“…Roylance et al (2000) introduced 6 main types of wear particles: rubbing, spherical, laminar, cutting, fatigue chunk and severe sliding particles. Raadnui and Kleesuwan (2005) proposed scheduled offline oil sampling for laboratory analysis, based on ferrography and spectroscopy, as the dominating techniques for oil CM. Today there exists a variety of forms of oil based CM methods and techniques to check the volume and nature of foreign particles in oil for equipment health monitoring.…”

This paper presents a review of different approaches for Condition Based Maintenance (CBM) of induction machines and drive trains in offshore applications. The paper contains an overview of common failure modes, monitoring techniques, approaches for diagnostics, and an overview of typical maintenance actions. Although many papers have been written in this area before, this paper puts an emphasis on recent developments and limits the scope to induction machines and drive trains applied in applications located offshore.

In this study, the oil degradation measuring for integrated sensor of drain valve was fabricated. A sensor used in the experiments was integrated with drain valves and installed in oil pan without requiring additional space. As a result of the experiments, the capacitances changed with two inflection points in accordance with an after in mileage. The first inflection point indicated the exhaustion of oil additives, and after the second inflection point, the oil degradation was completed, which increased the viscosity and disabled the functions of oil. Thus, this section was determined as the time of oil exchange. Áπª‹«Ÿÿ-˜AEı°OE¿oe« "Ò°ı°oeÌ, ´-∞-¿oe«≥ºOEOE-Ê ¶˚∂Ò°°fl«ÓÃ°fl˝oe¬Û ¿oe ≥AEOE ØÊ¿∞ AE ¶°ˆ" ∏OE §AE-£¯¿oe ≥º√°« oeÕμªß-¨∏« ‰∫ÃıÎ«Ì÷Ÿ.

“…Therefore, the reasonable replace of lubricant oil with efficient and economic method is considered urgent. Many researchers focused their attention to investigate the performance of the used oils with the conventional technologies and analyze the deterioration process and the failure mechanism of lubricant oils [2] [3]. Lubricant oils in gearbox of heavy duty truck are exposed to depend on the operating conditions, the fuel quality, the ambient conditions and operating parameters.…”

In the present paper, we have investigated the tribological properties and microstructure of the used gear oil theoretically and experimentally. The deterioration process of the in-service gear lubricant oils was also discussed. The viscosity and microstructure of oils running different mileages were analyzed by viscometer and Fourier Transform Infrared Spectroscopy (FTIR), respectively. In addition, the friction and wear behaviors of the friction pair of the GCr15 steel ball and disc were investigated using a ball on disc tribometer under different mileages' gear oils lubrication conditions. These techniques give reproducible and reliable data with which to evaluate the severity of deterioration process of oils. The objective of this work is to understand the deterioration process of gear oil and analyze the influence of deterioration on the performance and microstructure of lubricant oils used in gear box. Possible explanations of deterioration process as well as its influence on friction and wear behaviors are also discussed. The results reveals the tribological properties of used oils depended on strongly the microstructure and its deterioration process of oil.
