Analysis of air leakage phenomenon and impact of axial flow compressor

Air leakage in axial flow compressors mainly manifests as abnormal loss of compressed gas in the casing, blades and bearing gaps. This phenomenon not only leads to a decrease in compression efficiency, but may also lead to increased equipment vibration, abnormal temperature and risk of failure.According to statistics, a compressor with an air leakage of more than 5% will suffer a performance loss of more than 10%. In severe cases, it may even cause the entire machine to be shut down for maintenance.The causes of air leakage are complex, including component wear, seal failure, and may also be caused by manufacturing tolerances or assembly defects.In response to this phenomenon, the implementation of high-precision air leakage detection technology is a necessary means to ensure the stable operation of axial flow compressors.

Core Technology: Analysis of Air Leakage Detection Methods for Axial Flow Compressors

Currently, axial flow compressor air leakage detection technology mainly includes four core methods: acoustic wave detection, gas tracer detection, thermal imaging diagnosis and pressure difference monitoring.Acoustic detection uses the characteristics of air flow noise generated during compressor operation to capture abnormal signals through acoustic sensors to achieve early warning of air leakage.Gas tracer detection relies on the tracer properties of inert gases such as helium or argon and cooperates with a mass spectrometer to detect leak points, with a sensitivity of up to 10^-6Pa·m³/s.Thermal imaging technology uses infrared imaging equipment to detect local temperature abnormalities and assist in determining the location of leaks.Differential pressure monitoring indirectly identifies the degree of air leakage by comparing pressure changes at different measuring points of the compressor.The combined application of multiple technologies can effectively improve detection accuracy and timeliness.

Practical Steps: Axial Compressor Air Leakage Detection Operation Process

Air leakage detection not only relies on advanced technology, but also requires standardized operating procedures to ensure accurate and reliable data.Common steps include:

1. Equipment preparation:Make sure the compressor is in testing condition, and check that the sensors and testing instruments are calibrated.
2. Initial diagnosis:Use online monitoring systems to collect pressure, temperature and vibration data to locate potential leak areas.
3. Accurate detection:Combine helium tracer and acoustic wave sensing for detailed inspection and mark suspected leak points.
4. Data analysis:Analyze the collected data to determine the degree and location of air leakage and form a detection report.
5. Repair suggestions:Based on the test results, develop maintenance plans and arrange emergency repairs or monitoring and tracking.

This process can ensure that air leakage problems are promptly identified and efficiently treated, maximizing the operational safety of the axial flow compressor.

Industry Trend: The Development Prospects of Intelligent Air Leak Detection and Maintenance

With the development of Industry 4.0 and Internet of Things technology, intelligent air leakage detection systems have become a future trend.The multi-parameter data of the axial flow compressor is collected in real time through the sensor network, and combined with big data analysis and artificial intelligence algorithms, online monitoring and predictive maintenance of air leakage are achieved.According to relevant research, the intelligent early warning system can shorten the response time to air leakage accidents by more than 50% and significantly reduce the risk of equipment shutdown.In addition, remote diagnosis and automatic inspection robots are gradually being used in on-site inspections, bringing convenience and innovation to maintenance work.Maintaining technological leadership and adopting intelligent air leakage detection solutions have become the key to ensuring the competitiveness of high-end axial flow compressor equipment.
