[0018] The following is combined with Figure 1-2 This application is described in further detail.

[0019] This application discloses a large-scale vertical pump testing device.

[0020] Reference Figure 1-2 The large vertical pump test apparatus includes a test water tank, which is made of concrete. The size and depth of the water tank are determined according to the dimensions of the large vertical pump 1. An installation platform 2 is installed on top of the test water tank. The installation platform 2 is made of steel and has sufficient strength and stability. Fixed supports 3 are installed on the top surface of the installation platform 2. At least two fixed supports 3 are provided. An installation plate 12 is fixedly connected to the pump body of the vertical pump 1. The fixed supports 3 are located on both sides of the installation plate 12. The installation plate 12 is fixed to the fixed supports 3 by bolts. The suction inlet of the vertical pump 1 is submerged in the test water tank.

[0021] A motor bracket 4 is provided on the top surface of the fixed support 3. The motor bracket 4 includes four legs 41 and a support plate 42. The bottom surface of the support plate 42 is fixedly connected to the top surface of the legs 41. The bottom surface of the legs 41 is fixed to the fixed support 3. The motor 11 of the vertical pump 1 is installed on the top surface of the support plate 42.

[0022] An X-shaped reinforcing rib 5 is provided between two adjacent support legs 41, and a horizontal reinforcing rib 6 is also provided between two adjacent support legs 41. Each X-shaped reinforcing rib 5 has a corresponding horizontal reinforcing rib 6 above and below it. A vertical reinforcing rib plate 7 is provided between the upper horizontal reinforcing rib 6 and the support plate 42, and multiple vertical reinforcing rib plates 7 are equidistantly arranged along the length of the horizontal reinforcing rib 6. By setting multiple sets of reinforcing ribs, the structural strength and supporting force of the motor bracket 4 are improved.

[0023] The discharge port of the vertical pump 1 is connected to a test pipeline 8. A pressure sensor 82 and a flow meter 83 are installed on the test pipeline 8. Both the pressure sensor 82 and the flow meter 83 are electrically connected to the backend control system and feed back the detected data to the control system. The pressure sensor 82 is used to detect the pressure within the test pipeline 8, and the flow meter 83 is used to detect the flow rate within the test pipeline 8. This enables high-precision measurement of the pump's performance parameters, providing strong support for pump performance evaluation and optimization.

[0024] The test pipeline 8 is made of stainless steel. The pipe diameter and wall thickness are determined according to the flow and pressure requirements of the pump. During installation, the sealing between the test pipeline 8 and the vertical pump 1 must be ensured.

[0025] A regulating valve 81 is installed on the test pipeline 8. The regulating valve 81 is used to regulate the flow rate of the test pipeline 8. The regulating valve 81 is located on the test pipeline 8 near the outlet of the test pipeline 8.

[0026] The computer control unit of the control system uses a high-performance industrial computer, and the electrical control cabinet is assembled using standard electrical components.

[0027] By installing a full-size large vertical pump 1 on the test water tank, the actual working conditions of the full-size large vertical pump 1 are realistically simulated, which improves the accuracy, reliability and reliability of the test results.

[0028] The implementation principle of a large vertical pump testing device according to an embodiment of this application is as follows:

[0029] The vertical pump 1 is installed on the mounting platform 2, and the motor 11 of the vertical pump 1 is installed on the support plate 42. The input end of the vertical pump 1 is connected to the output end of the motor 11 through a coupling. The pressure sensor 82, flow meter 83 and testing equipment are checked. After confirming that everything is correct, the vertical pump 1 is started. During the test, the pump's operating status is closely observed and various performance parameters are recorded. Through the analysis of the test data, it was found that the pump has a problem of low efficiency under certain operating conditions, which provides a basis for subsequent optimization design.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
