Hydraulic shear oil cylinder is a kind of common oil cylinder equipment with high utilization rate. After using the oil cylinder of the plate shearer for a period of time, the internal part of the oil cylinder of the plate shearer is easy to be scratched. What is the cause?

1、 When the piston is sliding, if the surface pressure is too large, it will lead to sintering. The main reason is that the weight of the piston itself inclines, or the piston is not strong and the load appears in the transverse direction. As a result, when the hydraulic shear piston is sliding, the pressure on the entire surface has increased significantly, leading to serious sintering.

2、 Before the installation of the hydraulic shear cylinder, the piston has appeared serious scars, basically because the surface of the piston was scratched when it was sliding, but it was not solved and treated in time, but it was directly installed for work, so these scars will directly scratch the interior of the shear cylinder, so when we install it, It is necessary to conduct a thorough inspection.
