Modern Techniques for Remanufacturing Hydraulic Equipment in the Context of Circular Economy and Energy Efficiency

The article presents several current methods of remanufacturing hydraulic components, a trend that is encouraged, on the one hand, by concerns about reducing material consumption in context circular economy - some these materials being expensive or short supply. On other modern can lead to decrease energy devices concerned, due obtaining shapes are difficult achieve classical procedures. Among processes considered there additive manufacturing, metal coating, reverse engineering, etc. An important step process testing which certifies achievement performances at least equivalent those original products. To this end, test bench solution with help tests be carried out such as pumps and (linear rotary) motors, directional control valves types valves.
