The wide application of hydraulic hose and the processing requirements of hydraulic hose joints

A small hose, connected to the vast world of engineering construction - this hose is talking about hydraulic pipes.Hydraulic hose is widely used in engineering constructionHydraulic hose alias hydraulic oil hose, hydraulic flexible hose, high pressure hose, wire high pressure hose, steel wire braided hose and steel wire spiral hose, generally divided into wire braided hydraulic hose and wire spiral hydraulic hose.Mainly used in mine hydraulic support, oil field mining, Suitable for engineering construction, lifting and transportation, metallurgy and forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and various industrial departments mechanized, automated hydraulic system transport with a certain pressure (high pressure) and temperature of petroleum (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsion, oil-water emulsion, water Etc and liquid transmission, the maximum working pressure can be up to 60MPa. As a general basic component of manufacturing industry, hydraulic products are widely distributed in downstream industries. The downstream industries of hydraulic products in China are mainly construction machinery, automobiles, heavy machinery, machine tools, etc., of which construction machinery accounts for 44%. It can be seen that where there is engineering construction, there must be a large number of hydraulic hose applications, and in the current period of rapid development of large-scale infrastructure, the market for hydraulic hose is very broad.Hydraulic hose segment market situationThe United States, China, Japan, Germany and Italy are the top five countries in global hydraulic sales, of which China accounts for 30.2% and the United States accounts for 38.0%. According to MarketsandMarkets, the global market is expected to reach 290.4 billion yuan by 2025, and the proportion of key components represented by oil cylinders, pumps and valves in the domestic market is relatively high, and the import dependence of China's hydraulic market is gradually decreasing.In the hose market segment of the hydraulic system industry, most of the hydraulic hose in the middle and high-end market are occupied by imported brands, and there are also large-scale production bases in China, and the market feedback speed is also doing better. Although domestic brands have made great progress in recent years, the technology is still in a state of follow-up, and many standards and manufacturing processes are also referred to foreign enterprises. The market is mainly the low-end market, and it will take some time for the high-end market to replace imported products. Many companies do not focus on hydraulic hose and pipeline accessories, product types are not complete, some even just the production of hose, no compression process, do not provide transfer first class pipeline accessories.China's hose production enterprises have developed to more than 1,000, more than 300 enterprises above the scale, the industry belongs to the full competition industry, the degree of marketization is high, the competition between the companies is fierce. In so many hose enterprises, most of the products produced belong to low-end products, mainly rely on price competition, in the high-end field, a small number of domestic hose head enterprises directly compete with foreign manufacturers.The importance and processing requirements of hydraulic pipe joints1, the importance of hydraulic pipe jointsThere are many types of hydraulic pipes, and the corresponding types of pipe joints are also many. The joint is a detachable connection between the oil pipe and the oil pipe, the oil pipe and the hydraulic component, which needs to meet the requirements of convenient assembly and disassembly, solid connection, reliable sealing, small shape size, large oil flow capacity, small pressure loss, and good processing technology.The quality of the pipe joint plays a vital role in the safe operation of the hydraulic system. The development of hydraulic system conforms to the needs of environmental protection, and all users not only have higher and higher requirements for the safety and noise-free hydraulic system, but also want to have a completely leak-free hydraulic system. For the leakage problem of the hydraulic system, there is a clear data that 70% of the equipment has a leakage problem, and 70% of the leakage problem occurs in the pipeline connection. Due to the failure of the joint, serious safety accidents may occur, such as the hose being thrown out of control and wounding people or the hot, cold, poisonous media spewing out and wounding people.2, the processing requirements of hydraulic pipe jointsThe production of hydraulic pipe joint is mainly completed by CNC lathe processing. The main processing requirements are:High-speed processing: The wide application of hydraulic hoses represents the synchronous growth of the demand for pipe joints, so the production of pipe joints requires rapid delivery in large quantities, the higher the production efficiency, the higher the economic benefits generated per unit time.High precision processing: Due to the high standard requirements of the pipe joint in sealing, preventing withdrawal, and fluid passing through the liquid resistance, the workpiece size should be stable during processing, the processing accuracy should be controlled within 0.02mm, and the knife pattern is uniform, and the arc has no cutter mark.Safe processing: The operation of CNC machine tools is carried out manually, and the safety of production personnel is the first priority at the processing site.
