The invention discloses a hydraulic pump testbed system with an energy recovery function and an energy recovery method. The system comprises a power grid, a controller, an electric motor, a hydraulic pump testing system (an open system or a closed system), a power generator, an energy storage unit and a control platform. The testbed not only can be used for conducting a hydraulic pump performance test but also can achieve power recovery, and the initial power source of the testbed is obtained after the power grid drives the electric motor electrically and then the electric motor drives a hydraulic pump. In the hydraulic pump testing system, the hydraulic motor serves as the load, the power generator is connected to the back side of the hydraulic motor to achieve energy recovery, the energy of the system is converted into electric energy to be recovered or stored, recovered energy is fed back to the power grid or electric motor through the controller, so that energy saving is achieved, and the power grid plays a role in energy supplement after the system is stabilized; all the elements are monitored by the main control platform, so that the system runs as required. By the adoption of the hydraulic pump testbed system, energy recovery and circular flow can be achieved, the amount of electricity obtained from the power grid is reduced, power is saved, and heat productivity is low. The hydraulic pump testbed system has great significance in research of engineering machinery hydraulic pump testbed power recover methods and energy-saving devices.
Description
【Technical field】 [0001] The invention belongs to the field of hydraulic component performance test benches, relates to the energy recovery technology in the hydraulic component test experiment process, and adopts the energy recycling technology to realize the effects of power recovery and energy saving. 【Background technique】 [0002] At present, the hydraulic test bench generally adopts an open structure, and the traditional hydraulic pump test is carried out in the way of power consumption, that is, the test is carried out by overflow or / and throttling loading. During the test, the pressure oil produced by the hydraulic pump overflows directly through the relief valve, and all the energy is converted into heat energy, resulting in a waste of energy. In addition, the heating of the test system will also cause the oil temperature to rise, and the system has to add a cooling device of a corresponding scale to reduce the oil temperature, which increases the cost of the test e...
