Abstract: Oil pump lubrication system is an essential portion of the rotary compressor for its reliability. Utilizing numerical simulation and experiment, this paper studies the oil supply system. Firstly, based on the theoretical analysis, this paper summarizes and gives out the estimation method for the oil level inside the crankshaft. Then, the simulation framework based on VOF multiphase model is established for the oil supply system. After that, the experimental equipment is designed and built, in order to validate the simulation model. The simulation shows good agreement with the experiment. Finally,based on the multiphase model, the key factors of the oil pump system are studied.
