DETAILED DESCRIPTION

[0019] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0021] A compressor testing system and testing method provided in an embodiment of the present application are exemplarily described below with reference to the accompanying drawings.

[0022] Figure 1 A schematic diagram of the structure of a compressor test system provided in an embodiment of the present application. The compressor test system includes: The air extraction component 100 is connected to the air outlet 3 of the compressor 2 .

[0023] The gas injection assembly 200 is connected to the gas inlet 24 of the compressor 2 .

[0024] The air extraction component 100 is used to extract air from the compressor 2 , and the gas injection component 200 can be used to inject test gas into the compressor 2 .

[0025] The compressor test system also includes: The test assembly 300 is used to test the working parameters of the compressor 2 .

[0026] Specifically, the air extraction component 100 can perform an air extraction operation on the compressor 2, such as a vacuum operation, or when the air pressure in the compressor 2 is too high, extract some gas to reduce the air pressure in the compressor 2 to avoid damage to the compressor 2 due to excessive air pressure. Figure 1As shown, the vacuum assembly 100 may include a vacuum pump 21 and a vacuum pipeline 20, and the vacuum pump 21 may be connected to the compressor 2 through the vacuum pipeline 20. Among them, the vacuum pump 21 may be a vacuum pump, and its function is to discharge the original gas in the compressor 2 and the related pipelines connected thereto, for example, completely empty them, to ensure that the compressor 2 will not be disturbed by the original gas during the test. The gas injection assembly 200 is used to inject test gas into the compressor 2, for example, when the compressor 2 is in a vacuum state, inject test gas into it. The test gas can be the working gas of the compressor 2, that is, the gas inside the compressor 2 under normal use. Other types of simulated gases can also be used. The embodiment of the present application does not limit this, and it can be selected according to actual needs.

[0027] After the interior of the compressor 2 is filled with the test gas, the compressor 2 can be controlled to run, and the working parameters of the compressor 2 can be monitored by the test component 300 to detect whether the compressor 2 to be tested is qualified.

[0028] To sum up, under the action of the vacuum assembly 100 and the gas injection assembly 200, the compressor 2 can be placed in a state that is completely identical to normal operation, thereby being able to more realistically reflect the working scene of the compressor 2 and more accurately determine whether the compressor 2 is qualified.

[0029] Among them, the air extraction component 100 can perform air extraction operation on the compressor 2 and the pipeline to ensure the gas injection effect and avoid mixing gas media other than the test gas. The test gas can also be extracted from the compressor 2 and the pipeline to avoid safety and environmental pollution problems; further, the air extraction operation of the air extraction component 100 can also be used to flush the compressor 2 and the pipeline to avoid the residue of the test gas. The effect of the air extraction component 100 is also explained in some subsequent embodiments.

[0030] Continue reading Figure 1 , in some embodiments, a gas storage component 400 is also included.

[0031] The gas storage component 400 is connected to the gas extraction component 100 .

[0032] The gas extraction assembly 100 is also used to extract the test gas in the compressor 2 to the gas storage assembly 400 .

[0033] Specifically, some of the test gases are harmful gases, so the embodiment of the present application also provides a gas storage component 400. After the test is completed, all the test gases can be extracted and properly stored or processed to avoid the pollution of the test gas to the environment, wherein the gas storage component 400 can be a gas tank. In the embodiment of the present application, the gas extracted into the gas storage component 400 by the exhaust component 100 will not be recycled into the compressor test system, that is, the gas storage component 400 is only used to store the exhaust gas, and the exhaust gas is treated pollution-free after the test is completed to avoid polluting the environment. Therefore, since the exhaust gas will not flow back into the compressor test system, it will not contaminate the test gas during the test, thereby ensuring the accuracy and authenticity of the test.

[0034] Continue reading Figure 1 In some embodiments, an air inlet pipe 10 and an air outlet pipe 11 are also included.

[0035] The test assembly 300 includes at least a temperature monitoring unit 4 and a pressure monitoring unit 5 .

[0036] A first end of the air inlet pipe 10 is connected to an air inlet 24 of the compressor 2 , a second end of the air inlet pipe 10 is connected to a first end of an air outlet pipe 11 , and a second end of the air outlet pipe 11 is connected to an air outlet 3 of the compressor 2 .

[0037] The second end of the air supply valve 18 is connected to the air intake pipe 10 .

[0038] The temperature monitoring unit 4 and the pressure monitoring unit 5 are arranged at the connection between the air inlet pipe 10 and the air inlet 24 of the compressor 2 , and at the connection between the air outlet pipe 11 and the air outlet 3 of the compressor 2 .

[0039] The air extraction component 100 is connected to the air outlet pipe 11 .

[0040] like Figure 1 As shown, during the operation of the compressor 2, the gas inside it is in a circulating state, so in order to simulate the actual working scene of the compressor 2, the embodiment of the present application also provides an air intake pipe 10 and an air outlet pipe 11. The air intake pipe 10 is actually connected to the air outlet pipe 11, and the air intake pipe 10 is connected to the air intake port 24 of the compressor 2, and the air outlet pipe 11 is connected to the air outlet 3 of the compressor 2, so in fact, the air intake port 24 of the compressor 2 can be connected to the air outlet 3 based on the external air intake pipe 10 and the air outlet pipe 11.

[0041] The temperature monitoring unit 4 and the pressure monitoring unit 5 can be arranged at the connection between the air intake pipe 10 and the air intake port 24 of the compressor 2, and at the connection between the air outlet pipe 11 and the air outlet port 3 of the compressor 2. More specifically, they can be arranged in the air intake pipe 10 and close to the air intake port 24 of the compressor 2, and in the air outlet pipe 11 and at the air outlet port 3 of the compressor 2. Thus, the temperature and pressure of the air outlet port 3 and the air intake port 24 of the compressor 2 can be detected.

[0042] The temperature monitoring unit 4 may be a thermal resistor, a thermocouple or other temperature measuring elements, and the pressure monitoring unit 5 may be a pressure sensor, etc., which are not particularly limited here.

[0043] Continue reading Figure 1 In some embodiments, the gas injection assembly 200 includes a gas storage tank 15 , a pressure-suppressing tank 16 , a gas injection valve 17 and a gas replenishing valve 18 .

[0044] The gas storage tank 15 is connected to a first end of the gas injection valve 17 , a second end of the gas injection valve 17 is connected to a first end of the pressure stabilizing tank 16 , a second end of the pressure stabilizing tank 16 is connected to a first end of the gas replenishing valve 18 , and a second end of the gas replenishing valve 18 is connected to the gas outlet pipe 11 .

[0045] The gas storage tank 15 is used to store test gas, the gas injection valve 17 is used to control the connection between the gas storage tank 15 and the pressure-stabilizing tank 16, the pressure-stabilizing tank 16 is used to fill the compressor 2 with test gas at a fixed air pressure, and the gas replenishing valve 18 is used to control the connection between the pressure-stabilizing tank 16 and the air inlet 24 of the compressor 2.

[0046] Specifically, the gas injection assembly 200 in the embodiment of the present application is mainly composed of two parts, namely, a gas storage tank 15 and a pressure-suppressing tank 16. Among them, the gas storage tank 15 and the pressure-suppressing tank 16 are both used to store test gas, but the difference is that the gas storage tank 15 is simply used to store test gas, and can be considered to store test gas for a long time, while the pressure-suppressing tank 16 only stores test gas briefly during the test. Although the gas storage tank 15 can output test gas, the output air pressure is unstable during the continuous output of test gas. Therefore, the embodiment of the present application is additionally provided with a pressure-suppressing tank 16, and the pressure-suppressing tank 16 is used to output pressure-stable test gas to the compressor 2. In this way, it can be avoided that in the process of outputting test gas to the compressor 2, damage to the compressor 2 or inaccurate test results due to excessive or insufficient pressure can be avoided.

[0047] Continue reading Figure 1 In some embodiments, an air intake regulating unit 22 is also included.

[0048] The test assembly 300 further comprises a flow monitoring unit 9 .

[0049] The air intake regulating unit 22 is connected to the air intake pipeline 10 and is used to regulate the gas flow in the air intake pipeline 10 .

[0050] The flow monitoring unit 9 is disposed in the air intake pipe 10 and is disposed on a side of the air intake regulating unit 22 away from the air intake port 24 of the compressor 2 .

[0051] Specifically, the intake regulating unit 22 may be an intake guide vane valve, which may control the size of the opening area by adjusting the angle of the guide vane, thereby adjusting the flow size in the intake duct 10 , and the flow monitoring unit 9 may monitor the flow in the intake duct 10 .

[0052] In some embodiments, a heat exchange unit 12 is further included.

[0053] A first end of the heat exchange unit 12 is connected to a second end of the air inlet pipe 10 , and a second end of the heat exchange unit 12 is connected to a first end of the air outlet pipe 11 .

[0054] The heat exchange unit 12 can be connected to the air inlet pipe 10 and the air outlet pipe 11 of the compressor 2. The compressed gas enters the heat exchange unit 12 and exchanges heat with other structures, then enters the air inlet pipe, and finally flows back to the compressor 2. The heat exchange unit 12 can be a silicon carbide heat exchanger or a stainless steel silicon carbide heat exchanger, etc., which is not particularly limited here.

[0055] like Figure 1 As shown, in some embodiments, a coarse pressure adjustment unit 6 and a fine pressure adjustment unit 7 are also included.

[0056] The pressure coarse adjustment unit 6 is connected to the air outlet pipe 11 .

[0057] The pressure fine adjustment unit 7 is connected to the air outlet pipe 11 , and is connected in parallel with the pressure coarse adjustment unit 6 .

[0058] Specifically, both the coarse pressure adjustment unit 6 and the fine pressure adjustment unit 7 can be pressure regulating valves. The coarse pressure adjustment unit 6 is used for rapid pressure adjustment, and the fine pressure adjustment unit 7 is used for precise pressure adjustment.

[0059] Continue reading Figure 1 The compressor test system in the embodiment of the present application may further include a first water regulating valve 13, which may be disposed near the water inlet of the heat exchange unit 12. By disposing the first water regulating valve 13, the flow of the heat exchange medium entering the heat exchange unit 12 may be regulated, thereby achieving temperature regulation. In addition, by regulating the temperature, not only the temperature of the gas in the compressor test system may be controlled, but also the pressure of the gas in the compressor test system may be fine-tuned.

[0060] Continue reading Figure 1The heat exchange unit 12 in the embodiment of the present application is further provided with another water inlet circuit connected to the interstage cooler 23 of the compressor 2, and is further provided with a second water regulating valve 14 provided in the water inlet circuit for regulating the flow of the heat exchange medium entering the interstage cooler 23. The second water regulating valve is connected to the interstage cooler 23 through the cooler water pipeline 19.

[0061] Continue reading Figure 1 The compressor testing system in the embodiment of the present application may further include a pipeline expansion joint 8 , which is disposed on the outlet pipeline 11 and connected between the pressure coarse adjustment unit 6 and the heat exchange unit 12 .

[0062] Continue reading Figure 1 The compressor testing system in the embodiment of the present application may further include a control cabinet 1, which is electrically connected to electrical components such as the test component 300, the compressor 2, the air extraction component 100, and the air injection component 200, and is used to control the operation of each electrical component.

[0063] In some embodiments, the embodiment of the present application may also connect an air injection unit (not shown) to the first end of the pressure stabilizing tank 16, and the air injection unit may be used to inject air (or other safety gas) into the pressure stabilizing tank 16 to flush the compressor 2 and the compressor test system with test gas, so as to prevent the test gas from remaining in the compressor 2 and the compressor test system. Alternatively, the test gas may be mixed with air and then introduced into the compressor 2 and the compressor test system.

[0064] Exemplarily, the air injection unit may also include only one interface, one end of which is connected to the pressure-suppressing tank 16, and the other end of which is connected to the external environment. When the pressure-suppressing tank 16 is under negative pressure, the external air pressure is relatively high, and the pressure-suppressing tank 16 can inhale external air. In addition, although the present application provides an air injection unit, in some embodiments, the gas injected into the pressure-suppressing tank by the air injection unit is not limited to air, but may also be other safer gases to flush the compressor 2 and the structure in the compressor test system that stores the test gas, for example, an inert gas may be used. The "air injection unit" here does not affect the type of gas used for the flushing operation.

[0065] Figure 2 A flow chart of a compressor testing method provided in an embodiment of the present application is provided. The method is implemented based on a compressor testing system as in any one of the above compressor testing system embodiments. The method includes: S101, controlling the air extraction component to extract the gas in the compressor to put the compressor in a target state.

[0066] S102, controlling the gas injection assembly to inject test gas into the compressor.

[0067] S103, controlling the test component to test the working parameters of the compressor.

[0068] Specifically, in order to test the compressor under real working conditions in the embodiment of the present application, the original gas in the compressor and the compressor test assembly can be completely emptied during the test to avoid interference of the original gas with the test. Then, the test gas is injected into the compressor through the gas injection assembly. In this way, all the gas in the compressor and the compressor test system is test gas. Then, the operation of the compressor is controlled, and the working parameters of the compressor are tested until the test is completed. It should be noted that in some scenarios, the gas injection operation can be performed without completely emptying the original gas in the compressor and the compressor test assembly, and the specific setting can be based on actual needs.

[0069] In some embodiments, controlling the air extraction component to extract gas from the compressor so that the compressor is in a vacuum state includes: The gas injection valve is controlled to be closed, and the gas supply valve, the air intake regulating unit, the pressure coarse regulating unit, and the pressure fine regulating unit 7 are controlled to be opened.

[0070] The air extraction component is controlled to extract the gas in the compressor, so that the compressor is in a target state, and the air inlet pipe, the air outlet pipe, and the pressure-surge tank are in a target state.

[0071] Control the gas injection assembly to inject test gas into the compressor, including: Control the air supply valve to close.

[0072] The gas injection valve is controlled to open, and the test gas is charged into the pressure regulating tank until the gas pressure in the pressure regulating tank is greater than or equal to the gas pressure threshold.

[0073] The air injection valve is controlled to be closed, and the air supply valve is controlled to be opened, and the test gas is filled into the compressor, the air inlet pipe and the air outlet pipe until the pressure at the air inlet of the compressor reaches the pressure threshold.

[0074] Continue reading Figure 1 Specifically, the vacuum pump 21 can first be used to evacuate the entire compressor 2 and the compressor test system to a target state that meets the pressure requirements, such as a vacuum state. At this time, all valves except the gas injection valve 17 are open. In this way, the compressor 2, the air inlet pipe 10, the air outlet pipe 11 and the pressure-stabilizing tank 16 are all in the target state, such as a vacuum state.

[0075] Then, the vacuum pump 21 and the air supply valve 18 are closed, and the air injection valve 17 is opened to fill the test gas in the gas storage tank 15 into the pressure regulating tank 16 until the gas volume required for the test is reached, that is, the air pressure is greater than or equal to the air pressure threshold, and then the air injection valve 17 is closed.

[0076] Start the compressor 2 and slowly open the air supply valve 18 to allow the test medium to fill the entire compressor 2 and the compressor test system. When the pressure at the air inlet 24 of the compressor 2 reaches the pressure threshold (a slight positive pressure is sufficient, generally 5-10 kPa), close the air supply valve 18.

[0077] Adjust the air intake adjustment unit 22, the coarse pressure adjustment unit 6, the fine pressure adjustment unit 7, the first water regulating valve 13, and the second water regulating valve 14 to control the flow, pressure, and temperature parameters of the inlet and outlet of the compressor 2, and transmit these operating parameters to the control cabinet 1 through the corresponding sensors (flow monitoring unit 9, pressure monitoring unit 5, temperature monitoring unit 4).

[0078] If the test gas leaks during the test and causes the pressure to drop, the gas replenishment valve 18 is opened to replenish the gas. Finally, the inlet and outlet temperature, pressure, and flow parameters of the compressor 2 are obtained, that is, the performance test result of the compressor 2 is obtained.

[0079] In some embodiments, the method further comprises: After confirming that the test is completed, the exhaust assembly is controlled to exhaust the test gas in the compressor.

[0080] Continue reading Figure 1 After the test is completed, the gas injection valve 17 is closed, the gas supply valve 18 is opened, and the air pump 21 is started to extract the medium in the system to prevent leakage.

[0081] In some embodiments, the method further comprises: The compressor, the air inlet pipe and the air outlet pipe are flushed, and the air injection unit is controlled to inject air into the pressure regulating tank.

[0082] The air supply valve is controlled to open to fill air into the compressor, the air inlet pipe and the air outlet pipe.

[0083] When it is necessary to flush the compressor 2 and the compressor test system (i.e., the air inlet pipe 10, the air outlet pipe 11, etc.), flushing gas, such as air, can be passed into the pressure-stabilizing tank 16. Due to the effect of the negative pressure of the system, the compressor 2 and the compressor test system are filled, and the vacuum pump 21 is started again after filling; this step can be repeated multiple times to flush the compressor 2 and the compressor test system.

[0084] In some embodiments, a preparation step is further included before testing the compressor 2 to test the pipeline sealing performance. A gas medium (such as air) can be input into the compressor 2 and the compressor test system to make the compressor 2 and the compressor test system have a positive pressure (greater than the external gas pressure), and the pressure change is observed after a certain period of time. When it is determined that the pressure is stable, it can be determined that there is no leakage problem, and the test can be started.
