Description

Technical Field

[0001] This utility model belongs to the technical field of pump body components, and in particular relates to a sand-proof guide wheel. Background Technology

[0002] Sand-resistant impellers are impellers specifically designed to cope with sandy fluid environments. Through structural optimization or material improvement, their wear resistance is enhanced to reduce the erosion of the impeller by sand particles, extend the service life of the equipment, and maintain stable performance. Large gaps are left between the blades to allow sand particles to pass through, reducing the risk of clogging. They are also made of hard alloy or stainless steel to increase the surface hardness of the impeller and resist sand particle scratching, or a rubber coating is sprayed on the blade surface to form a protective layer and reduce direct wear.

[0003] Chinese patent publication number 201721465539.X discloses a sand-resistant guide wheel, including a guide shell, an impeller inside the guide shell, a bearing on one side of the impeller, an alloy bushing fitted on the outer side of the bearing near the impeller at one end and a bushing fitted on the other end, an alloy bushing on the outer side of the alloy bushing, a lower wear-reducing pad on the guide shell, and an upper wear-reducing pad at one end of the alloy bushing. This invention provides a high-strength, wear-resistant hard alloy sleeve in the radial direction inside the guide shell, and sets an alloy bushing to cooperate with it, so as to minimize radial friction and reduce unit vibration to a minimum. This allows the unit to maintain optimal radial stability in sand-containing wells and ensure stable unit performance.

[0004] However, existing technologies have the following problems when used: The welding positioning accuracy and ease of operation are insufficient. The assembly and fixation of the impeller body and the mounting base usually rely on the welding process. However, the existing structure lacks a dedicated welding guide and positioning mechanism. During assembly, the impeller body is prone to circumferential offset or axial misalignment, resulting in excessive coaxiality deviation between the impeller and the mounting base after welding, which affects the rotational balance. At the same time, the welding area is often blocked by parts, the operating space is narrow, and it is difficult for the welding torch to accurately reach the weld position. This not only leads to incomplete welds and difficulty in cleaning weld slag, but also causes cracking of the connection due to welding stress concentration, which seriously affects the assembly strength and sealing performance. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a sand-resistant guide wheel, comprising: An impeller body, wherein a fixed base for supporting the impeller body is provided on one side of the impeller body, and a mounting component is provided at the bottom of the impeller body; The mounting base has the impeller body located at the bottom of the mounting base, and the inner cavity of the mounting base is provided with a magnetic ring; A locking element, located at the bottom of the mounting base, is used to prevent the magnetic ring from rotating independently; A cover plate is provided on the outside of the mounting base. The outside of the cover plate is provided with multiple edge portions, and a groove corresponding to the mounting component is provided between every two edge portions.

[0006] Furthermore, the mounting component includes a mounting plate, which is fixedly connected to the bottom of the impeller body. The mounting base has a matching guide groove, the mounting plate passes through the guide groove and extends into the groove. The mounting plate, the guide groove and the groove are all arc-shaped.

[0007] Furthermore, the locking component includes a connecting rod, which is fixedly connected to the bottom of the fixing base. The top of the magnetic ring has a connecting hole, and the connecting rod is located in the inner cavity of the connecting hole.

[0008] Furthermore, a support ring is fixedly connected to the bottom of the inner cavity of the mounting base, and an annular groove is opened at the bottom of the magnetic ring, with the support ring fixedly disposed in the inner cavity of the annular groove.

[0009] Furthermore, a notch is provided at one end of the groove.

[0010] Furthermore, it also includes a first contact surface and a second contact surface. The first contact surface is disposed at the lower end of the inner sidewall of the mounting base, and the second contact surface is disposed at the lower end of the sidewall of the magnetic ring. The first contact surface and the second contact surface are adapted to each other.

[0011] Furthermore, both the first and second contact surfaces have rounded corners.

[0012] Furthermore, a mounting post is fixedly connected to the middle of the inner cavity of the mounting base, and the magnetic ring is fixedly connected to the outside of the mounting post.

[0013] Furthermore, a through hole is provided at the top center of the impeller body, the fixed seat, the mounting base, and the mounting column.

[0014] Compared with the prior art, the sand-proof guide wheel of this utility model has the following advantages: 1. By fitting the mounting plate with the arc shape of the guide groove and recess, a welding guide structure is formed, which avoids the impeller body welding position from shifting. At the same time, the notch at the end of the recess provides operating space for the welding torch to extend and facilitates the cleaning of welding slag, thereby improving welding accuracy and work efficiency and ensuring welding quality.

[0015] 2. The locking component limits the magnetic ring's independent rotation by engaging with the connecting rod and the magnetic ring's connecting hole. This, combined with the increased contact area between the mounting base and the magnetic ring's first and second contact surfaces, and the multiple fixing structures of the support ring and the annular groove, and the mounting column and the magnetic ring, ensures stable linkage between the magnetic ring, the mounting base, and the impeller body. This guarantees that the magnetic ring's rotational force is transmitted to the impeller body, improving the overall operational stability and transmission efficiency of the guide wheel.

[0022] like Figures 1-5 As shown, a sand-resistant guide wheel includes: The impeller body 100 is integrally formed from wear-resistant alloy. A fixing seat 110 for supporting the impeller body 100 is welded to the bottom of the impeller body 100. An mounting part is provided at the bottom of the impeller body 100 for fixing the impeller body 100. The wear-resistant alloy is made of high-chromium cast iron. Mounting base 200, impeller body 100 is fixedly mounted on the bottom of mounting base 200, magnetic ring 300 is fixedly mounted in the inner cavity of mounting base 200, and contact part is provided on mounting base 200 to increase the contact area between mounting base 200 and magnetic ring 300. A locking element is fixedly installed at the bottom of the fixed base 110 to prevent the magnetic ring 300 from rotating independently; The cover plate 240 is fixedly installed on the outside of the mounting base 200. The outside of the cover plate 240 is provided with multiple edge portions 241. A groove 242 corresponding to the mounting part is provided between every two edge portions 241 for guiding the welding and fixing of the impeller body 100.

[0023] As a preferred example of this utility model, the mounting component provides fixed support for the impeller body 100, which is assembled on the top of the mounting base 200. The magnetic ring 300 enables the mounting base 200 and the impeller body 100 to rotate. The locking component fixes the magnetic ring 300 to the mounting base 200, preventing the magnetic ring 300 from rotating independently. The cover plate 240 on the outer side of the mounting base 200 forms a structural support through multiple outer edge portions 241. The grooves 242 between the edge portions 241 correspond to the mounting components of the impeller body 100, providing guidance when the impeller body 100 is welded and fixed, ensuring the accuracy of the welding position.

[0024] In the example of this application, the mounting component includes a mounting plate 130, which is fixedly connected to the bottom of the impeller body 100. The mounting base 110 has a guide groove 111 that matches the mounting plate 130. The mounting plate 130 passes through the guide groove 111 and extends into the groove 242. The shapes of the mounting plate 130, the guide groove 111 and the groove 242 are all arc-shaped.

[0025] As a preferred example of this utility model, the mounting piece 130 passes through the guide groove 111 and extends into the groove 242. Then, by welding, the mounting piece 130 is fixed to the fixing seat 110 and the cover plate 240. The groove 242 is designed to avoid positional displacement during welding, and the arc shape is used to fit the impeller body 100.

[0026] In the example of this application, the locking member includes a connecting rod 120, which is fixedly connected to the bottom of the fixing base 110. The magnetic ring 300 has a connecting hole 310 at its top, and the connecting rod 120 is located in the inner cavity of the connecting hole 310.

[0027] As a preferred example of this utility model, the connecting hole 310 at the top of the magnetic ring 300 matches the size of the connecting rod 120, and the connecting rod 120 is embedded in the inner cavity of the connecting hole 310 to form a limit, which can prevent the magnetic ring 300 from rotating independently.

[0028] In the example of this application, a support ring 220 is fixedly connected to the bottom of the inner cavity of the mounting base 200, and an annular groove 330 is opened at the bottom of the magnetic ring 300, with the support ring 220 fixedly disposed in the inner cavity of the annular groove 330.

[0029] As a preferred example of this utility model, the support ring 220 and the annular groove 330 at the bottom of the magnetic ring 300 form a fitting structure. After the support ring 220 is fully embedded in the inner cavity of the annular groove 330, it provides a bottom support point for the magnetic ring 300. The positioning function of the annular groove 330 restricts the axial movement of the magnetic ring 300 and prevents the magnetic ring 300 from moving axially during operation.

[0030] In the example of this application, a notch 243 is provided at one end of the groove 242.

[0031] As a preferred example of this utility model, during welding, the welding torch can be inserted into the groove 242 through the notch 243 to perform welding operations on the mounting piece 130. The notch 243 provides a channel for cleaning welding slag. Preferably, the notch 243 is located at the outer edge of the edge portion 241.

[0032] In the example of this application, the contact portion includes a first contact surface 210 and a second contact surface 320. The first contact surface 210 is disposed at the lower end of the inner sidewall of the mounting base 200, and the second contact surface 320 is disposed at the lower end of the sidewall of the magnetic ring 300. The first contact surface 210 and the second contact surface 320 are adapted to each other.

[0033] As a preferred example of this utility model, the first contact surface 210 and the second contact surface 320 are in a corresponding fit, which increases the contact area between the mounting base 200 and the magnetic ring 300, making the connection between the two tighter and able to evenly distribute the force generated by the magnetic ring 300 during operation to all parts of the contact surface.

[0034] In the example of this application, both the first contact surface 210 and the second contact surface 320 have rounded corners.

[0035] As a preferred example of this utility model, the rounded corner structure eliminates the sharp edges of the contact surface, avoiding damage to the contact surface caused by the collision of sharp edges during installation; the rounded corner structure can alleviate the problem of stress concentration and prevent fatigue damage such as deformation and cracking of the contact surface caused by long-term stress concentration.

[0036] In the example of this application, a mounting post 230 is fixedly connected to the middle of the inner cavity of the mounting base 200, and a magnetic ring 300 is fixedly connected to the outside of the mounting post 230.

[0037] As a preferred example of this utility model, the magnetic ring 300 is fixedly sleeved on the outside of the mounting post 230. The design of the center position of the mounting post 230 ensures that the magnetic ring 300 can be installed in the central area of ​​the mounting base 200, thus ensuring the coaxiality of the magnetic ring 300 and the impeller body 100.

[0038] In the example of this application, a through hole 231 is provided at the top center of the impeller body 100, the fixed seat 110, the mounting base 200 and the mounting column 230.

[0039] As a preferred example of this utility model, through holes 231 are provided at the top center of the impeller body 100, the fixed seat 110, the mounting base 200 and the mounting column 230. The through holes 231 provide space for subsequent cable laying, installation of the magnetic ring 300 drive component and other supporting operations.

[0040] In practical use, the arc-shaped mounting plate 130 at the top of the impeller body 100 passes through the arc-shaped guide groove 111 on the fixed seat 110, allowing the mounting plate 130 to extend into the arc-shaped groove 242 of the cover plate 240. The corresponding fit between the guide groove 111 and the groove 242 fixes the position of the mounting plate 130, preventing displacement during welding. During welding, the welding torch can be inserted into the groove 242 through the notch 243 at one end of the groove 242, directly welding the connection between the mounting plate 130 and the fixed seat 110, and between the mounting plate 130 and the cover plate 242. During operation, the magnetic ring 300 generates a rotational driving force. Because the magnetic ring 300 is engaged with the connecting rod 120 at the bottom of the impeller body 100 through the connecting hole 310, the magnetic ring 300... The magnetic ring 300 is fixedly sleeved on the outside of the mounting post 230 inside the mounting base 200. At the same time, its bottom annular groove 330 is fitted with the support ring 220 of the mounting base 200, and the second contact surface 320 of the side wall is in contact with the first contact surface 210 inside the mounting base 200. This allows the rotational force of the magnetic ring 300 to be transmitted to the mounting base 200, thereby driving the impeller body 100 fixed on the top of the mounting base 200 to rotate synchronously. The impeller body 100 passes through the guide groove 111 of the fixed seat 110 through the top mounting piece 130 and extends into the groove 242 of the cover plate 240. The cover plate 240 helps to limit the position of the impeller body 100, ensuring that the impeller body 100 rotates stably with the magnetic ring 300 and the mounting base 200.

[0041] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
