Description

Technical Field

[0001] The utility model relates to the technical field of electric pump testing, in particular to electric pump testing equipment. Background Art

[0002] An electric pump is a device used for liquid transportation. When working, it relies on its own motor to drive the impeller to rotate, and then pressurizes the liquid in one station and pumps it out to another station. In order to ensure the quality of the products shipped and ensure that the electric pump can work properly, manufacturers and end users, especially electric pump manufacturers, will use test equipment to test its performance.

[0003] Existing electric pump testing technology often uses an electric pump testing device such as the one disclosed in announcement number CN218563868U, which opens the first regulating valve and adds tap water or other test liquid into the liquid tank. The electric pump is powered on to generate negative pressure to draw the liquid in the liquid tank out of the liquid outlet pipe, and then flows back into the liquid tank through the liquid inlet pipe. During the liquid circulation outflow and inflow process, the tester can intuitively grasp the liquid pressure data output by the electric pump by observing the pressure data detected by the pressure sensor displayed on the LCD screen interface of the operation screen, and the flow data detected by the flow sensor. When the electric pump drains water, the discharged water contains bubbles and impurities in the electric pump, and the discharged liquid needs to be recycled. When it is extracted by the electric pump again, the above two substances will directly affect the accuracy of the test results. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3 The electric pump test equipment includes a main body 1 and an electric pump 2. The main body 1 is provided with an instrument panel for feeding back data and controlling the equipment. Both sides of the main body 1 are provided with heat dissipation holes 3. The equipment will generate a large amount of heat during operation. As is well known, overheating of the equipment will affect its performance, which will in turn affect the test results. Therefore, heat dissipation holes 3 are opened on both sides of the main body 1, and the heat will be discharged from the main body 1 through the heat dissipation holes 3 to achieve a heat dissipation effect. The rear side of the main body 1 is provided with an interface module, and the front side of the main body 1 is provided with two sets of wastewater outlets 4 for treating wastewater.

[0022] A circulating water tank 5 and a constant temperature water tank 6 are arranged in the main body 1. A heating pipe and a circulating water pump for uniformly heating the water body are arranged in the constant temperature water tank 6. The constant temperature water tank 6 is equipped with an intelligent temperature control system, through which the water temperature in the constant temperature water tank 6 can be freely controlled. A quality inspection mechanism for testing the electric pump 2 is arranged in the circulating water tank 5.

[0023] The quality inspection mechanism includes a support plate 14 welded in the circulating water tank 5, a reflux baffle 15 is fixedly installed on the support plate 14, and a reflux outlet 16 is opened on the reflux baffle 15, and a filter sponge 17 is filled on the right side of the reflux baffle 15. The porosity of the filter sponge 17 is as high as 97%, and it has excellent air permeability, good softness and high mechanical strength, and high filtration efficiency. It can be repeatedly washed with water and can effectively filter impurities and bubbles in the electric pump 2. A fixing frame 18 is fixedly installed on the support plate 14, and a filter screen 19 is fixedly installed at the bottom end of the fixing frame 18. The filter screen 19 and the filter sponge 17 form a double guarantee to ensure the accuracy of the measurement result. A water pump housing 20 for placing the electric pump 2 is fixedly installed in the fixing frame 18, and a water outlet pipe 21 fixedly connected to the water pump housing 20 is placed on the filter sponge 17. A flow sensor 22 is installed on the water outlet pipe 21. The flow sensor 22 is a sensor for measuring the liquid flow in the water outlet pipe 21, and the measured result will be fed back to the database through the data line.

[0024] The fixing frame 18 is fixedly installed at the left side position of the reflux baffle 15, and a through hole is opened on the support plate 14 at the bottom end position of the fixing frame 18. The middle end position of the water outlet pipe 21 conflicts with the reflux baffle 15. The reflux baffle 15, the water pump housing 20 and the filter sponge 17 limit the position of the water outlet pipe 21 to reduce the shaking of the water outlet pipe 21 when it is in working state.

[0025] The instrument panel includes a control hub template and an information feedback template. The control hub template includes a power switch 7, a power button 8, a start button 9 and a product terminal 23. The information feedback template includes a voltage and current meter 10, a flow meter 11, a product data table 12 and an indicator light 13.

[0026] The interface module includes a power interface, a VGA interface, an HDMI interface, a USB interface and a network interface.

[0027] It should be noted that the specific model and specifications of the electric pump 2 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0028] The functional principle of the utility model can be explained through the following operation modes:

[0029] Inject liquid into the circulating water tank 5 and the constant temperature water tank 6, and fix the electric pump 2 in the water pump housing 20 from the top of the fixing frame 18 by rotating and snapping. Turn on the power switch 7, the power button 8, and the start button 9 in sequence. At this time, the heating pipe and the circulating water pump evenly heat the liquid in the constant temperature water tank 6, and the water temperature is controlled by the intelligent temperature control system.

[0030] In the circulating water tank 5, the electric pump 2 extracts the liquid, and the liquid passes through the flow sensor 22, and the data is displayed on the product data sheet 12. When the electric pump 2 discharges the liquid, the liquid will penetrate into the filter sponge 17 and return to the circulating water tank 5 from the reflux outlet 16. During this period, the filter sponge 17 will filter impurities and bubbles.

[0031] After the liquid in the thermostatic water tank 6 is heated, the electric pump 2 is placed in the thermostatic water tank 6 to observe whether the electric pump 2 leaks or bubbles at high temperature;

[0032] The above data will be displayed in the information feedback template, automatically saved after the test is completed, and uploaded to the server.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
