Description

Technical Field

[0001] The present disclosure relates to the field of pump technology, and more particularly to a pump testing system. Background Art

[0002] During the production process, the pump needs to undergo a variety of tests, such as vibration test, high and low temperature operation test, acoustic test, etc. During the test, the medium inlet of the pump is connected to the medium container (such as a water tank) through a medium delivery pipeline, and the medium outlet of the pump is connected to the medium container through a medium return pipeline, thereby forming a loop between the pump and the medium container, so that the parameters of the pump in operation can be collected using, for example, sensors, in order to determine whether the pump meets the relevant requirements.

[0003] Pumps have various specifications. The water inlets of pumps of different specifications may have different inner diameters, and the same is true for the water outlets. During testing, the inner diameter of the water inlet must be equal to the inner diameter of the medium delivery pipeline, and the inner diameter of the water outlet must be equal to the inner diameter of the medium return pipeline. Therefore, for pumps of different specifications, it may be necessary to replace the medium delivery pipeline and the medium return pipeline.

[0004] However, replacing the pipes takes a lot of time. Utility Model Content

[0005] It is an object of the present disclosure to provide a pump testing system which does not have the above mentioned drawbacks.

[0006] To achieve this object, the present disclosure provides a pump testing system, which is applied to a test room, and the pump testing system comprises:

[0007] Medium container;

[0008] A medium delivery pipeline, the inlet end of which is connected to the medium container;

[0009] A medium return pipe, the outlet end of which is connected to the medium container;

[0010] A first multi-way valve, wherein the first multi-way valve has a first common end and a plurality of first selection ends, wherein the first common end is connected to the outlet end of the medium delivery pipeline, and each of the plurality of first selection ends is selectively connected to the first common end;

[0011] A plurality of first transfer fixtures, wherein the plurality of first transfer fixtures are configured to be arranged inside the test chamber, and the inlet ends of the plurality of first transfer fixtures are connected to the plurality of first selection ends in a one-to-one correspondence;

[0012] a second multi-way valve, the second multi-way valve having a second common end and a plurality of second selection ends, the second common end being connected to the inlet end of the medium return pipe, and each of the plurality of second selection ends being selectively connected to the second common end; and

[0013] A plurality of second transfer fixtures, wherein the plurality of second transfer fixtures are configured to be arranged inside the test chamber, and the outlet ends of the plurality of second transfer fixtures are connected to the plurality of second selection ends in a one-to-one correspondence;

[0014] Wherein, each of the plurality of first transfer fixtures has a different inner diameter, and each of the plurality of second transfer fixtures has a different inner diameter.

[0015] According to the test system disclosed in the present invention, when the specification of the pump to be tested changes, a first adapter fixture corresponding to the inner diameter of the medium inlet of the pump can be selected from a plurality of first adapter fixtures, and connected to the medium inlet of the pump, thereby avoiding the need to replace the medium delivery pipeline; similarly, a second adapter fixture corresponding to the inner diameter of the medium outlet of the pump can be selected from a plurality of second adapter fixtures, and connected to the medium outlet of the pump, thereby avoiding the need to replace the medium return pipeline. In addition, by controlling the on-off between the first selection end and the first common end of the first multi-way valve, the on-off between the first adapter fixture and the medium delivery pipeline can be controlled; similarly, by controlling the on-off between the second selection end and the second common end of the second multi-way valve, the on-off between the second adapter fixture and the medium return pipeline can be controlled, thereby forming a loop between the medium container and the pump to achieve pump testing.

For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0032] Figure 1 FIG. 2 shows a schematic diagram of a pump testing system provided by an embodiment of the present disclosure. Figure 1As shown, the pump testing system of the present disclosure is applied to a test room 1, which is a room for testing a pump 2. During the test, the pump 2 is located in the test room 1. In the test room 1, one or more tests can be performed on the pump 2, such as a vibration test, a high and low temperature operation test, an acoustic test, etc.

[0033] like Figure 1 As shown, the pump testing system of the present disclosure comprises a medium container 3, which is used to store a medium, such as a liquid, especially water.

[0034] The medium container 3 can be located inside the test chamber 1 or outside the test chamber 1, which usually depends on the type of test. For example, when the pump 2 is subjected to an acoustic test, the medium container 3 is located outside the test chamber 1 to minimize the sound inside the test chamber 1 except for the pump 2. For example, when the pump 2 is subjected to a high and low temperature operation test, the medium container 3 can be located inside the test chamber 1.

[0035] In this embodiment, the acoustic test of pump 2 is taken as an example. Figure 1 In the embodiment, the medium container 3 is located outside the test chamber 1 .

[0036] In an optional embodiment, the medium container 3 can have a pressurization and / or heating function, so that the pressure and / or temperature of the medium can be adjusted to facilitate a more comprehensive test of the pump 2, such as performing high and low temperature operation tests simultaneously during an acoustic test of the pump 2.

[0037] As an example, a pressure pump (not shown) and / or a heating component (not shown) may be disposed inside the medium container 3 . The heating component may be an electric heating component capable of generating Joule heat, such as a heating wire.

[0038] Furthermore, in an optional embodiment, a pressure sensor 31 for detecting pressure and / or a temperature sensor 32 for detecting temperature may be provided on the medium container 3 .

[0039] like Figure 1 As shown, the pump testing system of the present disclosure further includes a medium delivery pipeline 4, the inlet end of the medium delivery pipeline 4 is connected to the medium container 3, and the medium delivery pipeline 4 is used to deliver the medium in the medium container 3 to the outside.

[0040] It should be noted that the medium delivery pipeline 4 can be located entirely outside the test chamber 1, or inside the test chamber 1, or can be passed through the wall of the test chamber 1. In this embodiment, since the acoustic test of the pump 2 is taken as an example, the medium delivery pipeline 4 extends from the outside to the inside of the test chamber 1.

[0041] In an optional embodiment, a first valve 41 can be provided on the medium delivery pipeline 4, and the first valve 41 is used to control the on-off of the medium delivery pipeline 4. Specifically, when the first valve 41 is opened, the inlet end and the outlet end of the medium delivery pipeline 4 are connected to each other, and the medium can flow from the inlet end to the outlet end. Otherwise, the medium cannot flow from the inlet end to the outlet end.

[0042] like Figure 1 As shown, the pump testing system of the present invention also includes a first multi-way valve 5, which includes a first common end 51 and a plurality of first selection ends 52. The first common end 51 is connected to the outlet end of the medium delivery pipeline 4, and each of the plurality of first selection ends 52 is selectively connected to the first common end 51; generally, at the same time, one of the plurality of first selection ends 52 is connected to the first common end 51.

[0043] It should be noted that although Figure 1 The first multi-way valve 5 in the embodiment has three first selection ends 52, but in the embodiment not shown, the first multi-way valve 5 may also have two or more first selection ends 52, that is, the first multi-way valve 5 in the present disclosure may be Figure 1 In addition to the four-way valve, it can also be a three-way valve, a five-way valve, a six-way valve, etc.

[0044] It should be noted that the first multi-way valve 5 can be a solenoid valve or a mechanical valve.

[0045] It should also be noted that the first multi-way valve 5 can be located inside the test chamber 1 or outside the test chamber 1. In this embodiment, since the acoustic test of the pump 2 is taken as an example, the first multi-way valve 5 is located inside the test chamber 1.

[0046] like Figure 1 As shown, the pump test system of the present disclosure further includes a plurality of first adapter fixtures 6 located inside the test chamber 1, and the inlet ends of the plurality of first adapter fixtures 6 are connected to the plurality of first selection ends 52 in a one-to-one correspondence. Specifically, Figure 1 In the embodiment, the number of the first adapter fixtures 6 is three, and the number of the first selection terminals 52 is also three, so each first adapter fixture 6 is connected to a corresponding first selection terminal 52. It should be noted that when the number of the first selection terminals 52 changes, the number of the first adapter fixtures 6 can change accordingly, and vice versa.

[0047] like Figure 1As described above, in the present disclosure, the outlet end of one of the first adapter fixtures 6 is connected to the medium inlet 21 of the pump 2. Thus, when the first selection end 52 corresponding to the first adapter fixture 6 is connected to the first common end 51, the medium in the medium container 3 can enter the medium inlet 21 of the pump 2 through the medium delivery pipeline 4, the first multi-way valve 5 and the first adapter fixture 6.

[0048] It should be noted that each of the multiple first adapter fixtures 6 in the present disclosure has a different inner diameter. Therefore, when the pump 2 to be tested has different specifications, a first adapter fixture 6 with an inner diameter equal to the inner diameter of the medium inlet 21 of the pump 2 can be selected from the multiple first adapter fixtures 6, thereby realizing the connection between the pump 2 and the medium container 3.

[0049] As an example, the first adapter tool 6 can be a hose, and a flange can be set at the inlet end of the hose so as to be connected to the first selection end 52 of the first multi-way valve 5. The outlet end of the hose can be set with threads and flanges so as to be connected to the medium inlet 21 of the pump 2, and can also be connected to the medium inlet 21 of the pump 2 using a clamp.

[0050] like Figure 1 As shown, the pump testing system of the present disclosure further includes a medium return pipe 7 , the outlet end of which is connected to the medium container 3 , and the medium return pipe 7 is used to return the high-pressure medium pumped out of the pump to the medium container 3 .

[0051] like Figure 1 As shown, the pump testing system of the present invention also includes a second multi-way valve 9, which includes a second common end 91 and a plurality of second selection ends 92. The second common end 91 is connected to the outlet end of the medium delivery pipeline 4, and each of the plurality of second selection ends 92 is selectively connected to the second common end 91; generally, at the same time, one of the plurality of second selection ends 92 is connected to the second common end 91.

[0052] It should be noted that although Figure 1 The second multi-way valve 9 in the embodiment has three second selection ends 92, but in the embodiment not shown, the second multi-way valve 9 may also have two or more second selection ends 92, that is, the second multi-way valve 9 in the present disclosure may be Figure 1 In addition to the four-way valve, it can also be a three-way valve, a five-way valve, a six-way valve, etc.

[0053] It should be noted that the second multi-way valve 9 can be a solenoid valve or a mechanical valve.

[0054] It should also be noted that the second multi-way valve 9 can be located inside the test chamber 1 or outside the test chamber 1. In this embodiment, since the acoustic test of the pump 2 is taken as an example, the second multi-way valve 9 is located inside the test chamber 1.

[0055] like Figure 1 As shown, the pump test system of the present disclosure further includes a plurality of second adapter fixtures 8 located inside the test chamber 1, and the inlet ends of the plurality of second adapter fixtures 8 are connected to the plurality of second selection ends 92 in a one-to-one correspondence. Specifically, Figure 1 In the embodiment, the number of the second adapter fixtures 8 is three, and the number of the second selection terminals 92 is also three, so each second adapter fixture 8 is connected to a corresponding second selection terminal 92. It should be noted that when the number of the second selection terminals 92 changes, the number of the second adapter fixtures 8 can change accordingly, and vice versa.

[0056] like Figure 1 As described above, in the present disclosure, the outlet end of one of the second adapter fixtures 8 is connected to the medium outlet 22 of the pump 2. Thus, when the second selection end 92 corresponding to the second adapter fixture 8 is connected to the second common end 91, the high-pressure medium pumped out of the medium outlet 22 of the pump 2 can flow back into the medium container 3 through the second adapter fixture 8, the second multi-way valve 9 and the medium return pipe 7.

[0057] It should be noted that each of the multiple second adapter fixtures 8 in the present disclosure has a different inner diameter. Therefore, when the pump 2 to be tested has different specifications, a second adapter fixture 8 with an inner diameter equal to the inner diameter of the medium outlet 22 of the pump 2 can be selected from the multiple second adapter fixtures 8, thereby realizing the connection between the pump 2 and the medium container 3.

[0058] As an example, the second transfer tool 8 can be a hose, and a flange can be set at the inlet end of the hose so as to be connected to the second selection end 92 of the second multi-way valve 9. The outlet end of the hose can be set with threads and flanges so as to be connected to the medium outlet 22 of the pump 2, or it can be connected to the medium outlet 22 of the pump 2 using a clamp.

[0059] To sum up, by setting a first multi-way valve 5, multiple first adapter fixtures 6, a second multi-way valve 9 and multiple second adapter fixtures 8, the replacement of the medium delivery pipeline 4 and the medium return pipeline 7 can be avoided. When the medium delivery pipeline 4 and the medium return pipeline 7 are passed through the wall of the test room 1, the solution of this embodiment has significant advantages and can significantly improve the test efficiency.

[0060] In an optional embodiment, a flow meter 71 may be provided on the medium return pipe 7 to detect the flow rate pumped out by the pump 2. In addition, a second valve 72 may be provided on the medium return pipe 7, and the second valve 72 is used to control the on-off of the medium return pipe 7. Specifically, when the second valve 72 is opened, the inlet end and the outlet end of the medium return pipe 7 are connected to each other, and the medium can flow from the inlet end to the outlet end. Conversely, the medium cannot flow from the inlet end to the outlet end.

[0061] like Figure 1 As shown, in an optional embodiment, the pump testing system may further include a lifting platform 11 located inside the test chamber 1, the lifting platform 11 having a supporting surface 811 that can be raised and lowered, and the pump 2 can be placed on the supporting surface 811, so that the height of the pump 2 can be adjusted. For example, when the pump 2 needs to be placed on the supporting surface 811, the supporting surface 811 can be lowered to facilitate the placement of the pump 2, and when the pump 2 needs to be tested, the supporting surface 811 can be raised.

[0062] As an example, the lifting platform 11 may include a scissor mechanism to achieve lifting and lowering of the support surface 811 .

[0063] Figure 2 FIG. 1 shows a top view of a test chamber 1 provided in an embodiment of the present disclosure, and some structures are omitted in the figure. Figure 2 As shown, in an optional embodiment, the pump testing system may further include a sensor 12 located inside the testing chamber 1 , and the sensor 12 is used to collect parameters of the pump 2 in a running state.

[0064] like Figure 2 As shown, in an optional embodiment, the pump testing system further comprises a bracket (not shown) located inside the testing chamber 1 , the bracket is located on one side of the supporting surface 811 , and the sensor 12 is mounted on the bracket.

[0065] In an alternative embodiment, the bracket can be moved in the test chamber 1 to facilitate adjustment of the position of the sensor 12 .

[0066] In an optional embodiment, the bracket and the support surface 811 can be raised and lowered so that the sensor 12 is at the same height as the pump 2. As an example, the bracket can include a scissor mechanism to achieve the lifting and lowering of the bracket.

[0067] In addition, the support and the lifting platform 11 may be provided with a ruler (not shown) to observe the height difference from the ground.

[0068] In addition, the number of brackets can be one or more, for example Figure 2 In the embodiment, there are four brackets, which are respectively placed on the pump body side, the motor side, the medium inlet 21 side and the medium outlet 22 side of the pump 2 .

[0069] In this embodiment, the test room 1 is a silent room, which is an acoustic laboratory that can effectively isolate external noise, so as to test the noise of the pump 2. The sensor 12 may include a microphone to collect acoustic data of the pump 2 in operation.

[0070] The main structure of the silent room uses sound insulation materials with good sealing and high density, such as sound insulation cotton with damping sound insulation felt and keel to reduce the spread of sound. The interior of the silent room uses flame-retardant and fire-proof sound-absorbing materials, such as polyester fiber sound-absorbing panels. The gaps in the silent room structure are filled with sealing strips, sound insulation glue and other materials to achieve an effective closure effect.

[0071] In an optional embodiment, to facilitate operation and observation, a monitoring camera 13 is installed in the test room 1, and a display (not shown) coupled to the monitoring camera 13 is installed outside the test room 1. The display is used to display image information obtained by the monitoring camera 13 so that test personnel can observe the actual indoor test situation in real time.

[0072] The above is a description of the embodiments of the present disclosure. Through the above description of the disclosed embodiments, professionals and technicians in the field can implement or use the present disclosure. Various modifications to these embodiments will be apparent to professionals and technicians in the field.
