Description

Technical Field

[0001] This utility model relates to the field of heat exchange module diagnostic technology, specifically a fault diagnosis device for heat exchange modules. Background Technology

[0002] A heat exchanger is an energy-saving device that facilitates heat transfer between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, bringing the fluid temperature to the specified parameters to meet process requirements. It is also a key component for improving energy efficiency. The heat exchanger industry encompasses nearly 30 sectors, including HVAC, pressure vessels, wastewater treatment equipment, chemicals, and petroleum, forming interconnected industrial chains. Internally, heat exchangers contain heat exchange modules, primarily tubular structures. When these modules malfunction, diagnostic devices are required for diagnosis.

[0003] During the diagnostic process, if tiny air bubbles appear at the bottom of the heat exchange module, they are difficult to observe inside the diagnostic chamber, which can easily lead to erroneous diagnostic results and affect the actual quality of the heat exchange module. Therefore, a fault diagnosis device for heat exchange modules is proposed to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a fault diagnosis device for heat exchange modules to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fault diagnosis device for a heat exchange module, including a box structure, the box structure including a diagnostic box, a support base fixedly installed on the bottom wall of the diagnostic box, a heat exchange module to be tested installed on the top of the support base, a water outlet opened on the right side of the diagnostic box, and a positioning and rotating structure installed inside the diagnostic box.

[0006] The positioning and rotating structure includes a first motor fixedly connected to the left side of the diagnostic box. The shaft of the first motor passes through the side wall of the diagnostic box and is connected to a threaded rod. The outer side of the threaded rod has two sections of external threads in opposite directions. The outer side of the threaded rod is threadedly connected to two first positioning plates and a second positioning plate through the two sections of external threads. A rotating connecting seat is rotatably provided on the opposite side of the first positioning plate and the second positioning plate. A second motor is fixedly connected to the other side of the second positioning plate. The shaft of the second motor passes through the second positioning plate and is fixedly connected to the rotating connecting seat.

[0007] Preferably, both ends of the heat exchange module under test are fixedly provided with flanges, and the heat exchange module under test is fixedly connected to the two rotating connecting seats by fixing bolts and the flanges.

[0008] By setting up flanges and fixing bolts, the heat exchange module under test can be fixedly connected to the two rotating connecting seats. The fixing bolts ensure the stability of the heat exchange module under test body during operation of the positioning and rotating structure.

[0009] Preferably, an air inlet pipe is provided through the first positioning plate, one end of which is connected to the heat exchange module to be tested, and the other end of which passes through the diagnostic box.

[0010] By connecting the air inlet pipe to the heat exchange module under test, the air supply to the heat exchange module under test is not affected by the positioning and rotating structure, thus improving air intake efficiency and diagnostic quality.

[0011] Preferably, a guide rod is fixedly provided between the inner walls of the diagnostic box, and the guide rod is slidably connected to both the first positioning plate and the second positioning plate.

[0012] By setting guide rods, the movement paths of the first and second positioning plates can be limited, preventing changes in the movement paths of the first and second positioning plates during the operation of the positioning rotation structure, which would cause positional deviations and affect the positioning effect and accuracy.

[0013] Preferably, the diagnostic box has an observation glass on its outer side.

[0014] By installing an observation glass on the outside of the diagnostic chamber, it is easier for operators to observe the internal environment of the diagnostic chamber when diagnosing the heat exchange module under test, thereby improving diagnostic efficiency and quality.

[0015] Preferably, the first motor is fixedly connected to the left side of the diagnostic box via a motor mount.

[0016] The first motor is fixed in place by a motor mount, which ensures the stability of the first motor during operation.

[0017] Compared with the prior art, this utility model provides a fault diagnosis device for heat exchange modules, which has the following beneficial effects:

[0018] 1. The fault diagnosis device for this heat exchange module, through the setting of a positioning rotation structure, allows the first motor to be started after the heat exchange module under test is placed on the support base. The threaded rod begins to rotate, causing the first positioning plate and the second positioning plate to move relative to each other. This brings the rotating connecting seat into contact with the heat exchange module under test, allowing for positioning operations on heat exchange modules of different lengths. After the heat exchange module under test is fixed and sealed, water is added to the diagnostic chamber to submerge the heat exchange module under test. At the same time, the air inlet pipe is connected to an external air pump, and the air pump is started to inflate the heat exchange module under test. Then, the second motor is started, driving the heat exchange module under test to rotate. This allows for the precise observation of air bubbles emerging from various positions on the outer wall of the heat exchange module under test, improving the diagnostic accuracy and efficiency of the diagnostic equipment and ensuring the quality of the heat exchange module.

[0019] 2. The fault diagnosis device for this heat exchange module uses a flange and fixing bolts to fix the heat exchange module under test to the rotating connecting seat, thereby ensuring the stability of the heat exchange module under test during rotation and further ensuring the accuracy of diagnosis.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3The present invention provides the following technical solution: a fault diagnosis device for a heat exchange module, including a box structure 1, the box structure 1 including a diagnostic box 11, a support base 12 fixedly installed on the bottom wall of the diagnostic box 11, a heat exchange module 13 to be tested installed on the top of the support base 12, a water outlet 14 opened on the right side of the diagnostic box 11, and a positioning and rotating structure 2 installed inside the diagnostic box 11.

[0026] The positioning and rotating structure 2 includes a first motor 21 fixedly connected to the left side of the diagnostic box 11. The shaft of the first motor 21 passes through the side wall of the diagnostic box 11 and is connected to a threaded rod 22. The outer side of the threaded rod 22 has two external threads in opposite directions. The outer side of the threaded rod 22 is threadedly connected to two first positioning plates 23 and second positioning plates 24 through the two external threads. A rotating connecting seat 25 is rotatably provided on the opposite side of the first positioning plate 23 and the second positioning plate 24. A second motor 26 is fixedly connected to the other side of the second positioning plate 24. The shaft of the second motor 26 passes through the second positioning plate 24 and is fixedly connected to the rotating connecting seat 25.

[0027] Through the above technical solution, by setting the positioning and rotating structure 2, after the heat exchange module 13 to be tested is placed on the support base 12, the first motor 21 is started, and the threaded rod 22 begins to rotate, thereby causing the first positioning plate 23 and the second positioning plate 24 to move relative to each other, so that the rotating connecting seat 25 contacts the heat exchange module 13 to be tested, and positioning operations are performed on heat exchange modules 13 of different lengths. After the heat exchange module 13 to be tested is fixed and sealed, water is added to the diagnostic box 11 to flood the heat exchange module 13 to be tested. At the same time, the air inlet pipe 17 is connected to the external air pump, and the air pump is started to inflate the heat exchange module 13 to be tested. Then the second motor 26 is started, and the second motor 26 drives the heat exchange module 13 to be tested to rotate, so that the bubbles emerging from various positions on the outer wall of the heat exchange module 13 to be tested can be accurately observed, improving the diagnostic accuracy and efficiency of the diagnostic equipment and ensuring the quality of the heat exchange module.

[0028] Specifically, both ends of the heat exchange module 13 under test are fixedly equipped with flanges 15, and the heat exchange module 13 under test is fixedly connected to two rotating connecting seats 25 by fixing bolts 16 and flanges 15.

[0029] Through the above technical solution, by setting the flange 15 and fixing bolts 16, the heat exchange module 13 under test can be fixedly connected to the two rotating connecting seats 25. The fixing is achieved by multiple fixing bolts 16, which ensures the stability of the heat exchange module 13 under test when the positioning and rotating structure 2 is working. By setting the flange 15 and fixing bolts 16, the heat exchange module 13 under test is fixedly connected to the rotating connecting seat 25 by the fixing bolts 16, thereby ensuring the stability of the heat exchange module 13 under test when rotating, and further ensuring the diagnostic accuracy.

[0030] Specifically, an air inlet pipe 17 is installed inside the first positioning plate 23. One end of the air inlet pipe 17 is connected to the heat exchange module 13 to be tested, and the other end passes through the diagnostic box 11.

[0031] By using the above technical solution, and by connecting the air inlet pipe 17 to the heat exchange module 13 under test, it is ensured that the air inlet pipe 17 is not affected by the positioning and rotating structure 2 when the heat exchange module 13 under test is ventilated, thereby improving the air intake efficiency and diagnostic quality.

[0032] Specifically, a guide rod 18 is fixedly installed between the inner walls of the diagnostic box 11, and the guide rod 18 is slidably connected to the first positioning plate 23 and the second positioning plate 24.

[0033] By using the above technical solution, the guide rod 18 can limit the movement path of the first positioning plate 23 and the second positioning plate 24, thus preventing the movement path of the first positioning plate 23 and the second positioning plate 24 from changing during the operation of the positioning rotation structure 2, which would cause positional deviation and affect the positioning effect and positioning accuracy.

[0034] Specifically, the diagnostic box 11 has an observation glass 19 on its outside.

[0035] By using the above technical solution, by setting an observation glass 19 on the outside of the diagnostic box 11, it is more convenient for operators to observe the internal environment of the diagnostic box 11 when diagnosing the heat exchange module 13 under test, thereby improving diagnostic efficiency and diagnostic quality.

[0036] Specifically, the first motor 21 is fixedly connected to the left side of the diagnostic box 11 via a motor mount.

[0037] The above technical solution ensures the stability of the first motor 21 during operation by fixing the first motor 21 with the motor mount.

[0038] In use, after placing the heat exchange module 13 to be tested on the support base 12, the first motor 21 is started, and the threaded rod 22 begins to rotate, thereby causing the first positioning plate 23 and the second positioning plate 24 to move relative to each other, so that the rotating connecting seat 25 contacts the heat exchange module 13 to be tested. Positioning operations are performed on heat exchange modules 13 of different lengths. After the heat exchange module 13 to be tested is fixed and sealed to the rotating connecting seat 25 by the flange 15 and the fixing bolts 16, water is added to the diagnostic box 11 to flood the heat exchange module 13 to be tested. At the same time, the air inlet pipe 17 is connected to the external air pump, and the air pump is started to inflate the heat exchange module 13 to be tested. Then the second motor 26 is started, and the second motor 26 drives the heat exchange module 13 to rotate, so that the bubbles emerging from various positions on the outer wall of the heat exchange module 13 to be tested can be accurately observed, thereby improving the diagnostic accuracy and efficiency of the diagnostic equipment.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
