采用液压绞车和蓄能器的液压挖掘机动臂势能回收再利用节能装置
Energy-saving Device for Potential Energy Recovery and Reuse of Hydraulic Excavator Boom with Hydraulic Winch and Accumulator
摘要
Abstract
To reduce the overall energy consumption of hydraulic excavators and improve the energy utilization efficiency of the hydraulic system,this study proposes an energy recovery and reuse system for the potential energy of the excavator's boom,utilizing a hydraulic winch and an accumulator.The system recovers gravitational potential energy during boom descent and reuses it to assist in boom lifting,thereby reducing the working pressure of the hydraulic system and decreasing fuel consumption.First,the working principle of the system is elaborated in detail,and a mathematical model of the energy-saving device is established.Next,the system is modeled and simulated using AMESim software.The simulation results demonstrate that the system effectively recovers the gravitational potential energy of the descending boom and assists in boom lifting,achieving an energy-saving efficiency of approximately 55.6%.Finally,an experimental bench is constructed to validate the feasibility and effectiveness of the proposed energy-saving device.关键词
