随着社会主义建设事业的发展,尤其是经过无产阶级文化大革命,我国的液压技术得到了飞快的进步,目前已广泛应用于机械工业中。为了尽快的研制各种新型液压元件,改进提高液压元件的老产品,独立自主、自力更生地发展液压测试技术,已成为当前迫切需要解决的问题。根据我所多年来从事液压元件试验工作的实践,自行设计制造了SZ-3数字容积效率仪(见下图)。现介绍如下:
With the development of socialist construction, especially after the great proletarian cultural revolution, the hydraulic technology in our country has made rapid progress and is now widely used in the machinery industry. In order to develop all kinds of new hydraulic components as soon as possible, improve the hydraulic components to improve the old products, independent, self-reliance and development of hydraulic testing technology, has become an urgent need to solve the problem. According to my practice of hydraulic components for many years, I designed and manufactured the SZ-3 digital volumetric efficiency meter (see below). Now introduced as follows:
