Description

Technical Field

[0001] This utility model relates to the field of wear-resistant diaphragm technology for large-flow mechanical diaphragm pumps, and in particular to a wear-resistant diaphragm for large-flow mechanical diaphragm pumps. Background Technology

[0002] A high-flow mechanical diaphragm pump is a positive displacement pump that uses a mechanical drive to move a diaphragm back and forth, thereby transporting large volumes of fluid. Its core feature is the use of a flexible diaphragm to completely isolate the drive mechanism from the medium being transported, achieving leak-free transport. It is particularly suitable for transporting corrosive, high-viscosity, particulate-containing, or high-purity media under high-flow conditions.

[0003] Existing high-flow mechanical diaphragm pumps contain a wear-resistant diaphragm, which is fitted onto a screw and fixed by the pump body. The range extender inside the diaphragm uses the screw to reciprocate the wear-resistant diaphragm. Since the deformation is greatest at the contact point between the wear-resistant diaphragm and the screw, the wear at this point is faster and more severe. Because other parts of the wear-resistant diaphragm can continue to be used, the wear-resistant diaphragm in existing integrated high-flow mechanical diaphragm pumps is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the wear-resistant diaphragm of a high-flow mechanical diaphragm pump cannot be replaced due to its vulnerability in the wear-resistant diaphragm, and to provide a wear-resistant diaphragm for a high-flow mechanical diaphragm pump.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wear-resistant diaphragm for a high-flow mechanical diaphragm pump, comprising: a wear-resistant mechanism, the wear-resistant mechanism including a wear-resistant diaphragm body, a connecting membrane I being sleeved inside the wear-resistant diaphragm body, an annular groove I being formed on the wear-resistant diaphragm body that fits with the connecting membrane I, a connecting membrane II being sleeved inside the wear-resistant diaphragm body, an annular groove II being formed on the wear-resistant diaphragm body that fits with the connecting membrane II, a clamping plate I being sleeved inside the connecting membrane I, an embedding groove I being formed on the connecting membrane I that fits with the clamping plate I, a clamping plate II being sleeved inside the connecting membrane II, an embedding groove II being formed on the connecting membrane II that fits with the clamping plate II, and a connecting mechanism being provided on the inner side of the wear-resistant diaphragm body.

[0006] In a preferred embodiment, the first connecting membrane is slidably connected to the inner wall of the wear-resistant diaphragm body, and the second connecting membrane is slidably connected to the inner wall of the wear-resistant diaphragm body.

[0007] In a preferred embodiment, the first clamping plate is slidably connected to the inner wall of the first connecting membrane, and the second clamping plate is slidably connected to the inner wall of the second connecting membrane.

[0008] In a preferred embodiment, the connecting mechanism includes an adjusting nut, one end of which is provided with a screw, and the screw is fixedly connected to the adjusting nut.

[0009] In a preferred embodiment, a washer is fitted onto the outer surface of the screw, and the washer is slidably connected to the screw.

[0010] In a preferred embodiment, a fastening nut is fitted onto the outer surface of the screw, and the fastening nut is threadedly connected to the screw.

[0011] In a preferred embodiment, the screw is slidably connected to connecting membrane one, connecting membrane two, clamping plate one, and clamping plate two.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention, by incorporating a wear-resistant mechanism, allows the wear-resistant diaphragm of a high-flow mechanical diaphragm pump to have a longer service life for its less-wear-prone parts, while easily replaceable wear-prone parts. Furthermore, the wear-resistant diaphragm body, connecting membrane one, and connecting membrane two, in conjunction with other components, can be tightly connected together without affecting the normal operation of the high-flow mechanical diaphragm pump, allowing for normal reciprocating deformation. Clamping plates one and two are provided, with their protruding parts respectively embedded in the embedding grooves one and two on the connecting membrane one and connecting membrane two. Thus, clamping plates one and two can simultaneously clamp and fix the wear-resistant diaphragm body, connecting membrane one, and connecting membrane two. The connecting mechanism, which works in conjunction with the wear-resistant mechanism, ensures that the components within the wear-resistant mechanism maintain a stable operating state.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figures 1-4 As shown, this utility model provides a technical solution: a wear-resistant diaphragm for a large-flow mechanical diaphragm pump, comprising: a wear-resistant mechanism 1, the wear-resistant mechanism 1 including a wear-resistant diaphragm body 11, a connecting membrane 12 sleeved inside the wear-resistant diaphragm body 11, an annular groove 13 on the wear-resistant diaphragm body 11 that fits into the connecting membrane 12, a connecting membrane 2 14 sleeved inside the wear-resistant diaphragm body 11, an annular groove 2 15 on the wear-resistant diaphragm body 11 that fits into the connecting membrane 2 14, and a clamping plate 16 sleeved inside the connecting membrane 12. The connecting membrane 12 has an embedding groove 17 that fits into the clamping plate 16. The connecting membrane 14 has a clamping plate 18 inside it. The connecting membrane 14 has an embedding groove 19 that fits into the clamping plate 18. The inner side of the wear-resistant diaphragm body 11 is provided with a connecting mechanism 2. The connecting membrane 12 is slidably connected to the inner wall of the wear-resistant diaphragm body 11. The connecting membrane 14 is slidably connected to the inner wall of the wear-resistant diaphragm body 11. The clamping plate 16 is slidably connected to the inner wall of the connecting membrane 12. The clamping plate 18 is slidably connected to the inner wall of the connecting membrane 14.

[0020] In this embodiment, by providing connecting membrane one 12 and connecting membrane two 14, which can cooperate with the wear-resistant diaphragm body 11 and are tightly connected into a whole under the clamping action of other components, the wear-resistant diaphragm body 11, connecting membrane one 12, and connecting membrane two 14 can form a complete wear-resistant diaphragm for a high-flow mechanical diaphragm pump. Furthermore, connecting membrane one 12 and connecting membrane two 14 can be easily replaced after damage, allowing the wear-resistant diaphragm body 11 to be used more durablely, thereby reducing the operating costs caused by replacing the wear-resistant diaphragm. Simultaneously, in terms of wear resistance... Annular groove 13 and annular groove 15 are provided on the diaphragm body 11, so that connecting membrane 12 and connecting membrane 2 14 can be embedded in the wear-resistant diaphragm body 11, thereby making them more stable when clamped and fixed later. In addition, clamping plate 16 and clamping plate 2 18 are provided, and the protruding parts of clamping plate 16 and clamping plate 2 18 can be embedded in the embedding groove 17 and embedding groove 2 19 provided on connecting membrane 12 and connecting membrane 2 14, respectively. Thus, clamping plate 16 and clamping plate 2 18 can simultaneously clamp and fix the wear-resistant diaphragm body 11, connecting membrane 12 and connecting membrane 2 14.

[0021] Example 2 like Figures 1-4 As shown, the connecting mechanism 2 includes an adjusting nut 21, one end of which is provided with a screw 22. The screw 22 is fixedly connected to the adjusting nut 21. A washer 23 is sleeved on the outer surface of the screw 22. The washer 23 is slidably connected to the screw 22. A fastening nut 24 is sleeved on the outer surface of the screw 22. The fastening nut 24 is threadedly connected to the screw 22. The screw 22 is slidably connected to the connecting membrane 12, the connecting membrane 24, the clamping plate 16, and the clamping plate 28.

[0022] In this embodiment, by setting the connecting mechanism 2, the wear-resistant diaphragm body 11, connecting membrane one 12 and connecting membrane two 14 can be tightly clamped and fixed. At the same time, the connecting mechanism 2 can also allow the wear-resistant diaphragm body 11, connecting membrane one 12 and connecting membrane two 14 to be installed in the pump body of the diaphragm pump and to be stably connected to the range extender crank connecting rod inside it. The adjusting nut 21 is set, and the adjusting nut 21 can drive the screw 22 to rotate. Thus, the operator can use the adjusting nut 21 to drive the screw 22 to be installed inside the pump body.

[0023] Working principle: like Figures 1-4As shown, in use, the components of the wear-resistant mechanism 1 can be assembled first. At this time, the clamping plate 16 is fitted onto the outer side of the screw 22, with the protruding part of the clamping plate 16 facing the embedding groove 17 on the connecting membrane 12. Then, the connecting membrane 12 is fitted onto the outer surface of the screw 22, with the protruding part of the clamping plate 16 embedded in the embedding groove 17. Finally, the wear-resistant diaphragm body 11 is fitted onto the outer surface of the screw 22, ensuring that the connecting membrane 12... The edge portion of screw 2 can be installed in the annular groove 13 on its outer surface. Similarly, the connecting membrane 14 and the clamping plate 18 are sequentially fitted onto the outer surface of screw 22. The connecting membrane 14 is first embedded in the annular groove 15 on the wear-resistant diaphragm body 11, and then the protruding part of the clamping plate 18 is embedded in the embedding groove 19 on the connecting membrane 14. After that, to maintain the stability of the components of the wear-resistant mechanism 1, the gasket 23 is fitted onto the outer surface of screw 22. The gasket 23 will fit against the outer surface of the clamping plate 218. Finally, the fastening nut 24 is threadedly connected to the screw 22, so that the fastening nut 24 can rotate and move on the screw 22 until the fastening nut 24 can tightly clamp and fix the wear-resistant mechanism 1 with the cooperation of the gasket 23 and the adjusting nut 21, so that the wear-resistant mechanism 1 can be in a stable state. Then the wear-resistant mechanism 1 is installed. At this time, the adjusting nut 21 is rotated by the auxiliary tool, so that the screw 22 can be firmly threadedly connected to the range extender component inside the high-flow mechanical diaphragm pump. Then the edge of the wear-resistant diaphragm body 11 is squeezed and fixed by the pump body and the end plate. When the entire high-flow mechanical diaphragm pump is installed, the high-flow mechanical diaphragm pump can use its range extender component to drive the screw 22 to move back and forth. The screw 22 can drive the wear-resistant diaphragm body 11, the connecting membrane 12 and the connecting membrane 24 to move back and forth in a deforming manner at the same time, so that the high-flow mechanical diaphragm pump can effectively control the fluid.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
