[0034] In order to solve the problem that the efficiency of supercharger detection equipment in the prior art in detecting and solving surge faults is low, the present application provides a supercharger detection equipment.

[0035] like Figure 1 and Figure 2As shown, the supercharger detection equipment includes a workbench 10, an adjustment structure, a cache structure 20 and a detection device 30. The workbench 10 has a working surface for installing the part to be detected 1. The adjustment structure is arranged on the circulation part of the part to be detected 1, and the adjustment structure has a connecting position and a blocking position. When the adjustment structure is in the connecting position, the circulation part is connected to the outside world to release the gas in the part to be detected 1 to the outside world. When the adjustment structure is in the blocking position, the circulation part is not connected to the outside world. The cache structure 20 is arranged on the workbench 10, and the cache structure 20 is connected to the exhaust part of the part to be detected 1 to cache and discharge the gas discharged from the exhaust part. The detection device 30 is arranged on the part to be detected 1 to detect the vibration frequency and sound volume of the part to be detected 1, and send the detection result to the control device 40. The control device 40 controls the adjustment structure to switch between the connecting position and the blocking position according to the detection result.

[0036] Applying the technical solution of this embodiment, the workbench 10 of the supercharger detection equipment has a working surface for installing the part to be detected 1. The adjustment structure is arranged on the circulation part of the part to be detected 1, and the adjustment structure has a connection position and a blocking position. When the adjustment structure is in the connection position, the circulation part is connected to the outside world to release the gas in the part to be detected 1 to the outside world. When the adjustment structure is in the blocking position, the circulation part is not connected to the outside world. The cache structure 20 is arranged on the workbench 10, and the cache structure 20 is connected to the exhaust part of the part to be detected 1 to cache and discharge the gas discharged from the exhaust part. The detection device 30 is arranged on the part to be detected 1 to detect the vibration frequency and sound volume of the part to be detected 1, and send the detection result to the control device 40, and the control device 40 controls the adjustment structure to switch between the connection position and the blocking position according to the detection result. In this way, when the staff performs a performance test on the part to be detected 1, the detection device 30 arranged on the part to be detected 1 can monitor the vibration frequency and sound volume of the part to be detected 1 in real time during operation, so that the supercharger detection equipment can timely identify abnormal working conditions such as surge. Once a surge fault occurs in the detected part 1, the control device 40 will automatically control the adjustment structure to switch to the connected position according to the detection result, quickly reduce the pressure and gas flow in the supercharger, thereby alleviating the surge phenomenon of the detected part 1, avoiding damage to the detected part 1, ensuring the stable operation of the detected part 1, and realizing real-time adjustment and optimization of the operating state of the detected part 1 without manual intervention, thereby improving the detection efficiency and safety of the supercharger detection equipment, and further solving the problem of low efficiency of supercharger detection equipment in discovering and solving surge faults in the prior art. At the same time, the above-mentioned setting of the cache structure 20 can stabilize the gas pressure of the exhaust part, reduce the influence of exhaust fluctuations on the detection results, and thus improve the accuracy and reliability of the overall detection.

[0037] In this embodiment, the component to be detected 1 is a supercharger.

[0038] In this embodiment, the detection device 30 is disposed on the housing or the bearing seat of the supercharger to improve the detection accuracy.

[0039] In this embodiment, the supercharger detection device is further provided with an alarm device, which is connected to the control device 40. The control device 40 controls the alarm device to send out an alarm signal according to the detection result.

[0040] Specifically, the alarm device is one of an audible and visual alarm and a buzzer.

[0041] like Figure 1 and Figure 2 As shown, the cache structure 20 has a cache cavity 21, an air inlet 22 and an air outlet 23. The air inlet 22 and the air outlet 23 are both connected to the cache cavity 21, and the air inlet 22 is connected to the exhaust portion. The cache cavity 21 is used to cache the gas flowing in from the air inlet 22. The air outlet 23 is tubular, and the air outlet 23 is used to discharge the gas in the cache cavity 21. In this way, the cache structure 20 realizes the cache of the gas discharged from the to-be-detected part 1 through the cache cavity 21. After the gas discharged from the exhaust portion enters the cache cavity 21, it needs to fill the cache cavity 21 first and then be discharged from the air outlet 23, which stabilizes the gas pressure of the exhaust portion, avoids fluctuations in the gas discharge process of the exhaust portion, ensures the stability of gas discharge during the detection process of the to-be-detected part 1, and further improves the detection accuracy and detection reliability of the supercharger detection equipment. At the same time, the arrangement of the air outlet 23 enables the gas discharged from the cache cavity 21 to be discharged along a predetermined path, reduces the resistance and interference in the gas flow process, optimizes the flow characteristics of the gas, and further improves the detection accuracy and detection reliability of the supercharger detection equipment.

[0042] like Figure 1 and Figure 2 As shown, the supercharger detection equipment also includes a flow detection device 50 and a control valve 60. The flow detection device 50 is arranged on the gas outlet 23 to detect the flow of the gas in the gas outlet 23, and sends the detection data to the control device 40. The control valve 60 is arranged on the gas outlet 23, and the control valve 60 is connected to the control device 40. The control device 40 controls the start of the control valve 60 according to the detection data to control the flow of the gas in the gas outlet 23. In this way, the above-mentioned setting realizes the real-time monitoring function of the gas flow in the gas outlet 23 through the flow detection device 50, and improves the automation degree of the supercharger detection equipment. At the same time, the above-mentioned setting of the control valve 60 enables the control device 40 to control the start of the control valve 60 in real time according to the detection data of the flow monitoring device, thereby ensuring the precise control of the gas flow in the gas outlet 23, thereby ensuring the flow stability of the gas in the gas outlet 23, and further ensuring the stability of the exhaust process of the part to be detected 1. At the same time, the above arrangement can further reduce the flow rate of the gas in the test piece 1 when a surge fault occurs in the test piece 1, thereby further ensuring the operational stability of the test piece 1.

[0043] like Figure 1 and Figure 2 As shown, the supercharger detection device further includes a ventilation channel 70, which is disposed on the workbench 10. The ventilation channel 70 has an air inlet 73 and an air outlet 74. The ventilation channel 70 is connected to the part to be detected 1, so as to drive the external gas to flow through the part to be detected 1 from the air inlet 73 and then be discharged from the air outlet 74. In this way, the ventilation channel 70 realizes the smooth and orderly flow of gas through the part to be detected 1 through the air inlet 73 and the air outlet 74, optimizes the flow path and flow efficiency of the gas, reduces the vibration of the gas due to poor flow, and further ensures the operation stability of the part to be detected 1.

[0044] like Figure 1 and Figure 2 As shown, the ventilation channel 70 includes an air inlet channel 71 and an air outlet channel 72. One end of the air inlet channel 71 has an air inlet 73, and the other end of the air inlet channel 71 is connected to the part to be detected 1 to drive the external gas to flow from the air inlet 73 to the part to be detected 1. One end of the air outlet channel 72 is connected to the exhaust part, and the other end of the air outlet channel 72 has an air outlet 74, and the air outlet 74 is connected to the air inlet part 22 to discharge the gas in the part to be detected 1 to the air inlet part 22. In this way, the ventilation channel 70 realizes the external gas entering the part to be detected 1 through the air inlet channel 71, and realizes the discharge of the gas from the part to be detected 1 through the air outlet channel 72, thereby ensuring the smoothness and stability of gas circulation.

[0045] like Figure 1 and Figure 2 As shown, the supercharger detection device also includes a detection structure, which is arranged on the air inlet channel 71 and / or the air outlet channel 72 to detect the pressure and flow of the gas in the air inlet channel 71 and / or the air outlet channel 72, and send the detected values ​​to the control device 40. In this way, the above-mentioned arrangement realizes the real-time monitoring of the pressure and flow of the gas in the air inlet channel 71 and the air outlet channel 72, so that the control device 40 can evaluate the air intake performance of the air inlet channel 71 and the exhaust state of the part to be detected 1 according to the detected values, thereby dynamically adjusting the gas pressure and flow of the air inlet channel 71 and the air outlet channel 72, and further ensuring the operation stability of the part to be detected 1.

[0046] In this embodiment, both the air inlet passage 71 and the air outlet passage 72 are provided with detection structures.

[0047] In this embodiment, the detection structure includes a gas pressure sensor and a flow sensor.

[0048] like Figure 1 and Figure 2As shown, the detection device 30 includes a vibration detection structure and a sound detection structure. The vibration detection structure is arranged on the part to be detected to detect the vibration frequency of the part to be detected 1. The sound detection structure is arranged on the part to be detected to detect the sound volume of the part to be detected 1. In this way, the above-mentioned arrangement realizes the detection of the vibration frequency of the part to be detected 1 through the vibration detection structure, realizes the detection of the sound volume of the part to be detected 1 through the sound detection structure, realizes the real-time monitoring of various aspects of the part to be detected 1, improves the accuracy and efficiency of detecting surge failures of the part to be detected 1, further ensures the operating stability of the part to be detected 1, and also improves the detection reliability of the supercharger detection equipment.

[0049] In this embodiment, the vibration detection structure is an acceleration sensor.

[0050] Specifically, the acceleration sensor can capture the acceleration and vibration signals generated by the component to be detected 1 during operation, and provide data support for subsequent analysis and fault judgment.

[0051] In this embodiment, the sound detection structure is a noise sensor.

[0052] Specifically, the acceleration sensor is a MEMS sensor to detect the vibration frequency of the detected component 1 along the first preset direction, the second preset direction and the third preset direction.

[0053] Specifically, the first preset direction is a horizontal line direction, the second preset direction is a vertical line direction, and the third preset direction is a direction perpendicular to both the horizontal line direction and the vertical line direction.

[0054] like Figure 1 and Figure 2 As shown, the supercharger detection device further includes a lubrication structure 80, which is disposed on the workbench 10 and is in communication with the part to be detected 1, so as to drive the lubrication medium to flow from the lubrication structure 80 into the part to be detected 1. In this way, the above arrangement realizes the continuous and accurate supply of the lubrication medium to be detected through the lubrication structure 80, reduces the friction between the internal components of the part to be detected 1, reduces the wear of the part to be detected 1, avoids the failure of the part to be detected 1 due to insufficient lubrication, ensures the smooth operation of the part to be detected 1, and prolongs the service life of the part to be detected 1.

[0055] like Figure 1 and Figure 2As shown, the lubrication structure 80 includes a receiving portion, a pump body portion and a connecting portion. The receiving portion has a receiving cavity and a liquid outlet portion, the receiving cavity is connected to the liquid outlet portion, and the receiving cavity is used to store the lubricating medium. The connecting portion is arranged between the pump body portion and the part to be detected 1. The two ends of the pump body portion are respectively connected to the liquid outlet portion and the part to be detected 1 through the connecting portion. Alternatively, one end of the pump body portion is connected to one of the liquid outlet portion and the part to be detected 1, and the other end of the pump body portion is connected to the other of the liquid outlet portion and the part to be detected 1 through the connecting portion. In this way, the lubrication structure 80 realizes the storage of the lubricating medium through the receiving portion. At the same time, the above-mentioned setting of the pump body portion realizes the function of the lubrication structure 80 to drive the flow of the lubricating medium, while making the formation of the lubrication structure 80 simpler, reducing the production cost of the lubrication structure 80 and the processing difficulty of the staff. At the same time, the setting method of the connecting structure optimizes the flow path of the lubricating medium, reduces the flow resistance and turbulence, and ensures the operation stability of the lubricating medium.

[0056] like Figure 1 and Figure 2 As shown, the supercharger detection device also includes a protective structure 90, which is arranged on the workbench 10. The protective structure 90 has a protective cavity, and the to-be-detected part 1 is located in the protective cavity. In this way, the above arrangement, on the one hand, realizes the separation of the to-be-detected part 1 from the outside world through the protective structure 90, avoids the to-be-detected part 1 from being affected by the external environment, reduces the running smoothness of the to-be-detected part 1, and improves the running safety of the to-be-detected part 1. On the other hand, it also avoids the harm to the staff during the operation of the to-be-detected part 1, improves the safety of the supercharger detection equipment, and also improves the work safety of the staff.

[0057] Specifically, the process of the supercharger detection device when a surge fault occurs in the component to be detected 1 is as follows:

[0058] The acceleration sensor and noise sensor installed on the supercharger collect the vibration frequency and sound volume of the supercharger in real time, and transmit the detection results to the control device 40. The control device 40 converts the detection results into spectrum data after Fourier transformation, and analyzes the frequency characteristics and amplitude distribution of the supercharger.

[0059] At the same time, the data processing unit of the control device 40 analyzes the acquired data based on a preset algorithm to identify whether the supercharger has a surge fault. By analyzing the spectrum of the vibration signal, the main vibration frequency and amplitude of the supercharger during operation can be identified. If the vibration amplitude of certain specific frequencies increases abnormally, and the frequency is consistent with the natural frequency or surge characteristic frequency of the supercharger, it can be determined that the supercharger has surged. After that, the data processing unit immediately sends a fault signal to the controller, and the controller controls the adjustment structure to switch to the connected position to release the gas in the detection part 1.

[0060] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0061] The workbench of the supercharger detection equipment has a working surface for installing the part to be detected. The adjustment structure is arranged on the circulation part of the part to be detected, and the adjustment structure has a connecting position and a blocking position. When the adjustment structure is in the connecting position, the circulation part is connected to the outside world to release the gas in the part to be detected to the outside world. When the adjustment structure is in the blocking position, the circulation part is not connected to the outside world. The buffer structure is arranged on the workbench, and the buffer structure is connected to the exhaust part of the part to be detected to cache the gas discharged from the exhaust part and then discharge it. The detection device is arranged on the part to be detected to detect the vibration frequency and sound volume of the part to be detected, and send the detection result to the control device. The control device controls the adjustment structure to switch between the connecting position and the blocking position according to the detection result. In this way, when the staff performs a performance test on the part to be detected, the detection device arranged on the part to be detected can monitor the vibration frequency and sound volume of the part to be detected in real time during operation, so that the supercharger detection equipment can timely identify abnormal working conditions such as surge. Once a surge fault occurs in the part to be detected, the control device will automatically control the adjustment structure to switch to the connected position according to the detection result, quickly reduce the pressure and gas flow in the supercharger, thereby alleviating the surge phenomenon of the part to be detected, avoiding damage to the part to be detected, ensuring the stable operation of the part to be detected, and realizing real-time adjustment and optimization of the operating state of the part to be detected without manual intervention, thereby improving the detection efficiency and safety of the supercharger detection equipment, and further solving the problem of low efficiency of supercharger detection equipment in discovering and solving surge faults in the prior art. At the same time, the above-mentioned setting of the cache structure can stabilize the gas pressure of the exhaust part, reduce the influence of exhaust fluctuations on the detection results, and thus improve the accuracy and reliability of the overall detection.
