20120134849CHARACTER PARAMETERS OBTAINING METHOD FOR DISPLACEMENT CONTROL MECHANISM OF HYDRAULIC PUMP AND DETECTING DEVICE FOR CARRYING OUT THE METHOD - A character parameters obtaining method for a displacement control mechanism of a hydraulic pump and a detecting device for carrying out the method are disclosed. The method involves constructing a hydraulic system; outputting hydraulic energy by the hydraulic pump driven by a primary motor; detecting pressure of a displacement control mechanism; obtaining middle parameters by obtaining the time required for preset change of the pressure at the output end of the displacement control mechanism; obtaining character parameters of the displacement control mechanism according to the middle parameters. The method can obtain the character parameters of the displacement control mechanism by the pressure detection, so that the performance of the displacement control mechanism can be judged according to the obtained character parameters. The method avoids the need of obtaining the output flow of the hydraulic pump so as to eliminate the problem caused by using a flow meter or using an obliquity sensor to obtain the character parameters.05-31-2012
