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 issues. 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 soak, the compressed air access The bottom of the cleaning tank, through the stirring effect of bubbles, to clean the residual dirt, the conditions can be ultrasonic cleaning. (4) Fine wash. High-pressure cleaning with cleaning fluid, and finally with Wind drying.Conditional enterprises can use the existing cleaning agent, some occasions can also use organic cleaning agents such as diesel, gasoline. (5) assembly.According to the assembly diagram of the hydraulic valve or the parts recorded in the assembly relationship assembly, assembly Be careful not to bump parts. The original sealing material in the demolition of easy to damage, should be replaced when assembled due to different enterprises of the maintenance techniques and equipment at different levels, there will be a great difference in the quality of maintenance.For the maintenance of equipment and lack of technology Of the enterprises, even if the hydraulic system has been repaired to restore the original status, monitoring should be strengthened and spare parts should be actively purchased to deal with unexpected failures.
