In the middle pressure chamber upside sets floating seal device, so vortex top and middle pressure by exhaust pressure role.
在中间压力腔上部设有浮动密封装置，因此涡旋顶部受排气压力与中间压力作用。

Curves of axial temperature affected by different inlet press and geometrical structures of vortexchamber were drawn according to the measuring results.
根据实测结果，得到了进气压力及涡流室几何结构对涡流管部分轴线温度分布的影响曲线。
