Applied Theory And Experiment Study On Air-Oil Lubrication System

With the continuous development of industry technology of China, energy–saving become the current industry development of China. In metallurgy, high-speed railway fields, lubrication technology can not only improve the working efficiency and reduce energy consumption, but also improve product life, increase the safety and reliability of the product. Compared with the traditional thin oil and grease lubrication, air-oil lubrication system is more efficient, more environment friendly and more easy at automation management, at the same time ,the oil film of air-oil lubrication has higher bearing capacity etc. At present, the domestic market prospect of air-oil lubrication is good, but the technology has been monopolied and blocked by foreign major manufacturers. Therefore, the oil-gas lubrication technology can exercise our lubrication of the independent innovation ability, also can maintain national security and save a lot of foreign exchange, the research has great realistic significance.This article mainly aims at the principle of conveying of oil-gas lubrication, the principle of gas mixture and the principle of system design. Through the combine study of theoretical analysis, Fluent simulation and AMESim simulation and experimental research, to find out the forming condition of two phase flow in pipe, pipe pressure drop, mixer principle and system integration design principle, etc.Through this topic research, achievements mainly as follows:(1)Through the Fluent simulation, find out the stability conditions of pipe internal two phase annular flow ,including the flowing: gas velocity and pressure, oil pressure and the correlation between them and the pipe diameter.(2)Through Fluent simulation, the relationship between the oil inlet speed of mixer and the formation of annual flow is obtained.(3)The pressure of oil supply is confirmed through the AMESim simulation based on the previous determination of the oil inlet velocity by Fluent(4)Through the system integrated design in the way of combing of experiment and simulation, to provide the corresponding design scheme to the industrial application of air-oil lubrication system.
