[0048] Figure 1 FIG. 1 is a schematic diagram of a pump 1 provided in an embodiment of the present disclosure. As an example, the pump 1 in this embodiment may be a centrifugal pump, in particular a shielded pump. Figure 1 As shown, the pump 1 includes a pump body 11 and a motor 12 connected to the pump body 11. The pump body 11 includes an end face 111. In this embodiment, the end face 111 is a surface on the pump body 11 away from the motor 12, and when the pump 1 is put into use, the end face 111 is used to connect with a water facility (not shown), such as a heating device. The end face 111 includes a water inlet 112 and a water outlet 113 facing the same direction. In this embodiment, the direction of the water inlet 112 and the direction of the water outlet 113 are both parallel to the axial direction of the motor 12. The water inlet 112 and the water outlet 113 are both connected to a pump chamber (not shown) located inside the pump body 11. An impeller (not shown) connected to the motor 12 is provided in the pump chamber. When the impeller rotates under the action of the motor 12, a medium (such as water) can enter the pump chamber from the water inlet 112 and can leave the pump chamber from the water outlet 113.

[0049] like Figure 1 As shown, the end surface 111 also includes a central portion 114 and an edge portion 115. The central portion 114 can be considered as a projection area formed by projecting the pump cavity on the end surface 111, and the edge portion 115 surrounds the periphery of the central portion 114. In this embodiment, the annular sealing groove 116 on the end surface 111 can be considered as the boundary line between the central portion 114 and the edge portion 115. The water inlet 112 and the water outlet 113 are both located in the central portion 114. Therefore, in Figure 1 In the embodiment, the distance between the water inlet 112 and the water outlet 113 is small, especially compared with the pump 1 in the prior art in which the water inlet 112 and the water outlet 113 face different directions.

[0050] In addition, if Figure 1 As shown, the outer periphery of the water inlet 112 is surrounded by a water inlet sealing groove 117 . The outer periphery of the water outlet 113 is adjacent to the annular sealing groove 116 .

[0051] In addition, if Figure 1As shown, the edge portion 115 is provided with a first connection portion 118, and when the pump 1 is put into use, the first connection portion 118 can be connected to the water facility so as to install the pump 1 on the water facility. As an example, the first connection portion 118 includes a first hole 1181, and a fastener can be installed in the first hole 1181, so as to connect the pump 1 to the water facility.

[0052] This embodiment provides an adapter for installation between the pump 1 and a test system (not shown). Figure 2 A schematic diagram of the upper portion of the switching device provided in this embodiment is shown. Figure 3 A schematic diagram of the lower part of the switching device provided in this embodiment is shown. Figure 4 FIG. 2 shows a cross-sectional view of the switching device provided in this embodiment. Figures 2 to 4 As shown, the adapter device includes a connecting plate 2, a water inlet pipe 3 and a water outlet pipe 4, wherein the connecting plate 2 includes a water inlet hole 21 corresponding to the water inlet 112 and a water outlet hole 22 corresponding to the water outlet 113, the water inlet pipe 3 is arranged on the connecting plate 2, and the first end 31 of the water inlet pipe 3 is connected to the water inlet hole 21, the water outlet pipe 4 is arranged on the connecting plate 2, and the first end 41 of the water outlet pipe 4 is connected to the water outlet hole 22.

[0053] When the adapter is used, the second end 32 of the water inlet pipe 3 is connected to the water outlet pipe 51 of the test system, the second end 42 of the water outlet pipe 4 is connected to the water return pipe 52 of the test system, the connecting plate 2 is detachably mounted to the end face 111 of the pump 1, and when the connecting plate 2 is mounted on the end face 111 of the pump 1, the water inlet hole 21 of the connecting plate 2 is aligned with the water inlet 112 of the pump 1, and the water outlet hole 22 of the connecting plate 2 is aligned with the water outlet 113 of the pump 1. Thus, with the help of the adapter, a loop is formed between the pump 1 and the test system.

[0054] It should be noted that the water inlet pipe 3 and the water outlet pipe 4 can be as follows Figure 2 As shown, the pipe is independent of the connecting plate 2. However, in an embodiment not shown, the water inlet pipe 3 and the water outlet pipe 4 may also be a part located inside the connecting plate 2. For example, the connecting plate 2 has one or more pipes inside, and the one or more pipes serve as the water inlet pipe 3 or the water outlet pipe 4.

[0055] It should be noted that the test system belongs to the prior art, for example, it can be a water pump test bench, and the specific structure and control method are not described in detail here.

[0056] Figure 5 FIG. 2 shows a top view of the connecting plate 2 provided in this embodiment. Figure 5 As shown, the connecting plate 2 further includes a second connecting portion 23 . When the connecting plate 2 is mounted to the end surface 111 of the pump 1 , the second connecting portion 23 is detachably connected to the first connecting portion 118 , so that the connecting plate 2 can be detachably mounted to the end surface 111 .

[0057] As an example, the second connecting portion 23 includes a second hole 231 , and the fastener 9 is detachably mounted in the first hole 1181 of the pump 1 and the second hole 231 of the connecting plate 2 .

[0058] Specifically, in this embodiment, the first hole 1181 is a through hole, the second through hole is a threaded hole, the fastener 9 is a bolt, and the screw of the bolt first passes through the first hole 1181 and is then threadedly connected to the second hole 231. However, in other embodiments not shown, the first hole 1181 may be a threaded hole, and the second hole 231 may be a through hole.

[0059] like Figure 5 As shown, similar to the end face 111 of the pump 1, the connecting plate 2 includes a central area 24 and an edge area 25, the water inlet hole 21 and the water outlet hole 22 on the connecting plate 2 are both located in the central area 24, and the second connecting portion 23 on the connecting plate 2 is located in the edge area 25. The central area 24 roughly corresponds to the central portion 114 of the pump 1, and the edge area 25 roughly corresponds to the edge portion 115 of the pump 1. Specifically, when the connecting plate 2 is mounted to the end face 111 of the pump 1, the central area 24 is substantially aligned with the central portion 114, and the edge area 25 is substantially aligned with the edge portion 115.

[0060] like Figure 3 As shown, the connection plate 2 further includes an inlet flange 26, an annular flange 27 and an outlet flange 28. The inlet flange 26 corresponds to the inlet sealing groove 117 and surrounds the water inlet hole 21. The annular flange 27 corresponds to the annular sealing groove 116, and the annular flange 27 serves as a boundary between the central area 24 and the edge area 25. The outlet flange 28 corresponds to the water outlet 113 and surrounds the water outlet hole 22, and the outlet flange 28 is connected to the annular flange 27.

[0061] When the connecting plate 2 is installed to the end face 111 of the pump 1, the water inlet flange 26 is aligned with the water inlet sealing groove 117 of the pump 1, the annular flange 27 is aligned with the annular sealing groove 116 of the pump 1, and the water outlet flange 28 is aligned with the water outlet 113 of the pump 1 to ensure the sealing between the connecting plate 2 and the end face 111 of the pump 1.

[0062] like Figure 6 As shown, in order to further improve the sealing effect, the water inlet sealing gasket 61 can be detachably installed in the water inlet sealing groove 117 of the pump 1, and the annular sealing gasket 62 can be detachably installed in the annular sealing groove 116 of the pump 1, and the annular sealing gasket 62 has a water outlet sealing portion 621. When the annular sealing gasket 62 is installed to the annular sealing groove 116 of the pump 1, the water outlet sealing portion 621 abuts against the surface of the water outlet 113 of the pump 1.

[0063] Therefore, when the connecting plate 2 is installed to the end face 111 of the pump 1, the water inlet flange 26 presses the water inlet sealing gasket 61 into the water inlet sealing groove 117, the annular flange 27 presses the annular sealing gasket 62 into the annular sealing groove 116, and the water outlet flange 28 presses the water outlet sealing part 621 onto the surface of the water outlet 113.

[0064] like Figure 2 As shown, in this embodiment, the water inlet pipe 3 can be integrally formed on the connecting plate 2. Specifically, the water inlet pipe 3 can be integrally formed on the connecting plate 2 by welding.

[0065] like Figure 2 As shown, in this embodiment, the water outlet pipe 4 can be integrally formed on the connecting plate 2. Specifically, the water outlet pipe 4 can be integrally formed on the connecting plate 2 by welding.

[0066] like Figure 2 As shown, in this embodiment, the water outlet pipe 4 has a bent portion 44, so that the direction of the second end 42 of the water outlet pipe 4 is different from the direction of the first end of the water storage pipe, thereby increasing the distance between the water outlet pipe 4 and the water inlet pipe 3, so as to facilitate the installation of the return pipe 52 of the test system on the water outlet pipe 4 and the installation of the water outlet pipe 51 of the test system on the water inlet pipe 3. Of course, in other embodiments not shown, the water inlet pipe 3 may have a bent portion 44.

[0067] like Figure 2 As shown, in this embodiment, the second end 32 of the water inlet pipe 3 has a first flange 33 , and the first flange 33 can be detachably connected to the water outlet pipe 51 through a first clamp 7 .

[0068] like Figure 2 As shown, in this embodiment, the second end 42 of the water outlet pipe 4 has a second flange 43 , and the second flange 43 can be detachably connected to the return pipe 52 through a second clamp 8 .

[0069] When the water inlet pipe 3 and / or the water outlet pipe 4 has a bent portion 44 , it is convenient to install the first clamp 7 and / or the second clamp 8 .

[0070] Figure 7 FIG. 2 shows a schematic diagram of the adapter provided in this embodiment connecting the pump 1 and the testing device together. Figure 7 As shown, the installation process of pump 1, adapter and test system is as follows:

[0071] First, install the connecting plate 2 to the end surface 111 of the pump 1, and align the water inlet 21 of the connecting plate 2 with the water inlet 112 of the pump 1, and align the water outlet 22 of the connecting plate 2 with the water outlet 113 of the pump 1;

[0072] Then, the first hole 1181 of the pump 1 and the second hole 231 of the connecting plate 2 are connected together using the fastener 9 to fix the connecting plate 2 to the pump 1;

[0073] Finally, the second end 32 of the water inlet pipe 3 is connected to the water outlet pipe 51 of the test system using the first clamp 7, and the second end 42 of the water outlet pipe 4 is connected to the water return pipe 52 of the test system using the second clamp 8.

[0074] Thus, with the help of the adapter, a loop is formed between the pump 1 and the test system so that the test system can perform one or more tests on the pump 1 .

[0075] 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.
