在炼油或化工装置中,产品的比重是一个重要的质量控制指标。操作中,生产工人为了及时监视产品质量,调整操作,常常需要进行频繁的取样,就地人工分析。尽管如此,由于时间滞后大,不能及时调节,引起生产波动,质量难于保证。为了提高产品质量,实现生产过程自动化,我们研制了自动比重计。自1966年试制成功,在文化大革命中经过两年多的应用,于1969年又进行了较大的改进,并制成两台投入生
In refining or chemical plant, the proportion of products is an important indicator of quality control. In operation, production workers often need frequent sampling and manual analysis in order to monitor product quality and adjust operations in a timely manner. However, due to the lag time, can not be adjusted in time, causing fluctuations in production, quality is difficult to guarantee. In order to improve product quality, to achieve the automation of the production process, we developed an automatic hydrometer. Since its successful trial production in 1966 and its application to the Cultural Revolution for more than two years, it has undergone major improvements in 1969 and has made two inputs
