Wind turbines radial shaft seals are rubber sealing elements installed on the shaft of wind turbines, protecting the system from environmental influences and preventing lubricating oil and media leakage. These seals are certified by ISO, ASTM, and DIN standards, providing reliable sealing, reducing friction and wear, ensuring chemical resistance, weather and UV resistance, and low friction properties. They also offer high reliability and long life, reducing maintenance needs and downtime.

Rocket engine turbo pump rubber seals

Rocket engine turbopump rubber seals are crucial components for ensuring the normal operation and sealing performance of the turbopump. They close the gap between the rotating shaft and the external environment, preventing liquid or gas leakage. These seals are made of special rubber materials with high temperature resistance, chemical stability, and corrosion resistance. The design of these seals considers sealing performance, wear resistance, high temperature resistance, chemical stability, and dimensions and geometric fit. The quality of these seals is critical to the reliability and safety of the rocket, and strict quality control and testing procedures are often adopted during the design and manufacturing process.

Axial excluder seals are crucial in wind turbines to prevent lubricating oil leaks and external pollutants from entering the generator. They are located between the main shaft and generator, protecting the bearings and components. These seals are certified by ISO 9001 and ISO 14001, the International Electrotechnical Commission (IEC), API 682, and EN 1090. They offer sealing performance, environmental protection, and reduced maintenance requirements. Made of high-performance rubber materials, they can function effectively in challenging conditions and minimize friction, heat generation, and vibration, ensuring a secure sealing effect even at high speeds.

Rubber seals for refrigeration systems undergo various tests to evaluate their mechanical properties and suitability. These tests include physical performance testing, chemical resistance testing, temperature resistance testing, expansion performance testing, seal performance testing, contact stress testing, damage and leakage testing, and contact deformation measurement. Physical properties like hardness, density, tensile strength, and tear strength are evaluated. Chemical resistance tests assess the seal’s stability and durability in specific chemicals. Temperature resistance testing ensures the seal maintains performance under extreme temperatures. Expansion performance tests simulate expansion behavior under real working conditions. Damage and leakage testing uses infrared thermal imaging and digital image correlation technology.

Main bearing seals are rubber seals on wind turbines’ main bearings, ensuring stability and efficiency. They withstand high-speed rotation and large wind amounts, preventing mechanical parts from entering the main bearing and preventing lubricating oil leakage. They also protect the main bearing from external impurities, preventing faults and reducing maintenance costs. The seals use high-performance materials and design to ensure excellent sealing performance, even under high-speed rotation conditions. They reduce main bearing failures, repair costs, and maintenance expenses, ensuring long-term stability and reliability.

Rubber seals are an essential component in refrigeration systems, protecting the components inside the evaporator and ensuring the isolation of the interior from the external environment. They are used in a variety of applications such as sealed pipe connectors, leak detectors and electric heaters. The tube sheet gasket prevents refrigerant leakage between the pipes and the tube sheet, while the leak detection port gasket ensures the sealing performance of the leak detection port. Pipe connection gaskets prevent refrigerant leakage at the outlet and inlet pipe connections, while O-rings or gaskets seal the electric heater connections. These seals have good heat resistance, chemical resistance and elasticity to adapt to temperature changes and operating conditions. They are usually located between the evaporator outlet and inlet pipes and the corresponding connecting flanges. When installing, ensure that the seals are correctly installed and tightened to ensure effective sealing performance and protect the electric heater joints from the external environment.

The yaw bearing seals not only ensures the support function of the main chassis, but also continuously rotates according to the wind direction to adapt to different wind directions. The seal is an important component of the wind turbine bearing, which prevents the leakage of grease inside the bearing and the entry of foreign matter such as external dust and rainwater.

Explosion-proof motor seals

Material:PTFE

Explosion-proof motors are designed to work in flammable and explosive environments to prevent fire or explosion caused by sparks or high temperatures. They are commonly used in hazardous environments such as chemical plants, the oil and gas industry, and mines. Various accessories such as junction boxes, ground bolts, vibration sensors, wiring seals, etc. use rubber seals to ensure safety performance and prevent contamination. Rubber seals are used at the entrance to the junction box, around the ground stud, and around the vibration sensor mounting point. Wiring sealing is also critical to prevent sparks or high temperatures at the cable outlet from causing a fire or explosion. The vibration sensor is installed at the connector, sensor head and cable outlet, with rubber seals around the head and sensor head to protect sensitive components.

One important area where rubber seals are crucial is drilling operations in the oil and gas sub-industry.
In the field of renewable energy, various products require rubber seals to function properly.
In the field of power generation, rubber seals are also an integral part of various power plant equipment such as valves, pumps, and compressors. In conclusion, rubber seals are important components used in various products in the energy industry. A reliable sealing solution can be provided.
