摘要
本文根据流体力学理想气体一维流动的理论,导出了油蒸汽流泵的临界前级压力和扩压器喉部直径的计算公式,并且讨论了提高临界前级压力的措施。
In this paper, according to one-dimension flowing theory of ideal gas, calculation formulas of critical backing, pressure and diffuser throat diameter of oil vapour pump are introduced, and then some methods of improving critical backing pressure are discussed.
