After the wear of the hydraulic pump plunger, traditional grinding repair can lead to a decrease in plunger diameter, affecting the pump's displacement accuracy. After repair, the pump's volumetric efficiency decreases by 10% -15%. Daokedao adopts laser cladding+precision grinding technology to fuse a 0.1mm thick alloy coating on the surface of the plunger. After repair, the plunger diameter tolerance is ± 0.001mm and the surface roughness is Ra0.02 μ m. After repairing 1000 plungers at a hydraulic parts factory in South Korea, the volumetric efficiency of the hydraulic pump remained above 95%, consistent with a new pump. The cost of repairing a single plunger was only 20% of that of a new part, saving an annual cost of 600000 yuan. The repaired plunger passed a 1000 hour high-pressure test without any leaks, and the customer return rate decreased from 8% to 0.5%.
