Construction Machinery hydraulic system used in high-temperature low-pressure oilHose winding process technology from Japan, Europe and America in countries such as corporate monopoly was finally broken. In recent days, from Hebei Jizhou City Engineering Machinery Rubber Hose Factory came news of the plant after nearly five years of research and development, independent innovation has opened up a new production of the new high-temperature low-pressure pipeline winding process and has applied for national patent.
However, due to construction machinery hydraulic system design specificity, particularly in construction engineering machinery harsh working conditions, the temperature high and sometimes low, for matching with the high-temperature low-pressure oil hose weather resistance, oil resistance and other performance indicators requirements higher and higher.While the domestic production can not meet the requirements of ordinary oil hose, mostly imported from Japan and other countries. Rubber Hose Factory, Hebei Jizhou City works to promote scientific and technological innovation product innovation, since 2001 began the development of high-performance high-temperature low-pressure oil hose wrapped production of new technology, and is included in the Hebei Province scientific and technological research projects and key support for the State Development and Reform Commission项目.
According to reports, the product has a high tensile strength, long life and other characteristics, its high temperature performance to 120 ℃, compared with similar products increased by 20% or more; tensile strength to reach 6.9Mpa, compared with similar products increased by 14.8%; internal and external layer elongation at break were 315% and 363%, compared with similar products for more than 20% increase in product quality, process technology, ranking the leading domestic level, using the temperature reached the international advanced level. Especially since the product has excellent physical characteristics, can fully meet the different areas and under different environmental and engineering machinery products matched the needs, can be widely used in large-scaleBulldozer、Loader、Crane、ExcavatorConstruction machinery such as high-temperature low-pressure hydraulic system pipelines Rd.
It is understood that production of high-performance high-temperature low-pressure oil hose wrapped in adopting a new technology to overcome the past, using woven craft production process can not solve the many problems, the production of the winding tube is not only the rate of change in pressure, burst pressure and other indicators has obvious advantages, but also the degree of automation and control more. At present, the products have been successively declared workers, Xugong a dozen other domestic engineering machinery manufacturing applications, are indicative of the excellent features.
