【摘要】：由于世界能源危機(jī)的爆發(fā),節(jié)能技術(shù)被各個(gè)行業(yè)所重視,而液壓系統(tǒng)存在多次能量轉(zhuǎn)換,其能耗較電氣傳動(dòng)和機(jī)械傳動(dòng)大,而且液壓油造成潛在環(huán)境污染和油的損耗,加上液壓系統(tǒng)的噪聲也高,在能源緊張的今天其應(yīng)用領(lǐng)域正逐漸被其他傳動(dòng)技術(shù)所壓縮,液壓領(lǐng)域在未來發(fā)展的方向之一就是如何降低液壓系統(tǒng)能耗,完善液壓系統(tǒng)節(jié)能技術(shù)。因此,在保證性能要求與可靠性的同時(shí)還能實(shí)現(xiàn)高效節(jié)能,這對(duì)液壓控制系統(tǒng)來說具有非常重要的意義�，F(xiàn)有的大部分節(jié)能控制技術(shù)只適用于泵控系統(tǒng),而在閥控系統(tǒng)中的節(jié)能技術(shù)有待突破,故研究一種既保證高響應(yīng)性能又能消除重復(fù)節(jié)流損失實(shí)現(xiàn)節(jié)能的控制閥能夠?yàn)殚y控系統(tǒng)中的節(jié)能技術(shù)開辟一條新途徑。 本文根據(jù)集成式高性能節(jié)能控制閥的基礎(chǔ)理論-閥口獨(dú)立控制原理,研究集成式高性能節(jié)能控制閥的節(jié)能控制。在保證高響應(yīng)性能的前提下,依據(jù)工況要求進(jìn)行單邊節(jié)流控制,消除常規(guī)控制閥因節(jié)流邊機(jī)械固聯(lián)的重復(fù)節(jié)流損失,和通過應(yīng)用差動(dòng)回路使流量再生來實(shí)現(xiàn)節(jié)能的目的。本文研究了利用集成閥在多種工況下的節(jié)能原理與控制策略、基于多個(gè)基本單元實(shí)現(xiàn)高響應(yīng)節(jié)能控制的協(xié)同控制方法、以及集成閥的動(dòng)、靜態(tài)特性研究。理論分析和實(shí)驗(yàn)結(jié)果表明,利用集成閥可大大提高液壓系統(tǒng)的效率。本項(xiàng)研究為提高閥控系統(tǒng)的效率開辟新的途徑,并為該種控制閥的工業(yè)化應(yīng)用奠定理論和技術(shù)基礎(chǔ)。
[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.
