The invention provides a self-priming centrifugal pump, and belongs to the technical field of water pumps. The problem that an existing centrifugal pump is unstable in flow dividing effect is solved. The self-priming centrifugal pump comprises a pump body with a pump cavity, a volute arranged in the pump cavity and an impeller arranged in the volute, wherein the pump body is provided with a water inlet communicating with an inner cavity of the volute, the volute is provided with a water spraying opening for pumping water in the volute through the impeller, a flow guide plate is arranged in the volute, the impeller is provided with a water suction opening, the bottom of the volute is further detachably connected with a return valve, the return valve is provided with a water outlet enabling the pump cavity to communicate with the inner cavity of the volute, the flow guide plate is arranged between the water inlet and the water outlet, the water outlet is right opposite to the plate face of the flow guide plate, the flow guide plate is located on the outer side of the water suction opening, and one end of the flow guide plate faces the water suction opening and is right opposite to the water suction opening. According to the self-priming centrifugal pump, the machining difficulty of the whole centrifugal pump is reduced, and the production cost of the centrifugal pump is reduced.
Description
technical field [0001] The invention belongs to the technical field of water pumps, in particular to a self-priming centrifugal pump. Background technique [0002] The self-priming centrifugal pump uses centrifugal force to throw water out. Before the centrifugal pump is started, the pump body and the water inlet pipe must be filled with water to form a vacuum state. When the impeller rotates rapidly, the impeller promotes the water to rotate quickly. Under the action of centrifugal force, it flies out from the impeller. After the water in the pump is thrown out, the central part of the impeller forms a hollow area. When pumping water, when the centrifugal pump is started, the pump body and the water inlet pipe are not filled with water. At this time, the water thrown out of the pump cavity returns to the pump body and enters the impeller again through the return valve, but the water flow into the impeller There is a certain impact force, and it will have an impact with the...
