Hydraulic shears new generation of modular design feature coverage, greater reliability, can meet the needs of different users. Further, in the hydraulic system, hydraulic components are moved relative to the surface. <br>The: <br>hydraulic cylinder surface and an outer surface of the piston. Because there must be relative movement, so it has a certain gap therebetween. If one side of the gap caused by the leakage of high pressure oil, the other side of low pressure oil, high pressure oil will flow to the low pressure region through the gap.
