Abstract

The invention discloses a water inlet grille and additionally further discloses a spray pump comprising the water inlet grille and a ship. The water inlet grille is used for the spray pump of the shipand comprises a mounting plate and a plurality of longitudinal grille strips fixed to the mounting plate, and the sections of the longitudinal grille strips are each in a streamline shape. The waterinlet grille can improve the water inlet efficiency, and thus the propulsive efficiency of the spray pump is improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a water inlet grille, a jet pump and a ship including the water inlet grille. Background technique [0002] Jet pumps are mostly used as propellers in high-speed planing boats, and the jet pumps used in high-speed planing boats have higher propulsion efficiency. Due to the good maneuverability and passability of the jet pump, it is suitable for shallow water areas. As a propeller, the jet pump can also be used on small low-speed displacement ships such as lifeboats, small working rigs, and unmanned boats, but when used on low-speed displacement ships , the propulsion efficiency of the jet pump is low, therefore, the application of the jet pump on low-speed displacement ships is less. [0003] There is a close relationship between the propulsion efficiency of the jet pump and the speed of the jet. The lower the speed, the lower the propulsion efficiency of the jet pump. This is bec...
