Liquid driven pump or propulsive apparatus. |
摘要 |
<p>The apparatus relates to a jet pump or apparatus which displaces a main fluid by a pressurised driving liquid. The apparatus has a duct (13) to receive the main fluid, and a driving liquid manifold (14) cooperating with the duct to receive the pressurised driving liquid. First and second sets of inwardly facing jet nozzles (64, 65) are disposed adjacent a transverse plane of the duct and penetrate the duct side wall (42) to pass the driving liquid into the duct at a mixing portion (50) of the duct having a constant cross-sectional area. The first and second sets of jet nozzles are inclined at angles (71, Fig. 4; 74, Fig. 5) to the duct axis so that the first nozzles are inclined at a greater angle than the second nozzles. Efficiency of the pump is improved by admitting pressurised gas into the duct and providing the pump with a diverging outlet portion (18) to act as diffuser.</p> |
