把李川江操作法正确地运用到螺旋榨油机上,必须要研究螺旋榨油机本体的构造,方能收到更大的效果,因为它是一种比较复杂的机器,特别是榨膛内部的机件,如绞丝、榨件、刮刀等完全会影响出油的优劣。为了使我们进一步学习苏联,搞通基本理论,译出此文,俾供研究和改进之参考。 Li Chuanjiang correct operation of the method to the screw press, you must study the structure of the screw press body to receive more effect, because it is a more complex machine, especially inside the press Mechanical parts, such as twisted wire, squeezed pieces, scrapers, etc. will completely affect the pros and cons of oil. In order to enable us to further study in the Soviet Union and to get through the basic theory, we have translated this article for reference for research and improvement.
