单斗液压挖掘机发动机微机节能控制系统

为了有效地控制单斗液压挖掘机在工作过程中的能量损失，减少液压系统的发热，改善工作性能，特设计了一种单斗液压挖掘机发动机微机控制系统该控制系统采用负荷传感，由微机判断挖掘机的工作状态，并据此控制发动机而达到节能的目的该系统具有中位自动怠速、降低液压系统的节流损失和溢流损失等功能使用该控制系统并不需要改变挖掘机的液压系统及其它结构本文在简要介绍了该控制系统工作原理的基础上，详细地分析了该系统的节能原理及效果

A Computer Controlled Energy-Saving System for Hydraulic Excavator

A computer controlled energy-saving system is introduced which is designed to reduce energy loss and over heating in hydraulic system. According to the load, the control system can automatically regulate the engine to assure optimum utilization of its output and to reduce pump output when joysticks are in the neutral position or before the permitted operating pressure reached. After the explanation of operating mechanism of the control system, the energy-saving principle and effectiveness is analyzed in this paper. It is not necessary to change any other parts of the excavator using this control system.
