喷射泵的用途非常广泛,近十多年来,光是在钻探工程中的应用就有十五、六种之多。最近,国内有人利用它的原理,又研制成功了一种新型的钻探工具——喷射式冲击器。喷射器是喷射泵的主要部件,它决定着喷射泵的效率和性能。因此,对喷射泵的设计、计算,实质上主要集中在对 Jet pump uses a very wide range of applications, nearly 10 years, the application of drilling in the light there are fifteen, six as many. Recently, some people in the country used its principle to develop a new type of drilling tool - jet impactor. The injector is the main part of the jet pump, which determines the jet pump efficiency and performance. Therefore, the jet pump design, calculation, essentially focused on right
