In 2010, under the strong support of national policies, the demand for construction machinery such as excavators, loaders, bulldozers, cranes, etc. increased greatly, which drove the development of the industry. Recently, some construction machinery enterprises have successively announced the annual report of the previous year. From the annual report of the company, we can see the good performance achieved by the company in the past year. Duan Jiaxuan, a researcher in the machinery industry of China Investment Consulting, pointed out that Shanhe Intelligent's performance growth rate is quite remarkable among the companies that have published the annual report. In 2010, Shanhe Intelligent achieved a total operating income of 2.83 billion yuan, an increase of 95% over the same period of the previous year. The net profit was about 240 million yuan, an increase of 95.77%. From the perspective of Shanhe's intelligent performance growth, good profits are mainly driven by the high sales of the main product market, followed by the control of “three feesâ€. Therefore, only when the market is generally in a good environment, the company's performance will be such a big leap. Xugong, Zoomlion and Sany Heavy Industry are still in the leading position in the industry, and their performance is more prominent. During 2010, the good economic environment in the Chinese market, large-scale infrastructure construction, and the construction of energy facilities were the main forces driving construction machinery enterprises to achieve high growth, while the expansion of foreign markets also successfully contributed to the high performance of enterprises. . With the further development of the market, Chinese companies have successfully entered the high-end market, which means that the profit margin of China's construction machinery market will further expand in the future. Zhang Yulin, research director of China Investment Consulting, pointed out that from the market observation, several popular products are the basis of high profitability. In addition, the improvement of the marketing network is also a major force for leading enterprises during 2010. Not only is the marketing network in the domestic market tending to be perfect, but the network establishment in the international market is gradually on the right track. The globalization of large companies and the establishment of market diversification are quite obvious. For a long period of time in the future, the establishment of a global scale market will be a long-term trend of several major enterprises. According to the “2010-2015 China Machinery Industry Investment Analysis and Prospect Forecast Report†issued by China Investment Consulting, the industry’s “firm†has benefited from product optimization and upgrading and technological innovation in line with the market development direction. Under the development pattern, construction machinery enterprises must do a good job of products, do a good job, do a good job of the brand, and develop internationalization as a long-term goal, in order to stand firm in the international market and succeed.
 Guide Ring
Guide Ring is a mechanical seal, also known as a guide ring. It is usually made of metal or plastic and used to support and position pistons or rods. Guide Ring has excellent wear resistance and corrosion resistance, which can effectively reduce leakage and friction, thereby extending equipment life. Guide Ring is widely used in the hydraulic, pneumatic, mechanical, and automotive industries as an important mechanical seal.
The classification of Guide Ring can be divided by material, structure, and purpose. According to material classification, Guide Rings are mainly divided into metal Guide Rings and plastic Guide Rings. Metal Guide Rings are usually made of metals such as copper, iron, and stainless steel, which have high strength, wear resistance, and high-temperature resistance; The plastic Guide Ring is usually made of polytetrafluoroethylene (PTFE), nylon, polyimide and other materials, with good corrosion resistance and low friction coefficient.
According to structural classification, Guide Rings are mainly divided into unidirectional Guide Rings and bidirectional Guide Rings. A unidirectional guide ring can only withstand pressure in one direction and is typically used in hydraulic and pneumatic systems; The bidirectional guide ring can withstand bidirectional pressure and is typically used in the mechanical and automotive industries.
According to usage classification, Guide Rings are mainly divided into piston Guide Rings and rod Guide Rings. The piston guide ring is usually used to support and position the piston, preventing friction and leakage between the piston and the cylinder liner; The rod guide ring is used to support and position the rod, preventing friction and leakage between the rod and the seal.
In summary, Guide Ring is an important mechanical seal with a wide range of applications. Guide Rings with different materials, structures, and uses have their own characteristics and advantages. Choosing the appropriate Guide Ring can effectively improve the performance and lifespan of the equipment, reduce maintenance costs and failure rates.
