Part Two: Exploration of Energy Consumption Issues of Existing Underground Loader
1、 Introduction
With the rapid development of the social economy, energy consumption is gradually increasing, and environmental problems are becoming increasingly serious. Among them, energy consumption of industrial equipment is one of the important reasons for environmental pollution and resource waste. Underground loader, as a commonly used engineering machinery equipment, is widely used in mining, construction and other fields, and its energy consumption has attracted much attention.
This article will delve into the energy consumption issues of existing underground loaders and propose corresponding development plans for electric underground loaders in conjunction with energy-saving and emission reduction goals.
2、 Energy consumption analysis of existing underground loaders
1. Energy types and usage
At present, the mainstream underground loaders in the market mainly use diesel engines as the power source. Due to the high thermal efficiency and good power performance of diesel engines, they are widely used in various types of underground loaders. However, diesel engines generate a large amount of exhaust emissions during operation, including harmful substances such as carbon dioxide (CO2), nitrogen oxides (NOx), and particulate matter (PM), which have a significant impact on the environment.
In addition, with the increasing depletion of oil resources and price fluctuations, diesel costs have become a major expense in underground loader operations. According to statistics, the fuel cost of underground loaders accounts for about 40% of the total operating costs. For mining enterprises, reducing energy consumption has become one of the key factors in improving economic efficiency and achieving sustainable development.
2. Energy consumption characteristics and cause analysis
The energy consumption of underground loaders mainly includes three parts: mechanical energy loss, thermal energy loss, and energy loss caused by vehicle accessory loads.
Mechanical energy loss mainly refers to the energy loss caused by the movement resistance of the bucket during excavation, loading, transportation, and unloading processes. This part of energy loss is closely related to factors such as the design parameters and operating conditions of the working device.
Thermal energy loss is caused by the underutilization of heat generated during the combustion process of internal combustion engines. The thermal efficiency of diesel engines is usually between 35% and 45%, with most of the heat being emitted into the atmosphere in the form of exhaust gas, while the remaining energy is used to drive the vehicle.
The energy loss caused by vehicle accessory loads includes the power supply required by auxiliary equipment such as lighting, air conditioning, and hydraulic systems during operation. Although these devices are not directly involved in the shoveling work, they also consume some of the power output from the engine.
From the above analysis, it can be seen that the existing underground loaders have problems such as low energy utilization, high pollution emissions, and high operating costs. To address these issues, this article proposes a development plan for an electric underground loader aimed at achieving energy-saving and emission reduction goals.
