DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The existing pump body main shaft cannot be detected in time when it is offset, which causes wear of the outer shell of the pump body and shortens the service life.

[0021] In view of this, a boiler pump body is provided. Through the cooperation between the spring, the square shell and the round block, it is possible to monitor whether the main shaft is laterally deviated, thereby solving the problem that the existing pump body main shaft cannot be detected in time when it is offset, which causes wear of the outer shell of the pump body and shortens the service life.

[0022] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and appropriate control units and encoders should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principles and processes, and no longer explains the electrical control.

[0023] Embodiment 1: Figure 1 , 2 As can be seen from Figures 4, a boiler pump body comprises a bottom plate 2, a body 1 is mounted on the top of the bottom plate 2, the inner side of the body 1 is rotatably connected to a main shaft 5 through a bearing 19, the main shaft 5 can rotate through the bearing, a monitoring mechanism is arranged inside the body 1, the monitoring mechanism comprises a square shell 14, a spring 3, a plate 16, a straight rod 17, a pressure sensor 15 and a control unit 20, the outer side of the square shell 14 is fixedly connected to the inner side of the body 1, the inner side of the square shell 14 is fixedly connected to the plate 16 through the spring 3, the bottom of the plate 16 is fixedly connected to the straight rod 17, the outer side of the straight rod 17 is movably connected to the bottom through hole of the square shell 14, the top of the plate 16 is fitted with a pressure sensor 15, the model of the pressure sensor 15 is not limited, a control unit 20 fixed to the inner side of the body 1 is arranged on one side of the square shell 14, the model of the control unit 20 is not limited, the square shell 14 and other structures are equidistantly distributed with the center of the main shaft 5 as the reference, and the specific number is not limited;

[0024] In the specific implementation process, it is worth pointing out that through the cooperation between the straight rod 17, the pressure sensor 15 and the control unit 20, the monitoring of whether the main shaft 5 is lateral deflected is realized, which solves the problem that the existing pump body main shaft 5 cannot be detected in time when it is offset, thereby causing wear of the outer shell of the pump body and shortening the service life;

[0025] Furthermore, the bottom groove of the straight rod 17 is movably connected to a round block 18, and the bottom of the round block 18 fits with the outer side of the main shaft 5;

[0026] In the specific implementation process, it is worth pointing out that the round block 18 can rotate freely in the bottom groove of the straight rod 17, and the device can drive the round block 18 to always fit with the outer side of the main shaft 5 by relying on the elastic deformation of the spring 3;

[0027] Specifically, when the boiler pump body is used, when the main shaft 5 is offset, it can drive the round block 18 and the straight rod 17 on one side to move. When the straight rod 17 moves, it drives the plate 16 to press the pressure sensor 15. The value of the pressure sensor 15 changes and sends a signal to the control unit 20. The control unit 20 can transmit the information to the external control console for reminder, and then inspect the main shaft 5.

The front surfaces of the first annular plate 7 and the second annular plate 8 are fixed with convex blocks 9 that fit each other. The inner sides of the two convex blocks 9 are fixedly connected by bolts 10.

[0029] In the specific implementation process, it is worth pointing out that the user can fix the second annular plate 8 to the first annular plate 7 by means of bolts 10;

[0030] Furthermore, two circular plates 11 that fit each other are fixedly connected to the inner sides of the outer walls of the straight tube 6 and the tube body 4, and two first sealing rings 12 are installed on the inner sides of the two circular plates 11;

[0031] In the specific implementation process, it is worth pointing out that the first sealing ring 12 ensures the sealing between the two circular plates 11;

[0032] Furthermore, a second sealing ring 13 is installed on the outer sides of the two circular plates 11, and the outer sides of the second sealing ring 13 are in contact with the inner sides of the first annular plate 7 and the second annular plate 8;

[0033] In the specific implementation process, it is worth pointing out that the second sealing ring 13 improves the sealing performance of the contact position between the first annular plate 7 and the second annular plate 8, forming two seals in total;

[0034] Specifically, on the basis of the above-mentioned first embodiment, the cooperation among the tube body 4, the first annular plate 7 and the first sealing ring 12 ensures the sealing of the connection position between the pump body and the pipeline, thereby avoiding leakage.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".
