【摘要】：随着能源短缺问题的日益严重,人们将越来越多的目光集中在节能减排上。而液压行业作为我们国家的重要行业,对国民经济的发展起着重要作用。但是液压传动油液污染比较严重,系统效率很低,这不适应当前环保和节能减排的要求。而本文将对步进梁液压系统的节能设计作出深入研究。研究主要内容如下: 1.从液压系统的组成和能量转换上进行分析,得出液压系统效率低的原因是由于能量的损失造成的。能量损失主要包括能量转换元件的能力转换损失、结构布局决定的传输损失和动力源与负载特性不匹配的匹配损失。 2.根据能量损失的原因通过不同的节能途径来改善提高液压系统的效率,如提高系统的能量转换效率、提高原动机功率的利用率、提高系统的传输效率和液压源的合理利用,以及使用液压节能回路和其他节能途径。 3.以某钢厂步进梁加热炉液压系统为实例,通过不同的节能途径对该液压系统进行节能改造和设计。在系统中使用负载敏感泵液压源来对负载的流量和压力进行匹配,最大限度的实现节能效果。利用液压仿真软件AMESIM对负载敏感泵进行模型仿真,改变模型参数对其进行结构优化。对步进梁液压系统进行AMESIM仿真,得出该系统的压力,流量随着负载的压力流量相匹配,在最大程度上实现节能。本文通过对液压系统节能途径作出了分析和总结,在步进梁液压系统中运用节能途径进行节能改造和设计,运用AMESIM仿真软件对步进梁液压系统的节能性进行了验证,为液压节能系统的设计提供了依据,特别是对与特大型重载步进梁加热炉液压系统在节能方面具有重要意义。
[Abstract]:With the increasingly serious energy shortage, people will focus more and more attention on energy saving and emission reduction. The hydraulic industry, as an important industry in our country, plays an important role in the development of the national economy. But the hydraulic transmission oil fluid pollution is serious and the system efficiency is very low, which does not meet the requirements of the current environmental protection and energy conservation and emission reduction. In this paper, the energy saving design of walking beam hydraulic system will be deeply studied. The main contents are as follows:
1. from the composition and energy conversion of the hydraulic system, it is concluded that the reason for the low efficiency of the hydraulic system is due to the loss of energy. The energy loss mainly includes the capacity conversion loss of the energy conversion element, the transmission loss determined by the structure layout and the matching loss of the mismatch between the power source and the load characteristic.
2. according to the causes of energy loss, the efficiency of the hydraulic system is improved by different ways of energy saving, such as improving the efficiency of the energy conversion of the system, improving the utilization of the power of the original motive, improving the transmission efficiency of the system and the rational use of the hydraulic source, and using the hydraulic energy saving circuit and other energy saving ways.
3. taking the hydraulic system of a steel mill step beam heating furnace as an example, the hydraulic system is retrofit and designed by different ways of energy saving. In the system, the load sensitive pump hydraulic source is used to match the load flow and pressure, and the energy saving effect is realized to the maximum limit. The hydraulic simulation software AMESIM is used to pump the load sensitive pump into the system. The structure optimization of the model is changed by the model simulation. The AMESIM simulation of the hydraulic system of the step beam is carried out to get the pressure of the system. The flow rate is matched with the pressure flow of the load, and the energy saving is realized to the maximum degree.
By analyzing and summarizing the energy saving ways of the hydraulic system, the energy saving transformation and design are used in the step beam hydraulic system, and the energy saving of the step beam hydraulic system is verified by using the AMESIM simulation software, which provides the basis for the design of the hydraulic energy saving system, especially to the oversize and heavy load step beam. The heating furnace hydraulic system is of great significance in energy saving.
