【摘要】：隨著我國工業(yè)技術(shù)的不斷發(fā)展,環(huán)保節(jié)能成為當下我國工業(yè)發(fā)展創(chuàng)新的主題。在冶金、高速鐵路等領(lǐng)域,潤滑技術(shù)的提高不僅能提高設備的工作效率同時能降低能耗,提高產(chǎn)品壽命,增加產(chǎn)品的安全可靠性。相比于傳統(tǒng)的稀油潤滑和脂潤滑,油氣潤滑系統(tǒng)有著高效,環(huán)保,油膜承載力大,以及能夠自動化管理等優(yōu)點。目前,國國油氣潤滑的市場前景很好,但油氣潤滑技術(shù)一直受國外各大廠家的封鎖和壟斷。研究油氣潤滑技術(shù)可以提升我國潤滑行業(yè)的自主創(chuàng)新能力,同時可以維護我國國家安全并且節(jié)省大量外匯,因此,本課題從科技發(fā)展和經(jīng)濟利益的角度來看都具有非常大的現(xiàn)實意義。 本文主要針對油氣潤滑系統(tǒng)的油氣輸送原理、油氣混合原理,以及油氣系統(tǒng)設計這幾方面,通過理論國析、Fluent仿真、AMESim仿真和油氣系統(tǒng)實驗研究相結(jié)合,對管道國氣液兩相環(huán)狀流的形成條件、管道壓降、混合器原理以及系統(tǒng)的集成化設計等國容進行了深入的研究。 通過本課題的研究主要得出以下成果: (1)通過實驗,得出管道國部氣液兩相環(huán)狀流穩(wěn)定的條件,包括油量、氣壓、供油頻率以及管道布置之間的關(guān)系。 (2)通過Fluent仿真,得出環(huán)狀流的形成與混合器入口油速之間的關(guān)系。 (3)在確定混合器入口油速的基礎(chǔ)上,通過AMESim仿真,確定系統(tǒng)供油壓力。 (4)通過實驗與仿真,對系統(tǒng)進行集成化設計研究,為油氣潤滑系統(tǒng)的工業(yè)化應用提供設計指導方案。
[Abstract]:With the continuous development of industrial technology in China, environmental protection and energy conservation has become the theme of innovation in China's industrial development. In metallurgy, high-speed railway and other fields, the improvement of lubricating technology can not only improve the working efficiency of equipment, but also reduce energy consumption. Improve product life, increase product safety and reliability. Compared with traditional thin oil lubrication and grease lubrication, oil and gas lubrication system has the advantages of high efficiency, environmental protection, large oil film bearing capacity, and automatic management. The market prospect of oil and gas lubrication in China is very good, but oil and gas lubrication technology has always been blocked and monopolized by major foreign manufacturers. Research on oil and gas lubrication technology can enhance the independent innovation ability of China's lubrication industry. At the same time, it can maintain our national security and save a lot of foreign exchange. Therefore, this subject has great practical significance from the point of view of the development of science and technology and economic interests. This paper mainly aims at the oil and gas transportation principle, the oil gas mixing principle and the oil and gas system design of oil and gas lubrication system, and combines the simulation of fluent with the experimental study of oil and gas system. The formation conditions of gas-liquid two-phase annular flow in pipeline, the pressure drop of pipeline, the principle of mixer and the integrated design of the system are studied. Through the research of this topic, the main results are as follows:. 1) through experiments, the conditions for the stability of gas-liquid two-phase annular flow in the country of pipeline are obtained, including the relationship between oil quantity, gas pressure, oil supply frequency and pipeline arrangement. 2) the relationship between the formation of annular flow and the oil velocity at the inlet of mixer is obtained by Fluent simulation. On the basis of determining the inlet oil velocity of the mixer, the oil supply pressure of the system is determined by AMESim simulation. 4) through experiment and simulation, the integrated design of the system is studied, which provides the design guidance scheme for the industrial application of oil and gas lubrication system.
