Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection equipment technology, specifically to an internal plug and internal leakage detection machine. Background Technology

[0002] Blockages in refrigerator pipes (such as welding slag, oil blockages, and ice blockages) can obstruct refrigerant flow, reducing the heat exchange efficiency of the evaporator / condenser. Localized blockages in the capillary tube can directly lead to refrigeration failure. Blockages can create high-pressure stagnation points, potentially causing compressor overload and shortening its lifespan. Internal leaks can cause refrigerant to gradually leak out, leading to performance degradation. Therefore, detecting internal blockages and leaks in refrigerator refrigeration pipes is a critical quality control step in the production and maintenance of refrigeration equipment. Traditional methods, such as soapy water leak detection, rely on the extensive experience of inspectors, requiring significant manpower and offering poor accuracy. Modern testing equipment, such as ultrasonic + infrared combined detection, can reduce the time to 15 minutes, but its equipment cost is higher.

[0003] Therefore, there is a need for an internal leak detection machine that can improve detection accuracy, production efficiency, and detection cost. Utility Model Content

[0032] Example 1:

[0033] Please refer to Figure 1-5 This embodiment provides an internal plugging and internal leakage detection machine, including a frame assembly 10, an air circuit assembly 20, a data processing module 30 and an interaction component 40;

[0034] The frame assembly 10 mainly serves as a support and provides a support base for each component. It includes a support frame 11 and a worktable 12. The worktable 12 is horizontally fixed on the support frame 11. An inspection station is formed on the worktable 12, which is used to fix the workpiece to be inspected.

[0035] The air passage assembly 20 is fixed to the support frame 11. The air passage assembly 20 includes an air passage connector 21, which extends to the worktable 12. The air passage assembly 20 is connected to the workpiece to be inspected through the air passage connector 21.

[0036] The data processing module 30 is fixed to the support frame 11 and is electrically connected to the gas path assembly 20. It is used to acquire the detection data of the gas path assembly 20 and output the detection result based on the detection data.

[0037] The interactive component 40 is electrically connected to the data processing module 30, and the detection results are presented through the interactive component 40.

[0038] This embodiment detects internal blockages and leaks in a workpiece by fixing the workpiece to be tested at the testing station and connecting it to the gas path assembly 20 via a gas path connector 21. A constant flow rate of gas is introduced into the workpiece from the gas path assembly 20, and the pressure difference between the inlet and outlet is measured. Additionally, the workpiece is pressurized to 1.5 times the working pressure, and the pressure drop rate is measured. A data processing module 30 directly acquires the test data from the gas path assembly 20 and outputs the test results based on this data. The interactive component 40 provides a visual representation of the test results. This embodiment of the internal blockage and leakage detection machine features a simple structure, ease of use, low cost, and a balance between testing accuracy and production efficiency.

[0039] Specifically, the frame assembly 10 is a sheet metal frame composed of several profiles, and the bottom of the worktable 12 forms a mounting cavity 111. The surface of the mounting cavity 111 is covered with several protective plates, thereby making the mounting cavity 111 an independent space. The air passage assembly 20 is disposed in the mounting cavity 111 to avoid external interference during the detection process.

[0040] The frame assembly 10 also includes a door panel 13, which is hinged to the support frame 11. The mounting cavity 111 can be opened or closed by flipping the door panel 13. A locking element is also provided between the door panel 13 and the support frame 11 to lock the relative position between them. The openable and closable door panel 13 facilitates the maintenance of the internal components of the mounting cavity 111.

[0041] A mounting bracket 112 is formed on the top of the workbench 12, and the interactive component 40 is mounted above the workbench 12 via the mounting bracket 112. The mounting bracket 112 provides a mounting base for the interactive component 40, fixing the interactive component 40 at the visual height of the inspection personnel, which facilitates the control of the inspection process.

[0042] The gas path assembly 20 in this embodiment includes a gas path pipe 22 and a gas source 23. The gas path pipe 22 is a pipe with a diameter of 10 mm. Different pipe systems can have different colored coatings on the surface of the gas path pipe 22 for differentiation. The gas source 23 is a 10-liter gas storage tank, which provides a dry and clean detection medium and can buffer pressure fluctuations to improve detection accuracy.

[0043] The air source 23 is connected to the air connector 21 via the air pipe 22. The air pipe 22 is sequentially connected to a filter pressure reducing valve 24, a flow meter 26, and a pressure sensor from the air source 23 to the air connector 21. The filter pressure reducing valve 24 stabilizes the air source pressure to the required detection pressure, while removing particulate matter, moisture, oil mist, and ultrafine particles to prevent clogging of the capillary section.

[0044] Furthermore, a proportional valve 25 is provided between the filter pressure reducing valve 24 and the flow meter 26, and a pressure transmitter 27 is used as the pressure sensor. Through the cooperation of the proportional valve 25, the flow meter 26, and the pressure transmitter 27, high-precision flow and pressure control of the gas circuit system is achieved, improving detection accuracy.

[0045] The gas circuit assembly 20 also includes a first control valve 28 and a second control valve 29. The first control valve 28 is located between the gas source 23 and the filter pressure reducing valve 24. The second control valve 29 is located between the pressure transmitter 27 and the gas circuit connector 21. The gas circuit connector 21 can be configured with connection interfaces of different specifications. The second control valve 29 controls the opening and closing of each interface, so that this internal plug and internal leak detection machine can be compatible with the detection of pipelines of different specifications, thereby improving its practicality.

[0046] The interactive component 40 in this embodiment includes an industrial control computer 41 and an audible and visual alarm component 42. The industrial control computer 41 displays the detection data and results in real time, and the tri-color light and buzzer provide graded alarms for the detection results, thereby achieving an intuitive presentation of the detection results, helping the testing personnel to quickly judge the results and improve production efficiency.

[0047] Although certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0048] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
