The importance of ultra-high pressure seals for future development

Ultra-high pressure sealing problem is a very difficult problem in the industry, especially for pressure vessels and other products with high safety requirements, in addition to realizing the design function, but also pay attention to safety. In recent years, mechanical and electrical products at home and abroad are generally developing towards high pressure, high speed and high performance. Some products require hydraulic system pressure to exceed 80MPa or even reach 200MPa. This requires matching seals with ultra-high pressure resistance, long life and other properties.

ultra high pressure sealThe problem is a very difficult problem in the industry, especially for products with high safety requirements such as pressure vessels, in addition to realizing the design function, but also pay attention to safety. In recent years, mechanical and electrical products at home and abroad are generally developing towards high pressure, high speed and high performance. Some products require hydraulic system pressure to exceed 80MPa or even reach 200MPa. This requires matching seals with ultra-high pressure resistance, long life and other properties.

Because the ultra-high pressure is different with the different times, soultra high pressure sealIt also has to be linked to the times. At present, the pressure used in some industries, such as artificial diamond six-sided top press, powder metallurgy equipment, ultra-high pressure jet cutting machine, metal extrusion equipment, hydraulic forming machine and pressure test, is usually around 100MPa, and some even above 600MPa. The general high pressure seal is not more than 60MPa, but also generally short life, large leakage and other shortcomings, so the development of it can fill the gaps in this project, and will produce greater social and economic benefits.

ultra high pressure sealThe function is to prevent the leakage of hydraulic oil and ensure that the hydraulic system establishes the necessary working pressure. With its widely used in industrial machinery, mining and metallurgical equipment, automotive industry, industrial machinery, construction machinery industry, oil cylinder factory and other industries, it has increasingly highlighted its key position in economic construction. Due to the design and installation of many equipment and leak-proof requirements are different, so the product is also ever-changing.

With the continuous improvement of China's industrialization and automation level, a large number of machinery and equipment are needed to meet the needs of the development of agriculture, water conservancy, energy, transportation and other industries. These equipment need a large number of high-performance and high-reliability hydraulic pneumatic and sealing components. Moreover, the ultra-high pressure seal has a significant impact on the overall performance and service life of the mechanical equipment.
