Hydraulic energy storage loop and engineering machinery
The invention relates to the technical field of hydraulic energy storage and energy saving of engineering machinery, in particular to a hydraulic energy storage loop and engineering machinery. The hydraulic energy storage loop comprises an energy accumulator assembly, a reversing valve assembly, a pressure sensor assembly and a controller; an inlet in the energy accumulator assembly is used for communicating with a hydraulic actuating element used for energy saving through the reversing valve assembly, and an outlet in the energy accumulator assembly is used for communicating with a hydraulicpipeline used for actuating; the pressure sensor assembly is arranged on the energy accumulator assembly and measures the real-time pressure of the energy accumulator assembly; and the controller is electrically connected with the pressure sensor assembly, and the controller controls the reversing valve assembly to act according to the real-time pressure, so that the energy accumulator assembly isconnected with or disconnected from the hydraulic actuating element used for energy saving. The engineering machinery comprises the hydraulic energy storage loop. According to the hydraulic energy storage loop and the engineering machinery, hydraulic energy converted from recovered mechanical energy by the hydraulic actuating element used for energy saving is stored and accumulated, and the hydraulic energy is continuously supplemented to the hydraulic pipeline used for actuating, so that the working efficiency of the engineering machinery is improved, and the oil consumption is reduced.
