The invention discloses a method for forecasting the wear-resisting property of a rotor and a lining plate of an elastic cam rotor pump. The method comprises the following steps: accessing a to-be-detected elastic cam rotor pump into a wear-resisting property test platform; acquiring the data of the mixed concentration injected solid and liquid, the rotation speed of a motor and the switching-on degree of a gas valve according to a working condition database; adjusting the wear-resisting property test platform, thereby acquiring the damage time of the rotor and the lining plate of the elastic cam rotor pump under different working conditions; and fitting a wear-resisting property curve formula according to the wear-resisting property data. According to the method, the wear-resisting property test platform is utilized to acquire the damage time of the to-be-detected elastic cam rotor pump under different working conditions in the manner of experiment; the interpolation fitting is performed on the data of the working conditions and the damage time so as to acquire the relation of the damage time and the working conditions; a curve corresponding to the relation is regarded as the wear-resisting property curve, so that the relation can be utilized to forecast the wear-resisting property of the rotor and the lining plate of the elastic cam rotor pump.
