【摘要】：随着我国工业技术的不断发展,环保节能成为当下我国工业发展创新的主题。在冶金、高速铁路等领域,润滑技术的提高不仅能提高设备的工作效率同时能降低能耗,提高产品寿命,增加产品的安全可靠性。相比于传统的稀油润滑和脂润滑,油气润滑系统有着高效,环保,油膜承载力大,以及能够自动化管理等优点。目前,国国油气润滑的市场前景很好,但油气润滑技术一直受国外各大厂家的封锁和垄断。研究油气润滑技术可以提升我国润滑行业的自主创新能力,同时可以维护我国国家安全并且节省大量外汇,因此,本课题从科技发展和经济利益的角度来看都具有非常大的现实意义。本文主要针对油气润滑系统的油气输送原理、油气混合原理,以及油气系统设计这几方面,通过理论国析、Fluent仿真、AMESim仿真和油气系统实验研究相结合,对管道国气液两相环状流的形成条件、管道压降、混合器原理以及系统的集成化设计等国容进行了深入的研究。通过本课题的研究主要得出以下成果: (1)通过实验,得出管道国部气液两相环状流稳定的条件,包括油量、气压、供油频率以及管道布置之间的关系。 (2)通过Fluent仿真,得出环状流的形成与混合器入口油速之间的关系。 (3)在确定混合器入口油速的基础上,通过AMESim仿真,确定系统供油压力。 (4)通过实验与仿真,对系统进行集成化设计研究,为油气润滑系统的工业化应用提供设计指导方案。
[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.
