[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0032] Specifically, such as Figures 1-4 As shown in the figure, this application embodiment provides a water pump mechanical seal disassembly device, which mainly includes a sealing ring clamping device 100 and a pump body clamping device 200. The sealing ring clamping device 100 is provided with a threaded rod 110, a first clamping rod 131, a support rod 132, and a first adjusting member 120. The first clamping rod 131 is connected to the threaded rod 110 through the support rod 132 and the first adjusting member 120. Specifically, one end of the first clamping rod 131 is rotatably connected to one end of the support rod 132, and the end of the support rod 132 away from the first clamping rod 131 is rotatably connected to the first adjusting member 120. At the same time, a support rod 132 is also provided at the middle position of the first clamping rod 131. One end of the support rod 132 is rotatably connected to the middle of the first clamping rod 131, and the other end of the support rod 132 is rotatably connected to the threaded rod 110.

[0033] In this embodiment, four first clamping rods 131 and four support rods 132 are provided. The four first clamping rods 131 and the four support rods 132 form a clamping assembly 130. At the same time, the four first clamping rods 131 are installed in a ring around the threaded rod 110, which facilitates the first clamping rods 131 to clamp the mechanical seal sealing ring and the end face of the rotating ring and the end face of the stationary ring, thereby avoiding damage to the mechanical seal sealing ring and the end face of the rotating ring and the end face of the stationary ring.

[0034] Correspondingly, a rotating base 121 is provided on the first adjusting member 120, and the support rod 132 is connected to the rotating base 121 so that the support rod 132 and the first adjusting member 120 are rotatably connected.

[0035] In the embodiments of this application, such as Figure 2As shown, the threaded rod 110 is configured in two parts. One part has a threaded ring, and the other part is a support rod 132 without threads. Two support rods 132 are provided on the same first clamping rod 131. One end of one support rod 132 is rotatably connected to one end of the first clamping rod 131, and the other end is rotatably connected to the first adjusting member 120. The first adjusting member 120 is sleeved on the threaded rod 110. One end of the other support rod 132 is connected to the middle of the first clamping rod 131, and the other end is rotatably connected to the unthreaded rod 110.

[0036] A clamping end 1311 is provided at the end of the first clamping rod 131 away from the support rod 132. An abutment block 1312 is provided on the clamping end 1311. The four abutment blocks 1312 surround and can abut and clamp the mechanical seal sealing ring, the dynamic ring end face, and the stationary ring end face, making it convenient to pick up and put down the mechanical seal sealing ring, the dynamic ring end face, and the stationary ring end face.

[0037] In this embodiment of the application, a pressure sensor is provided on the abutment block 1312. The pressure sensor is located at one end of the abutment block 1312 in the direction of the inner circle. The inner circle is formed by the four abutment blocks 1312 enclosing a first clamping opening 140, which is a circular design, so that the abutment blocks 1312 are oriented towards the center of the clamping opening.

[0038] When a pressure value appears on the pressure sensor, the pressure sensor transmits the value to the control center. The control center then digitally displays the pressure value for personnel to view, allowing personnel to adjust the distance between the first adjustment component 120 and the threaded rod 110 based on the value. This facilitates the removal of the mechanical seal sealing ring and the end faces of the rotating and stationary rings.

[0039] In the above, the first clamping opening 140 can change according to the adjustment of the first adjusting member 120, and the first adjusting member 120 moves linearly on the threaded rod 110. Specifically, in this embodiment, when the first adjusting member 120 is in the first position, the radius of the first clamping opening 140 on the first clamping rod 131 is small, which can clamp the mechanical seal sealing ring and the end face of the rotating ring and the end face of the stationary ring with a small radius; when the radius of the first clamping opening 140 on the first clamping rod 131 is large, it can clamp the mechanical seal sealing ring and the end face of the rotating ring and the end face of the stationary ring with a large radius.

[0040] In this embodiment, the pump body clamping device 200 includes a fixed rod 210, a second clamping rod 220, and a second adjusting member 230. The second clamping rod 220 is clamped and adjusted via the second clamping member. Specifically, the pump body clamping device 200 also includes a connecting member 250, whose two ends are connected to the second clamping rod 220 and the second adjusting member 230, respectively. The second adjusting member 230 is sleeved on the fixed rod 210. Adjustment of the second adjusting member 230 on the fixed rod 210 allows for the opening and retraction of the second clamping rod 220. In this embodiment, the second clamping rod 220 is provided with two connectors 250. One connector 250 is connected to one end of the second clamping rod 220, and the other connector 250 is connected to the middle part of the second clamping rod 220, so that the second clamping rod 220 can move through the connector 250. The end of the connector 250 away from the second clamping rod 220 is connected to the second adjusting member 230, so that the fixed rod 210 is provided with two second adjusting members 230, and both second adjusting members 230 are sleeved on the outside of the fixed rod 210.

[0041] The second adjusting member 230 mainly includes an adjusting ring 231, which is sleeved on the fixed rod 210. Multiple positioning blocks 232 are provided on the adjusting ring 231, evenly distributed around its periphery, allowing the connecting member 250 to rotatably connect with the positioning blocks 232. The number of positioning blocks 232 on each adjusting ring 231 corresponds to the number of second clamping rods 220, facilitating adjustment of the second clamping rods 220 by the second adjusting ring 231. The fixed rod 210 is connected to the threaded rod 110, and one side of the fixed rod 210... One end of the fixed rod 210 is connected to one end of the threaded rod 110, so that the extension direction of the axis of the fixed rod 210 is the same as the extension direction of the axis of the threaded rod 110. The second adjusting ring 231 on the fixed rod 210 facing the threaded rod 110 is threadedly connected to the fixed rod 210, thereby adjusting the opening angle of the second clamping rod 220. In order to keep the second clamping rod 220 clamping the pump body, a compression spring 260 is provided between the two adjusting rings 231. The compression spring 260 can abut against the two second adjusting rings 231. The compression spring 260 is sleeved on the outside of the fixed rod 210.

[0042] In summary, this application provides a water pump mechanical seal disassembly device, mainly including a sealing ring clamping device 100 and a pump body clamping device 200. In use, the pump body clamping device 200 is first connected to the sealing ring clamping device 100. The second clamping rod 220 on the pump body clamping device 200 is fixed to the pump body shell via a second adjusting member 230, keeping the sealing ring and pump body relatively stationary. The pump body is located within the second clamping opening 240 formed by the second clamping rod 220. In the sealing ring clamping device 100, by adjusting the first adjusting member 120, the abutment block 1312 of the clamping end 1311 on the first clamping rod 131 contacts and clamps the stationary ring end face, maintaining the stability of the object. After clamping the object, releasing the second clamping rod 220 of the pump body clamping device 200 allows the object to be removed, completing the above operation.

[0043] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
