Ingenious repair method for piston rod strain
Aug 28, 2018

There are many construction machinery in the process of actual operation, the piston rod inside the hydraulic cylinder often has a scratched surface. Scratches on the piston rod of the hydraulic cylinder should be repaired in time, otherwise the seal will be invalid, resulting in oil leakage of the hydraulic cylinder. For the treatment of not serious scratches, the whine is usually removed by the oil stone grinding method.

 

If the scratches are serious, the piston rod is usually removed and then brushed, but this repair method takes a long time and costs more. In fact, when we found scratches or pits on the surface and high-voltage electric shock, the repairing machine repaired the hydraulic cylinder without disintegrating in the field.

 

The specific repair process is as follows: 1. Firstly, the part of the piston rod is cleaned. It is recommended to use acetone to scrub the scratched surface and wash off the surface oil. 2. Welding method, the welding material can be 0.02 mm stainless steel or steel tape. Instead of a roll, the length can be determined based on the length of the scratch. If the scratch is large, such as one time can not be flattened, another piece of welding can be placed and flattened, then the weld is smoothed with oil stone, and finally the weld is polished with 0 water sandpaper to make it smooth and smooth and smooth transition.http://www.xhychromerod.com/
