Abstract
Description
Technical Field
[0001] The present application relates to the technical field of compressor testing, and in particular to a compressor test bench with adjustable intake air temperature. Background Art
[0002] The compressor is a device that raises low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. The performance of the compressor is closely related to the temperature of the inhaled air and the exhaust temperature of the compressor. The temperature of the inhaled air is mainly related to the ambient temperature. At the same speed and compression ratio, the exhaust temperature of the compressor is mainly affected by the temperature of the gas inhaled into the compressor.
[0003] Currently, when testing the working performance of a compressor, the temperature of the gas inhaled by the compressor is the gas temperature in the test environment at that time, and the test environment temperature is less affected by the compressor. However, the compressor is usually used in a small space such as the bottom of a refrigerator. As the compressor continues to work, the ambient temperature of the compressor continues to rise, resulting in the working performance of the compressor obtained in the traditional test being only the performance result of the compressor under the test environment temperature. This result cannot represent the working performance of the compressor under actual conditions, which causes deviations in the test results of the compressor's working performance and is insufficient. Utility Model Content
[0004] In order to improve the problem of inaccurate compressor performance test results, the present application provides a compressor test bench with adjustable intake air temperature.
[0005] The present application provides a compressor test bench with adjustable intake air temperature, which adopts the following technical solution:
[0006] A compressor test bench with adjustable intake temperature comprises a test box with a hollow interior, a compressor is placed in the test box, an air inlet and an exhaust port are provided on the test box, a temperature sensor electrically connected to a control system is arranged in the test box, and an adjustment component is arranged on the test box, and the adjustment component can adjust the temperature in the test box.
[0007] By adopting the above technical solution, workers install the compressor to be tested in the test box, and then change the temperature in the test box by adjusting the components so that the compressor is at this temperature. The temperature value is fed back to the control system through the temperature sensor, and the compressor in the test box is subjected to multiple performance tests to detect the performance of the compressor at the corresponding temperature, thereby improving the accuracy of the compressor performance test results.
[0008] Optionally, the regulating component includes a heater electrically connected to a control system, and a through pipe is provided between an air outlet of the heater and an air inlet on the test box.
[0009] By adopting the above technical solution, workers start the heater through the control system. The hot air in the heater flows into the test box through the pipe, heating the gas in the test box, thereby simulating the effect of rising air temperature when the compressor works in a small space such as the bottom of a refrigerator. Through the constant feedback of the temperature sensor, the compressor can inhale gases of different temperatures, thereby making the performance test results of the compressor more accurate.
[0010] Optionally, a transfer box is provided at the air inlet on the test box body, the through pipe is connected to the transfer box, an air supply port is opened on the transfer box, and a filter screen is provided at the air supply port on the transfer box.
[0011] By adopting the above technical solution, when the air outlet of the heater blows air into the adapter box, the air in the external environment can enter the interior of the adapter box through the air supply port on the adapter box. The adapter box balances the air blown out by the heater, making the temperature of the air entering various parts of the test box more uniform, which is beneficial to improving the accuracy of the performance test results of the compressor at the corresponding temperature. At the same time, the filter plate is beneficial to reduce the possibility of impurities in the external air entering the test box, causing damage to the equipment in the test box.
[0012] Optionally, an air supply box is provided next to the test box, a blower electrically connected to a control system is provided on the air supply box, and a blower pipe is connected between the air supply box and the adapter box.
[0013] By adopting the above technical solution, when the next compressor needs to be tested, the worker starts the blower through the control system. The blower blows normal temperature air into the transfer box through the blower pipe. The normal temperature air in the transfer box flows into the test box, and the test air remaining in the test box is discharged, which is convenient for the next compressor to perform performance testing under different temperature conditions.
[0014] Optionally, an exhaust fan is provided at the exhaust port of the test box, and the exhaust fan is electrically connected to a control system.
[0015] By adopting the above technical solution, after the blower blows room temperature air into the test box through the blower pipe and the adapter box, the control system starts the exhaust fan, and the exhaust fan discharges the test air in the test box, which is beneficial to shorten the time required to discharge the residual test air in the test box and is beneficial to improving the efficiency of workers testing the compressor.
[0016] Optionally, an intermediate box communicating with the air inlet is disposed in the test box, a ventilation pipe is connected between the intermediate box and the air inlet end of the compressor, and the temperature sensor is disposed on the intermediate box.
[0017] By adopting the above technical solution, the space occupied by the gas at the test temperature is reduced while ensuring the gas volume required for the compressor performance test. This is conducive to workers quickly adjusting the gas at different temperatures. At the same time, the gas temperature value detected by the temperature sensor is more accurate, which is conducive to reducing the time required for workers to adjust the gas temperature and further improving the efficiency of workers' detection.
[0018] Optionally, the regulating component includes a refrigerator electrically connected to the control system, and a cold air duct is connected between the air outlet of the refrigerator and the adapter box.
[0019] By adopting the above technical solution, workers start the refrigerator through the control system, and the refrigerator supplies cold air to the adapter box through the cold air duct. The cold air in the adapter box is sucked into the air intake end of the compressor, thereby simulating the working performance of the compressor in a low temperature environment and further improving the accuracy of the compressor performance test results.
[0020] Optionally, the adapter box is provided with a spoiler motor electrically connected to the control system, and a spoiler shaft is coaxially arranged on the output shaft of the spoiler motor. The spoiler shaft rotates and passes into the adapter box, and spoiler blades are arranged on the spoiler shaft in the adapter box.
[0021] By adopting the above technical solution, when the refrigerator blows cold air into the adapter box, the control system starts the spoiler motor, and the spoiler motor drives the spoiler blades to rotate through the spoiler shaft. The rotation of the spoiler blades makes the air temperature in the adapter box gradually evenly mixed, thereby improving the accuracy of the performance test results of the compressor when inhaling at this temperature.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The worker installs the compressor to be tested in the test box, and then changes the temperature in the test box by adjusting the components, so that the compressor is at this temperature. The temperature value is fed back to the control system through the temperature sensor, and the compressor in the test box is tested multiple times to detect the performance of the compressor at the corresponding temperature, so as to improve the accuracy of the compressor performance test results;
[0024] 2. The worker starts the heater through the control system. The hot air in the heater flows into the test box through the pipe, heating the gas in the test box, thereby simulating the effect of the air temperature rising when the compressor works in a small space such as the bottom of the refrigerator. Through the real-time feedback of the temperature sensor, the compressor can inhale gas at different temperatures, making the performance test results of the compressor more accurate;
[0025] 3. On the premise of ensuring the gas volume required for compressor performance testing, reducing the space occupied by the gas at the test temperature is conducive to workers quickly adjusting the gas at different temperatures. At the same time, the gas temperature value detected by the temperature sensor is more accurate, which is conducive to reducing the time required for workers to adjust the gas temperature and further improving the efficiency of workers' testing.

[0035] Reference Figure 1 and Figure 2An adjustment component 6 is arranged on the test box 2, and the adjustment component 6 can adjust the temperature in the test box 2. The adjustment component 6 includes a heating machine 61 arranged next to the test box 2 and electrically connected to the control system. A transfer box 7 is bolted to the air inlet 3 outside the test box 2, and a through pipe 62 is connected between the air outlet of the heater 61 and the transfer box 7. An air supply port 8 is opened on the transfer box 7, and a filter screen plate 9 is bolted to the air supply port 8 on the transfer box 7.
[0036] Reference Figure 1 and Figure 2 An air supply box 10 is arranged next to the test box 2, and a plurality of blowers 11 electrically connected to the control system are bolted to the top of the air supply box 10. Air inlet holes 19 are opened between the inner and outer walls around the air supply box 10, and a blower pipe 12 is connected between the air supply box 10 and the adapter box 7. An intermediate box 14 connected to the air inlet 3 is bolted to the inner wall of the test box 2, and a ventilation pipe 15 is connected between the intermediate box 14 and the air inlet end of the compressor 1, and the temperature sensor 5 is bolted to the intermediate box 14.
[0037] The implementation principle of Example 1 is as follows: the worker first installs the compressor 1 to be tested in the test box 2, and uses the ventilation pipe 15 to connect the intermediate box 14 with the air inlet end of the compressor 1, and then the worker starts the heater 61 through the control system, and the hot air in the heater 61 flows into the adapter box 7 through the ventilation pipe 62, and then the control system starts the blower 11 on the air supply box 10, and the blower 11 blows normal temperature air into the adapter box 7 through the blower pipe 12, and the mixed air in the adapter box 7 flows into the intermediate box 14 through the air inlet 3 on the test box 2.
[0038] The temperature sensor 5 on the intermediate box 14 feeds back the gas temperature to the control system until the temperature in the intermediate box 14 reaches the test temperature, and then the performance of the compressor 1 is tested. After that, the worker adjusts the output gas content of the blower 11 and the heater 61 and adjusts the gas temperature in the adapter box 7, thereby changing the temperature value of the gas in the intermediate box 14, and then performs performance testing on the compressor 1 under different gas temperature conditions, so as to improve the accuracy of the performance test results of the compressor 1.
