1. Nuclear power industry
Ultra large diameter mechanical seals have important applications in the nuclear power industry. With China's nuclear power equipment research and development technology reaching the international advanced level, the installed capacity of nuclear power continues to grow. By the end of 2023, the cumulative installed capacity of nuclear power in China will reach 56.91 million kilowatts, a year-on-year increase of 2.4%. In various equipment of nuclear power plants, such as reactor coolant pumps and other rotating fluid machinery, it is necessary to prevent internal fluid (such as coolant) leakage. As the shaft sealing device of rotating fluid machinery, ultra large diameter mechanical seals can meet the sealing requirements of these equipment and ensure the safe and stable operation of nuclear power plants.
2. Chemical industry
The chemical industry is also a major application area for ultra large diameter mechanical seals. The scale of China's chemical industry continues to expand, with over 30000 enterprises above designated size by 2023, and many old production capacities requiring equipment updates. In chemical production, centrifugal pumps, reaction vessels, compressors, centrifuges and other equipment are widely used. These devices need to prevent internal chemical fluid leakage. Ultra large diameter mechanical seals, with their excellent sealing performance, can be applied to these devices to ensure the normal operation of chemical production.
3. Other possible application scenarios
From the perspective of expanding the general application areas of mechanical seals, ultra large diameter mechanical seals may also be applied in some large-scale fields such as water conservancy engineering and marine engineering. In large water pump stations of hydraulic engineering, ultra large diameter mechanical seals may be used to prevent water leakage; In some large offshore platform equipment in ocean engineering, such as seawater circulation pumps, ultra large diameter mechanical seals may also be used to achieve sealing function.
