Description

Technical Field

[0001] This invention relates to the field of fluid machinery technology, specifically to a performance testing method and system for hydrogen compressors. Background Technology

[0002] A hydrogen compressor is a device specifically designed to compress low-pressure hydrogen to a high-pressure state. It is widely used in hydrogen refueling stations, petrochemicals, chlor-alkali industries, and hydrogen energy storage. Its core function is to increase the volumetric energy density of hydrogen, facilitating storage, transportation, and refueling. The performance testing method for hydrogen compressors involves a systematic examination of key indicators such as exhaust pressure, volumetric flow rate, specific power, sealing performance, and energy consumption to ensure the safe and efficient operation of the equipment.

[0003] Existing methods for performance testing of hydrogen compressors are costly due to the high cost of using pure hydrogen for the entire testing process and the stringent explosion-proof controls. They typically employ nitrogen or helium as a single alternative medium for offline testing, or use a small flow of pure hydrogen for single-point testing to assess the compressor's performance. While these improved methods can test hydrogen compressor performance at a lower cost, they suffer from inconsistencies in the boundary conditions and parameter benchmarks between helium and hydrogen. This inconsistency leads to distorted comparisons based on alternative media, making it difficult to accurately determine the accuracy of test parameters after hydrogen is introduced. This results in operational safety and performance inaccuracies. Other methods for performance testing of hydrogen compressors... Improvements typically involve diversifying testing methods. For example, patent application CN121676352A discloses a hydrogen compressor testing device and method. This solution can meet the needs of various hydrogen compressor type tests, factory tests, and scientific research tests, providing support for unit design, simulation, and performance evaluation. However, it still cannot solve the problem of inaccurate comparison results when comparing performance based on alternative media due to inconsistent boundary conditions and parameter benchmarks between helium and hydrogen in compressor performance calibration and safety verification. This makes it impossible to accurately identify whether the test parameters after hydrogen is introduced are accurate, resulting in operational safety and performance inaccuracies. Therefore, it is necessary to improve the existing performance testing methods for hydrogen compressors. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems in the prior art. By providing a performance testing method and system for a hydrogen compressor, it is used to solve the problems in the existing performance testing methods for hydrogen compressors. In terms of compressor performance calibration and safety verification, due to the inconsistent boundary conditions of helium and hydrogen working conditions and the non-uniform parameter benchmarks, the comparison results are distorted when comparing performance based on alternative media, and it is impossible to accurately distinguish whether the test parameters after introducing hydrogen are accurate, resulting in inaccurate safety and performance during operation.

[0005] To achieve the above object, in the first aspect, the present application provides a performance testing method for a hydrogen compressor, including the following steps: Circulatingly cleaning a hydrogen compressor operating normally with an inert gas, and locking the operating conditions and environmental conditions of the hydrogen compressor after cleaning; introducing helium into the hydrogen compressor, and obtaining gas reference operations and helium reference parameters using the reference comparison analysis method; Circulatingly cleaning the hydrogen compressor after performing the reference comparison analysis method with an inert gas; introducing hydrogen into the hydrogen compressor after cleaning, and performing the standard hydrogen test method based on the gas reference operations; obtaining hydrogen reference parameters based on the standard hydrogen test method; Obtaining a performance determination region based on the helium reference parameters and the hydrogen reference parameters; when performing a performance test on the hydrogen compressor, obtaining the performance test result of the hydrogen compressor based on the gas reference operations and the performance determination region.

[0006] Further, circulatingly cleaning a hydrogen compressor operating normally with an inert gas, and locking the operating conditions and environmental conditions of the hydrogen compressor after cleaning includes: Operating the hydrogen compressor normally based on the process requirements of the hydrogen compressor, and introducing an inert gas into the intake port of the hydrogen compressor to perform circulating cleaning on the whole machine, pipeline cavity and valve group flow channel of the compressor for a time T; After introducing the inert gas, obtaining the water vapor content and combustible gas content in the whole machine, pipeline cavity and valve group flow channel of the compressor in real time based on a water vapor sensor and a combustible gas sensor, and respectively recording them as the cavity water vapor content and the cavity combustible content.

[0007] Further, circulatingly cleaning a hydrogen compressor operating normally with an inert gas, and locking the operating conditions and environmental conditions of the hydrogen compressor after cleaning further includes: When both the cavity water vapor content and the cavity combustible content meet the process requirements when the hydrogen compressor completes equipment preheating, obtaining the basic operating conditions and environmental boundary conditions of the hydrogen compressor based on the sensors supporting the hydrogen compressor and the multi-modal environmental sensors, and respectively recording them as the standard conditions and the standard environment; The basic operating conditions of the hydrogen compressor are locked as standard operating conditions based on electronic control and industrial process instruments; the environmental boundary conditions of the hydrogen compressor are locked as standard environment based on environmental control equipment in the environment in which the hydrogen compressor is located.

[0008] Furthermore, benchmark comparison analysis includes: Helium is introduced into the hydrogen compressor, and the hydrogen compressor is controlled to maintain closed-loop operation. The time when helium is introduced into the hydrogen compressor is recorded as T1. Based on the process standards of the hydrogen compressor during operation, the intervals corresponding to the pressure parameters, temperature parameters, flow parameters and vibration parameters of the hydrogen compressor during steady-state operation are obtained and recorded as the steady-state stable interval. After helium is introduced into the hydrogen compressor, the time when the pressure, temperature, flow rate, and vibration parameters inside the hydrogen compressor are all in their corresponding steady-state ranges for the first time is recorded as T2. The interval [T1, T2] is denoted as the stable adjustment interval, and the interval [T2, T3] is denoted as the stable acquisition interval, where T3 is the time point in the time axis that is greater than T2.

[0009] Furthermore, the benchmark comparison analysis method also includes: For the stable control range: the operation of regulating the power speed control device, pressure regulating valve, cooling control component and pipeline on / off valve in the hydrogen compressor within the stable control range is recorded as the gas reference operation. Obtain the time-dependent curves of all pressure parameters, temperature parameters, flow rate parameters, and vibration parameters within the stable adjustment range, and record them as stable adjustment curves; For the stable acquisition range: obtain the time-dependent curves of all pressure parameters, temperature parameters, flow parameters, and vibration parameters within the stable adjustment range, and record them as stable acquisition curves; The stable adjustment curves and stable acquisition curves corresponding to all pressure parameters, temperature parameters, flow parameters, and vibration parameters are recorded as helium reference parameters.

[0010] Furthermore, the process of cyclically cleaning the hydrogen compressor after performing the benchmark comparative analysis using inert gas includes: After time T2, the hydrogen compressor with the obtained gas reference operation and helium reference parameters is circulated and cleaned using inert gas; the maximum helium concentration in the entire compressor, pipeline cavity and valve group flow channel of the hydrogen compressor is obtained in real time and recorded as the cleaning helium concentration. When the concentration of helium gas used for cleaning is less than or equal to the standard residual concentration, the basic operating condition of the hydrogen compressor is locked to the standard operating condition based on electronic control and industrial process instruments. The environmental boundary conditions of the hydrogen compressor are locked to the standard environment based on the environmental control equipment in the environment where the hydrogen compressor is located, and hydrogen gas is introduced into the hydrogen compressor.

[0011] Furthermore, the standard hydrogen testing method includes: The time when hydrogen is introduced into the hydrogen compressor is recorded as T4. After the hydrogen is introduced into the hydrogen compressor, the operation corresponding to the control of the power speed regulating device, pressure regulating valve, cooling control component and pipeline on / off valve in the hydrogen compressor is the same as the gas reference operation, and the pressure parameters, temperature parameters, flow parameters and vibration parameters of the hydrogen compressor are collected in real time. When the time is T5, the curves of all pressure parameters, temperature parameters, flow parameters and vibration parameters in the time interval [T4, T5] and time are recorded as hydrogen regulation curves. The time interval [T4, T5] has the same interval length as the stable regulation interval. When the time is T6, the curves of all pressure parameters, temperature parameters, flow parameters and vibration parameters in the time interval [T5, T6] and their relationship with time are recorded as hydrogen stability curves. The time interval [T5, T6] has the same length as the stable acquisition interval. The hydrogen conditioning curve and the hydrogen stability curve are recorded as the hydrogen reference parameters.

[0012] Furthermore, the performance determination region obtained based on helium reference parameters and hydrogen reference parameters includes: For any parameter α among pressure, temperature, flow, and vibration parameters: denote the unit corresponding to parameter α as β, and construct a regulation analysis coordinate system and a stability analysis coordinate system respectively. The units of the X-axis and Y-axis of the regulation analysis coordinate system and the stability analysis coordinate system are time and β respectively. Place the stable adjustment curve corresponding to parameter α and the hydrogen adjustment curve in the adjustment analysis coordinate system, and denote the region between the two curves in the adjustment analysis coordinate system as the adjustment difference region. Place the stable acquisition curve corresponding to parameter α and the hydrogen stability curve in the stability analysis coordinate system, and denote the region between the two curves in the stability analysis coordinate system as the stability difference region. Obtain the adjustment difference region and stability difference region corresponding to all pressure parameters, temperature parameters, flow parameters and vibration parameters, and record them as the performance judgment region.

[0013] Furthermore, when performing performance tests on a hydrogen compressor, the performance test results obtained based on gas reference operation and performance judgment range include: When performing performance tests on a hydrogen compressor, after hydrogen is introduced into the compressor, the differences between the controlled operation of the power speed control device, pressure regulating valve, cooling control component, and pipeline on / off valve and the gas reference operation are compared in real time. Before the hydrogen compressor reaches steady-state operation, if the controlled operation of any one of the following devices γ is different from the gas reference operation, the device γ is recorded as a performance defective device. After hydrogen is introduced into the hydrogen compressor, for any parameter α among pressure parameters, temperature parameters, flow rate parameters and vibration parameters, the hydrogen adjustment curve and hydrogen stability curve corresponding to parameter α are obtained based on the standard hydrogen testing method, and are respectively recorded as the real-time adjustment curve and the real-time stability curve. Place the real-time adjustment curve in the adjustment analysis coordinate system corresponding to parameter α, and denote the area between the real-time adjustment curve and the stable adjustment curve as the real-time adjustment region. When any part δ in the real-time adjustment region is above the adjustment difference region, the test result of parameter α in the performance test is recorded as the value being too large before the hydrogen compressor stabilizes. When any part δ in the real-time adjustment region is below the adjustment difference region, the test result of parameter α in the performance test is recorded as the value being too small before the hydrogen compressor stabilizes. Place the real-time stable curve in the stable analysis coordinate system corresponding to parameter α, and denote the region between the real-time stable curve and the stable acquisition curve as the real-time stable region. When any part of δ in the real-time stable region is above the stable difference region, the test result of parameter α in the performance test is recorded as a value that is too large after the hydrogen compressor has been running stably. When any part of δ in the real-time stable region is below the stable difference region, the test result of parameter α in the performance test is recorded as a value that is too small after the hydrogen compressor has been running stably.

[0014] Secondly, this application also provides a performance testing system for a hydrogen compressor, including a helium benchmark analysis module, a hydrogen parameter acquisition module, and a comparison test analysis module. The helium reference analysis module is used to circulate and clean the hydrogen compressor under normal operation using inert gas, and lock the operating conditions and environmental conditions of the hydrogen compressor after cleaning; helium is introduced into the hydrogen compressor, and the gas reference operation and helium reference parameters are obtained using the reference comparison analysis method. The hydrogen parameter acquisition module is used to perform a circulating cleaning of the hydrogen compressor after the benchmark comparative analysis method is performed using an inert gas; after cleaning, hydrogen is introduced into the hydrogen compressor, and the standard hydrogen test method is performed based on the gas benchmark operation; and hydrogen benchmark parameters are acquired based on the standard hydrogen test method. The comparative test analysis module is used to obtain the performance judgment region based on helium and hydrogen reference parameters; when the performance of the hydrogen compressor is tested, the performance test results of the hydrogen compressor are obtained based on the gas reference operation and the performance judgment region.

[0015] The beneficial effects of this invention are as follows: First, an inert gas is used to circulate and clean the hydrogen compressor under normal operation, and the operating conditions and environmental conditions of the hydrogen compressor are locked after cleaning. Helium is then introduced into the hydrogen compressor, and a benchmark comparison analysis method is used to obtain the gas benchmark operation and helium benchmark parameters. The advantage of this is that by using an inert gas to circulate and clean the entire machine cavity and flow channel and locking the operating conditions and environmental conditions, test interference caused by impurities, water vapor, and environmental fluctuations can be avoided, thereby ensuring that the benchmark operating conditions are unique and controllable during subsequent tests. Introducing helium and using a benchmark comparison analysis method to obtain the gas benchmark operation and helium benchmark parameters can eliminate system deviations caused by medium switching and equipment adjustment differences, thereby ensuring more accurate subsequent data analysis. This application also uses an inert gas to perform a cyclic cleaning of the hydrogen compressor after the benchmark comparative analysis method is executed; after cleaning, hydrogen is introduced into the hydrogen compressor, and a standard hydrogen test method is performed based on gas benchmark operation; hydrogen benchmark parameters are obtained based on the standard hydrogen test method; finally, a performance judgment region is obtained based on helium benchmark parameters and hydrogen benchmark parameters; when the performance of the hydrogen compressor is tested, the performance test results of the hydrogen compressor are obtained based on gas benchmark operation and the performance judgment region. The advantage of this is that performing the standard hydrogen test method based on gas benchmark operation after cleaning can eliminate variable errors caused by human operation and changes in operating conditions, thereby making the helium benchmark parameters and hydrogen benchmark parameters highly comparable. In the subsequent acquisition of the performance judgment region, the problem of inconsistency in the boundary conditions of helium and hydrogen operating conditions and the lack of unified parameter benchmarks can be avoided, thus ensuring that when the performance of the hydrogen compressor is tested, the accuracy of the test parameters after the introduction of hydrogen can be effectively identified based on gas benchmark operation and helium benchmark parameters, thereby improving the safety of hydrogen compressor test operation and the accuracy of performance judgment.

In the data analysis of this embodiment, the value of T is set to 1 hour, and the inert gas used is nitrogen; After introducing the inert gas, based on the water vapor sensor and the combustible gas sensor, the water vapor content and combustible gas content in the whole machine, pipeline cavity, and valve group flow channel of the compressor are obtained in real time, and are respectively recorded as the cavity water vapor content and the cavity combustible content; When both the cavity water vapor content and the cavity combustible content meet the process requirements when the hydrogen compressor completes equipment preheating, the basic operating conditions and environmental boundary conditions of the hydrogen compressor are obtained based on the sensors supporting the hydrogen compressor and the multimodal environmental sensors, and are respectively recorded as the standard conditions and the standard environment; In the data analysis of this embodiment, the basic operating conditions include the operating process conditions and the equipment body conditions. Among them, the operating process conditions may include conditions such as rotational speed, inlet and outlet pressures, medium flow rate, cooling conditions, and operating status, and the equipment body conditions may include the body temperature, bearing temperature, oil pressure, and vibration base value, which can be collected in real time and maintained stably by the sensors supporting the hydrogen compressor; the multimodal environmental sensors used to obtain the environmental boundary conditions may include temperature and humidity integrated sensors, atmospheric pressure sensors, environmental wind speed and airflow sensors, and explosion-proof composite sensors; after obtaining the environmental boundary conditions, the environmental control equipment in the space where the hydrogen compressor is located can be used to maintain the environmental temperature, humidity, and atmospheric pressure under standard environmental conditions, avoiding the influence of environmental fluctuations on the test results during subsequent tests and causing distortion of parameter acquisition. Among them, the environmental control equipment may include a workshop constant temperature area, enclosures for isolation, and air conditioners for constant temperature and pressure stabilization, etc.; Based on the electric control regulation and industrial process instruments, the basic operating conditions of the hydrogen compressor are locked as standard conditions; based on the environmental control equipment in the environment where the hydrogen compressor is located, the environmental boundary conditions of the hydrogen compressor are locked as the standard environment.

[0019] The reference comparison analysis method includes: introducing helium into the hydrogen compressor, controlling the hydrogen compressor to maintain closed-loop circulation operation, and recording the time when helium is introduced into the hydrogen compressor as T1; based on the process standards during the operation of the hydrogen compressor, obtaining the intervals corresponding to the pressure-type parameters, temperature-type parameters, flow-type parameters, and vibration-type parameters when the hydrogen compressor is in steady-state operation, and recording them as the steady-state stable intervals; In the specific implementation process, the pressure-type parameters, temperature-type parameters, flow-type parameters, and vibration-type parameters can be specifically set according to the parameters that can be collected during the operation of the actually tested hydrogen compressor; in the data analysis of this embodiment, the pressure-type parameters include: the real-time inlet pressure of each stage, the real-time outlet pressure of each stage, the pressure of the inter-stage buffer tank, and the real-time value of the pipeline pressure drop; the temperature-type parameters include: the exhaust temperature of each stage, the temperature of the compressor body shell, the bearing operating temperature, the inlet and outlet medium temperatures, and the inlet and outlet temperatures of the cooling water; the flow-type parameters include: the real-time mass flow rate of the medium and the real-time change amount of the volumetric efficiency; the vibration-type parameters include: the time-domain amplitude of the body vibration, the vibration fluctuation curve, the valve group opening and closing response time sequence, the real-time concentration value of the micro-leakage at the sealing part, and the time-sequence fluctuation of the overall operating noise; After introducing helium into the hydrogen compressor, the time when the pressure-type parameters, temperature-type parameters, flow-type parameters, and vibration-type parameters in the hydrogen compressor first all fall within the corresponding steady-state stable intervals is recorded as T2; The interval [T1, T2] is recorded as the stable adjustment interval, and the interval [T2, T3] is recorded as the stable acquisition interval, where T3 is a time point greater than T2 on the time axis; In the data analysis of this embodiment, for example, during a data analysis, if the time when helium is introduced into the hydrogen compressor is 12:00 in the benchmark comparison analysis method, and the time when the pressure parameters, temperature parameters, flow parameters, and vibration parameters in the hydrogen compressor are all in the corresponding steady-state range for the first time is 12:30, then through analysis, it can be seen that [12:00, 12:30] can be recorded as the stable adjustment range; the value of T3 can be determined according to the time when the hydrogen compressor can maintain steady-state operation during actual testing. In this embodiment, the value of T3 is set to 13:00, that is, after the hydrogen compressor reaches steady state, it continues to run for 30 minutes, and [12:30, 13:00] is recorded as the stable acquisition range.

[0020] The benchmark comparison analysis method also includes: For the stable control range: the operation of regulating the power speed control device, pressure regulating valve, cooling control component and pipeline on / off valve in the hydrogen compressor within the stable control range is recorded as the gas benchmark operation; In the data analysis of this embodiment, the power speed regulating device may include a frequency converter; the pressure regulating valve may include an intake pressure regulating valve and an exhaust back pressure valve; the cooling control component may include a cooling water regulating valve and a cooling circulation pump; the pipeline on / off valve may include a medium on / off valve and a bypass control valve; in specific implementation, the gas reference operation can be adjusted to conform to the actual working conditions according to the equipment that can perform operation detection in the hydrogen compressor during operation, thereby ensuring that the system deviation caused by the equipment adjustment difference is eliminated during subsequent testing and improving the accuracy of data acquisition; Obtain the time-dependent curves of all pressure parameters, temperature parameters, flow rate parameters, and vibration parameters within the stable adjustment range, and record them as stable adjustment curves; For the stable acquisition range: obtain the time-dependent curves of all pressure parameters, temperature parameters, flow parameters, and vibration parameters within the stable adjustment range, and record them as stable acquisition curves; The stable adjustment curves and stable acquisition curves corresponding to all pressure parameters, temperature parameters, flow parameters, and vibration parameters are recorded as helium reference parameters; In the specific implementation process, by introducing helium into the hydrogen compressor to obtain the helium reference parameters corresponding to pressure, temperature, flow and vibration parameters, a benchmark can be established based on the stable and low-risk characteristics of helium, avoiding the safety hazards and high cost of repeatedly testing with hydrogen directly, thereby achieving low-cost, high-safety and high-precision compressor performance evaluation.

[0021] The hydrogen parameter acquisition module is used to perform a circulating cleaning of the hydrogen compressor after the benchmark comparative analysis method is performed using an inert gas; after cleaning, hydrogen is introduced into the hydrogen compressor, and the standard hydrogen test method is performed based on the gas benchmark operation; and hydrogen benchmark parameters are acquired based on the standard hydrogen test method. The hydrogen parameter acquisition module includes a hydrogen parameter acquisition unit, which is configured with a hydrogen parameter acquisition strategy. The hydrogen parameter acquisition strategy includes: After time T2, the hydrogen compressor with the obtained gas reference operation and helium reference parameters is circulated and cleaned using inert gas; the maximum helium concentration in the entire compressor, pipeline cavity and valve group flow channel of the hydrogen compressor is obtained in real time and recorded as the cleaning helium concentration. When the concentration of helium gas used for cleaning is less than or equal to the standard residual concentration, the basic operating condition of the hydrogen compressor is locked to the standard operating condition based on electronic control and industrial process instruments. The environmental boundary conditions of the hydrogen compressor are locked to the standard environment based on the environmental control equipment in the environment where the hydrogen compressor is located, and hydrogen gas is introduced into the hydrogen compressor.

[0022] The standard hydrogen testing method includes: recording the time when hydrogen is introduced into the hydrogen compressor as T4; after the hydrogen is introduced into the hydrogen compressor, keeping the operation of the power speed regulating device, pressure regulating valve, cooling control component and pipeline on / off valve in the hydrogen compressor the same as the gas reference operation, and collecting the pressure parameters, temperature parameters, flow parameters and vibration parameters of the hydrogen compressor in real time. When the time is T5, the curves of all pressure parameters, temperature parameters, flow parameters and vibration parameters in the time interval [T4, T5] and time are recorded as hydrogen regulation curves. The time interval [T4, T5] has the same interval length as the stable regulation interval. When the time is T6, the curves of all pressure parameters, temperature parameters, flow parameters and vibration parameters in the time interval [T5, T6] and their relationship with time are recorded as hydrogen stability curves. The time interval [T5, T6] has the same length as the stable acquisition interval. In the data analysis of this embodiment, since the stable adjustment interval and stable acquisition interval in the above analysis are [12:00, 12:30] and [12:30, 13:00] respectively, when the value of T4 is 14:00, it can be obtained through analysis that [T4, T5] should be [14:00, 14:30], that is, T5 is 14:30; and so on, [T5, T6] should be [14:30, 15:00], and T6 is 15:00; therefore, the curves corresponding to various parameters in the time intervals of [14:00, 14:30] and [14:30, 15:00] should be recorded as the hydrogen adjustment curve and the hydrogen stability curve respectively. The hydrogen conditioning curve and the hydrogen stability curve are recorded as the hydrogen reference parameters.

[0023] The comparison test analysis module is used to obtain the performance judgment area based on helium reference parameters and hydrogen reference parameters; when the performance of the hydrogen compressor is tested, the performance test results of the hydrogen compressor are obtained based on the gas reference operation and the performance judgment area. The comparison test analysis module includes a comparison test analysis unit, which is configured with a comparison test analysis strategy. The comparison test analysis strategy includes: For any parameter α among pressure, temperature, flow, and vibration parameters: denote the unit corresponding to parameter α as β, and construct a regulation analysis coordinate system and a stability analysis coordinate system respectively. The units of the X-axis and Y-axis of the regulation analysis coordinate system and the stability analysis coordinate system are time and β respectively. Place the stable adjustment curve corresponding to parameter α and the hydrogen adjustment curve in the adjustment analysis coordinate system, and denote the region between the two curves in the adjustment analysis coordinate system as the adjustment difference region. In specific implementation, for example, during a data analysis, one parameter being analyzed is the real-time intake pressure, and the corresponding stable adjustment curves for the real-time intake pressure and the hydrogen adjustment curve are as follows: Figure 3 As shown in the curves WT and QT, analysis reveals that... Figure 3 Regions TC1 and TC2 in the diagram represent regions of moderated difference. Place the stable acquisition curve corresponding to parameter α and the hydrogen stability curve in the stability analysis coordinate system, and denote the region between the two curves in the stability analysis coordinate system as the stability difference region. Obtain the adjustment difference region and stability difference region corresponding to all pressure parameters, temperature parameters, flow parameters and vibration parameters, and record them as the performance judgment region.

[0024] The comparative testing and analysis strategy also includes: when performing performance testing on a hydrogen compressor, after hydrogen is introduced into the compressor, the differences between the controlled operation of the power speed control device, pressure regulating valve, cooling control component, and pipeline on / off valve and the gas reference operation are compared in real time; before the hydrogen compressor is in steady-state operation, if the controlled operation of any one of the power speed control device, pressure regulating valve, cooling control component, and pipeline on / off valve is different from the gas reference operation, the device γ is recorded as a performance defective device; After hydrogen is introduced into the hydrogen compressor, for any parameter α among pressure parameters, temperature parameters, flow rate parameters and vibration parameters, the hydrogen adjustment curve and hydrogen stability curve corresponding to parameter α are obtained based on the standard hydrogen testing method, and are respectively recorded as the real-time adjustment curve and the real-time stability curve. Place the real-time adjustment curve in the adjustment analysis coordinate system corresponding to parameter α, and denote the area between the real-time adjustment curve and the stable adjustment curve as the real-time adjustment region. When any part δ in the real-time adjustment region is above the adjustment difference region, the test result of parameter α in the performance test is recorded as the value being too large before the hydrogen compressor stabilizes. When any part δ in the real-time adjustment region is below the adjustment difference region, the test result of parameter α in the performance test is recorded as the value being too small before the hydrogen compressor stabilizes. In the data analysis of this embodiment, for example, during a single data analysis, one parameter being analyzed is the real-time intake pressure, and the real-time adjustment curve of the acquired real-time intake pressure is as follows: Figure 4 As shown by curve ST in the figure, analysis reveals that the real-time adjustment range is... Figure 4 Regions SC1 and SC2 are shown in the figure; by combining Figure 3 and Figure 4 It can be seen that in the real-time adjustment range of the intake pressure, the highest point is higher than the highest point of the adjustment difference range, and the lowest point is lower than the lowest point of the adjustment difference range. Therefore, it is indicated that the real-time adjustment range of the intake pressure contains both parts above and below the adjustment difference range. According to the judgment criteria of this embodiment, the test result of the intake pressure should be recorded as the value before the hydrogen compressor is stably running, which is both too high and too low. In summary, the performance test result of the intake pressure in the hydrogen compressor is: the value before the hydrogen compressor is stably running is unstable and deviates from the normal range. Place the real-time stable curve in the stable analysis coordinate system corresponding to parameter α, and denote the region between the real-time stable curve and the stable acquisition curve as the real-time stable region. When any part of δ in the real-time stable region is above the stable difference region, the test result of parameter α in the performance test is recorded as a value that is too large after the hydrogen compressor has been running stably. When any part of δ in the real-time stable region is below the stable difference region, the test result of parameter α in the performance test is recorded as a value that is too small after the hydrogen compressor has been running stably.

Step S102: After introducing an inert gas, based on the water vapor sensor and the combustible gas sensor, the water vapor content and the combustible gas content in the whole machine of the compressor, the pipeline cavity, and the valve group flow channel are obtained in real time, and are respectively recorded as the cavity water vapor content and the cavity combustible content.

[0026] Step S1 further includes: Step S103: When both the cavity water vapor content and the cavity combustible content meet the process requirements for the hydrogen compressor to complete equipment preheating, based on the sensors supporting the hydrogen compressor and the multi-modal environment sensor, the basic operating conditions and the environmental boundary conditions of the hydrogen compressor are obtained, and are respectively recorded as the standard conditions and the standard environment; Step S104: Based on the electronic control adjustment and the industrial process instrument, the basic operating conditions of the hydrogen compressor are locked as the standard conditions; based on the environmental control equipment in the environment where the hydrogen compressor is located, the environmental boundary conditions of the hydrogen compressor are locked as the standard environment.
