[0002] A pump test bench is a device used to test and evaluate pump performance and operating conditions. It provides an environment that simulates real-world operating conditions, allowing for accurate evaluation of pump performance by controlling fluid parameters and measuring relevant parameters. The design and construction of a pump test bench allow users to conduct comprehensive testing of pumps under different operating conditions, including the measurement and analysis of performance indicators such as flow rate, head, power, efficiency, and pressure pulsation.

[0003] During the test, the pump connection plate assembly needs to be connected to the test bench for loading. However, the pump connection plate assembly is quite heavy, and it is difficult for one operator to lift the pump connection plate assembly while docking and fixing it to the test bench. Therefore, this process often requires the cooperation of multiple operators.

[0004] Therefore, to address the above problems, a rotary feeding mechanism for a pump test bench can be designed, enabling a single person to feed the pump connection plate assembly of the pump test bench. Utility Model Content

The drive motor 2 can drive the rotary spindle 4 to rotate through the spindle box 3, thereby testing the pump connection plate assembly 908. The servo electric cylinder 5 can move the fixing plate 6 to adjust its position. In this process, only the process of fixing the pump is relatively labor-intensive, while the other processes consume less manpower. Furthermore, the fixing and docking processes are separated, so that a single person can easily load the experimental platform pump.

[0023] Please see Figure 1 In this embodiment, a first worktable 101 is provided at the bottom of the spindle box 3. The first worktable 101 is fixedly connected to the spindle box 3 and the servo cylinder 5. A first guide rail 102 is provided on one side of the first worktable 101.

[0025] Please see Figures 1-3In this embodiment, a slewing bearing 801 is provided between the sliding table 8 and the rotary table 9. A connecting platform 104 is provided at the bottom of the sliding table 8, and a buffer seat 106 is provided above the connecting platform 104.

[0026] Please see Figure 4 In this embodiment, a hydraulic cylinder 701 is provided on the inner side of the fixing plate 6. A clamping block 7 is provided on the movable end of the hydraulic cylinder 701. A connecting block 702 is provided in the middle of the clamping block 7. The connecting block 702 is rotatably connected to the clamping block 7. A pressing block 703 is provided on the end of the clamping block 7 away from the hydraulic cylinder 701. After docking is completed, the hydraulic cylinder 701 extends to push the clamping block 7 and the connecting block 702 to rotate, so that the pressing block 703 contacts the adapter plate 903 and clamps and fixes the adapter plate 903. At the same time, the cylinder 601 and the connecting hole 906 are engaged with each other to prevent the adapter plate 903 from rotating with the connector 905.

[0028] During loading, the pump connecting plate assembly 908 is fixed to the adapter plate 903. Then, the rotary table 9 is rotated so that the connector 905 faces the direction of the rotating spindle 4. The sliding table 8 is then pushed so that the pump connecting plate assembly 908 slides with the sliding table 8 until the adapter plate 903 contacts the fixed plate 6. At this time, the second quick-connect connector 907 contacts the first quick-connect connector 603 and automatically connects. Before the adapter plate 903 contacts the fixed plate 6, the hydraulic cylinder 701 is in its shortest state so that the clamping block 7 is kept open. After docking, the hydraulic cylinder 701 extends so that the clamping block 7 rotates and the pressure block 703 contacts the adapter plate 903 to clamp and fix the adapter plate 903. The cylinder 601 and the connecting hole 906 are engaged to prevent the adapter plate 903 from rotating. Then, the drive motor 2 can be started to drive the rotating spindle 4 to rotate using the spindle box 3 to test the pump connecting plate assembly 908.
