Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1-3, the embodiment discloses an energy-saving WQD sewage pump, which includes a motor 1, a rotating shaft 6 is fixedly installed on an output shaft of the motor 1, the rotating shaft 6 is used for outputting power of the motor 1, a casing 2 with a cylindrical structure is fixedly installed at one end of the motor 1, the casing 2 is used as a working main body of the sewage pump and is used as a casing for storing water, a baffle ring 4 is arranged inside the casing 2, the baffle ring 4 divides the inside of the casing 2 into a pressure chamber and a water suction chamber, a water inlet is formed at one end of the casing 2, which is far away from the motor, and is communicated with the water suction chamber, and the water suction chamber is used as a main working space of the water pump and can be used for storing water entering the water suction chamber.

The rotating shaft 6 extends to the water suction cavity, the impeller 5 is installed on the part of the water suction cavity, the side wall of the water suction cavity is connected with the water outlet pipe 7, the rotating shaft 6 can drive the impeller 5 to rotate, and when the impeller 5 rotates, water in the water suction cavity is thrown outwards under the action of centrifugal force of the impeller 5, so that the water is discharged through the water outlet pipe 7.

The water outlet pipe 7 is provided with a connecting pipe 8 communicated with the upper end of the pressure cavity, the connecting pipe 8 can introduce water in the water outlet pipe 7 into the pressure cavity, the pressure in the pressure cavity is improved, and the water entering the pressure cavity can enter the water suction cavity under the action of the impeller 5, so that the pressure of the water suction cavity is improved. The water enters the water outlet pipe 7 together with external water to be discharged, and part of water in the water outlet pipe 7 enters the pressure cavity to circularly work, so that the pressure in the pressure cavity is improved and maintained, the pressure of the water suction cavity is further improved, and the integral pressure can be ensured. The pump body has higher working efficiency and can be conveyed farther.

In the process of water circulation of the pressure cavity and the water suction cavity, the water inlet of the water suction cavity can still suck water, so that water continuously enters the water suction cavity to be discharged.
