1. Mechanical Engineering
Bearing seal: Bearings are key components in mechanical equipment and need to be sealed to prevent lubricant leakage and ensure long-term effective operation of bearings.
Sealed box: Sealed boxes require seals to ensure the safety of parts in the box and the stability of mechanical equipment.
Valve seal: Valves are crucial in fluid control systems, and seals are used to ensure the normal use of valves and prevent medium leakage.
2. Automobile industry
Engine seal: The engine is the heart of the car and requires a variety of seals to prevent oil-water mixing, gas leakage, etc.
Body seal: The body needs to be sealed to effectively isolate noise, dust and vehicle exhaust emissions inside and outside the car.
Part connection seal: Rubber seals are most commonly used in the connection parts of mechanical parts to prevent paint and oil leakage.
3. Electronics industry
In the electronics industry, seals are mainly used to protect the internal parts of electronic products to prevent corrosion and damage to internal parts by dust, moisture, oxygen, etc. For example, mobile phones, computers and other products use seals to isolate and protect some components.
4. Aerospace
Due to the special working environment, aerospace seals have high requirements for materials. For example, fuel tank seals need to consider whether the material can resist fuel corrosion, as well as its high temperature resistance, pressure resistance, vibration resistance, and service life. Aerospace seals can be widely used in engines, flight control systems, brake systems, fuel tanks, landing gear systems, cockpits, fuselage structures and other fields.
5. Shipbuilding
Shaft system seals: Ship propulsion systems, auxiliary machinery, steering gears and other equipment require shaft systems for transmission. In the shaft systems of these equipment, seals are used to prevent leakage of media such as water, lubricating oil and gas.
Cabin seals: Cabin seals are mainly used for watertight and airtight separation of the hull. These seals can prevent water from entering the living area and equipment compartments in the ship, and can also ensure that the air in the ship is sealed to prevent external gas from entering.
Pipeline seals: In the ship's pipeline system, seals are used to connect various components and prevent medium leakage.
6. Medical devices
In the field of medical device manufacturing, seals need to ensure the sealing and hygiene of medical devices and meet the strict requirements of the medical industry for material safety. For example, artificial heart valves, hemodialyzers, etc. require seals with good biocompatibility.
VII. Special environments
High temperature environment: Seals in high temperature environments need to have high temperature resistance, corrosion resistance and stability to ensure the normal operation of the equipment.
High pressure environment: Seals in high pressure environments need to have high strength and high pressure resistance.
In addition, seals also play an irreplaceable role in industries such as petrochemicals, coal chemicals, metallurgy, pharmaceuticals, food, and textiles. They are widely used in various equipment and systems to ensure the smooth progress of the production process and the safety and quality of products.
In summary, the application scenarios of seals in industrial production are very wide and diverse. They ensure the normal operation and safety of various equipment and systems by providing reliable sealing performance.
