Many users use the hydraulic valve on the useless any larger problems, but after the maintenance and cleaning is nothing but the clue, and now to analyze the hydraulic valve cleaning technology. Pay attention to the following problems during cleaning: (1) For the long deposition time in the hydraulic valve, firmly paste the dirt, do not scratch the mating surface when cleaning. (2) pay attention to safety when heating. Some inorganic cleaning fluid is toxic, heating can cause toxic poisoning, should be used with caution; organic cleaning fluid flammable, pay attention to fire. (3 When choosing the cleaning liquid, pay attention to its corrosion, to avoid corrosion on the valve body (4) After cleaning parts should be kept to avoid corrosion or re-contamination (5) assembled hydraulic valve to pass the test before passing into use Common cleaning processes include: (1) Disassembly Although hydraulic components are mostly bolted to each other, hydraulic valves are designed for non-disassembly and if disassembled without special equipment or know-how, disassembly is most likely to result in hydraulic valves Damage, so before disassembly to master the hydraulic valve structure and the connection between the parts, when disassembled record the relationship between the various parts. (2) check and check the body, valve and other parts of the dirt deposition, without damage Work surface under the premise of using cotton yarn, brush, non-metallic scraper to remove concentrated dirt. (3) Rough wash. The valve body, valve and other parts on the cleaning box tray, heated soaking, the compressed air access Cleaning tank bottom, through the stirring effect of bubbles, cleaning the residual dirt, the conditions can be ultrasonic cleaning. (4) Fine cleaning. High-pressure cleaning with cleaning fluid Finally, the use of hot air drying. Conditional companies can use the existing cleaning agents, some occasions can also use organic cleaning agents such as diesel, gasoline. (5) assembly. According to hydraulic valve assembly diagram or record the demolition of the assembly relationship assembly, Be careful when assembling, do not bump parts. The original sealing material is easy to damage in the demolition, it should be replaced when assembled.Due to the different enterprise maintenance technology and equipment at different levels, the quality of maintenance there will be a big difference.For the maintenance of equipment and The lack of technology companies, even after maintenance to make the hydraulic system back to its original state, should be strengthened surveillance and actively buy spare parts to deal with unexpected failures.
