CR V shaped seals are high quality sealing solutions, CR V-ring seals are used to prevent leaks and contamination in critical applications.CR V-ring seals are a kind of rubber seals for reciprocating motion. The cross-section is V-shaped, and it is seldom used alone. It is generally used in combination with a pressure ring with cloth fabric, a support ring and several V-shaped sealing rings. The number of sealing rings depends on the sealing pressure.

 

機能

CR V shaped seals are designed to provide a dynamic sealing solution for rotating shafts. These seals consist of a V-shaped profile made of high-quality elastomeric material such as nitrile rubber (NBR) or fluoroelastomer (FKM). NBR and fkm used in making seals can support protective for equipments ,also chemical tools.

Advantage:

1. Excellent sealing performance: CR V shaped seals have excellent sealing ability to prevent the ingress of contaminants and the leakage of lubricants or liquids.
2. Versatility: These seals are suitable for a wide range of applications including pumps, gearboxes, electric motors and other rotating equipment. They are used in various industries such as automotive, aerospace, oil and gas, and manufacturing.
3. Ease of Installation: CR V-ring seals are designed for easy installation, reducing downtime during maintenance or replacement. V-rings are easily stretched over the shaft and positioned where desired for a secure fit.
4. Cost-effective solution: By preventing leaks and contamination, CR V shaped seals can extend the life of equipment and reduce the need for frequent repairs or replacements.
5. Resistant to extreme conditions: Seals are engineered to withstand extreme temperatures, chemicals and pressure. The elastomeric material used in its construction has excellent resistance to oils, greases, water and other liquids, ensuring reliable performance in harsh environments.

Application:

CR V shaped seals are used in a variety of industries and equipment, including but not limited to:

1. Automotive: These seals are commonly used in engines, transmissions and differentials to prevent oil leakage and contamination, ensuring optimum performance and reliability.
2. Aerospace: CR V-ring seals are used in aircraft engines, landing gear systems and hydraulic systems to provide effective sealing for key components.
3. Oil and Gas: These seals are suitable for sealing the rotating shafts of pumps, compressors and valves used in the oil and gas industry. They help prevent fluid and contaminant spills, ensuring safe and efficient operations.
4. Manufacturing: CR V-ring seals are widely used in manufacturing equipment, including mixers, conveyors and rotary kilns. They provide a reliable seal that prevents dust, dirt or moisture from entering the device.

A V-seal is a type of elastomeric seal used for sealing operations. It is widely used in fields such as mechanical engineering, automobile industry, construction, chemical industry, food processing and pharmaceuticals. Made of high-quality elastic material, it has high temperature resistance, pressure resistance, abrasion resistance and chemical corrosion resistance. The V-shaped groove is adopted in the design, so that the seal can well adapt to grooves of different sizes and shapes, ensuring the stability and reliability of the sealing work.

The V-shaped seal has a compact structure, is not easily deformed, and has high safety and reliability. It can be widely used in a variety of fields with sealing requirements, such as in piping systems, fluid conveying pipelines, hydraulic machinery, steam turbines and generators and other equipment.

In terms of product production, we adopt the most advanced production process and technology to ensure the stable quality and performance of each V-shaped seal.
