Problems solved by technology

For natural river water with a lot of sediment and relatively hard sediment particles, because the sediment is easy to cause serious wear and damage to the bearings and seals of the motor drive system, ordinary long-axis deep well pumps can no longer work normally in this environment.

Embodiment 1

[0046] Example 1: Combining figure 1 ,as well as Figure 5 to Figure 10 . like figure 1 The schematic structural diagram shown is a deep well pump, which includes an upper casing 1 , a filter cover 2 and a lower casing 3 . The filter cover 2 is disposed between the upper casing 1 and the lower casing 3 , and the lower casing 3 is provided with a first filter mesh structure 400 that can be turned outward.

[0047] The first filter screen structure 400 includes a plurality of net covers 401, a hinge 402 connecting the net covers 401 and the lower housing 3, a first magnet 403 fixed on the end of the net cover 401 away from the hinge 402, and arranged inside the lower housing 3 There is an electromagnetic mechanism 404 for forming the same or opposite magnetic field as the first magnet 403 . The mesh cover 401 adopts a light wire mesh structure, and may also adopt a plastic structure. The hinge 402 allows the net cover 401 to rotate. Since the net cover 401 is separated from e...

Embodiment 2

[0067] Embodiment 2: Based on the design concept of Embodiment 1, the upper casing 1 is provided with a second filter mesh structure 500 . The second filter mesh structure 500 is the same as the first filter mesh structure 400 , the hinge 402 is arranged at the upper end of the mesh cover 401 , and the first magnet 403 is arranged at the lower end of the mesh cover 401 . According to this design, when the sediment flows from top to bottom, due to the second filter mesh structure 500, the sediment can be accumulated from the middle to both sides through the inverted funnel structure. When the deep well pump is not working, it will be The net cover 401 is closed, and the sediment accumulated on the side wall can fall freely and sink. The second filter screen structure 500 is set on the upper shell 1, thereby increasing the second filtering effect. Since the deep well pump is working, the well The wall may also cause sediment to fall, so this design further improves the filtering...

Embodiment 3

[0068] Implementation 3: The difference from Embodiment 2 is that: the hinge 402 is arranged at the lower end of the mesh cover 401 , and the first magnet 403 is arranged at the upper end of the mesh cover 401 . The arrangement of the second filter net structure 500 and the first filter net structure 400 upside down is beneficial to the accumulation and collection of sediment. The switching circuit 9 is used to perform cycle timing to enable each detection device, thereby embodying automation and intelligence.

Abstract

The invention discloses a deep-well pump and provides an electric control automatic sand-proof deep-well pump to solve the problem that a deep-well pump is prone to being affected by silt during underground work. According to the technical scheme, the deep-well pump comprises an upper shell, a filter cover and a lower shell; the filter cover is arranged between the upper shell and the lower shell which is provided with a first filter net structure capable of being overturned towards the outside; the first filter net structure comprises a plurality of net covers, hinge pieces used for connecting the net covers with the lower shell, and first magnets fixed to the ends, deviating from the hinge parts, of the net covers; and the inner side of the lower shell is provided with electromagnetic mechanisms, and the first magnets and the electromagnetic mechanisms form homopolar magnetic fields or heteropolar magnetic fields correspondingly. The intelligent sand-proof and desanding effects are achieved.

Description

technical field [0001] The invention relates to the technical field of deep well pumps. Background technique [0002] Deep well pump is a general-purpose water-lifting machine in which the motor and the water pump are directly connected and submerged into the water. The blades rotate together to do work on the liquid under the action of centrifugal force, converting mechanical energy into liquid energy, and the well water flies away from the impeller and shoots out. The speed of the injected liquid gradually slows down in the diffusion chamber of the pump casing, and the pressure gradually increases, and then from the pump The discharge pipe of the outlet flows out. The deep well pump is actually a vertical single-suction segmented multi-stage centrifugal pump. [0003] The selection of the deep well pump should be correctly selected according to the characteristics of the construction site. The deep well pump has strict requirements on the sand content in the water, which...
