The integral carbon ring seal is a high-performance, multi-stage, non-contact shaft seal designed specifically for high-speed rotating equipment such as centrifugal compressors, screw compressors, and screw steam expanders. It employs a valve-type carbon ring multi-stage layout and nitrogen buffer isolation technology to achieve zero-pollution, low-leakage sealing under clean media conditions. This provides stable, reliable, and long-life sealing for high-speed rotating equipment, making it a core sealing component for industrial fluid machinery and energy power equipment.
Core Design Features
- Valve-type Carbon Ring Structure: Utilizing precision-machined valve-type carbon ring seal components, it boasts strong self-adaptability, automatically compensating for shaft movement, eccentricity, and vibration, ensuring consistent sealing surface contact and stable sealing performance.
- Exhaust + Dual Inflation Design: Integrates both venting and inflation structures, flexibly adapting to different working conditions and enabling precise control of the sealing gas, while also providing a channel for buffer gas injection.
- Safe Leakage Handling: Leaking gas can be safely discharged or directly connected to a low-pressure recovery system, eliminating safety hazards and environmental pollution caused by media leakage, meeting environmental protection and safe operation requirements.
- Multi-Stage Low Leakage Layout: Multi-stage carbon flow series layout significantly reduces media leakage while extending seal life, improving seal reliability and economy.
- Modular Container Structure: Adopts a container-type integrated structure for easy installation and… Easy disassembly and simple maintenance significantly reduce on-site operation and maintenance difficulty and cost.
- Nitrogen buffer isolation technology: After the medium leaks through multiple stages of carbon flow, nitrogen is used as a buffer isolation gas to achieve bidirectional isolation between the medium and lubricating oil, preventing the medium from contaminating the lubricating oil and the lubricating oil from entering the device. Perfectly suited for clean medium operating conditions.
Core operating parameters
- Applicable temperature: -40℃~200℃, wide temperature range coverage, suitable for low temperature, normal temperature, and medium-high temperature operating environments.
- Working pressure: 0~2MPa, suitable for stable sealing requirements under medium and low pressure conditions.
- Allowable linear velocity: ≤140 Meters per second, meeting the sealing requirements of high-speed rotating equipment.
- Compatible shaft diameter: 25~400 mm, flexibly adaptable to different specifications of rotating equipment shaft diameters.
Core product advantages
- Two-way isolation, clean and contaminant-free
Using nitrogen as a buffer and isolation medium, it achieves complete isolation between process media and lubricating oil. The media will not contaminate the lubricating oil, and the lubricating oil will not enter the equipment. It is perfectly adapted to clean media conditions, ensuring the purity of the media and the cleanliness of the equipment.
- Multi-stage sealing, ultra-low leakage
The multi-stage carbon ring series layout significantly reduces media leakage. The sealing performance far exceeds that of ordinary seals, while extending the seal service life and reducing maintenance costs.
- High-speed adaptation, stable operation
Adaptable to linear velocities up to 140 m/s, capable of withstanding high-speed rotating conditions. The valve-type carbon ring structure automatically compensates for shaft vibration and axial movement, ensuring smooth and uninterrupted operation and continuous and stable equipment operation.
- Safe and environmentally friendly, compliant and reliable
Leaked gas can be safely discharged or recovered, eliminating safety hazards and environmental pollution, complying with industrial safety and environmental protection standards, and adaptable to various harsh operating conditions.
- Easy Installation and Maintenance
Modular container structure, simple installation and disassembly, convenient maintenance, significantly reducing on-site operation difficulty and downtime.
- Strong Adaptability to Wide Operating Conditions
