Double acting self-locking jacks are used in large ship engineering

SL-HM series hydraulic nut is our high and new product,The body is chromium-molybdenum steel, replacing foreign first-tier brand products. The surface is knurled and blackened, light weight and easy to install and disassemble using specific wrenches, the working principle of the hydraulic nut of the slitting machine is to input the hydraulic oil into the nut through the high pressure oil pump, and push the piston to produce thrust and tension, so as to fasten the rotating tools (such as gaskets, knives, etc.). Specifically, use the ‘T-handle’ to rotate the ‘pressurised screw’ and press in the ‘pressurised piston’ to increase the pressure of the sealing fluid, which in turn squeezes out the ‘ring piston’. ‘In this case, the sealing fluid pressure increases and squeezes out the ‘ring piston’ to tighten the rotating tool (washer, cutter, etc.). At the same time, it is possible to check whether the scale of the ‘Thrust Indicator’ corresponds to the determined thrust value. In addition, the slitting machine hydraulic nut is characterised by a high axial locking force, which securely locks the blade on the slitting machine and prevents deformation under axial pressure.
