The high-temperature and low-pressure oil hose winding technology used in the hydraulic system of construction machinery was finally broken by the monopoly of companies in Japan, Europe and the United States. Recently, the news came from the engineering machinery hose factory in Hebei Cangzhou City. After nearly 5 years of research and development, the factory has opened up a new high-temperature low-pressure oil pipe winding production process and has applied for national invention patents.
In recent years, the rapid development of China's construction machinery manufacturing industry has also led to a rapid increase in the demand for mechanical hoses. However, due to the special design of the hydraulic system of the construction machinery, especially the working conditions of the construction machinery are poor, the temperature is high and low, and the requirements for the weather resistance and oil resistance of the supporting high temperature and low pressure oil hose are also higher. The higher it is. The ordinary oil hoses produced in China cannot meet the requirements, and most of them are imported from Japan and other countries. Hebei Luzhou Engineering Hose Factory promotes product innovation with scientific and technological innovation. Since 2001, it has been developing new high-performance high-temperature and low-pressure oil-wound hose production technology, and has been included in the Hebei Science and Technology Research Project and the National Development and Reform Commission's key support project.
According to reports, the product has the characteristics of high tear strength and long service life. Its high temperature resistance reaches 120 °C, which is more than 20% higher than similar products; the breaking strength reaches 6.9Mpa, which is 14.8% higher than similar products; the inner and outer rubber layers The elongation at break is 315% and 363%, respectively, which is 20% higher than similar products. The product quality and process technology are at the domestic leading level, and the use temperature has reached the international advanced level. Especially because the product has good physical properties, it can fully meet the needs of engineering machinery products in different regions and environments, and can be widely used in high temperature of hydraulic systems of large-scale bulldozers, loaders, cranes, excavators, etc. Low pressure oil pipeline.
It is understood that the new technology for producing high-performance high-temperature and low-pressure oil-wound hoses overcomes many problems that could not be solved in the production process of the woven fabrics in the past. The wound hoses produced not only have the pressure change rate and burst pressure. Obvious advantages, and more automated and controllable. At present, the product has been applied in more than ten domestic construction machinery manufacturers such as Xuangong and Xugong, all of which show excellent characteristics.
