Abstract现有电动涡旋压缩机的动涡盘沿主轴轴线方向受到轴向气体力和轴向平衡力作用,而轴向平衡力由于电动涡旋压缩机经常在变转速工况条件下运行而频繁变化,导致动涡旋盘轴向受力的不稳定性,进而影响压缩机性能。针对这一问题,利用FLUENT滑移网格技术,模拟了平衡块在不同转速下对背压腔内润滑油搅动的瞬态过程,得到了润滑油的速度云图和流线图,并发现平衡块搅动会引起轴向平衡力周期性波动,且随转速的增大,轴向平衡力幅度增大,而平均轴向平衡力减小。最后结合轴向平衡力与轴向气体力随主轴转角的变化规律,提出了变相位协调叠加轴向力的优化设计方法,计算发现该方法可使轴向平衡力振幅减小,动涡盘运行更加平稳,可为电动涡旋压缩机设计提供依据。
