Description

Technical Field

[0002] Turbochargers are a commonly used type of automotive engine supercharger. They use the engine exhaust to drive the exhaust turbine in the turbine to rotate, thereby driving the coaxial compressor impeller to rotate. The impeller presses the air sent from the air filter duct and pressurizes it into the cylinder, thereby improving the charging efficiency and optimizing the engine's combustion process. However, the working environment of the turbocharger is very harsh, and it needs to withstand the loads brought by high temperature, high pressure and high-speed rotation, so its performance and reliability requirements are extremely high. In the research and development, production and maintenance of turbochargers, it is very important to accurately detect and test them.

[0003] In order to ensure the performance of turbochargers, test benches for testing turbochargers have begun to appear. Such test benches can test the pressure, intake and exhaust flow, temperature, etc. of the turbocharger to ensure that the turbochargers maintained and shipped have appropriate performance parameters. However, when the turbocharger is tested, the intake and exhaust will vibrate, and the change in the frequency of the vibration may be accompanied by changes in the internal structure of the turbocharger. Furthermore, the turbocharger may need to withstand different temperature conditions during use.

[0025] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0027] In addition, in the description of the present application, it should be understood that the orientations or positional relationships indicated by the terms "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0028] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] In the present application, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0030] like Figure 1 and Figure 2 As shown, the present application provides a turbocharger 30 detection test bench, which includes a screw fan 10 and a test bench 20. The test bench 20 is provided with a turbocharger 30, an air intake passage 11 is provided between the screw fan and the turbocharger 30, a first constant temperature component 12 is provided at the air intake passage 11, and the test bench 20 is provided with an amplitude detection component 21 and a speed detection component 22.

[0031] Among them, Figure 1 As shown, the first thermostatic component 12 includes a gas heater 121 and a cooling pipe 122 . The gas heater 121 and the cooling pipe 122 are sequentially connected along the air intake direction. A plurality of refrigerant pipelines 272 are provided on the inner wall of the cooling pipe 122 .

[0032] It can be understood that by arranging the gas heater 121 at the air intake passage 11, the airflow can be heated when the screw fan 10 supplies the airflow to the interior of the turbocharger 30, so that the turbocharger 30 can reach a working environment close to that in normal operation, thereby more accurately simulating the actual working environment and obtaining more accurate detection parameters.

[0033] In addition, the present application replaces the traditional engine and fan by setting a screw fan 10. The screw fan 10 has a high gas compression efficiency. The gas is compressed by the rotation of the screw. Its unique internal lubrication system can ensure the long-term stable operation of the machine while reducing energy consumption. This high-efficiency and energy-saving feature enables the use of the screw fan 10 in the turbocharger 30 test bench to significantly reduce energy consumption. In addition, the screw fan 10 adopts a closed design to effectively prevent dust and debris from entering, ensuring the long-term stable operation of the machine. This feature is particularly important in the turbocharger 30 test bench, because the test bench may need to operate in a harsh environment, and the screw fan 10 can withstand the influence of these environments.

[0034] Furthermore, the present application sets a cooling pipe 122 behind the gas heater 121. On the one hand, the cooling pipe 122 can be used to perform more detailed temperature regulation to reduce the problem of overtemperature. On the other hand, due to the needs of the working environment, the turbocharger 30 may need to work in a colder environment. The setting of the cooling pipe 122 can provide a certain degree of cold air, further improving the detection range of the turbocharger 30 detection test bench, thereby further improving the accuracy of the detection.

[0035] As a preferred implementation of the present application, Figure 2 As shown, the test platform 20 includes a mounting platform body 23 and an operation box 24 that wraps the mounting platform body 23 . The operation box 24 is provided with an opening and closing door 241 . The mounting platform body 23 is provided with a turbocharger 30 .

[0036] It should be noted that if Figure 2 As shown, in order to reduce the occupied space and facilitate the opening and closing of the opening and closing door 241, the opening and closing door 241 can be set as a sliding door structure, and a transparent observation window can be opened in the opening and closing door 241.

[0037] When conducting the test, the opening and closing door 241 is first opened, and the turbocharger 30 is positioned at the mounting table, and the various pipelines of the turbocharger 30 are connected, and then the opening and closing door 241 is closed, and the screw fan 10 is turned on. The screw fan 10 drives the turbocharger 30 to work through the intake passage 11. By setting the first constant temperature component 12 at the intake passage 11, the turbocharger 30 can simulate the action at different working temperatures according to the needs, and then obtain the test parameters of the turbocharger 30 at different temperatures, so as to improve the accuracy and range of the detection; in addition, by setting the amplitude detection part 21, the vibration of the turbocharger 30 can be monitored in real time when the turbocharger 30 is conducting the detection test, so as to judge whether there is a problem with the turbocharger 30 by the frequency of vibration, thereby improving the accuracy of the detection; further, by setting the speed detection part 22, the real-time speed of the turbocharger 30 is detected, and it is further judged whether the turbocharger 30 has problems such as jamming.

[0038] Optionally, the air intake passage 11 is provided with a pressure sensor 13 and a temperature sensor 14 to determine the pressure change and temperature change between the screw fan 10 and the turbocharger 30 in real time, thereby further improving the detection value range and detection accuracy.

[0039] As a preferred embodiment of the present application, a temperature sensing component 14 and a heat-insulating layer 25 are provided on the inner wall of the operating box 24 , and a refrigerant pipeline 272 is provided inside the heat-insulating layer 25 .

[0040] like Figure 2 As shown, a plurality of temperature sensing components 14 can be provided, and the plurality of temperature sensing components 14 can be respectively arranged at the four corners of the inner wall of the operation box 24, and protrude toward the space inside the operation box 24 to comprehensively judge the real-time temperature inside the operation box 24. The insulation layer 25 can be arranged inside the inner wall of the operation box 24, which can absorb the internal temperature and reduce the temperature loss, thereby ensuring that the temperature inside the operation box 24 can be maintained at the temperature required by the test for a long time; furthermore, the setting of the refrigerant pipeline 272 can also adjust the temperature in real time. After the test, the cooling inside the operation box 24 can be accelerated to ensure the subsequent disassembly and assembly. At the same time, adaptive temperature adjustment can also be performed to ensure that the temperature is always within appropriate parameters.

[0041] Furthermore, if Figure 2 As shown, the detection platform 20 is provided with a positioning member 26, and the amplitude detection member 21 is arranged on the positioning member 26. The positioning member 26 can adopt a four-corner clamping structure, and the surface of the detection platform 20 is provided with four slideways arranged in a cross shape. Positioning blocks are slidably provided on the surface of each slideway, and the four positioning blocks move toward each other, so that the turbocharger 30 is fixed by squeezing the four positioning blocks toward the center, thereby improving the fixing effect of the turbocharger 30.

[0042] In addition, by setting the amplitude detection member 21 at the positioning member 26, since the turbocharger 30 will inevitably vibrate due to operation during the test and can drive the positioning member 26 to vibrate to a certain extent, setting the amplitude detection member 21 here can simulate the vibration of the fixed structure driven by the turbocharger 30 during actual use, thereby improving the accuracy of the detection.

[0043] As a preferred implementation of the present application, Figure 2 As shown, a second constant temperature component 27 is disposed on the inner wall of the testing platform 20 , and the second constant temperature component 27 includes an electric heating plate 271 and a refrigerant pipeline 272 .

[0044] It can be understood that the electric heating plate 271 can be set inside the operating box 24, and should be set on the outside of the insulation layer 25, so as to further regulate the internal temperature. It can not only make the turbocharger 30 in a suitable working environment for detection, but also ensure that the internal lubricating oil is in a suitable working environment through temperature control, improve the stability of work and the accuracy of detection, and can lock the temperature through the insulation layer 25 to reduce temperature leakage.

[0045] Furthermore, the inner wall of the operation box 24 is provided with a sound insulation layer 28, and the sound insulation layer 28 can be wrapped on the outermost layer of the inner wall of the operation box 24 to reduce the noise generated by the vibration of the detection supercharger, thereby providing a good working environment for the user.

[0046] As a preferred implementation of the present application, Figure 2 As shown, the test bench 20 also includes a touch control cabinet 29, and the surface of the control cabinet can be provided with adjustment buttons and a control panel. The adjustment buttons can adjust the temperature changes and the start and stop of the turbocharger 30 test in real time. The control panel is provided with a display screen, which can detect the changes of various data in real time for recording and real-time regulation.

[0047] Of course, the structures referred to in the drawings of this application are all rough structural diagrams. In actual products, an outer shell structure must be provided to protect and cover various positions to ensure the safety and reliability of internal equipment. A specific description will not be given here.

[0048] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0049] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0050] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
