Study on Extreme Environment Adaptability of Aerospace Fluororubber Skeleton Oil Seal with Sealing Ring!

Fluororubber Skeleton Oil Seal (dshmfcom dshmfqcom) sealing ring is a sealing component that combines high-performance elastomer with metal skeleton. Using fluororubber as the base material and through a composite structure with metal skeletons (such as Q235, SS301, etc.), it achieves comprehensive performance including high temperature resistance, chemical corrosion resistance, oil resistance, etc. It is widely used in machinery, automotive, chemical, and other fields, serving as a key component to ensure equipment sealing and reliability.

I. Performance Dimensions: Characteristics Supporting Multi-Scenario Adaptation 1. Temperature Adaptability The working temperature range of Fluororubber Skeleton Oil Seal with Sealing Ring covers -30°C to 110°C. It maintains elasticity at low temperatures (e.g., still maintaining sealing performance at -30°C) and resists thermal aging in high-temperature environments (e.g., high-temperature areas of automotive engines and industrial equipment), avoiding sealing failure due to temperature fluctuations. 2. Pressure and Speed Adaptation The sealing ring has a pressure-bearing capacity of ≤0.05MPa, ensuring stable sealing under low-pressure conditions. At the same time, its design can adapt to operating scenarios with linear speeds ≤30m/s. Through optimized structure, it reduces friction and wear, ensuring sealing reliability under high-speed operation. 3. Material and Corrosion ResistanceFluororubber Skeleton Oil Seal with Sealing Ring material combination (PTFE/Q235/SS301) gives it excellent chemical corrosion resistance—PTFE (polytetrafluoroethylene) provides low friction and corrosion resistance, Q235 (ordinary carbon steel) enhances structural strength, and SS301 (stainless steel) improves corrosion and oxidation resistance. The synergy of these three ensures the long-term stability of the sealing ring in corrosive media environments (such as acids, alkalis, organic solvents).

II. Application Fields: Widespread Penetration Across Industries 1. Automotive Industry In core parts of automotive engines, transmissions, fuel systems, etc., Fluororubber Skeleton Oil Seal with Sealing Ring can withstand high temperatures, high pressure, and corrosive media (such as gasoline, lubricating oil), ensuring the sealing of fuel and lubricating oil, avoiding power transmission failures or environmental pollution caused by leakage. 2. Chemical and Petroleum Refining In chemical processes and petroleum refining equipment (such as pumps, reactors, agitators, etc.), this sealing ring can maintain sealing performance in high-temperature, high-pressure, and corrosive media environments, preventing media leakage and ensuring production safety and equipment reliability. 3. Aerospace In the aerospace field,Fluororubber Skeleton Oil Seal with Sealing Ring is applied in extreme environments such as high temperature, high pressure, and high vacuum, withstanding sudden temperature changes and pressure fluctuations, meeting the stringent requirements of aerospace equipment for the long-term stability of sealing rings. 4. Medical and Semiconductor In medical equipment (such as medical devices) and semiconductor manufacturing (such as high-cleanliness equipment), Fluororubber Skeleton Oil Seal with Sealing Ring, with its high temperature resistance and chemical corrosion resistance, ensures equipment sealing and operational stability, aligning with the industry's high requirements for materials.

III. Selection Logic: Decision Basis for Scenario Matching When selectingFluororubber Skeleton Oil Seal with Sealing Ring, it is necessary to consider working conditions such as sealing medium, working pressure, linear speed, temperature range: Sealing medium: must match the corrosiveness and chemical characteristics of the medium; Pressure: prioritize this sealing ring under low-pressure conditions; Linear speed: adapt to operating speeds ≤30m/s, ensuring friction and wear control; Temperature: cover working condition requirements from -30°C to 110°C, avoiding sealing failure caused by temperature fluctuations.
