Joint Condition Monitoring of Large Broaching Machine Using Ferrography and Spectrography;

The effects of high efficiency internal combustion engine break - in oil developed by Petro-chemical Research institute of LPPCC and general engine oil on 492QB16 type gasoline engine were investigatedwith ferrography technology.

The traditional data process and analysis method of quantitative ferrography are discussed in this paper.

Using the lubricant iron spectrum and spectrographic analysis methods to monitor the concentration change of metallic elements in lubricant and to analyze the shape,size,concentration and composition of the wearing particles,the bearing liner wearing status of No 4 gas turbine in Shenzhen Yueliangwan Gas Turbine Power Plant was correctly diagnosed.

With the combined use of iron spectrum analysis,light spectrum analysis and electromicroscope energy spectrum analysis,the operation of 3.

Analyzes the elementary principle and method of ferrography,and describes the flow procedure of ferrography.

Water content,acid number,flash point,burning point and iron content of the oil sample taken from the vehicle in accordance with certain mileage were tested by the method of fast checking in physical & chemical index and ferrography,and the deterioration law of oil was researched.

In this paper, the Ferrography was simply introduced; the application of the Ferrography and image recognition in the fault diagnosis expert system for engines was studied.

The technology of on-line ferrograph is a sort of wear condition realtime monitoring technology which are developed from the analysis ferrograph.

Application and research of ferrography in judging the wear condition of engine;

Application of Ferrography and Comprehensive Diagnosis Technique;

The Application of Weibull Distribution in the Ferrography Based on Debris Group Theory;

Under the condition of sand in oil,the T-11 model ball-on-disk wear tester was used to study the wear performance of composite coating,then the FTP-X2 model ferrograph was performed to study the grindings of composite coating.

Following the tracks of the test on ferrograph-analyzer for typical road-making machinery s lubricating oil,this paper analyzes the laws of change and the factors of effect about the oil sample of the direct - read on the ferrograph - analyzer, and suggests the improvement of ferrograph and the use of the ferrograph analyzing technology.
