Description

Technical Field

[0001] The utility model relates to the technical field of pumps, in particular to a pump with a counterweight. Background Art

[0002] Existing water pumps are equipped with internal counterweights to drive the pump to the bottom of the corresponding container to suck the liquid. Common counterweights require the use of molds to produce specific shapes for different pump bodies, but this leads to high mold opening costs. Alternatively, production methods such as sand casting and sheet metal stamping require the production of counterweights with corresponding shapes for different pump body structures. Complex shapes are more difficult to produce.

[0003] Moreover, the produced counterweight blocks usually need to be punched and then fixed to the pump body with screws, which requires many assembly steps and has low production efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a pump with a counterweight, which has the advantages of convenient production and low cost.

[0005] In order to achieve the above objectives, the solution of the present invention is:

[0006] A pump with a counterweight, comprising a pump body and a counterweight structure fixed to the pump body;

[0007] The counterweight structure includes a counterweight groove formed on the pump body, and a plurality of counterweight sands and coagulating materials filled in the counterweight groove;

[0008] The coagulation material coagulates each counterweight sand into a whole and fixes it in the counterweight groove.

[0009] Furthermore, the counterweight sand is iron sand or steel sand.

[0010] Furthermore, the condensing material is resin, liquid silicone or polyurethane.

[0011] Furthermore, a block is protruded from the side wall of the counterweight groove.

[0012] Furthermore, there are multiple blocks, which are distributed at intervals along the circumferential direction of the side wall of the counterweight groove.

[0013] Furthermore, the pump body includes an upper shell and a lower shell, which are fixed to each other and form a pump body space, a suction structure is installed in the pump body space, and the counterweight structure is arranged on the upper shell.

[0014] Furthermore, the counterweight groove is integrally formed on the bottom surface of the upper shell.

[0015] Furthermore, the coagulation material blocks the notch of the counterweight groove, and the counterweight sand is hidden inside the coagulation material.

[0016] After adopting the above technical scheme, by directly forming a counterweight groove on the pump body, and then filling the counterweight groove with low-cost counterweight sand, the counterweight sand can adaptively fill the counterweight groove and can adapt to counterweight grooves of various complex shapes. Then, the condensing material is poured into the counterweight groove to condense and fix the counterweight sand into one and form an integrated structure with the counterweight groove. This can effectively realize the counterweight setting of the pump body, increase the weight of the pump body, and meet the purpose of bottom suction of the pump. Moreover, the counterweight structure itself is not only simple in structure and low in cost, but also easy to produce and highly practical. It can be applied to various types of pumps without the need for additional mold production of counterweight blocks and the need for additional assembly of counterweight blocks. It can effectively reduce production costs, improve production efficiency, and enhance product competitiveness. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed with various different counterweights.

[0022] like Figures 1 to 3 As shown, a pump with a counterweight in this embodiment includes a pump body 1 and a counterweight structure 2 fixed to the pump body 1 .

[0023] The counterweight structure 2 includes a counterweight groove 21 formed on the pump body 1 , and a plurality of counterweight sands 22 and a coagulating material 23 filled in the counterweight groove 21 ; the coagulating material 23 coagulates the counterweight sands 22 into one and fixes them in the counterweight groove 21 .

[0024] In this way, by directly forming the counterweight groove 21 on the pump body 1, and then filling the counterweight groove 21 with low-cost counterweight sand 22, the counterweight sand 22 can adaptively fill the counterweight groove 21, and can adapt to counterweight grooves 21 of various complex shapes. Thereafter, the condensing material 23 is poured into the counterweight groove 21, so that the counterweight sand 22 is condensed and fixed into one and forms an integrated structure with the counterweight groove 21, which can effectively realize the counterweight setting of the pump body 1 and increase the weight of the pump body 1 to meet the bottom suction purpose of the pump; and the counterweight structure 2 is not only simple in structure and low in cost, but also easy to produce and highly practical, and is suitable for various types of pumps. There is no need for additional mold production of counterweight blocks, and no need for additional assembly of counterweight blocks, which can effectively reduce production costs, improve production efficiency, and enhance product competitiveness.

[0025] The weight sand 22 is a granular object with high sealing performance. In this embodiment, the weight sand 22 can be iron sand, steel sand, etc.

[0026] The condensation material 23 in this embodiment is resin as an example, but other materials such as liquid silicone, polyurethane, etc. may also be used.

[0027] Iron sand and steel sand have high density, large weight and low cost, while the condensing material is resin, and the existing glue filling machine can be used to directly perform the glue filling operation. After the resin A glue and B glue are mixed in a certain proportion, they can be poured into the counterweight groove 21 in liquid form, and fill the gaps between the counterweight sand 22 and the gaps between the counterweight sand 22 and the counterweight groove 21. After waiting for the resin to solidify, all the counterweight sand 22 can be condensed into one and firmly bonded in the counterweight groove 21 to form the counterweight structure 2.

[0028] In order to further improve the fixing effect between the resin and the counterweight groove 21, a block 211 may be protruded from the side wall of the counterweight groove 21. There may be multiple blocks 211, which are distributed at intervals along the side wall of the counterweight groove 21.

[0029] In this embodiment, the counterweight groove 21 is in the shape of a rectangular groove, and a block 211 protrudes from the middle position of each of the four side walls of the rectangular groove. Therefore, when the resin is poured into the counterweight groove 21 in liquid form and formed, each block 211 can clamp the solid resin, further preventing the resin and other condensed materials 23 from falling out of the counterweight groove 21.

[0030] Specifically, the pump body 1 of this embodiment includes an upper shell 11 and a lower shell 12. The upper shell 11 and the lower shell 12 are fixed to each other and form a pump body space 13. A suction structure (not shown) is installed in the pump body space 13 for pumping water, and the counterweight structure 2 can be integrally formed on the bottom surface of the upper shell 11; and the condensing material 23 usually directly blocks the notch 212 of the counterweight groove 21, so that the counterweight sand 22 is hidden inside the condensing material 23.

[0031] Therefore, the counterweight sand 22 can be protected, the counterweight structure 2 has high corrosion resistance, the service life of the counterweight structure 2 can be prolonged, the counterweight structure 2 is prevented from being corroded and reduced in weight, and good counterweight effect is ensured.

[0032] The preferred embodiments of the utility model are described above, the protection scope of the utility model is not only limited to the above-mentioned embodiments, and all technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be noted that equivalent changes and modifications without departing from the principle of the utility model are still within the protection scope of the utility model for ordinary technical personnel in the technical field.
