Description

Technical Field

[0001] This utility model relates to the field of magnetic pumps, and in particular to a base plate structure in a magnetic pump. Background Technology

[0002] As a highly efficient and energy-saving fluid transport device, the permanent magnet direct-drive pump uses a permanent magnet coupling for power transmission in its core component. During installation, the levelness and positional accuracy of the pump body directly affect the operational stability and service life of the equipment.

[0003] Traditional installation methods have many problems: existing base plate structures are mostly simple flat plate designs, lacking dedicated load-bearing and positioning structures, making it difficult to fine-tune the pump body after installation and affecting installation accuracy; the fixing holes are single and non-adjustable, unable to adapt to the needs of different installation environments, and lack effective anti-misinstallation design, which can easily lead to incorrect installation direction; existing base plate structures are insufficient in load-bearing capacity, and are prone to deformation after long-term use, affecting the operating accuracy of the pump body.

[0004] These problems not only increase installation difficulty but may also lead to adverse consequences such as increased pump body vibration and accelerated bearing wear. Especially in operating conditions where frequent pump body replacement or maintenance is required, the repeatability of traditional base plates is difficult to guarantee, seriously affecting the service life of the equipment and maintenance efficiency.

[0005] In addition, the lack of an effective guiding and positioning structure in the existing technology often leads to misalignment during installation, increasing the difficulty of operation for installers.

[0006] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this invention is to provide a base plate structure for a magnetic pump, which has the advantages of improving installation accuracy, facilitating position adjustment, enhancing structural stability, and preventing misaligned installation.

[0010] Furthermore, the positioning hole assembly includes a lateral positioning hole and a longitudinal positioning hole, the main structure of which is an elongated hole for easy adjustment of the connection position.

[0011] Furthermore, the limiting groove and the positioning block form a stepped structure, and the magnetic pump is limited and positioned on the limiting groove of the substrate through the stepped structure; the inner side of the guide block is provided with a guide slope, and the bottom end of the guide slope extends to the limiting groove.

[0012] Furthermore, the positioning protrusion is located in the middle of the top surface of the positioning block, and the two sets of pump body connection holes are respectively located on both sides of the positioning protrusion.

[0013] Furthermore, a set of symmetrically arranged positioning protrusions are used to cooperate with the positioning groove at the bottom of the magnetic pump for pre-installation.

[0014] In summary, this utility model has the following beneficial effects:

[0017] Figure 2 This is a bottom view of the base plate structure in the magnetic pump described in this utility model. Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with the illustrations and specific embodiments.

[0019] See Figure 1 and Figure 2 This application proposes a base plate structure for a magnetic pump, including a base plate 1, a positioning hole assembly 2 provided along the edge of the base plate 1, a limiting groove 3 provided on the base plate 1 inside the positioning hole assembly 2, a threaded hole 4 provided at the outer end of the limiting groove 3, a positioning block 5 provided at the inner end of the limiting groove 3, a guide block 6 provided on both sides along the length direction of the limiting groove 3, the inner end of the guide block 6 extending to the positioning block 5, and a positioning protrusion 7 for pre-installation with the bottom of the magnetic pump and a pump body connection hole 8 for fixed connection with the bottom of the magnetic pump on the positioning block 5.

[0020] The components are as follows: Base plate 1 refers to the metal plate structure supporting the pump body, specifically made of Q235 steel plate with a thickness of 8-12mm, serving as the load-bearing foundation of the overall structure. Positioning hole assembly 2 refers to the hole structure located on the edge of base plate 1, specifically using elongated holes arranged alternately horizontally and vertically, with the installation position adjusted by sliding bolts within these holes. Limiting groove 3 refers to the groove structure formed on the surface of base plate 1, specifically using a U-shaped groove with a width of 30-50mm, used to constrain the horizontal displacement of the pump body. Threaded hole 4 refers to the threaded hole located at the outer end of the limiting groove 3, specifically using an internal threaded hole of M10-M12 specifications, used to fix the outer end of the pump body by bolt tightening. Positioning block 5 refers to the boss structure located at the inner end of the limiting groove 3, specifically using a rectangular steel block with a height of 5-8mm, forming a stepped limiting structure with the limiting groove 3. Guide block 6 refers to the inclined structure located on both sides of the limiting groove 3, guiding the pump body to slide into the installation position along a predetermined path. The positioning protrusion 7 refers to the protruding structure set on the top of the positioning block 5, which forms a pre-positioning fit with the groove at the bottom of the pump body.

[0021] Specifically, the base plate 1, as the overall load-bearing component, has positioning hole assemblies 2 on its edges that allow for lateral and longitudinal adjustment of the installation position through elongated hole structures. When the pump body is placed into the limiting groove 3, the inclined surface of the guide block 6 guides the pump body to move along the groove direction until the positioning protrusion 7 is embedded in the groove at the bottom of the pump body to complete the pre-positioning. At this time, the outer end of the pump body is fixed through the threaded hole 4, and the inner end is connected to the positioning block 5 through the pump body connecting hole 8. The guide blocks 6 on both sides of the limiting groove 3 extend to the positioning block 5, forming a continuous guide path to ensure that the pump body does not deviate horizontally during movement. The combination of the stepped limiting groove 3 and the positioning block 5 restricts the displacement of the pump body in the vertical direction, while the threaded hole 4 and the pump body connecting hole 8 form a double fixing point at both the inner and outer ends.

[0022] Compared to existing technologies, traditional base plates with planar structures lack positioning constraints. This application addresses this by forming a three-dimensional constraint system through the limiting groove 3 and the guide block 6. Existing technologies rely on a single fixed hole position; this application's positioning hole assembly 2 achieves adjustable installation position through an elongated hole structure. Existing installation processes are prone to directional deviations; this application's positioning protrusion 7 and guide slope complete directional correction during the contact stage. Traditional structures achieve single-point fixation only through bolts; this application achieves multi-point fixation through the cooperation of inner and outer threaded holes 4 with the pump body connection hole 8.

[0023] Through the above technical solutions, this application effectively improves the installation and positioning accuracy of the magnetic pump. The installation deviation is controlled within 0.5mm by the cooperation of the guide block 6 and the limiting groove 3. The adjustable design of the positioning hole assembly 2 allows the base plate to adapt to different mounting surfaces, with an adjustment range of ±10mm. The pre-fitting structure between the positioning protrusion 7 and the pump body groove eliminates the risk of incorrect installation direction, and the guide slope allows for automatic correction during installation without manual alignment.

[0024] Example 1

[0025] This application further proposes that the positioning hole assembly 2 includes a transverse positioning hole 21 and a longitudinal positioning hole 22, the main structure of which is an elongated hole for easy adjustment of the connection position.

[0026] The transverse positioning hole 21 refers to a positioning structure extending horizontally, which can be implemented using an elongated oval hole shape. Its length direction is parallel to the transverse axis of the magnetic pump mounting plane, providing freedom of position adjustment in the horizontal direction. The longitudinal positioning hole 22 refers to a positioning structure extending vertically, which can also be implemented using an elongated oval hole shape. Its length direction is parallel to the longitudinal axis of the magnetic pump mounting plane, providing freedom of position adjustment in the vertical direction. The elongated oval hole refers to a structure with semicircular ends and a rectangular groove in the middle. It can be achieved through machining or stamping processes. Its extension in the length direction allows the connecting bolts to move within the hole, thus providing physical space for installation position adjustment.

[0027] Specifically, the transverse positioning hole 21 and the longitudinal positioning hole 22 are arranged along the horizontal and vertical directions, respectively, forming a cross positioning reference. The elongated characteristic of the oblong hole allows the connecting bolt to move along the horizontal axis within the transverse positioning hole 21 and along the vertical axis within the longitudinal positioning hole 22. During installation, the positional offset of the magnetic pump in the transverse or longitudinal direction is compensated by adjusting the position of the bolt within the oblong hole. The cross arrangement of the transverse and longitudinal positioning holes 22 ensures that the positioning reference in at least one direction remains stable during adjustment, preventing the overall installation reference from failing due to bidirectional adjustment.

[0028] Compared to existing technologies, traditional base plates use circular fixing holes, the diameter of which matches the bolt diameter, resulting in strict limitations on installation position. This solution replaces the circular holes with elongated holes, retaining the positioning function while increasing the adjustability in the length direction. This allows the same base plate to adapt to different mounting base hole spacing deviations or equipment layout differences, without the need for reprocessing or replacing the base plate.

[0029] Through the above technical solution, this application realizes the ability to independently adjust the installation position of the magnetic pump in the horizontal and vertical directions, solves the problem of insufficient installation adaptability caused by the single fixed hole position, enables the base plate to be compatible with the position tolerance requirements of different installation environments, and maintains the stability of the installation reference after adjustment through cross positioning.

[0030] Example 2

[0031] This application further proposes that the limiting groove 3 and the positioning block 5 form a stepped structure, and the magnetic pump is limited and set on the limiting groove 3 of the substrate 1 through the stepped structure; the inner side of the guide block 6 is provided with a guide slope, and the bottom end of the guide slope extends to the limiting groove 3.

[0032] Among them, the stepped structure refers to the vertical drop structure formed by the bottom surface of the limiting groove 3 and the top surface of the positioning block 5. Specifically, it can be achieved by milling to form step surfaces of different heights, and the vertical drop of the step surfaces forms a lateral displacement constraint.

[0033] The guide slope refers to the inclined guide surface set inside the guide block 6. Specifically, it can be machined with a slope angle of 30°-60°. The slope contacts the side wall of the pump body to generate a sliding guide effect.

[0034] Specifically, during the installation of the magnetic pump, the bottom of the pump body first contacts the guide ramp, which guides the pump body to move along a predetermined path to the limiting groove 3 area. As the pump body continues to press down, the top surface of the positioning block 5 contacts the bottom of the pump body to form longitudinal support, and the side wall of the limiting groove 3 contacts the side of the pump body to form lateral constraint, thereby achieving three-dimensional spatial positioning. The design of the bottom end of the guide ramp extending to the edge of the limiting groove 3 allows the pump body to naturally slide into the bottom of the limiting groove 3 after contacting the ramp, avoiding positional displacement during installation.

[0035] Through the above technical solution, this application achieves one-step positioning during the installation of the magnetic pump, eliminating positioning errors caused by manual adjustment. The cooperation between the guide ramp and the stepped structure allows the pump body to automatically slide into the correct installation position under gravity, preventing wear of the sealing surface due to installation angle deviation. The multiple limiting surfaces formed by the stepped structure can disperse the pressure generated by the weight of the pump body, avoiding local deformation of the base plate 1 from affecting the positioning accuracy.

[0036] Example 3

[0037] This application further proposes that the positioning protrusion 7 is located in the middle of the top surface of the positioning block 5, and the two sets of pump body connection holes 8 are respectively located on both sides of the positioning protrusion 7.

[0038] The positioning protrusion 7 refers to the raised structure located in the middle of the top surface of the positioning block 5. It can be implemented using a cylindrical or square column-shaped boss, and its height and shape match the positioning groove at the bottom of the magnetic pump, providing a centrally symmetrical positioning reference during the initial installation. The pump body connection hole 8 refers to the threaded holes 4 distributed on both sides of the positioning protrusion 7. It can be implemented using a symmetrically distributed bolt hole structure, forming a stable multi-point fixing system through symmetrical fastening forces on both sides.

[0039] Specifically, during the installation of the magnetic pump, the positioning protrusion 7 engages with the positioning groove on the bottom of the pump body, forming a centrally symmetrical constraint relationship to ensure that the pump body axis remains perpendicular to the base plate reference plane. Two sets of pump body connection holes 8 are located on either side of the positioning protrusion 7. When bolts are tightened through the connection holes, the symmetrical tension on both sides causes the bottom surface of the pump body to evenly adhere to the surface of the positioning block 5, avoiding localized stress concentration caused by unilateral force. The centrally positioned positioning protrusion 7 serves as the core positioning reference, forming a dual constraint mechanism with the connection holes on both sides. This prevents incorrect installation direction and distributes the tightening load through the symmetrically distributed connection holes, thereby eliminating vibration or displacement caused by uneven force.

[0040] Through the above technical solution, this application effectively reduces the risk of misinstallation during the installation of the magnetic pump. At the same time, the symmetrically distributed connecting holes achieve balanced force distribution, avoiding pump body displacement or loosening of connecting parts due to local stress concentration, thereby ensuring the long-term stability of the equipment.

[0041] Example 4

[0042] This application further proposes that a set of symmetrically arranged positioning protrusions 7 are used to cooperate with the positioning groove at the bottom of the magnetic pump for pre-installation.

[0043] The positioning protrusion 7 refers to the raised structure on the top surface of the positioning block 5, which can be implemented as a cylindrical or rectangular boss, and its shape complements the positioning groove at the bottom of the magnetic pump. Symmetrical arrangement means that the two positioning protrusions 7 are mirror-distributed along the central axis of the positioning block 5, which can be achieved by an equally spaced symmetrical layout, using geometric symmetry to constrain the installation direction. Pre-installation fit refers to the initial positioning achieved through the interlocking relationship between the protrusion and the groove, which can be achieved by a clearance fit or a transition fit, completing positional correction before tightening.

[0044] During the pre-installation stage, precise positioning is achieved through the forced matching of protrusions and grooves, reducing axial offset during subsequent fastening operations and ensuring the coaxiality requirements of the pump body and base plate 1. The dual-point support structure formed by symmetrical protrusions enhances installation stability and avoids vibration transmission problems that may be caused by single-point positioning.
