FIELD: electrical engineering.SUBSTANCE: energy-recovery generation system for electric loader comprises hoisting cylinder (9). Output pipeline of hoisting cylinder (9) is provided with pressure sensor unit (1) and directional valve (2). Directional valve (2) is under control of pressure sensor unit (1). First outlet of directional valve (2) is connected to tank (5) through a way of multi-way valve (4) with an operating handle. Pressure oil, flowing out from a second outlet of directional valve (2), passes through pump (7) having an oil suction port capable of bearing pressure or a motor, and then passes through multi-way valve (4), to finally flow back to tank (5). In engine mode, pump (7) having an oil suction port capable of bearing pressure, drives electric motor (16) to output electric energy. Electric energy output end of electric motor (16) is connected to energy storage device (20) through converter (21).EFFECT: invention ensures energy saving.10 cl, 6 dwg |
