Problems solved by technology

However, when soft debris such as plastic bags or cloth strips pass through the water inlet, the serrated blades cannot effectively shred the soft debris, and the soft debris will still block the pump body, which needs to be improved

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 , figure 2 As shown, a submersible pump includes a motor 1 and a pump body 2. The pump body 2 is rotatably connected to a pump shaft 21, and an impeller 22 is arranged on the pump shaft 21. The lower end surface of the pump body 2 is provided with a water inlet hole 3 , and the side wall of the pump body 2 is provided with a drain pipe 4 communicating with the inside of the pump body 2 and aligned with the impeller 22 .

[0037] When using the above-mentioned submersible pump, start the motor 1, and the shaft of the motor 1 drives the pump shaft 21 to rotate. At this time, the pump shaft 21 drives the impeller 22 to rotate, and the centrifugal force generated by the rotation of the impeller 22 draws water into the pump body 2 along the water inlet hole 3. Finally, the water in the pump body 2 is discharged along the drain pipe 4.

Abstract

The invention discloses a submersible pump and relates to the field of water pumps. The submersible pump comprises an electric motor and a pump body, wherein a water inlet hole is formed in the lowerend face of the pump body; an installation ring is disposed at the water inlet hole; a plurality of shear blocks are disposed on the inner wall circumferential bulge of the installation ring; a pump shaft is in rotatable connection in the pump body; the outer wall of the lower end of the pump shaft is sleeved with an installation sleeve; a pair of shear knives are disposed on the outer wall of theinstallation sleeve; and lower ends of the shear knives are pressed against upper end faces of the shear blocks. The submersible pump disclosed by the invention has the advantages and effects that the shear knives are rotated relative to upper end faces of the shear blocks when water flows into the pump body. In this way, distances between the shear knives and the shear blocks are gradually reduced and shear force at intersections of the shear knives and the shear blocks is gradually increased, so that sundries in water flows are cut into pieces at the intersections, the pump body is protected from sundry blocking and anti-blocking effects are realized.

Description

technical field [0001] The invention relates to the field of water pumps, in particular to a submersible pump. Background technique [0002] Submersible pump is an important equipment for deep well water extraction. When in use, the whole unit is submerged in water to extract groundwater to the surface. It is an indispensable equipment for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, and ship adjustment. [0003] Chinese patent CN104265680A discloses a submersible pump. The submersible pump includes a pump body, an impeller, a water inlet and a water outlet. The water inlet is located at the lower end of the pump body. The impeller is arranged at the lower end of the pump body and is close to the water inlet. There are at least three blades arranged on the peripheral edge, the edge of the blade in the direction of rotation of the impeller and the edge of the top end are serrated, and the surface of the blade is coated with a frosted...
