Precautions for Handling Precautions 1. Remove the cylinder (1) cylinder before demolition, have to make the hydraulic circuit relief, otherwise, when the tubing joints loosen the cylinder is connected, the loop will be pressure on the high pressure oil quickly ejected, so you must first remove the hydraulic circuit pressure hollow cylinder, then cut off the power supply or power source, until the hydraulic unit stopped before they can be demolished. (2) at the time of the demolition must be careful not to damage the piston rod, screw, cylinder inner wall, etc., in order not to bend the rod and other elongated member or deformation, can use skids. (3) Remove the fuel tank to be carried out in accordance with the order, remember not to reverse the order, due to the many types of cylinders, are not the same size, so the corresponding order of removal is also different, the basic sequence is to let go of the oil in the cylinder, then remove the cylinder head, finally, and then disassemble the piston rod. When removing the piston or rod, piston or rod is difficult to extract if large tonnage cylinders, can not be forced out of use brute force, this will damage or even damaged parts, should identify the reasons for, and then demolished. The reason appears dirty hydraulic hydraulic oil mixed with water, rust or both of a hydraulic oil appears dirty or rusty simultaneously mixed with water ① Check the water system is at the same time there is oil, if the fuel tank manufacturers, indicating that V-ring may push agencies damage. Time to replace the V-ring. ② Check the fuel tank filler neck is not covered, and other contaminants into the water. If it is then filtered to remove water and hydraulic oil and fuel tank filler cover. ③ Check the hydraulic system components ministries, whether because they are caused by oil pollution damage. Second, the master cylinder piston rod vibration due to work ① check whether the oil level is too low, the pump suction air caused by hydraulic cylinder piston crawl. At this point the need to refuel the specified oil level. ② Check the main pump inlet system for leaks. ③ Check whether the push bodies V-ring compression tight three, high oil temperature ① Check the main relief valve is faulty and often overflow. ② Check the auxiliary electro-hydraulic valves, unloading valves are especially fault. Because they make the dispensing valve pumps unloading time is shortened, often in high load operation is faulty. Then the need to exclude its two valve failure. ③ replaced as hydraulic oil, need to check the oil viscosity is too low, so that the internal pump leakage consumption too. Fourth, the two movements are not synchronized push piston hydraulic cylinder piston push two movements are not synchronized in the suction stroke of the piston speed, the first to reach the end of the stroke cylinders, cylinders hit phenomenon sometimes occurs, you can hear the cylinder piston and cylinder cover crash, this is generally due to the closure of memory in the air and cause the oil.
