(1) try to make the cylinder rod to withstand the maximum load in the tensile state, or having a good stability under pressure state (2) to consider issues cylinder stroke exhaust brake problems at the end of the hydraulic cylinder . If there is no buffer cylinder and exhaust system, the system need to have appropriate measures, Yangling tanks, but not all cylinders must consider these issues. (3) Installation for fixed correctly determine the hydraulic cylinder. As the piston rod is not subjected to bending with a threaded connection, use only the mouth connection. Hydraulic cylinders can not be positioned at both ends with the key or pin. Positioned at one end only, large tonnage cylinders, as is not to hinder it expands when heated. The impact load compression piston rod. Positioning member shall be provided in the piston rod end, such as the stretch is set at the head end. Repair process: 1, with oxygen - acetylene flame grilled scratched site (control temperature, avoid surface annealing), the perennial infiltration metal surface oil baked, grilled to no sparks. 2, the scratch area with angle grinder surface treatment, non-standard cylinders, grinding depth of 1 mm or more, a single-acting cylinder and polished grooves along the rail, preferably dovetail. Drilling deeper scratches ends, change the forces. 3, with cotton wool dipped in acetone or ethanol to clean the surface. Double-acting cylinders, Yangling cylinders, hydraulic force provided by the Texas Lu Lu of the hydraulic machinery plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) strong, credible, in Dezhou hydraulic machinery and components industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Lu Hydraulic and you hand into the brilliant, for a better future!
