An automatic-pressure-matching energy utilization system, comprising a synchronous motor (1), a control valve (2), a working pump (3), an energy accumulator (4), a pressure actuator (5), and corresponding oil path connections. A master outlet (OUT) of the synchronous motor is connected to a load holding chamber of the pressure actuator; a first inlet (IN1) of the synchronous motor is connected to an oil port end of the energy accumulator by means of a first switch valve (K1) of the control valve; a second inlet (IN2) of the synchronous motor is connected to an output port of the working pump by means of a second switch valve (K2) of the control valve. The system can automatically match the output pressure between the working pump and the energy accumulator in accordance with the size of the external load, thereby fully utilizing pressure energy recovered in the energy accumulator.
