The Development Of Piston Compressor Integrated Performance Test System

Piston Compressors are compressors that rely on changes in working chamber volume to increase gas pressure.They are a typical fluid machine and are widely used in petroleum,chemical,energy,power,construction,mining and scientific applications.Piston compressor performance test can grasp and monitor the performance of the compressor performance changes,for its stable operation and maintenance is of great significance.According to the relevant national standards,combined with the specific needs of teaching and research,based on the computer signal acquisition and processing technology,the application of the corresponding sensor,data acquisition board,signal isolation transmitter and other components,combined with the typical characteristics of the displacement compressor,The characteristics of the compressor operating condition signal are characterized,and the window interface design and software programming of Visual Basic advanced computer language are used to design and develop a set of practical performance test system with practical value and versatility.The system through the pressure sensor to collect the waveform voltage signal,close to the switch to collect high and low square wave signal,after conversion into a digital signal input program,followed by the judge to take out a cycle of the pressure signal,the cycle of the pressure signal And the square wave signal to carry out the anti-pulse interference filtering process,effectively remove the interference signal,in order to achieve the compressor process of pressure,displacement of the precise characterization,and based on this accurate drawing of the compressor work diagram,Machine actual flow and other information,and test data can be automatically saved.Finally,based on the performance test platform,the performance test of the piston compressor is carried out.The experimental data are analyzed,and the relationship between the flow rate and the rotational speed of the piston compressor under different working conditions is studied.Analyze the operating characteristics of the compressor.In this paper,the testing platform successful apply in the teaching of undergraduate course,it proves that the piston compressor comprehensive testing system has high precision and good applicability.
