【摘要】：由于世界能源危机的爆发,节能技术被各个行业所重视,而液压系统存在多次能量转换,其能耗较电气传动和机械传动大,而且液压油造成潜在环境污染和油的损耗,加上液压系统的噪声也高,在能源紧张的今天其应用领域正逐渐被其他传动技术所压缩,液压领域在未来发展的方向之一就是如何降低液压系统能耗,完善液压系统节能技术。因此,在保证性能要求与可靠性的同时还能实现高效节能,这对液压控制系统来说具有非常重要的意义。现有的大部分节能控制技术只适用于泵控系统,而在阀控系统中的节能技术有待突破,故研究一种既保证高响应性能又能消除重复节流损失实现节能的控制阀能够为阀控系统中的节能技术开辟一条新途径。本文根据集成式高性能节能控制阀的基础理论-阀口独立控制原理,研究集成式高性能节能控制阀的节能控制。在保证高响应性能的前提下,依据工况要求进行单边节流控制,消除常规控制阀因节流边机械固联的重复节流损失,和通过应用差动回路使流量再生来实现节能的目的。本文研究了利用集成阀在多种工况下的节能原理与控制策略、基于多个基本单元实现高响应节能控制的协同控制方法、以及集成阀的动、静态特性研究。理论分析和实验结果表明,利用集成阀可大大提高液压系统的效率。本项研究为提高阀控系统的效率开辟新的途径,并为该种控制阀的工业化应用奠定理论和技术基础。
[Abstract]:Because of the outbreak of the world energy crisis, energy saving technology has been paid attention to by various industries, but the hydraulic system has many energy conversion, its energy consumption is larger than electrical transmission and mechanical transmission, and hydraulic oil causes potential environmental pollution and oil loss. In addition, the noise of hydraulic system is also high, and today its application field is being compressed by other transmission technologies. One of the directions of the development of hydraulic system in the future is how to reduce the energy consumption of hydraulic system. Improve the energy-saving technology of hydraulic system. Therefore, we can achieve high efficiency and energy saving while ensuring the performance requirements and reliability. This is very important for hydraulic control system. Most of the existing energy-saving control technology is only suitable for pump control system, but the energy-saving technology in valve control system needs to be broken through. Therefore, the study of a control valve which can not only guarantee high response performance but also eliminate the repeated throttling loss to achieve energy saving can open a new way for the energy-saving technology in the valve control system. According to the basic theory of integrated high performance energy saving control valve, this paper studies the energy saving control of integrated high performance energy saving control valve. Single side throttling control is carried out according to the requirement of working condition to eliminate the repeated throttling loss of conventional control valve due to the mechanical fastening of throttling edge. And the purpose of energy saving is realized by applying differential circuit to regenerate flow. This paper studies the principle and control strategy of energy saving by using integrated valve under various working conditions, and realizes the cooperative control method of high energy saving control based on many basic units. The theoretical analysis and experimental results show that the efficiency of hydraulic system can be greatly improved by using integrated valve. This study opens a new way to improve the efficiency of valve control system. And lay a theoretical and technical foundation for the industrial application of the control valve.
