Carbon Seal Ring

Advantages of carbon seal ring

It has very significant advantages, and the common shape of carbon seal ring is circular. Some of it are designed in special structures such as stepped or wedge shapes according to the design of the sealing cavity.

Excellent thermal stability

It can maintain stable sealing performance within a wide temperature range of -150°C to 800°C , some high-temperature types can reach 1200°C.

Strong chemical inertness

It can withstand erosion by most corrosive media such as acids, alkalis, and organic solvents.

Extremely low friction coefficient

When paired with metals or ceramics, it can achieve long-term self-lubrication, thus reducing wear on the mating parts.

High material density

The gas and liquid permeability is low, so it has excellent sealing accuracy.

Certain elasticity and impact resistance

It can compensate for slight vibrations or coaxiality deviations during equipment operation.

Moderate thermal conductivity

It can promptly conduct the heat generated by the friction of the sealing surface, avoiding local overheating that leads to sealing failure.

Uses of carbon seal ring

In the field of fluid machinery

You can commonly use it for the shaft end seals of centrifugal pumps, vortex pumps, and screw compressors. By cooperating with metal moving rings or static rings, it prevents the liquid or gas inside the pump body from leaking along the shaft neck. Such as water, crude oil, chemical solutions and compressed air, natural gas. And it also prevents foreign substances from entering the pump chamber, ensuring the continuous and stable operation of the equipment.

In the field of power equipment

You can use it in the sealing systems of steam turbines and gas turbines, such as the shaft seals and diaphragm seals of steam turbines. It can withstand the erosion of high-temperature and high-pressure steam and improve the thermal efficiency of the unit.

You can also use it in the sealing vanes of generators to prevent hydrogen leakage. It can maintain an inert environment inside the generator.

In the automotive and rail transportation fields

Carbon seal ring is suitable for the sealing of automotive water pumps and gearboxes, as well as the shaft end seals of subway and high-speed rail traction motors. Because it can withstand high and low temperatures and resisting vibration, it can adapt to the complex working conditions during vehicle operation.

In the field of precision machinery

You can also use it for the rotor seals of vacuum pumps and the vacuum seals of semiconductor manufacturing equipment. With their low leakage rate and high sealing performance, you can use it lithography machines. It can meet the requirements of ultra-high vacuum environment which ensures the precision of precision processing.
