今年八月間,我和一位同志到上海发昌机器厂,去設計一台三立方米的离心式篩浆机。这是我十多年来第一次去现埸設計,可以说是我工作上的一次革命。这次設計得到了完全的成功。在各方面协作配合下,我們設計出了一台結构合理、造价低、技术性能比现有的旧簖浆机好得多的篩浆机。去年和今年上半年,我們曾在办公室里閉門設計了两台同类型的篩浆机,花了五个月到一年的时間,而这次在现埸設計只花了二十天。当我們回到北京时,有些同志听說这么短的时間已完成了机器的設計,都感到十分惊异。 篩浆机是去除纸浆中的粗渣和节子,使纸的尘埃度减少的一种設备,过去国内很多紙厂都沒有这种装置。近几年来,国家对紙张的质量要求越来越高,許多紙厂都要求增加这种設备。但是我国现有的篩浆机技术落
In August this year, a comrade and I went to the Shanghai Fachang Machinery Factory to design a three cubic meter centrifugal screen machine. This is the first time I have gone to present design in more than a decade, and it can be said to be a revolution in my work. The design was completely successful. In cooperation with all parties, we have designed a screen machine with reasonable structure, low cost, and much better technical performance than the existing old reed pulpers. In the past year and the first half of this year, we had designed two screens of the same type in the office behind closed doors, which took five months to a year, and this time it took only twenty days to design at present. When we returned to Beijing, some comrades were very surprised to hear that such a short time had completed the design of the machine. Screening machine is a device to remove the coarse slag and knots in the pulp and reduce the dustiness of the paper. In the past, many paper mills did not have such devices. In recent years, the country’s requirements for the quality of paper have become higher and higher, and many paper mills require the addition of such equipment. But China’s existing screening machine technology falls
