Mechanical Seal Ring and Method

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention relates to a slide ring seal ring (mechanical seal ring) that comprises at least one ceramic region containing 30-70% by volume of an iron-silicon-chromium alloy (FeSiCr). The patent also describes a method for manufacturing such seal rings by forming a composite material with FeSiCr, silicon carbide (SiC), and silicon oxycarbide, improving the seal ring's wear resistance and cost-effectiveness. The production process is efficient, and the created seal ring provides a balance of hardness, strength, and toughness suitable for industrial applications.

Use CasesContent extracted from patent full text and abstract with AI.

• Mechanical seals in pumps for water, chemicals, or oil processing industries.
• Sealing solutions in rotating machinery such as compressors, mixers, and turbines.
• Automotive and aerospace equipment requiring reliable rotary shaft seals.
• Industrial process equipment where durable and long-lasting seals are required.

BenefitsContent extracted from patent full text and abstract with AI.

• High wear resistance and long operational life compared to traditional ceramic seals.
• Cost-effective manufacturing due to adaptable processing methods and reduced tool wear.
• Customizable hardness and toughness based on material composition for application-specific needs.
• Lower material and production costs due to use of FeSiCr and silicon-based binders.
• Ability to use more affordable machining tools (like boron carbide) during finishing, reducing overall production expense.
• Consistent and reliable sealing performance in demanding industrial environments.
