Résumé

The crankshaft oil pump system is an essential part in the rotary compressor. There are two kinds of crankshaft inner-hole structures for the oil pump system, such as the straight-hole and the horizontal-hole. Differences between the straight-hole and the transverse-hole are not only in the processing mode and cost, but also on the oil mass flow of the pump. In this paper, based on the CFD software, the fluid field of whole compressor exhaust chamber under different speeds is simulated, and the pressure pulsation curves of crankshaft straight-hole end and transverse-hole end are obtained, which are used as the boundary conditions of oil pump system simulation. Finally the impact of two structures with the straight-hole or the transverse-hole on the oil pump under different speeds is got. The pumping oil quantity with the transverse-hole structure is relatively low at low speed and is less than the straigh-thole structure at high speed. That means the crankshaft transverse-hole structure is more suitable for the frequency conversion compressor. The results of CFD simulation are indirectly verified by the long-term and reliable test.
