In the scrap industry and the field of scrapped vehicles with excavators with hydraulic shear more and more popular, if your excavator is using hydraulic shear should pay attention to the following maintenance rules:
No.1:Hydraulic shear cylinder maintenance: hydraulic shear long-term use, hydraulic oil will become dirty and high temperature, cylinder seals will appear aging phenomenon, it is recommended to replace the seal of the cylinder once a year.
No.2:Hydraulic shear blade replacement: Hydraulic shear blade is a wearing part, but blade manufacturers can generally design four sides can be changed to use, when all four sides appear to crash, it is recommended to replace the hydraulic shear blade in time, if not timely replacement of the blade, it is not shear force generated when cutting scrap steel, but radial extrusion pressure to break the scrap steel, it is not shear force cut. Huge radial extrusion pressure will squeeze the tool body deformation or fracture!
No.3:Hydraulic shear blade clearance: Hydraulic shear in use for a period of time will produce a larger blade gap phenomenon, there are a variety of reasons for the larger gap is generally after the release of processing stress or link sleeve gap wear caused, then you have to stop the wrench used by the hydraulic shear manufacturers to adjust the blade with the gap,to adjust the gap each method is not the same, you can call the manufacturer how to adjust the gap, Only when the gap is adjusted well, a good cutting effect will be produced after that .
