Abstract
A marine self-priming pump water-spraying propulsion outer motor comprises the following components: an engine, a self-priming pump body, a water inlet pipe and a water outlet pipe. The engine is connected with the self-priming pump body. One end of the water inlet pipe is arranged on the self-priming pump body, and the other end is a water inlet of which the orientation is same with the advancing direction of the ship body. One end of the water outlet pipe is connected with the top of the self-priming pump body, and the other end is a water outlet of which the orientation is opposite from the advancing direction of the ship body. The water outlet of the water outlet pipe is provided with a nozzle. The nozzle is connected with the water outlet pipe through a universal joint. The universal joint is connected with a direction control rod. The nozzle is caused to turn through the direction control rod thereby controlling advancing direction of the ship body. According to the marine self-priming pump water-spraying propulsion outer motor, a novel propulsion mode of performing high-speed water spraying on water surface is adopted, thereby greatly reducing wave-making resistance and eddy current resistance of the ship in high-speed navigation, alleviating a contradiction which is difficult to settle in accelerating problem of a underwater water spraying propulsion mode, and acquiring high-speed, flexible and stable navigation performance.
