Design Of Pneumatic Performance Testing System For Compressor

The performance test of the compressor is a kind of simulation test which is used to test whether the manufacturing process of the compressor is satisfied with the performance requirements of the user. According to the axial flow, centrifugal compressor and expander compressor "acceptance criteria API617-2002 petroleum, chemical and gas industry, need to through standardized exceeded the means of the compressor aerodynamic performance analysis, test whether meet the contract index. To this end, this paper proposes to establish a comprehensive analysis of the laboratory level of the compressor aerodynamic performance testing system, the completion of the plant process of testing needs.The performance test system of compressor is composed of data acquisition layer, data processing layer, data analysis layer, test management layer and so on. Data acquisition layer by the SIEMENS PLC400 system to achieve the pressure, temperature and speed and other parameters of the collection. Data processing layer to complete the conversion of different measurement and control system in the form of data, and complete pre test preparation phase of the pilot program design calculation and test management data exchange, so you can test scheme for computing the data to upload data according to enable a whole summary, encoded as data analysis layer to be able to use the data structure. Data analysis layer to complete gas dynamic performance data analysis, and according to the test plan calculation parameters, sorting out the compressor section aerodynamic performance analysis and assessment, the whole gas dynamic analysis and evaluation of performance results, different structural states of equilibrium affect tracheal analysis, pumping and filling structure unit cycle calculation, and a summary sorted out the data report, with print, store, modify functions. Test management is mainly to complete the test management and large data collection and analysis of the function. Through test scheme of calculation results, for the test preparation were tracking the whole process of processing, to ensure the normal development of test preparation, on the other hand, according to the data analysis layer upload to the aerodynamic performance analysis results, save to become form that can be aggregated to identify, through continuous accumulation unit of analysis data, to achieve high data summary analysis, and provide effective data support for the design and development, from the process to realize closed-loop development.After the completion of the measurement and control system has been widely used in factory compressor aerodynamic performance test among, and modular control system can separate functions, under certain conditions do not have the state also very good completed the corresponding function.
