Study On The Application Of Oil Monitoring To Ship Power System & Device

In the last twenty years, with the development of ship maintenance system, oil monitoring technology is applied to ship field gradually, and become an active branch in the application and research field of condition monitoring. In this paper, according to the character of the ship power system and device and the factors that affect it's capability, such as environment, utilizing the experience of the field expert, and combined with the practice of ship manufacturing and maintenance, the application of various oil monitoring technology, namely oil quality testing, spectrometric oil analysis, ferrography analysis, and particle counting etc, is studied respectively, and the fault recognition pattern is constructed. On the basis of this, according to Dempster-Shafter evidence theory, the information infusion mode is constructed and the oil monitoring multi-technology system is integrated. At last, colligating the result of the information infusion system and other information of the device, such as primitive data, maintenance records, running condition etc, the oil monitoring system to ship power system & device is realized.The main function of the oil monitoring system to ship power system & device is: Analyzing the change of the parameters of oil quality, monitoring the inferior change of the oil quality. Analyzing the debris in the oil sample, search after the affiliation between the character (component, concentration, size and distribution, shape and distribution, color etc) and the wear condition and the failure of the part of the device. Study the affection of the contamination in the oil to the performance and condition of the device. Colligating the primitive data, such as the type, running environment, running condition, maintenance activity etc, of the ship power system and device and the experiment data, realizing the condition monitoring and fault diagnosing system, directing the management and using of the oil, providing advice to the maintenance and inspection of the ship power system & device.In this paper, the main job has two aspects: firstly, according to the multi-technology character of the oil monitoring system, the information infusion mode is constructed. Secondly, in the studying of the oil monitoring system, according to the complicated power system and device, multi-information integration analysis method is recommended.
