叉车负载重力势能回收

摘要

叉车在工作过程中，举升装置会产生重力势能，利用蓄能器回收负载的重力势能，将其转化为液压能储存起来，在下一个工作周期重新利用，有效优化叉车的工作效率。文中主要分析蓄能器初始充气压力、系统能量回收效率、蓄能器体积三者的关系，以找到在能量回收系统中三者的最优组合。%When the forklift is in operation,the lifting device will produce gravity potential energy,recycles the load-ed gravitational potential energy with the energy accumulator and saves it by converting it into the hydraulic state for reuse in the next working cycle,which can effectively optimize working efficiency of the forklift.The paper mainly analyzes the rela-tionship between the initial inflation pressure of energy accumulator,system energy recycling efficiency,energy accumulator volume to find out the optimum combination in the energy recycling system.
