Embodiment 1

[0036] Embodiment 1: as figure 1 , figure 2 As shown, a submersible pump includes a pump body 1 and a motor 2. A pump shaft 11 is connected to the pump body 1 for vertical rotation. The pump shaft 11 is provided with an impeller 12 located in the pump body 1. The lower end surface of the pump body 1 A water inlet 3 is provided, and a drainpipe 4 connected to the inside is arranged on the side wall bent upward.

[0037] When the above-mentioned submersible pump is in use, the motor 2 is used to drive the pump shaft 11 to rotate. At this time, the pump shaft 11 drives the impeller 12 to rotate synchronously, and the water flow is sucked into the pump body 1 along the water inlet 3, and then the water flow is drawn along the drain pipe. 4 discharge, realize the suction and discharge of water flow.

[0038] like figure 2 As shown, a cutting disc 31 is horizontally arranged in the water inlet 3 , and a plurality of water inlet holes 32 run through the cutting disc 31 . A cutt...

Embodiment 2

[0053] Embodiment 2: as Figure 5 As shown, a submersible pump differs from Embodiment 1 in that a mounting ring 44 is provided on the outer wall of the upper end of the drain pipe 4, and a mounting sleeve 45 is provided on the upper end surface of the mounting ring 44, and the outer wall of the drain pipe 4 and the mounting sleeve 45 An installation gap 46 is formed between the inner walls, and a viewing hole 451 communicating with the installation gap 46 runs through the outer wall at the lower end of the installation sleeve 45 .

[0054] like Figure 5 As shown, the outer wall of the upper end of the drain pipe 4 is provided with a multi-ring ring gear 47, and the multi-ring ring gear 47 is located inside the installation sleeve 45. uniformly distributed in the axial direction.

[0055] When it is necessary to install the water pipe on the drain pipe 4, first set the water pipe on the outer wall of the drain pipe 4, and then drive the water pipe to move downward. down ex...

Abstract

The invention discloses a submersible pump, which relates to the field of water pumps. It includes a pump body and a drainage pipe arranged on the pump body. The side wall of the pump body is provided with a support seat, and the upper end surface of the support seat is vertically rotatably connected with a rotating shaft. The support seat is provided with a locking part for fixing the rotating shaft; the upper end of the rotating shaft is horizontally provided with a circular switch plate, the drain pipe is provided with a through hole for the switch plate to slide, and the switch plate is provided with a plurality of connecting holes of different specifications , a plurality of connection holes are evenly distributed along the circumferential direction of the switch plate, and are used to communicate with the drain pipe. The present invention has the following advantages and effects: by setting connecting holes with different diameters to communicate with the drainage pipes, the adjustment of the cross-sectional area of ​​the water flow can be realized, and the water pressure at the discharge position of the water flow can be changed, so as to realize the head adjustment of the water flow, so that the above-mentioned submersible pump can be adapted It is matched with different head requirements to achieve the effect of high adaptability.

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] When the traditional submersible pump is in use, the head at the position of the drain pipe usually remains unchanged, so the head at the position of the drain pipe cannot be adjusted according to different usage requirements, and the adaptability is low, which needs to be improved. Contents of the invention [0004] The object of the present invention is to provide a submersible pump with a high adaptability effect. [0005] The technical purpose of the present invention is achieved through the following technical solut...
