The Actual Surge Test Method and Analysis of Centrifugal Compressor Surge
For the centrifugal compressor surge theory and surge impaction on compressor study,which gives the testing the actual surge line of the compressor is necessary and available.At the different inlet guide angles,the suction flow and discharge pressure were got and obtained the actual surge line.Comparing the testing surge line with expected surge line,which is supplied by the manufacture,the discharge pressures are greater than the expected discharge pressure 16%～19%.Therefore,the actual surge test is necessary for centrifugal compressor.Accurate surge line can improve the compressor safety and save energy.It also gives the safety,high run efficiency and saving energy direction.
