Precise Technical Parameters
Carbon floating ring seals are engineered with measurable performance metrics to meet industrial sealing demands. They operate within a pressure range of 0.1 to 2 MPa, suitable for medium-pressure scenarios like chemical compressor systems and high-pressure air handling in manufacturing. The temperature tolerance spans from -40℃ to 500℃, adapting to low-temperature refrigeration equipment and high-temperature steam systems alike. The maximum linear speed reaches ≤150 m/s, ensuring stable sealing even under high-rotation conditions of centrifuges or compressors. These seals fit shaft diameters from 25 mm to 500 mm, covering small-scale mixers and large industrial blowers. They are widely applicable to key equipment including blowers, centrifuges, mixers, vacuum equipment, and compressors.
Core Design Highlights
● Split Carbon Ring Structure
This design adopts multi-stage grouped carbon rings. The outer ring uses carbon material for tight wrapping to ensure sealing integrity, while an embedded titanium alloy reinforcement ring boosts compressive strength-critical for withstanding pressure fluctuations in industrial systems. Cone surface matching fixing technology streamlines installation, reducing setup time compared to traditional seal structures.
● Bidirectional Fluid Isolation Technology
Multi-stage carbon rings are arranged alongside isolation gas (such as nitrogen) injection to form a bidirectional dynamic barrier. This barrier effectively blocks medium leakage, making the seals ideal for toxic, flammable, or high-purity gas environments like chemical plants handling hydrogen or ammonia.
● Dust and Granular Media Adaptability
An optional comb seal assembly is available to prevent solid impurities from entering the gap of the split carbon ring seal with isolation gas. This prevents abnormal wear of the carbon ring and shaft, extending the seal's service life by reducing friction and damage from particles.
● Axial-Free Installation and Fast Maintenance
The split cavity structure allows direct radial disassembly and assembly without removing the equipment spindle. This significantly shortens downtime for maintenance, a key advantage for continuous-operation equipment like production-line centrifuges or blowers.
● High-Precision Dynamic Compensation
The floating carbon ring design adapts to micron-level shaft system offset and pressure fluctuations. This ensures consistent sealing stability even when equipment operates at high speeds or under variable loads, avoiding seal failure from minor mechanical deviations.
Performance Advantages
Resistant to Extreme Environments
The carbon graphite material offers self-lubrication, eliminating the need for additional lubricants in harsh conditions. Paired with corrosion-resistant titanium alloy structural parts, the seals handle temperatures from -40℃ to 500℃, maintaining performance in both cold storage vacuum equipment and high-temperature steam systems.
Zero Leakage Guarantee
Isolation gas film works with multi-stage throttling and pressure reduction to create physical isolation between the medium and external environment. This results in a leakage rate close to zero, meeting strict standards for high-purity gas handling or toxic medium containment.
Safety and Compliance
Inert gas isolation technology ensures the seals meet explosion-proof and environmental protection requirements for flammable, explosive, toxic, and harmful media. This compliance is essential for industries like petrochemicals or mining that handle hazardous substances.
Industry-Specific Solutions
● Chemical Compressors
Nitrogen isolation is used to contain high-pressure flammable gases such as hydrogen and ammonia, eliminating leakage risks that could lead to safety hazards or product loss.
● High-Temperature Steam Equipment
The seals maintain stability in 500℃ steam environments, reducing heat loss by preventing steam leakage-critical for energy efficiency in power generation or heating systems.
● Dust Environment Machinery
When combined with comb seals, the seals block dust from entering the sealing chamber. This makes them suitable for metallurgy, cement, and other industries where dust is a common operational challenge.
