在毛主席的无产阶级革命路线指引下,我国的石油、化学工业突飞猛进,新建的石油化工装置犹如雨后春笋。原有的老装置也在不断地进行技术改造,增加产品品种和扩大生产能力。工艺改革的发展,对设备也就提出了更高的要求。近几年来,炼油工艺装置越来越多地采用离心泵,而离心泵轴封的泄漏历来是炼油行业设备中一个带普遍性的问题,为了使离心泵的轴封能满足不同的生产条件的需要,达到泄漏少、寿命长、运行安全,必须对现有的填料轴封进行改革,代之以新的轴封形式。几年来,我们以毛主席的哲学思想为武器,狠抓思想和政治路线方面的教育,“在实践中不断开辟认识真理的道路”,从1969年开始,在离心油泵上大力推广机械密封新技术并取得一些效果。但由于我们思想认识水平比较低,工作又很粗糙,因此,对机械密封的运行规律还没掌握,存在不少问题,有待今后进一步实践。现将我厂的机械密封情况作一浅略介绍,如有不当之处,请兄弟单位批评指教。还要说明一点:本文中机械密封型号的名称,如103、104、109、110型等,均系采用1970年燃化部、一机部联合设计的“泵用机械密封系列”所定型号,这些型号的详细结构和尺寸都另有资料,本文不再详述。
Guided by Chairman Mao’s proletarian revolutionary line, the petroleum and chemical industry in our country has been advancing by leaps and bounds. The newly built petrochemical plant is springing up. The original old devices are also ongoing technological transformation, increase product variety and expand production capacity. The development of process reform, the equipment also put forward higher requirements. In recent years, more and more oil refining process using centrifugal pumps, and centrifugal pump shaft seal leakage has always been a common problem in the refining industry equipment, in order to make the centrifugal pump shaft seal to meet different production conditions Need to achieve less leakage, long life, safe operation, the existing packing shaft seal must be reformed, replaced by a new shaft seal form. Over the past few years, we have used Chairman Mao’s philosophical thinking as a weapon, paid close attention to education in ideological and political lines, and “constantly opened up the path of truth understanding” in practice. Starting from 1969, we vigorously promoted new mechanical seal technologies on centrifugal oil pumps And achieved some results. However, due to the low level of our understanding of ideas and the rough work, the laws governing the operation of mechanical seals have not yet been mastered. There are still many problems to be further practiced in the future. Now I plant a mechanical seal for a brief introduction, if inappropriate, please brothers uniting advice. Also note that: In this article, the name of the mechanical seal model, such as 103,104,109,110-type, are used by the 1970 Ministry of combustion, a machine designed by the joint “pump mechanical seal series” set by the model, these Model details of the structure and size of the other information, this article will not be detailed.
