Description

Technical Field

[0001] This invention relates to the field of air compressor technology, and more specifically, to an air compressor testing device. Background Technology

[0002] With the continuous advancement of industrial technology, compressors play an indispensable role in industrial production, energy utilization, aerospace, medical equipment, and high-end manufacturing. This means that air compressors need continuous optimization design, and the optimization process requires performance testing. However, current performance testing mainly relies on manual testing, and some testing devices require multiple adjustments under different working environments, resulting in low testing efficiency. Summary of the Invention

[0003] This invention provides an air compressor testing device to solve the problem of low testing efficiency in existing testing devices.

[0004] To address the aforementioned problems, this invention provides an air compressor testing device, comprising a test pipeline, a detection device, an adjustment device, and a control device. The input end of the test pipeline is connected to the outlet of the air compressor. Both the detection device and the adjustment device are mounted on the test pipeline. The control device is electrically connected to both the detection device and the adjustment device. The detection device detects the parameters of the compressed air output by the air compressor and transmits the detected data to the control device. The control device determines whether the data detected by the detection device meets the test conditions. The control device controls the adjustment device to adjust the flow resistance within the test pipeline to simulate different operating conditions.

[0005] Furthermore, the regulating device includes a first regulating valve and a second regulating valve, both of which are installed in the test pipeline. The portion of the test pipeline between the first and second regulating valves is a pressure regulating pipeline. The control device is used to control the opening degree of the first and second regulating valves, thereby adjusting the flow resistance in the pressure regulating pipeline.

[0006] Furthermore, the detection device includes a flow detection module, which includes a flow sensor and a nozzle. Both the flow sensor and the nozzle are installed in the pressure regulating pipeline, and the flow sensor is used to detect the flow rate in the pressure regulating pipeline.

[0007] Furthermore, the detection device also includes a differential pressure detection module, which is installed on the pressure regulating pipeline. One end of the differential pressure detection module is connected to the input side of the flow detection module, and the other end of the differential pressure detection module is connected to the output side of the flow detection module. The differential pressure detection module is used to detect the pressure difference between the two sides of the flow detection module.

[0008] Furthermore, the air compressor testing device also includes a dryer, which is connected to the test pipeline. In the transport direction of the test pipeline, the dryer is located before the regulating device, and the dryer dries the compressed air output by the air compressor.

[0009] Furthermore, the testing device includes a first pressure detection module and a second pressure detection module. The first pressure detection module is installed on the test pipeline and located between the air compressor and the dryer. The second pressure detection module is installed on the test pipeline and located between the dryer and the regulating device. The first pressure detection module is used to detect the pressure of the compressed air output by the air compressor, and the second pressure detection module is used to detect the pressure of the compressed air after it has been dried by the dryer.

[0010] Furthermore, the testing device includes a temperature detection module, which is installed on the test pipeline. In the transport direction of the test pipeline, the temperature detection module is located before the regulating device. The temperature detection module is used to detect the temperature of the compressed air output by the air compressor.

[0011] Furthermore, the air compressor testing device also includes a safety valve, which is installed on the test pipeline. When the pressure in the test pipeline exceeds the set value, the safety valve opens to release the air in the test pipeline.

[0012] Furthermore, the air compressor testing device also includes a vent valve, which is installed on the test pipeline and electrically connected to the control device. After the test is completed, the control device controls the vent valve to open, so as to discharge the compressed air in the test pipeline.

[0013] Furthermore, the control device includes an industrial computer, a wireless communication module, an alarm module, and a remote terminal. The detection device, adjustment device, wireless communication module, and alarm module are all electrically connected to the industrial computer. When the industrial computer determines that the data detected by the detection device is abnormal, the alarm module issues an alarm message and transmits the alarm message to the remote terminal through the wireless communication module.

[0014] Furthermore, the air compressor testing device also includes a silencer, which is connected to the test pipeline. In the conveying direction of the test pipeline, the silencer is located after the adjustment device and at the output end of the test pipeline. The silencer is used to reduce the noise of the compressed air output from the output end.

[0015] By applying the technical solution of this invention, a detection device, an adjustment device, and a control device are installed on the test pipeline, integrating all the necessary sensor modules into the test pipeline, thus reducing the overall size of the device. The detection device can collect parameters such as pressure, flow rate, and temperature in real time. The control device automatically determines whether the test conditions are met based on the collected data. Since the air compressor operates in different working environments, each with different performance parameters, the control device can also control the adjustment device to change the pipeline flow resistance, simulating various operating conditions, thereby improving the accuracy and reliability of the test data. This allows for the judgment of test conditions, the collection of compressed air parameters, and the adjustment of flow resistance to be completed within the same pipeline, improving testing efficiency. Furthermore, the control device reduces manual operation steps, lowering the difficulty of using the test device and reducing human error. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1As shown, an embodiment of the present invention provides an air compressor testing device, including a test pipe 10, a detection device 20, an adjustment device 30, and a control device 40. The input end of the test pipe 10 is connected to the outlet of an air compressor 50. The detection device 20 and the adjustment device 30 are both mounted on the test pipe 10. The control device 40 is electrically connected to the detection device 20 and the adjustment device 30 respectively. The detection device 20 is used to detect the parameters of the compressed air output by the air compressor 50 and transmit the detected data to the control device 40. The control device 40 is used to determine whether the data detected by the detection device 20 meets the test conditions. The control device 40 controls the adjustment device 30 to adjust the flow resistance in the test pipe 10 to simulate different working conditions.

[0020] In this embodiment, by setting a detection device 20, an adjustment device 30, and a control device 40 on the test pipeline 10, all the necessary sensor modules are integrated into the test pipeline 10, reducing the overall size of the device. The detection device 20 can collect parameters such as pressure, flow rate, and temperature in real time. The control device 40 automatically determines whether the test conditions are met based on the collected data. Since the air compressor 50 operates in different working environments, and the performance parameters corresponding to each working environment are different, the control device 40 can also control the adjustment device to change the pipeline flow resistance, simulating various operating conditions, thereby improving the accuracy and reliability of the test data. This allows for the judgment of test conditions, the collection of compressed air parameters, and the adjustment of flow resistance to be completed within the same pipeline, improving test efficiency. Moreover, the control device 40 can reduce manual operation steps, reducing the difficulty of using the test device and human error. This air compressor testing device can be used to test air compressors such as magnetic levitation air compressors.

[0021] like Figure 1 As shown, the regulating device 30 includes a first regulating valve 31 and a second regulating valve 32. Both the first regulating valve 31 and the second regulating valve 32 are installed in the test pipeline 10. The part of the test pipeline 10 located between the first regulating valve 31 and the second regulating valve 32 is the pressure regulating pipeline 11. The control device 40 is used to control the opening degree of the first regulating valve 31 and the second regulating valve 32, thereby adjusting the flow resistance in the pressure regulating pipeline 11.

[0022] In this embodiment, the control device 40 can adjust the opening of the first regulating valve 31 and the second regulating valve 32 respectively, thereby controlling and adjusting the flow resistance in the pressure regulating pipeline 11, and thus better simulating the operating state of the air compressor 50 under different working conditions, improving the applicability and efficiency of the device in testing.

[0023] like Figure 1As shown, the detection device 20 includes a flow detection module 21, which includes a flow sensor and a nozzle. Both the flow sensor and the nozzle are installed in the pressure regulating pipeline 11. The flow sensor is used to detect the flow rate within the pressure regulating pipeline 11. This setup allows for real-time acquisition of flow data within the pressure regulating pipeline 11, and the acquired flow data can be instantly transmitted to the control device 40. The control device 40 then uses the data to more precisely control the opening of the first regulating valve 31 and the second regulating valve 32, achieving stable adjustment of the test conditions.

[0024] like Figure 1 As shown, the detection device 20 also includes a differential pressure detection module 22, which is installed on the pressure regulating pipeline 11. One end of the differential pressure detection module 22 is connected to the input side of the flow detection module, and the other end of the differential pressure detection module 22 is connected to the output side of the flow detection module. The differential pressure detection module 22 is used to detect the pressure difference between the two sides of the flow detection module.

[0025] In this embodiment, while the flow detection module 21 monitors the flow rate in the pressure regulating pipeline 11, the differential pressure detection module 22 can collect the differential pressure data across the flow detection module 21 in real time, thereby assisting in the calibration of the flow measurement results and improving the accuracy and reliability of flow detection. Furthermore, the differential pressure detection module 22 can promptly detect whether there is blockage, leakage, or abnormal flow resistance in the test pipeline 10, and coordinate with the control device 40 to adjust or issue warnings, enhancing the stability and safety of the testing process.

[0026] like Figure 1 As shown, the air compressor testing device also includes a dryer 60, which is connected to the test pipeline 10. In the conveying direction of the test pipeline 10, the dryer 60 is located before the regulating device 30. The dryer 60 dries the compressed air output from the air compressor 50, removing moisture before the compressed air enters the pressure regulating pipeline 11. This prevents humidity from adversely affecting test results such as flow rate, thereby improving the accuracy and reliability of the test data. Furthermore, the dried air reduces corrosion and scaling of components such as sensors caused by moisture, extending the service life of the testing device 20 and the regulating device 30, and reducing maintenance and replacement costs.

[0027] like Figure 1 As shown, the detection device 20 includes a first pressure detection module 23 and a second pressure detection module 24. The first pressure detection module 23 is installed on the test pipeline 10 and located between the air compressor 50 and the dryer 60. The second pressure detection module 24 is installed on the test pipeline 10 and located between the dryer 60 and the regulating device 30. The first pressure detection module 23 is used to detect the pressure of the compressed air output by the air compressor 50, and the second pressure detection module 24 is used to detect the pressure of the compressed air after it has been dried by the dryer 60.

[0028] In this embodiment, by setting the first pressure detection module 23 and the second pressure detection module 24 at different locations, the pressure of compressed air before and after drying can be detected in segments. This not only allows for accurate acquisition of the output pressure of the air compressor 50, but also reflects the real-time operating performance of the dryer 60. When an abnormal pressure difference is detected before and after the dryer 60, the control device 40 can promptly issue an early warning or implement protective measures to prevent safety hazards caused by equipment malfunctions.

[0029] The first pressure detection module 23 includes a first pressure sensor and a first pressure transmitter, and the second pressure detection module 24 includes a second pressure sensor and a second pressure transmitter. One end of the first pressure sensor is connected to the test pipeline 10, and the other end of the first pressure sensor is connected to the industrial control computer 41. One end of the second pressure sensor is connected to the test pipeline 10, and the other end of the second pressure sensor is connected to the industrial control computer 41. The first and second pressure sensors are used to detect the pressure of compressed air in the test pipeline 10, and the first and second pressure transmitters are used to convert the pressure signals detected by the first and second pressure sensors into electrical signals.

[0030] like Figure 1 As shown, the detection device 20 includes a temperature detection module 25, which is installed on the test pipeline 10, in the conveying direction of the test pipeline 10, before the regulating device 30. The temperature detection module 25 is used to detect the temperature of the compressed air output by the air compressor 50. This allows for real-time acquisition of temperature parameters before the compressed air enters the regulating device 30, and combines these parameters with those of pressure, flow rate, etc., to provide a more comprehensive evaluation of the operating performance of the air compressor 50. Simultaneously, when an abnormal increase in gas temperature is detected, the temperature detection module 25, in conjunction with the control device 40, can promptly issue an early warning or take protective measures to avoid safety hazards caused by overheating during the test.

[0031] like Figure 1 As shown, the air compressor testing device also includes a safety valve 70, which is installed on the test pipeline 10. When the pressure inside the test pipeline 10 exceeds a set value, the safety valve 70 opens to release the air inside the test pipeline 10. This prevents pipeline rupture or component damage caused by abnormal pressure increases during the test, thus improving the safety of the device. Simultaneously, the automatic pressure relief function of the safety valve 70 avoids damage to the regulating device, testing device, and other components under overpressure conditions, reducing the risk of equipment failure and protecting the safety of operators.

[0032] like Figure 1As shown, the air compressor testing device also includes a vent valve 80, which is installed on the test pipeline 10 and electrically connected to the control device 40. After the test is completed, the control device 40 controls the vent valve 80 to open, thereby releasing the compressed air from the test pipeline 10 and preventing safety hazards caused by long-term retention of compressed air in the test pipeline 10, thus improving the safety of the device. Furthermore, the automatic control of the vent valve 80 reduces manual venting operations, improving the automation level and ease of operation of the testing process. Timely venting of the compressed air from the test pipeline 10 also eliminates interference from residual air in the next round of testing.

[0033] like Figure 1 As shown, the control device 40 includes an industrial computer 41, a wireless communication module 42, an alarm module, and a remote terminal. The detection device 20, the adjustment device 30, the wireless communication module 42, and the alarm module are all electrically connected to the industrial computer 41. When the industrial computer 41 determines that the data detected by the detection device 20 is abnormal, the alarm module issues an alarm message and transmits the alarm message to the remote terminal through the wireless communication module 42. In this embodiment, by setting up the control device 40, not only can the intelligence and automation level of the testing process be improved, and the accuracy and reliability of the test data be guaranteed, but also timely warnings can be given in abnormal situations, enhancing the safety of the testing device and the air compressor under test.

[0034] like Figure 1 As shown, the air compressor testing device also includes a silencer 90, which is connected to the test pipeline 10. In the conveying direction of the test pipeline 10, the silencer 90 is located after the adjusting device 30 and at the output end of the test pipeline 10. The silencer 90 is used to reduce noise in the compressed air output from the output end. In this embodiment, by setting the silencer 90, noise pollution generated during the testing process can be reduced, the testing environment improved, and the working comfort of the operators enhanced.

[0036] In addition, the air compressor testing device in this application also includes a data acquisition module 26, which is used to transmit the acquired data to the industrial control computer 41.
