Design and Simulation of Hydraulic Driven Energy Saving Overpass
摘要
Abstract
Traditional motor-driven elevators consume electrical energy both during upward and downward movements of passengers,and there is a waste of gravitational potential energy when passengers descend.In response to the problem of wasted gravitational potential energy of downward passengers,an energy-saving hydraulic driven elevator device suitable for overpasses is proposed by adopting a hydraulic transmission system combining hydraulic pumps and hydraulic motors.One side of the configuration is changed to a car,and two cars simultaneously meet the needs of passengers for upward and downward movement.A new hydraulic drive system has been designed,which uses a hydraulic pump to convert the gravitational potential energy of passengers in the downward elevator car into hydraulic energy storage.When there is a passenger's upward demand,the pressure energy stored in the accumulator is converted into mechanical energy.A mathematical model of the hydraulic drive system has been established,and AMESim simulation shows that the energy-saving pedestrian overpass straight ladder device runs smoothly.When the accumulator is fully charged,it can provide about 3 times for a 2 000 kg fully loaded passenger to ascend.When full loaded passenger descends,the recovered gravitational potential energy accounts for about 1/6 of the total capacity of the accumulator,effectively achieving energy-saving needs and having certain application prospects.关键词
