Features
1. Medium resistance: Rubber U seal can withstand a variety of media, including petroleum, chemical raw materials, hydraulic oil, etc. This makes it widely used in a variety of industries.
2. High and low temperature resistance: Depending on different material selections, rubber U-shaped seals can work in high and low temperature environments. For example, high-performance materials such as fluororubber can maintain good sealing performance at high temperatures.
3. Anti-aging performance: Rubber U-shaped seals are not prone to aging after long-term use and can maintain good sealing performance.
4. Environmental protection: The material selection of rubber U seal usually takes environmental factors into consideration. The use of environmentally friendly materials can reduce the impact on the environment.
Applications
1. Hydraulic system: In the hydraulic system, rubber U seal can seal the hydraulic oil, prevent oil leakage, and maintain system pressure stability.
2. Automobile industry: In the automobile industry, rubber U-shaped seals are widely used in engines, hydraulic systems and other parts. They can seal engine oil, hydraulic oil, etc. to ensure the reliability and safety of automobiles.
3. Food industry: In the food industry, rubber U-shaped seals can be used in food processing equipment to seal food and ensure food safety and hygiene.
4. Medical industry: In the medical industry, rubber U seal can be used in medical equipment, such as infusion tubes, syringes, etc., to seal medicinal liquids and ensure the safety of the medical process.
Sealing principle
A rubber U seal is a seal made of elastic material that is shaped like the letter U. Its sealing principle is based on the elastic deformation of the material. When the U-shaped sealing ring is installed in the sealing groove, its two boundaries are compressed to form a sealing interface. Because the U-shaped seal has a good surface structure, it can maintain good lubrication when sliding on the metal surface, reduce friction and wear, and improve performance. Under low pressure, the U-shaped sealing ring has a good sealing effect by pre-pressuring the lip; while under high pressure, it has a self-sealing effect.
Special Aspects
1. Environmentally friendly and non-toxic: Rubber U seal are usually made of environmentally friendly materials and will not cause harm to the environment and human body.
2. Good resilience: The rubber U-shaped seal has good resilience and can maintain a stable sealing effect during the operation of the equipment.
3. Medium resistance: Rubber U-shaped seals can withstand a variety of media, including petroleum, chemical raw materials, hydraulic oil, etc., so they are widely used in a variety of industries.
4. Dynamic sealing performance: Rubber U seal have good dynamic sealing performance and can maintain a stable sealing effect during equipment operation.
5. Wear resistance: Rubber U-shaped seals have certain anti-wear properties, which can maintain a stable friction coefficient between friction pairs and reduce wear.
6. Strong customizability: Rubber U-shaped seals can be customized according to different needs, such as material, size, shape, etc., to meet various design and use requirements.
Craftsmanship
1. Ingredients: Mix rubber and other raw materials together in a certain proportion.
2. Rubber mixing: Put the mixed raw materials into the rubber mixing machine and refine them through high temperature and high pressure to achieve the required performance requirements.
3. Cutting: Cut the refined rubber material into strips or blocks of a certain length and width.
4. Mold pressing: Put the cut rubber material into the mold and press it through high temperature and high pressure to make it into the required U-shaped shape and size.
5. Vulcanization treatment: Put the pressed rubber U-shaped seal into a vulcanization furnace for vulcanization treatment to improve its physical and chemical properties.
6. Testing and packaging: Test the vulcanized rubber U-shaped seals, such as size, hardness, pressure resistance and other properties, and package them after passing the test.
