Description

A pump body mounting structure for a centrifugal pump Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, and more specifically, to a pump body mounting structure for a centrifugal pump. Background Technology

[0002] Centrifugal pumps are core fluid transport equipment in industrial fields (such as chemical, petroleum, metallurgy, and water treatment). The reliability of their installation structure directly affects the equipment's operational stability, ease of maintenance, and service life.

[0003] There are many existing technologies for the installation structure of centrifugal pump bodies, such as:

[0004] Chinese Patent (Application No.: CN202420925720.8) discloses a pump body mounting structure for a chemical centrifugal pump. Addressing the issues of existing technologies that use clamping rods to engage connecting blocks to fix the base plate to the mounting plate, but where the rectangular connecting blocks are inconvenient to position during insertion, and the transmission plate being located within the connecting plate necessitates special manufacturing of the connecting plate, increasing installation costs, this invention proposes the following solution: It includes a centrifugal pump, a base, and a mounting plate. The base is fixed to the bottom of the centrifugal pump and positioned on top of the mounting plate. In this invention, the base is fixed to the mounting plate through the combined use of clamping plates and the mounting plate. Simultaneously, fixing strips are also fixed to the mounting plate, facilitating positioning during installation. This not only improves installation efficiency but also eliminates the need for special components, reducing installation costs.

[0005] Traditional centrifugal pumps typically rely on flange connections and bolt fixing to rigidly connect the pump body to the base or equipment bracket. Before installation, holes need to be drilled at the connection points between the pump body and the base, and then the pump body is fixed one by one with traditional bolts. This is time-consuming and labor-intensive, reducing the efficiency of pump body installation. During the installation process, the installation position of the pump body needs to be adjusted manually and repeatedly to ensure the accuracy of the installation position. This process is time-consuming and has low precision, making the pump body installation less convenient. Summary of the Invention

[0006] This utility model addresses the technical problems existing in the prior art by providing a pump body installation structure for centrifugal pumps, solving the problems that the traditional centrifugal pump body installation process is relatively cumbersome, resulting in low installation and disassembly efficiency, and insufficient installation accuracy and fixing stability.

[0007] To achieve the above objectives, this utility model provides a pump body mounting structure for a centrifugal pump, including a centrifugal pump body. A mounting assembly is provided at the bottom of the centrifugal pump body. The mounting assembly includes a base plate, with symmetrically arranged sliding grooves at both ends inside the base plate. Sliding columns are slidably connected inside the sliding grooves, and a protruding plate is fixedly connected to one end of each sliding column. A mounting platform is provided at the bottom of the mounting assembly. The distance between the two protruding plates is adjusted by the synchronous sliding of the two sliding columns within the sliding grooves, allowing the protruding plates to clamp the mounting platform from the front and back.

[0008] The beneficial effects of this utility model are:

[0009] 1. When installing the pump body, the distance between the two convex plates is adjusted by the synchronous relative or opposite sliding of the two sliding columns in the installation assembly. The two convex plates are placed on the front and rear sides of the installation platform respectively, which can quickly and accurately align the centrifugal pump body with the front and rear installation position of the installation platform, thereby improving the installation accuracy of the pump body.

[0010] 2. After the pump body is installed, the mounting platform is clamped and fixed by the convex plate in the mounting assembly. There is no need to use external tools to drill holes in the centrifugal pump body and the mounting platform. This protects the integrity of the pump body and the mounting platform, reduces processing steps and potential defects, avoids human operation errors, improves the accuracy of pump body installation, and improves installation and disassembly efficiency. In addition, the mounting assembly is flexible and can be compatible with various types of mounting platforms, improving the versatility of the mounting assembly.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Preferably, the sliding column is internally threaded with a bidirectional lead screw, which is symmetrically rotatably connected to both ends inside the base plate. A first gear is fixedly connected to the outside of the bidirectional lead screw, and a second gear is meshed with the outside of the first gear. A rotating rod is fixedly connected to the top of the second gear, and a fixed cylinder is rotatably connected to the outside of the rotating rod. The fixed cylinder is fixedly connected to the top of the base plate.

[0013] The advantage of adopting the above-mentioned further solution is that the sliding columns and protruding plates on both sides can be adjusted simultaneously by simply rotating the rotating rod with one hand, which effectively improves the installation efficiency compared to the traditional method of adjusting one bolt at a time.

[0014] Preferably, a baffle is fixedly connected to one end of the slide groove, and a limiting plate is fixedly connected to one end of the sliding column. The limiting plate slides inside the slide groove, and the baffle limits the sliding range of the limiting plate.

[0015] The beneficial effect of adopting the above-mentioned further solution is to ensure that the sliding column always moves within the preset stroke, avoid installation failure caused by excessive adjustment, and ensure the structural integrity and stability of the installation components.

[0016] Preferably, the upper end of the rotating rod has several through holes in an annular design, and a pin is slidably connected inside the through holes. The lower end of the pin passes through the through holes and engages with a slot inside the fixed cylinder.

[0017] The beneficial effect of adopting the above-mentioned further solution is that it effectively prevents the relative rotation between the rotating rod and the fixed cylinder, avoids the failure of the clamping force due to the uncontrolled rotation of the bidirectional screw, and ensures the stable clamping of the convex plate on the installation platform.

[0018] Preferably, a limiting component is provided on one side of the convex plate. The limiting component includes a clamping plate, a bolt is rotatably connected to the top of the clamping plate, a connecting plate is fixedly connected to one side of the convex plate, a threaded cylinder is fixedly connected inside the connecting plate, the outer side of the bolt is threadedly connected to the inner side of the threaded cylinder, a limiting rod is fixedly connected to the top of the clamping plate, the limiting rod slides up and down inside the connecting plate, and an adsorption pad is fixedly connected to one end of the top of the clamping plate.

[0019] The beneficial effect of adopting the above-mentioned further solution is that it enables vertical clamping and fixing of installation platforms of different thicknesses, and, together with the convex plate, front-back clamping and fixing of the installation platform, achieves three-dimensional limiting and fixing of the installation position of the centrifugal pump body, increases the stability of pump body installation, and helps reduce the risk of displacement after pump body installation.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] Through the linkage design of the bidirectional lead screw, the first gear, and the second gear, rotating the rotating rod synchronously drives the sliding columns on both sides to slide relative to or away from each other in the sliding groove. This allows for quick adjustment of the distance between the two convex plates, achieving precise alignment of the centrifugal pump body with the mounting platform, avoiding human error, and enabling front and rear clamping and fixing of mounting platforms of different widths. This increases the applicability of pump installation. Then, by adjusting the upper and lower positions of the clamping plates in the limiting assembly, the mounting platform is pressed and clamped, achieving rigid upper and lower clamping and fixing of mounting platforms of different thicknesses. This structure provides three-dimensional limiting and fixing of the centrifugal pump body's installation position, increasing the stability of pump installation. Compared with traditional bolt-mounted installation, this improves pump installation efficiency and ease of operation. Attached Figure Description

[0031] 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.

[0032] Please refer to Figures 1-4. This embodiment provides a pump body mounting structure for a centrifugal pump, including a centrifugal pump body 1. Considering that the traditional centrifugal pump body installation process is relatively cumbersome, resulting in low installation and disassembly efficiency and insufficient installation accuracy and fixing stability, an installation component 2 is provided at the bottom of the centrifugal pump body 1. The installation component 2 includes a base plate 21. Both ends of the base plate 21 are symmetrically provided with sliding grooves 22. Sliding columns 23 are slidably connected inside the sliding grooves 22. A protruding plate 211 is fixedly connected to one end of the bottom of the sliding column 23. An installation platform 4 is provided at the bottom of the installation component 2. The distance between the two protruding plates 211 is adjusted by the two sliding columns 23 sliding synchronously in the sliding grooves 22 relative to each other or back to back, so as to realize the front and rear clamping of the protruding plate 211 on the installation platform 4.

[0033] In summary, the improvement of this embodiment lies in:

[0034] The centrifugal pump body 1 is fixed on top of the mounting assembly 2. The mounting assembly 2 is connected to the mounting platform 4 by the clamping of the convex plate 211, which enables the pump body to be quickly positioned. During the process, the two sliding columns 23 in the mounting assembly 2 slide synchronously relative to each other or in opposite directions to adjust the distance between the two convex plates 211, so as to achieve precise alignment of the centrifugal pump body 1 and the mounting platform 4. The clamping and fixing method eliminates the need for drilling the centrifugal pump body 1 and the mounting platform 4 with external tools, protects the integrity of the pump body and the mounting platform 4, reduces processing steps and potential defects, avoids human operation errors, improves the accuracy of pump body installation and improves installation and disassembly efficiency, is compatible with various types of mounting platforms 4, and improves the versatility of the mounting assembly 2.

[0035] Based on the above, other structures also need to be disclosed in detail, such as:

[0036] To increase the ease of pump installation and improve installation efficiency, a double-acting screw 24 is threaded inside the sliding column 23. The double-acting screw 24 is symmetrically rotatably connected to both ends inside the base plate 21. A first gear 25 is fixedly connected to the outside of the double-acting screw 24. A second gear 26 is meshed with the outside of the first gear 25. A rotating rod 27 is fixedly connected to the top of the second gear 26. A fixed cylinder 28 is rotatably connected to the outside of the rotating rod 27. The fixed cylinder 28 is fixedly connected to the top of the base plate 21. When installing the centrifugal pump body 1, first place the centrifugal pump body 1 and the mounting assembly 2 on top of the mounting platform 4. At this time, the distance between the two protruding plates 211 is at its maximum value. Then, by rotating the rotating rod 27, the second gear 26 is driven to rotate. The first gear 25 and the second gear 26 mesh, thereby driving the second gear 26 to rotate and causing the bidirectional lead screw 24 to rotate synchronously. The rotational motion of the rotating rod 27 is converted into the linear motion of the bidirectional lead screw 24, causing the sliding columns 23 on both sides to move relative to each other. The distance between the two protruding plates 211 is quickly adjusted to adapt to the mounting platform 4 of different sizes. Initial positioning can be completed without tools. At the same time, since the protruding plates 211 move to the same position, the front and rear positions of the centrifugal pump body 1 and the mounting platform 4 are accurately aligned, avoiding human operation errors. This process only requires one hand to rotate the rotating rod 27 to synchronously adjust the sliding columns 23 on both sides and the protruding plates 211. Compared with the traditional adjustment of each bolt one by one, the installation efficiency is effectively improved.

[0037] To prevent the sliding column 23 from sliding out of the groove 22 and separating from the base plate 21, a baffle 29 is fixedly connected to one end of the groove 22, and a limiting plate 210 is fixedly connected to one end of the sliding column 23. The limiting plate 210 slides inside the groove 22, and the baffle 29 limits the sliding range of the limiting plate 210 to ensure that the sliding column 23 always moves within the preset stroke, avoiding installation failure due to excessive adjustment, and ensuring the structural integrity and stability of the installation component 2.

[0038] To improve the stability of the pump body installation and prevent accidental rotation of the rotating rod 27, which would affect the fixing effect of the mounting component 2, several through holes 212 are designed in an annular shape at the upper end of the rotating rod 27. A pin 213 is slidably connected inside the through holes 212, and the lower end of the pin 213 passes through the through holes 212 and engages with a slot inside the fixed cylinder 28. Under the vibration of the centrifugal pump or the action of external forces, the engagement of the pin 213 effectively prevents relative rotation between the rotating rod 27 and the fixed cylinder 28, avoiding the failure of the clamping force due to uncontrolled rotation of the bidirectional lead screw 24, ensuring the stable clamping of the convex plate 211 on the mounting platform 4. Furthermore, the "unlocking adjustment - locking fixation" process of the rotating rod 27 can be easily achieved by inserting and removing the pin 213, without the need for additional tools, significantly shortening the installation and debugging time.

[0039] Furthermore, a limiting component 3 is provided on one side of the convex plate 211. The limiting component 3 includes a clamping plate 31. A bolt 32 is rotatably connected to the top of the clamping plate 31. A connecting plate 33 is fixedly connected to one side of the convex plate 211. A threaded cylinder 34 is fixedly connected inside the connecting plate 33. The outer side of the bolt 32 is threadedly connected to the inner side of the threaded cylinder 34. A limiting rod 35 is fixedly connected to the top of the clamping plate 31. The limiting rod 35 slides up and down inside the connecting plate 33. An adsorption pad 36 is fixedly connected to one end of the top of the clamping plate 31. By rotating the bolt 32, the clamping plate 31 is driven to move up and down, pressing the mounting platform 4, thereby clamping and fixing the mounting platform 4 of different thicknesses in the vertical direction. In conjunction with the convex plate 211, the mounting platform 4 is clamped and fixed in the front and rear direction, thereby achieving three-dimensional limiting and fixing of the installation position of the centrifugal pump body 1, increasing the stability of the pump body installation, and helping to reduce the risk of displacement after the pump body is installed. During the process, the limiting rod 35 provides vertical guidance for the horizontal movement of the clamping plate 31, preventing the clamping plate 31 from tilting due to the lateral force during threaded transmission, ensuring that the clamping surface is completely in contact with the mounting platform 4, and improving clamping stability. The adsorption pad 36 adsorbs the bottom of the mounting platform 4, and the adsorption pad 36 is a rubber pad or elastic component, which can form a buffer layer between the clamping plate 31 and the mounting platform 4, absorbing the vibration energy of the centrifugal pump during operation, reducing the loosening of the connection or wear of the components caused by rigid collision, and extending the structural life.

[0040] In summary, the working principle of this solution is as follows:

[0041] First, place the centrifugal pump body 1 and mounting assembly 2 on top of the mounting platform 4. At this point, the distance between the two protruding plates 211 is at its maximum. Then, drive the second gear 26 to rotate by rotating the rotating rod 27. The outer tooth grooves of the first gear 25 and the second gear 26 mesh with the rack, thereby driving the second gear 26 to rotate and causing the bidirectional lead screw 24 to rotate synchronously. This converts the rotational motion of the rotating rod 27 into the linear motion of the bidirectional lead screw 24, causing the sliding columns 23 on both sides to move relative to each other. This allows for quick adjustment of the distance between the two protruding plates 211 to fit different sizes of mounting platforms 4. Initial positioning can be completed without tools. This process only requires one hand to rotate the rotating rod 27 to synchronously adjust the sliding columns 23 on both sides and the protruding plates 211. Compared with the traditional method of adjusting one bolt at a time, the installation efficiency is effectively improved. After determining the position of the protruding plates 211, pass the lower end of the pin 213 through the through hole 212 and engage it in the slot inside the fixed cylinder 28. This effectively prevents relative rotation between the rotating rod 27 and the fixed cylinder 28, avoids the bidirectional screw 24 from losing control of rotation and causing clamping force failure, and ensures the stable clamping of the mounting platform 4 by the convex plate 211. Then, the clamping plate 31 is driven to move up and down by rotating the bolt 32 to press the mounting platform 4, thereby achieving vertical clamping and fixing of mounting platforms 4 of different thicknesses. In conjunction with the clamping and fixing of the mounting platform 4 in the front and back directions by the convex plate 211, the installation position of the centrifugal pump body 1 is three-dimensionally limited and fixed, increasing the stability of the pump body installation and helping to reduce the risk of displacement after the pump body is installed. At this time, the adsorption pad 36 adsorbs the bottom of the mounting platform 4. The adsorption pad 36 is a rubber pad or elastic component, which can form a buffer layer between the clamping plate 31 and the mounting platform 4 to absorb the vibration energy of the centrifugal pump during operation, reduce the loosening of the connection or wear of the components caused by rigid collision, and extend the service life of the structure.
