Such as "bucket" action, "nod" phenomenon, pipe joints are often broken, etc., but whatever the reason, all hydraulic transmission problems can be summarized as: pressure, flow, direction of the three major issues. The three major problems are caused by leakage, blockage, tubing connection and pressure adjustment. Therefore, we must pay attention to the maintenance of hydraulic system failure: hydraulic components must pay attention to whether to clean, until the oil treatment is smooth before you can assemble. Do not use unclean hydraulic oil, do not use inferior seal. Be sure to assemble components correctly, such as "Y" ring, the opening can not be reversed, the pipe can not be connected wrong. The adjustment of the safety valve is not disturbed before it is clear, so as not to cause the hydraulic component to be washed up, the work is slow, weak or without action. Once the system is out of order, do not blindly, in accordance with the "general" sequence analysis from easy to difficult, from outside to inside, the first focus on and solve the problem, first check the external leakage, check the amount of oil oil, check the congestion, caused by internal fault components for system failure, you must understand the principle again to check, to avoid unnecessary waste.
