【 摘 要 】

Lubricating oil and bearing clearance are important parameters that affect the lubrication state of the compressor at this time. The main purpose of this paper is to study and optimize the influence of the lubricating oil and bearing clearance on the performance of the compressor. The losses of the different friction parts were obtained through simulation research. At the same time, via analysing the viscosity of the lubricating oil and the bearing clearance, this paper has got the best parameters and greatly improved the compressor low frequency efficiency. Through further experimental analysis, the results are in good agreement with the simulation analysis conclusions. This study is helpful to increase the low frequency efficiency in guiding the design of reciprocating compressors.
