â‘ Hardness:
Due to the scientific synthesis of high-molecular polyurethane elastomer materials using iron rubber, the higher the hardness, the higher the modulus, the smaller the elongation, and the better the wear resistance and heat resistance. Well, in the range of minus 35 degrees Celsius to 100 degrees Celsius, and at a pressure of 60 to 70 MPa, the maximum sealing performance can be guaranteed.
The use of viscoelastic seals made of nitrile rubber is the most complete protection against damage caused by back pressure. In the range of minus 55 degrees Celsius to 100 degrees Celsius, and under a pressure of 21MPa, due to the rubber The seal is often in a compressed state, so the compression performance of the rubber seal must be considered. It not only achieves enhanced anti-climbing performance and low friction resistance, but also has good performance in dealing with special low-temperature oil, and can also be used in combination with Anti-wear Ring double-purpose retaining ring BRL type.
Sealing products made of polytetrafluoroethylene and nitrile rubber/PTFErubber; or seals made of nylon resin and nitrile rubber, which can be used in a wide range of applications with large pressure changes and fast sliding speeds According to the working condition, the input hydraulic pressure cutout is designed on the end face of the polytetrafluoroethylene ring to prevent penetration leakage. The maximum working temperature environment is minus 40 degrees Celsius to 160 degrees Celsius; the maximum working pressure is 50MPa.

Mechanical basic components mainly refer to: bearings, gears, molds, hydraulic components, pneumatic components, seals, fasteners, etc., are an indispensable part of the equipment manufacturing industry, directly determine the performance of major equipment and host products, Level, quality and reliability.
The "plan" proposes to adopt a three-year effort to break through the bottleneck in the development of a number of key components and components in areas such as energy development, transportation, new rural construction, new material preparation, energy conservation, environmental protection, and comprehensive utilization of resources.
The "Proposal" also proposes to cultivate 100 enterprises with large scale, high professionalism, distinctive characteristics, and well-known brand products. Attract multiple capital investments in the basic components industry. Relying on existing resources, it has increased support and guidance for existing industrial agglomerations such as bearings, gears, hydraulic parts, seals, and fasteners, and has guided enterprises to gather in industrial parks to strengthen the concentration of castings, forgings, and heat treatment in clusters. To produce and nurture a group of special industrial agglomerations with specialized division of labor, industrial chain coordination, and sales revenue exceeding RMB 10 billion. Support provincial and municipal construction of provincial bases for new types of industrialization demonstration bases, and encourage the construction of a number of state-level basic parts and components “a new type of industrialization demonstration base†in a conditional agglomeration area.

Recently, the Ministry of Industry and Information Technology has issued the Implementation Plan for the Revitalization of the Mechanical Basic Components Industry, and plans to increase the supporting capacity of China's major equipment basic components to more than 70% through three years of efforts. Encourage enterprises to cross-industry, cross-ownership mergers and reorganizations, and strive to form a number of enterprise groups with international competitiveness and annual sales of over 5 billion yuan. The implementation period of the plan is from 2010 to 2012.
