The invention discloses a novel heat radiation vertical marine self-absorption centrifugal pump which comprises a pump body (1). A water inlet (2) is formed in the pump body (1), a water retaining ring (3) is arranged above the pump body (1) and connected with a coupler (4), the coupler (4) is connected with a motor (5), and a water outlet (6) is formed in the other side of the pump body (1). A heat radiator (7) is mounted outside the motor (5). The novel heat radiation vertical marine self-absorption centrifugal pump has the beneficial effects of being reasonable in design and simple in structure. When the novel automatic exhausting mixed-flow pump works, the expected effect can be achieved, most pumps need anti-explosion requiring configurations, but the material of the novel flow-controlled vertical marine self-absorption centrifugal pump meets the requirement, a reinforced composite is adopted, the novel heat radiation vertical marine self-absorption centrifugal pump is reinforced,and use safety is improved. The heat radiator is mounted outside the motor, and the pump is not too hot when working.
Description
technical field [0001] The invention relates to the field of ships, in particular to a novel radiating vertical marine self-priming centrifugal pump. Background technique [0002] The self-priming centrifugal pump can send water out because of the centrifugal force. Before the pump works, the pump body and the water inlet pipe must be filled with water to form a vacuum state. When the impeller rotates rapidly, the blades make the water rotate quickly, and the rotating water flies away from the impeller under the action of centrifugal force. After the water is thrown, the central part of the impeller forms a vacuum area. Under the action of atmospheric pressure (or water pressure), the water in Suyuan is pressed into the water inlet pipe through the pipe network. The circulation is endless like this, just can realize continuous pumping. It is worth mentioning here that the self-priming centrifugal pump must be filled with water in the pump casing before starting, otherwise...
