Emergency repair methods for high-pressure hoses: 1. Sticky repair method When the rubber hose with the pressure of the hydraulic system between 25-8.0MPa breaks, the sticky repair method can be used: wipe the area around the rupture of the hose; Apply one of anaerobic glue, epoxy resin glue, 801 glue or 502 glue to the rupture (the length of the glue is about 2-3 times the length of the rupture); 4-5 layers of glue; tie the two ends of the canvas strip with the wrapping tape into dead knots; it can be used after it has solidified. On the day of the establishment of the military enterprise certification department, Litong Company conducted professional training and research on the relevant R&D personnel, mainly to keep the R&D and manufacturing completely confidential, and not to disclose any information about the products. Chinese jobs should handle military orders with stricter working conditions. Strict quality control and absence of defects are minimum standards for the production of military products. Obtaining the certification of the military company marks the new development of Litong in new fields. Litong pursues more breakthroughs in the steady development, and constantly creates one miracle after another on the basis of the original development, breaking through one difficulty after another. Since January 2017, Litong has successfully developed Super Hercules series of fluid hoses, ultra-durable cleaning hoses, drilling and oil pipelines, and PTFE/HNBR hose “KING HOSE” series, and achieved excellent results. We have gradually become the leader of the international advanced hydraulic hose manufacturer, constantly pursuing progress and innovation! Founded in 2003, the company has developed into a large-scale enterprise with an annual output value of 300 million yuan in just ten years. In 2019, it continued to invest in the introduction of high-end production equipment and experimental equipment, adhering to high-end and insisting on innovation. Litong Hydraulic Technology Co., Ltd. has 36 scientific and technical personnel, including 2 professors, 2 doctoral students, 6 senior engineers and 26 engineers. Litong owns the CNAS-Henan Laboratory High Pressure Rubber Hose Engineering Technology Research Center, and jointly established the Litong Qingdao Research Institute with Qingdao University of Science and Technology.
Asphalt hoses are generally used for loading and unloading hot asphalt. The pipes are designed to withstand positive and negative pressure. In addition to the normal reinforcement layer, there is also a layer of spiral steel wire to support the pipe body. When negative pressure occurs during loading and unloading, the pipe will not be damaged. Press plaque. In addition to synthetic rubber, the inner rubber can also be made of PTFE. The outer rubber layer has the characteristics of weather resistance and wear resistance. There are various forms of asphalt hose joints, and customers can assemble different joints according to different use environments. In theory, the inner rubber layer of the ultra-high pressure resin tube is absolutely oil-resistant, and there is basically no corrosion of the rubber layer by oil, so after the precise withholding, the hose should not leak oil or fall off the head, etc. phenomenon. . This problem was solved after the application of the endoscopic measurement technology adopted by many manufacturers. In addition, the bending radius of the ultra-high pressure resin pipe is generally larger than that of the traditional high pressure rubber pipe, which also affects the design and construction.
