How to repair the metal baler after failure

The application of metal baler is very extensive, it is precisely because of its overload work, so under the long-term high-intensity work of the equipment, the occurrence of failure is inevitable. Many times, our equipment manuals will show our numerical range. At this time, please make sure that this value is normally in the laboratory environment. Your working environment is not the same as the laboratory environment, so the actual If you do not strictly follow the operation procedures of the metal baler during the operation, the chance of equipment failure will be greater.

Before disassembling the hydraulic cylinder of the metal baler, the pressure should be relieved by the gear oil circuit. Otherwise, when the connector connected to the hydraulic cylinder is unscrewed, the high-pressure oil in the return fuel pipe will be ejected. When the control circuit of the hydraulic machine is relieved of pressure, it is necessary to unscrew the handle of the governor valve or the pressure-changing screw to make the working pressure oil throw up, and then disconnect the switching power supply or energy source, so that the hydraulic control valve stops running.

When disassembling, the external thread on the top of the piston, the external thread on the oil hole, the surface of the piston and the inner cavity of the cylinder liner should be avoided. In order to avoid bending or deformation of fine parts such as pistons, the supporting points of the pads should be balanced when placed.

The disassembly and assembly of the hydraulic cylinder of the metal baler should be carried out in a clean and clean natural environment to avoid environmental pollution by the surrounding dust, residue and other wastes. The disassembled parts shall be subjected to anti-fouling maintenance.

Before disassembling the hydraulic cylinder of the metal baler, the hydraulic oil in the two chambers of the hydraulic cylinder should be drained.

After disassembling and assembling, the metal baler should be carefully inspected to determine what parts can be used again and what parts should be repaired.

The disassembly and assembly of metal baler should be carried out in order. Because various hydraulic cylinders have different methods, the disassembly order is also slightly different. Generally, the cylinder head should be disassembled first, and then the piston rod and piston should be disassembled. When disassembling the cylinder head of the hydraulic cylinder, tools should be used for the snap keys or ductile flat washers of the internal snap connection. Flat shovel is strictly prohibited: for flanged bearing end caps, it must be shot with screws, and no hammering Hard pry. When the piston rod and piston cannot be drawn out, it is not necessary to force it out, and the disassembly and assembly must be carried out for the sake of reason, and the forceful operation will cause scratches.
