摘要(Abstract):
本文分析了涡旋压缩机齿端流动阻力的影响。排出端的流动阻力引起过压缩损失,但在操作压力高或转速提高时,却减少了不足压缩损失,因此使最佳压缩比变得高于内部压缩比。
This paper analyses the influence of flow resistances through openings of scroll wraps. The flow resistance of discharge opening causes a overcompression loss. But When. pressure operationis high or the speed is increased, it lessens a under-compression loss. Therefore, the optimum operating pressure ratio shifts to a pressure ratio higher than the built-in pressure ratio.
