【摘要】：減壓塔是石化行業(yè)中應(yīng)用廣泛的單元操作設(shè)備。泵是化工生產(chǎn)中應(yīng)用比較廣泛的動(dòng)力設(shè)備,它像人的心臟一樣源源不斷的為化工生產(chǎn)工藝管線提供“血液”—各種各樣的化工生產(chǎn)介質(zhì)、原料。離心泵由于具有結(jié)構(gòu)簡單、流量均勻、操作費(fèi)用低、維修工作量小等特點(diǎn)使其在化工行業(yè)得到了較多的應(yīng)用。管道就像是人體的血管,通過管道將各種介質(zhì)、原料運(yùn)送到各種設(shè)備中進(jìn)行不同的工藝處理,并最終產(chǎn)生我們所需要的產(chǎn)品。管道是連接各種化工設(shè)備的橋梁和中介,為確�；どa(chǎn)的安全、正常運(yùn)行,對泵進(jìn)出口的管道進(jìn)行應(yīng)力分析就顯得很有必要。化工行業(yè)的迅速發(fā)展也使管道應(yīng)力分析受到越來越多的重視。同時(shí)計(jì)算機(jī)的日新月異的發(fā)展也為管道應(yīng)力分析提供了有力支持。對減壓塔底泵進(jìn)出口管道進(jìn)行應(yīng)力分析,為化工實(shí)際安全生產(chǎn)提供數(shù)據(jù)支持,是當(dāng)前社會(huì)發(fā)展、工業(yè)生產(chǎn)的趨勢。本文利用管道應(yīng)力分析軟件CAESARII 2013 R1,以減壓塔底離心泵為模擬研究對象對泵進(jìn)出口管道進(jìn)行應(yīng)力分析,在與標(biāo)準(zhǔn)規(guī)范進(jìn)行對比后,對于應(yīng)力過大、管道柔性不足的地方進(jìn)行調(diào)整和修改,經(jīng)過多方面的調(diào)整最后得到比較好的設(shè)計(jì)方案。通過改變管道溫度、壓力等得到影響減壓塔底泵進(jìn)出口管道應(yīng)力的因素,為化工生產(chǎn)、設(shè)計(jì)開發(fā)模擬優(yōu)化提供豐富的數(shù)據(jù)支持和一定的理論指導(dǎo)。本文進(jìn)行研究的主要工作：(1)歸納總結(jié)了前人在管道應(yīng)力分析方面的基礎(chǔ)理論、應(yīng)力分析的發(fā)展、應(yīng)力分析的目的以及重要性等方面的研究,闡述了國內(nèi)外在管道應(yīng)力分析方面的發(fā)展情況,對本文進(jìn)行減壓塔底泵進(jìn)出口管道的應(yīng)力分析提供強(qiáng)有力的理論支持。(2)利用應(yīng)力分析模擬軟件CAESAR Ⅱ,結(jié)合前人的理論基礎(chǔ)知識,建立減壓塔底泵進(jìn)出口管道應(yīng)力分析數(shù)值模型,通過對減壓塔底泵進(jìn)出口管道的物理模型建立、模擬計(jì)算、分析、調(diào)整修改,得到比較好的設(shè)計(jì)方案。(3)研究了溫度、壓力對減壓塔底泵進(jìn)出口管道應(yīng)力的影響。
[Abstract]:Vacuum tower is a widely used unit operation equipment in petrochemical industry. Pump is a kind of power equipment which is widely used in chemical production. It is like the heart of human being. It provides "blood"-various chemical production medium and raw material for the pipeline of chemical production process continuously. Centrifugal pump has been widely used in chemical industry because of its simple structure, uniform flow rate, low operating cost and low maintenance workload. Pipes are like blood vessels in the human body, through which all kinds of media and materials are transported to various equipment for different processes, and eventually the products we need are produced. Pipeline is a bridge and intermediary connecting all kinds of chemical equipment. In order to ensure the safety and normal operation of chemical production, it is necessary to analyze the stress of the pipe at the inlet and outlet of the pump. With the rapid development of chemical industry, more and more attention has been paid to pipeline stress analysis. At the same time, the rapid development of computer also provides a strong support for pipeline stress analysis. The stress analysis of the inlet and outlet pipeline of the vacuum tower bottom pump is the trend of the current social development and industrial production to provide data support for the practical safety production of chemical industry. In this paper, the stress analysis of the inlet and outlet of the pump is carried out by using the software CAESARII 2013 R1 and the centrifugal pump at the bottom of the decompression tower as the simulation object. After comparing with the standard specification, the stress is too large. The pipeline is not flexible enough to adjust and modify, after a variety of adjustments to get a better design. By changing the temperature and pressure of the pipeline, the factors affecting the stress of the inlet and outlet pipeline of the vacuum tower bottom pump are obtained, which provide abundant data support and certain theoretical guidance for chemical production, design and development simulation optimization. The main work of this paper is to sum up the basic theory of stress analysis of pipelines, the development of stress analysis, the purpose and importance of stress analysis, etc. The development of pipeline stress analysis at home and abroad is described, and a powerful theoretical support is provided for the stress analysis of the inlet and outlet pipeline of the decompression tower bottom pump in this paper. The stress analysis simulation software CAESAR 鈪，
