【摘要】：近年來,國內(nèi)的煉化行業(yè)發(fā)生了多起由于高危介質(zhì)泄漏引起的爆炸事件,造成了不良的社會(huì)影響。本論文對(duì)高危介質(zhì)工況的特性進(jìn)行了研究和分析,發(fā)現(xiàn)現(xiàn)有的高危泵密封輔助裝置存在安全缺陷。煉化行業(yè)對(duì)高危介質(zhì)泵的改造勢在必行,研發(fā)新的高危泵機(jī)械密封輔助裝置是解決問題的關(guān)鍵,具有良好的市場前景。 本論文總結(jié)了機(jī)械密封輔助裝置的作用；介紹了高危泵機(jī)械密封輔助裝置常用的設(shè)備；推導(dǎo)了機(jī)械密封輔助裝置常用的計(jì)算公式;介紹了機(jī)械密封輔助裝置常用的輔助方案。對(duì)國內(nèi)現(xiàn)有高危泵機(jī)械密封輔助裝置和機(jī)械密封的布置方式進(jìn)行了分析,得出了現(xiàn)有高危泵機(jī)械密封輔助裝置和機(jī)械密封布置方式存在的問題。根據(jù)現(xiàn)有高危泵機(jī)械密封輔助裝置和布置方式存在的問題,以及高危泵的特性結(jié)合國內(nèi)外現(xiàn)有技術(shù)提出了高溫油泵、輕烴泵、有毒有害介質(zhì)泵的機(jī)械密封輔助裝置解決的具體方案。將機(jī)械密封的布置方式由單端面改為雙端面密封,避免了高溫油泵主密封的損壞,高溫易燃介質(zhì)外漏造成的危險(xiǎn);實(shí)現(xiàn)了輕烴泵、有毒有害介質(zhì)泵的零溢出。 通過對(duì)機(jī)械密封布置方式和機(jī)械密封輔助裝置的改進(jìn),解決了現(xiàn)有高危泵機(jī)械密封及輔助裝置存在的問題。本論文所提出的高危泵輔助裝置解決方案經(jīng)過了現(xiàn)場的檢驗(yàn),證明是安全有效的,為企業(yè)創(chuàng)造了良好的經(jīng)濟(jì)效益。
[Abstract]:In recent years, there have been many explosion events caused by high risk medium leakage in domestic refining and chemical industry, which has caused bad social impact. In this paper, the characteristics of high-risk medium working condition are studied and analyzed, and it is found that the existing high-risk pump sealing auxiliary device has safety defects. It is imperative to reform the high risk medium pump in the refining and chemical industry. It is the key to solve the problem and has a good market prospect to develop a new mechanical seal auxiliary device for the high risk pump. This paper summarizes the function of mechanical seal auxiliary device, introduces the equipment commonly used in mechanical seal auxiliary device of high risk pump, deduces the commonly used calculation formula of mechanical seal auxiliary device, and introduces the commonly used auxiliary scheme of mechanical seal auxiliary device. This paper analyzes the arrangement of mechanical seal auxiliary device and mechanical seal of high risk pump in China, and points out the existing problems of mechanical seal auxiliary device and mechanical seal arrangement of high risk pump. According to the problems existing in the mechanical seal auxiliary device and arrangement mode of the high risk pump and the characteristics of the high risk pump combined with the existing technology at home and abroad, the high temperature oil pump and the light hydrocarbon pump are put forward. The concrete scheme of solving the mechanical seal auxiliary device of toxic and harmful medium pump. The arrangement of mechanical seal is changed from single face to double end seal to avoid the damage of main seal of high temperature oil pump and the danger caused by leakage of high temperature flammable medium, and the zero overflow of light hydrocarbon pump and toxic and harmful medium pump is realized. By improving the arrangement of mechanical seal and the auxiliary device of mechanical seal, the existing problems of mechanical seal and auxiliary device of high risk pump are solved. The solution of the high risk pump auxiliary device presented in this paper has been tested on the spot and proved to be safe and effective, which has created good economic benefits for the enterprise.
