一、序言随着我国社会主义革命和社会主义建设的飞速发展,许多行业对机床制造业提出了许多新的要求。我厂即将试制的新产品,高精度立式磨床和液压半自动仿形立车QI-031,对液压进给方面要求低速、稳定。这在一般节流调速的液压传动系统中用的普通节流阀是很难实现的。我厂根据伟大领袖毛主席关于“中国应当对于人类有较大的贡献”和“自力更生,艰苦奋斗”的教导,工人、革命技术人员和领导干部紧密结合,彻底批判和清算“爬行主义”、“洋奴哲学”等一系列反革命修正主义的科技路线,开展了新型液压元件——电动节流阀的研制工作,在较短的时间内,克服了重重困难,终于获得了初步的成功。
I. Introduction With the rapid development of China’s socialist revolution and socialist construction, many industries have put forward many new requirements on the machine tool manufacturing industry. Our factory is about to trial production of new products, high-precision vertical grinder and hydraulic semi-automatic profile car QI-031, the hydraulic feed requirements of low speed and stability. This general throttling speed of the hydraulic transmission system used in ordinary throttle is very difficult to achieve. According to the guidance of Chairman Mao on behalf of the great leader, “China should make greater contribution to mankind,” and “self-reliance and hard work”, workers, revolutionary technicians and leading cadres are thoroughly integrated to thoroughly criticize and liquidate the “ A series of counter-revolutionary revisionist scientific and technological routes such as ”Creepism“ and ”Western Slavery Philosophy" were launched. The development of a new type of hydraulic element, the electric throttle valve, has been carried out. Over a relatively short period of time, numerous difficulties were overcome and finally obtained The initial success.
