Causes and Countermeasures of High Vacuum Failure Rate of X-ray Fluorescence Spectrometer
Using statistical methods to analyze the causes of X-ray fluorescence spectrometer failures,the main factor causing the failure rate of the X-ray fluorescence spectrometer is the failure of the vacuum system,and then through layer-by-layer analysis,it is found that high vacuum degree is the main factor of vacuum system failure.Analyze the reasons for the high failure rate of the vacuum degree,from the impact of untimely replacement of the Mylar membrane of the sealed sample tank,the influence of sample preparation pressure,the influence of filter cleaning frequency,the impact of the frequency of seal ring replacement,the influence of the frequency of pump oil replacement,starting from six aspects of the impact of the comprehensive quality of personnel,find out the degree of influence of various factors on the failure rate of high vacuum degree through experiments,according to the degree of influence,the crux of the fault leading to high vacuum degree is obtained.The pressure of sample preparation is low,the long service time of the sealing ring is the main factor affecting the high vacuum of the X-ray fluorescence spectrometer,take increased tablet pressure,the countermeasure of increasing the frequency of replacing the sealing ring reduces the failure rate of high vacuum degree,guaranteed the steady progress of sample analysis,improve the accuracy of the assay,provide timely data support for production,obtained certain economic and social benefits.
