氟里昂喷射法检漏机理研究

Study of the Mechanism of Leak Hunting by Freon Spurting

假定液体穿透漏孔的毛细运动为定常运动,讨论了氟里昂喷射法检漏机理.根据泊稷叶粘滞流动定律,导出了液体漏量Δv与漏孔尺寸(d3/h),溶液物性(σ/η)和喷射时间th的定量关系。

On the base of assuming the solution capillary motion through the thin leak hole is steady flow, the mechanism of leak hunting by spurting Freon was discussed. From the Poiseuille viscose flow law, the relationship of the leak quantity, the leak hole size, the physical properties of liquor and the spurting time was discussed, and the expression of leakage rate of liquor was derived.
