Modeling and performances study of gas path in oil-air lubrication system

The AMEsim simulation models of the key parts is established through calculating the critical parameters in the oil-air lubrication system, based on the practical engineering, respectively in this paper. Then, the simulation models of the gas path system and the entire oil-air lubrication system are built. The relation curve of the air volume and the orifice area in pneumatic throttling valve is given by the simulations, and the influence of the pressure in lubrication chamber on the air flow and the air pressure is analyzed. The simulation results show that t the air volume is not linear with the orifice area in pneumatic throttling valve; the pressure in the lubricated chamber has a little influence on the air volume, but it has obvious influence on the pressure of the oil and the air system. All these research contents and conclusions will do supports to design and manufacture the oil-air lubrication in the near future.
