HYDRAULIC SYSTEM WITH REDUCED LOADING/UNLOADING IMPACT AND METHOD FOR REDUCING IMPACT OCCURRED ON LOADING/UNLOADING

摘要

The present invention relates to a hydraulic system in which a loading / unloading impact is reduced and a loading / unloading impact reducing method in a hydraulic system. The hydraulic system according to the present invention comprises a tank containing a working fluid, a hydraulic pump for sucking and pressurizing the working fluid in the tank through an inlet pipe, a hydraulic pump connected to the hydraulic pump through an outlet pipe, A hydraulic motor driven by the working fluid, a servo motor for driving the hydraulic pump, a pressure sensor connected to one side of the outlet pipe of the hydraulic pump to measure the pressure of the working fluid, The control unit is configured to control the operating conditions of the hydraulic pump after the loading / unloading time based on the pressure change rate just before the loading / unloading time.
