Message: | Ryan is from a hydraulic equipment company in Brazil. In the first half of this year, they had a hydraulic logistics equipment complained by users that the control was abnormal. The after-sales engineer found that the instantaneous peak pressure of the hydraulic cartridge directional control valve was too high during the reversing process, which affected the function of the hydraulic cartridge directional control valve and led to unstable equipment control, so the hydraulic cartridge directional control valve had to be replaced. The hydraulic cartridge valve manufacturer thought that the hydraulic cartridge directional control valve was produced according to the drawing, and its function and accuracy were up to standard. The valve was tested separately and no abnormality was found. The after-sales team was helpless, and the boss asked Ryan to re purchase the hydraulic cartridge directional control valve to solve the after-sales problem first. Ryan has no idea and no direction. He spent a week without any results. |
