Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a testing device for verifying pump performance. Background Technology

[0002] A water pump is a conventional machine that transfers mechanical energy to a liquid, thereby pressurizing or transporting the liquid. It is widely used in various fields, and therefore, the performance of a water pump largely determines the production performance of a company. Thus, before a batch of water pumps is produced and released to the market, it is necessary to periodically sample some products for performance testing to ensure their performance and service life under normal operating conditions. However, water pumps are affected by various factors (ambient temperature, humidity, medium temperature, pressure, flow rate, etc.) in actual operating environments. Existing performance testing methods for water pumps can only test one or a few of these factors, failing to comprehensively simulate the complex environmental impact of multiple factors in actual operation. This results in long testing cycles, low efficiency, and an inability to accurately test and provide feedback on the pump's performance and service life. Therefore, there is an urgent need for a testing device to verify pump performance and overcome the shortcomings of existing testing methods for water pump performance testing. Utility Model Content

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0018] Please see Figure 1-5This utility model provides an embodiment of a testing device for verifying pump performance, comprising a water tank 1, a cooling system 2 on one side of the water tank 1 for cooling the liquid in the water tank 1, and a testing system 3 on the other side of the water tank 1; the testing system 3 includes a test pump 31, which is connected to a first inlet 11 on the water tank 1 via a first connecting pipe 30, and to a first outlet 14 on the water tank 1 via a second connecting pipe 35; a sensor assembly 311 is also provided on the first connecting pipe 30, and an electric proportional valve 36 is installed between the sensor assembly 311 and the water tank 1; when the speed of the test pump 31 remains constant, the opening of the electric proportional valve 36 is adjusted, and the data generated by the test pump 31 is output to the outside using the sensor assembly 311. Based on this, the device can transmit the acquired data to the outside world through the sensor component 311, for example, to an external water pump integrated testing platform. Then, the water pump integrated testing platform can display the acquired information to the user. For example, the water pump integrated testing platform can summarize various data, including parameters such as pressure, flow rate, temperature, pump speed, and pump current, and display the acquired information in the form of curves.

[0019] In addition, when the sensor assembly 311 is a first temperature sensor 310, a flow sensor 39, and a first pressure sensor 38, it outputs relevant parameters of the test pump 31, such as temperature information, pressure information, and flow information, and displays the information processed and obtained by the water pump comprehensive tester.

[0020] In practical applications, the rotational speed of the test pump 31 remains constant. By adjusting the electric proportional valve 36, the outlet flow rate, pressure, and power of the customer's test pump 31 are recorded. Multiple sets of data are recorded by adjusting the opening of the electric proportional valve 36 multiple times, and curves are plotted using a comprehensive pump tester. Alternatively, by keeping the opening of the electric proportional valve 36 constant, the rotational speed of the test pump 31 is adjusted multiple times, and the outlet flow rate, pressure, and power of the customer's test pump 31 are recorded. Multiple sets of data are recorded, and curves are plotted using a comprehensive pump tester. Based on this, this testing equipment can provide pump manufacturers and pump end-users with various parameters required for design, production, and use.

[0021] Furthermore, since the second connecting pipe 35 is also equipped with a second temperature sensor 33 and a second pressure sensor 34, the liquid data entering the test pump 31, such as temperature data and pressure data, can be output to the water pump integrated test platform using the second temperature sensor 33 and the second pressure sensor 34, thus enabling reliable monitoring of the data entering the test pump 31.

[0022] Furthermore, since a first manual valve 37 is provided between the first temperature sensor 310 and the test pump 31, and a second manual valve 32 is provided between the second temperature sensor 33 and the test pump 31, the setting of the two manual valves allows the entire test system 3 to be manually controlled to control whether the liquid can flow.

[0023] Based on the above scheme, the cooling system 2 includes a heat exchanger 23. The heat exchanger 23 is connected to the second water inlet 10 on the water tank 1 through a third connecting pipe 20, and the other side of the heat exchanger 23 is connected to the second water outlet 15 on the water tank 1 through a fourth connecting pipe 21. Therefore, heat exchange can be performed using the heat exchanger 23 to regulate the water temperature inside the water tank 1.

[0024] Meanwhile, the fourth connecting pipe 21 is also equipped with a circulation pump 22, which promotes the circulation of liquid in the cooling system 2. Therefore, the circulation pump 22 can be used to promote the flow of liquid so that the liquid can enter the heat exchanger 23 for heat exchange.

[0025] Furthermore, since a variable frequency fan 24 is provided on the side of the heat exchanger 23 away from the water tank 1, the heat of the heat exchanger 23 can be carried away by the variable frequency fan 24 to cool the circulating liquid; further still, when the temperature of the circulating liquid in the water tank 1 is lower than the set value, the circulating liquid can be heated by the heater 13; wherein the heat exchanger 23 is a wind-water heat exchanger.

[0026] In addition, the water tank 1 is also equipped with a liquid level sensor 16 and a third temperature sensor 12. Therefore, the liquid level inside the water tank 1 can be monitored in real time by using the liquid level sensor 16, and the water temperature inside the water tank 1 can be output to the outside in real time by using the third temperature sensor 12.

[0027] In summary, the first circulating pump 22 draws circulating fluid from the water tank 1 and delivers it to the heat exchanger 23. In the heat exchanger 23, the circulating fluid is cooled by adjusting the speed of the variable frequency fan 24 and exchanging heat with the air. When the temperature in the water tank 1 is lower than the set value, it is heated by the heater 13. The antifreeze at the appropriate temperature then passes through the second pressure sensor 34, the second temperature sensor 33, and the second hand valve 32 before entering the test pump 31. From the test pump 31, it passes through the first hand valve 37, the first temperature sensor 310, the flow sensor 39, the first pressure sensor 38, and the electric proportional valve 36 before entering the water tank 1.

[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
