【摘要】：流體密封技術(shù)在當(dāng)前的石化行業(yè)范圍內(nèi)應(yīng)用的十分普遍,石化行業(yè)生產(chǎn)、輸送的介質(zhì)大都具有高溫高壓、易燃易爆、有毒有害的性質(zhì),一旦泄漏至大氣環(huán)境中,不僅浪費(fèi)物料、造成裝置停車,給企業(yè)帶來(lái)經(jīng)濟(jì)損失,還會(huì)危害大氣環(huán)境及人身生命安全。由此可見(jiàn),密封的安全平穩(wěn)運(yùn)行極為重要。研究流體密封技術(shù),對(duì)石化行業(yè)機(jī)泵的平穩(wěn)有效運(yùn)轉(zhuǎn)具有十分積極的意義,尤其對(duì)大型關(guān)鍵壓縮機(jī)組的平穩(wěn)運(yùn)行起著極其重要的作用。本文針對(duì)催化裝置富氣壓縮機(jī)和重油加氫裝置循環(huán)氫氣壓縮機(jī),在密封應(yīng)用過(guò)程中出現(xiàn)的問(wèn)題,通過(guò)密封解體分析及相關(guān)理論計(jì)算,進(jìn)行了以下兩方面的研究和改造：(1)催化裝置富氣壓縮機(jī)的充氣式迷宮密封進(jìn)行了改造,催化裝置富氣壓縮機(jī)最初使用簡(jiǎn)單的充氣式迷宮密封,該套密封使用效果不佳,在機(jī)組運(yùn)行半年后就會(huì)出現(xiàn)密封泄漏跡象,檢查發(fā)現(xiàn)迷宮密封部件損壞,因此機(jī)組無(wú)法按照公司要求實(shí)現(xiàn)長(zhǎng)周期運(yùn)行。本文通過(guò)研究改造,在原密封的基礎(chǔ)上增加抽氣設(shè)施,保證了密封安全平穩(wěn)使用,實(shí)現(xiàn)了該機(jī)組的長(zhǎng)周期運(yùn)轉(zhuǎn)。(2)文中針對(duì)重油加氫裝置的循環(huán)氫氣壓縮機(jī)浮環(huán)密封出現(xiàn)過(guò)的問(wèn)題,在分析密封浮環(huán)受力的基礎(chǔ)上,對(duì)浮環(huán)密封進(jìn)行靜力性計(jì)算,找出浮環(huán)密封損壞失效的影響因素。針對(duì)這些因素,進(jìn)行對(duì)比分析,找出其中切實(shí)可行且經(jīng)濟(jì)效益和安全效益可觀的改造方法,對(duì)密封進(jìn)行相應(yīng)改造。改造后的密封通過(guò)多次的使用驗(yàn)證,達(dá)到了預(yù)期效果。
[Abstract]:Fluid sealing technology is widely used in the petrochemical industry at present. Most of the medium produced and transported in petrochemical industry has the properties of high temperature and pressure, flammable and explosive, toxic and harmful. Once leaking into the atmosphere, it is not only a waste of material, It causes device parking, brings economic loss to enterprises, and endangers atmospheric environment and personal life safety. Thus, the safety and smooth operation of the seal is extremely important. The study of fluid sealing technology is of great significance to the smooth and effective operation of the pump in petrochemical industry, especially to the smooth operation of large key compressor units. In this paper, according to the problems existing in the sealing process of the rich gas compressor in the catalytic unit and the circulating hydrogen compressor in the heavy oil hydrogenation unit, through the analysis of the disassembly of the seal and the relevant theoretical calculation, The following two aspects have been studied and reformed: (1) the gas-filled labyrinth seal of the rich gas compressor of the catalytic unit has been reformed, and the simple gas-filled labyrinth seal was initially used in the catalytic unit rich gas compressor, and the effect of this set of seals is not good. Six months after the operation of the unit will appear signs of seal leakage, inspection found that the labyrinth seal parts are damaged, so the unit can not according to the requirements of the company to achieve a long period of operation. In this paper, through the research and transformation, the air extraction facilities are added to the original seal to ensure the safe and stable use of the seal. The long period operation of the unit has been realized. (2) aiming at the problems of floating ring seal of circulating hydrogen compressor in heavy oil hydrogenation unit, the static calculation of floating ring seal is carried out on the basis of analyzing the force of floating ring. Find out the factors that affect the failure of floating ring seal. In view of these factors, this paper makes a comparative analysis, finds out the feasible and economic and safety benefit of the revamping method, and carries on the corresponding transformation to the seal. The improved seal has been verified many times and the desired effect has been achieved.
