[0028] The principles and features of this utility model are described below with reference to all the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] This utility model discloses a pump body inlet ring bracket for a dynamic balancing machine.

[0030] Reference Figures 1 to 5 As shown, a pump body inlet ring bracket for a dynamic balancing machine includes a base 1, a connecting plate 3 at the bottom of the base 1, which is mounted on the dynamic balancing machine 9. A fixing plate 2 is provided at the top of the base 1. The base 1 is used to fix the fixing plate 2, ensuring that the fixing plate 2 is located at the horizontal center position of the dynamic balancing machine 9.

[0031] A plurality of support rods 4 are provided on the fixing plate 2, which is used to fix the support rods 4. The plurality of support rods 4 are arranged sequentially along the length of the fixing plate 2, and a pump body inlet ring support 5 is provided at the end of the support rod 4 away from the fixing plate 2. The pump body inlet ring support 5 is arranged in an upward arc shape. The plurality of pump body inlet ring supports 5 are arranged coaxially. The pump body inlet ring support 5 is detachably connected to the support rod 4. In this embodiment, six support rods 4 are selected, so there are six pump body inlet ring supports 5. The pump body inlet ring supports 5 are used to fix the pump body inlet ring 71 and to support the pump body inlet ring 71, the impeller 7, and the shaft 8.

[0032] The support rod 4 passes through the fixed plate 2, and a height adjusting nut 41 is threaded onto the support rod 4. The height adjusting nut 41 is positioned above the fixed plate 2. The height adjusting nut 41 is used to adjust the height of the pump body inlet ring support 5 so that the center of the pump body inlet ring 71 is concentric with the shaft center.

[0033] A washer 42 is fitted onto the support rod 4. The washer 42 is placed between the height adjusting nut 41 and the fixing plate 2, and the washer 42 abuts against the height adjusting nut 41 and the fixing plate 2 respectively. The washer 42 ensures that the height adjusting nut 41 is subjected to uniform force at the sliding groove 21 of the fixing plate 2.

[0034] The fixed plate 2 has grooves 21 distributed along its length, penetrating the fixed plate 2. Support rods 4 are placed within the grooves 21. The widths of the height adjusting nut 41 and the washer 42 are both greater than the width of the grooves 21. The grooves 21 allow for arbitrary adjustment of the position of the support rods 4 to accommodate the axial distance of the pump body inlet ring 71 for different pump models. The shape and size of the washer 42 are larger than those of the height adjusting nut 41.

[0035] Positioning guard plates 6 are provided on both sides of the base 1 to facilitate the positioning of the rotor assembly.

[0036] Reference Figures 1 to 5 As shown, the method of using a pump body inlet ring bracket for a dynamic balancing machine is as follows: First, assemble the rotor assembly components such as the original shaft 8, impeller 7, and pump body inlet ring 71. Then, install the pump body inlet ring bracket on the dynamic balancing machine 9 through the connecting plate 3. Adjust the number, height, and position of the support rod 4 and pump body inlet ring support 5 through the sliding groove 21 and height adjusting nut to adapt to pump body inlet ring 71 of different specifications. Place the rotor assembly and pump body inlet ring 71 on the dynamic balancing machine 9 and fix them through the connecting coupling. Fix the pump body inlet ring 71 on the pump body inlet ring support 5. After the installation and positioning are stable, start the dynamic balancing machine 9 to complete the dynamic balancing process of the rotor assembly.

[0037] Material selection in the manufacturing process: High-strength steel is used for the base 1, fixing plate 2, and connecting plate 3, while wear-resistant alloy is used for the pump body inlet ring support 5. Machining steps: CNC machining of the threaded structure on the slide groove 21 and support rod 4 → Assembly of components → Calibration of the horizontal center position.

[0038] This application reduces process steps and tooling usage, optimizes the process flow, reduces labor time, is reliable, simple and convenient to operate, improves operating efficiency and dynamic balancing accuracy, and thus extends the service life of the pump body. This application is easy to operate, requiring no assembly or disassembly of the process shaft; dynamic balancing is performed directly using the original shaft 8, reducing process steps. This application is cost-effective, saving approximately 115 minutes per unit (direct cost of RMB 119.8 per unit), and reducing process shaft design and processing costs (saving RMB 10,000-40,000 per model). This application improves precision, enhances dynamic balancing accuracy, effectively reduces pump body vibration, and extends pump service life; this application is highly versatile, with low bracket manufacturing cost (approximately RMB 878 per set), and two specifications cover all pump types, making it easy to promote.

[0039] The implementation principle of the pump body inlet ring bracket for a dynamic balancing machine according to this utility model embodiment is as follows:

[0040] Reference Figures 1 to 5 As shown, this application is used for dynamic balancing testing of rotor assemblies, and is specifically applicable to the optimization of dynamic balancing processes during pump body assembly.

[0041] The core improvement of this application lies in providing a dedicated bracket that enables the rotor assembly to undergo dynamic balancing testing directly after assembly, thus avoiding the use of process shafts.

[0042] The installation process involves fixing the bracket to the dynamic balancing machine 9 using the connecting plate 3, adjusting the height of the pump body inlet ring support 5 to concentricity using the height adjusting nut 41, fixing the rotor assembly, and then starting the test. No additional tools are required.

[0043] The design of the groove 21 allows for fine adjustment of the axial distance (to adapt to different pump types), and the gasket 42 ensures uniform force distribution and prevents loosening.

[0044] This application enables the rotor assembly to undergo dynamic balancing testing directly after assembly through a component structure (pump body inlet ring support 5, height adjustment nut 41, etc.), avoiding the use of process shafts. This application simplifies processes, reduces costs (saving 115 minutes / unit of labor), improves dynamic balancing accuracy, and extends pump service life, making it suitable for various pump body manufacturing scenarios.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
