<p>Disclosed in the present invention are a pumping device, a hydraulic distribution system and a heating method thereof. The hydraulic distribution system comprises a hydraulic pump (1), a direction valve (7), a check valve (2), an accumulator (5) and a pressure control assembly. The hydraulic distribution system comprises a working mode and a heating mode, wherein, in the heating mode, the hydraulic pump (1) is able to drive the hydraulic oil to overflow through the pressure control assembly, so that the hydraulic energy is converted into heat energy, and then the temperature of the hydraulic oil can be raised by the heat energy. Thus, the hydraulic oil can be heated evenly without the need for an additional heater.</p> |
