring, guide ring and lining equipped
on the compressor, oxygenerator and ammonia pump; shield electric
machine, submersible motor and the bearing of other mechanical
equipment and instruments, etc.
The precision seal-ring is made of high quality materials by an advanced process with serveral patented technologies, have very complicated shapes, high accuracy, stable mechanic properties, much higher wear and corrosion resistance, and a service life of more than twenty thousand hours in the normal case.
Applications
The cemented carbide seal-ring can be divided into both of the
kinetic seal-ring and static seal-ring, and constitutes mechanic
seal together with the spring, rubber seal-ring and steel jecket.
It will be used mainly for waste water pump, water discharge pump
for the mines, centrifugal pump, centrifuge, slag slurry pump and
slurry pump in the adverse working conditions of high speed
rotation, sand flush abrasion and corrosion. The seal-ring will be
installed on the pump body and rotating axle, and forms through the
end face of the kinetc and static ring a liquid or gas seal.
