[0002] Water pumps, as machines for transporting or pressurizing liquids, are widely used in industry, agriculture, municipal engineering, environmental protection, and other fields. Traditional water pumps have shaft seals, which pose a risk of leakage over time. Magnetic drive pumps, on the other hand, are shaft seal-free, offering a completely sealed, leak-free, and corrosion-resistant design. Currently available magnetic drive pump testing devices have relatively simple installation methods, only considering horizontal or normal installation scenarios, resulting in incomplete test results.

The device has a simple structure and is easy to operate, but it results in the installation direction being unable to be changed and the types of situations that can be tested are relatively limited.

[0004] A search revealed that patent application number CN2023202450002 provides a magnetic pump testing system. By using assembly components, the magnetic pump can be quickly moved closer to or away from the drive module, enabling rapid docking and disassembly of the magnetic pump and improving the testing efficiency. However, it still has the disadvantage of a fixed installation angle, making it impossible to test the reliability of the magnetic pump.

The second side of the pump outlet pipe 13 is fixed by a second collar 908 and then connected to the pump outlet 9011 on the magnetic pump 9012.

[0032] Both the pump inlet pipe 6 and the pump outlet pipe 13 are flexible metal hoses. The collar 908 is a metal ring with a notch, which allows it to be fitted onto the pump inlet pipe 6 and the pump outlet pipe 13 for fixation.

[0033] A pressure sensor A7 and a flow meter A8 are installed on the pump inlet pipe 6; a flow meter B11 and a pressure sensor B12 are installed on the pump outlet pipe 13. Pressure sensor A7, flow meter A8, flow meter B11 and pressure sensor B12 are all connected to a computer 10 for data processing and signal transmission.

[0034] The second embodiment of this utility model: like Figures 1-2 As shown in the figure, this embodiment of a magnetic pump reliability testing device includes a water tank 1 comprising a water tank support 2 and a water injection pipe 16. Before the experiment begins, experimental water is injected into the water tank 1 through the water injection pipe 16 until the experimental requirements are met. The water tank support 2 serves to support the water tank 1.

[0035] The inlet and outlet water pipelines include an outlet pipe 3, a flange 4, an outlet valve 5, a pump inlet pipe 6, a pump outlet pipe 13, a return valve 14, and a return pipe 15. The outlet pipe 3 is connected to the outlet valve 5 via the flange 4, and its diameter is adjusted to accommodate the test magnetic pump.

The magnetic pump 9012 is mounted on the rotating bracket 903 via the rotating shaft 909 and the set screw 904, allowing the magnetic pump 9012 to rotate around the rotating shaft 909 in a vertical plane. When the magnetic pump 9012 rotates to a predetermined test angle, the fixing screw 902 is inserted into the magnetic pump 9012 through the rotating groove B907 and tightened, using friction to fix the magnetic pump 9012. Then, the magnetic pump 9012 is rotated in the rotating groove A906. The connecting rod 905 of the pump 6 has one end fitted onto the rotating shaft 909 and the other end connected to the collar 908.

The support base 901 is connected to the rotating bracket 903, supporting the entire magnetic pump rotating device 9 and preventing horizontal displacement of the device.

[0037] A brief description of the working process of this embodiment: Step 1: Before starting the experiment, fill the water tank with the water required for the experiment. Fix the magnetic pump to be tested in the rotating device, rotate the magnetic pump to the angle to be tested and fix it. Then rotate the connecting rod to place the collar at a suitable angle, and connect the pump inlet and outlet pipes through the collar to the pump inlet and outlet respectively.

[0038] Step 2: Ensure the outlet valve and return valve are open. Turn on the flow meter and pressure sensor and connect them to the computer. Start the magnetic pump, which draws water from the pump inlet pipe and discharges it into the water tank through the pump outlet and return pipes, achieving a closed-loop water circulation. Observe the corresponding flow and pressure data, and finally calculate the pump head and flow rate. Compare the data with that of a magnetic pump installed horizontally to verify the reliability of the magnetic pump under abnormal installation angle conditions.

[0039] This embodiment provides a magnetic pump reliability testing device, wherein a water tank provides experimental water, and the water tank is connected to an outlet pipe and a return pipe, and is controlled by corresponding valves, and is then connected to the pump's inlet and outlet pipes, which are flexible hoses that can be adjusted slightly.

[0040] In this embodiment, the magnetic pump used in the experiment is installed in a rotating device. The rotating device is fixed to the ground by a support base to prevent vibration during operation. The magnetic pump is placed in the middle of the rotating device and is fixed to the rotating bracket by a rotating shaft and a set screw. This allows the magnetic pump to rotate around the rotating shaft in a 180-degree plane. When the magnetic pump rotates to the required angle, the set screw is inserted into the magnetic pump through the rotating groove B and tightened. The magnetic pump is fixed to the required angle by friction. Then, the connecting rod located in the rotating groove A is rotated. The magnetic pump can be installed and tested at different angles without disassembly.

[0041] The connecting rod is connected to the collar. Rotating the connecting rod can fix the collar in front of the inlet and outlet of the magnetic pump. The collar will fix the pump's inlet and outlet water pipes, reducing the possibility of the water pipes shaking and loosening during the test, and improving the stability and accuracy of the test.
