挖掘机作为典型灵活多功能的工程机械产品,节能性一直是其追求目标。随着液压挖掘机不断深入应用于市场,对其节能效果评价显得尤为重要。但由于液压挖掘机作业工况复杂,各企业在选择测试和评价挖掘机节能效果的标准不统一,因此节能水平严格说来不具可比性。本文针对新技术条件下的液压挖掘机,建立统一有效的挖掘机燃油消耗试验方法,对液压挖掘机在各种典型工况作业条件下的节能效果进行科学评价,具有十分重要意义。
As a typical flexible and versatile construction machinery product, the excavator has always been the pursuit of energy conservation. With the continuous application of hydraulic excavators in the market, it is particularly important to evaluate their energy-saving effects. However, due to the complex working conditions of hydraulic excavators, the standards for selecting and testing the energy efficiency of excavators are not uniform among companies. Therefore, the level of energy conservation is not strictly comparable. This article aims at a new hydraulic excavator under the conditions of the new technology, establish a unified effective test method for fuel consumption of the excavator, and evaluates the energy saving effect of the hydraulic excavator under various typical working conditions, which is of great significance.
