“…The intensity of vibration of the system increases with the level of the external particle into the oil; on the other hand, as the size of foreign particles increases, the intensity of vibration first increases and then decreases [50]. An optical ferro-analyzer can be used for online wear derbies analysis and condition monitoring of hydraulic and engine oil [51].Friction is related to the regimes of lubrication. However, its magnitude for a given normally applied load depends on whether the shearing action occurs entirely within the lubricating films or at the solid surface.…”

This article comprehensively reviews the causes of wear of hydraulic components used in hydro-static transmission systems and their remedies by thermal coating processes. The wear of critical components of the hydraulic pump and motors, hydraulic valves, etc., is mainly due to abrasion, erosion, and cavitation. The most commonly found modes of wear in hydraulic components are contamination and abrasion wear. Such wear arresting can be done by using the surface coating and texturing of materials over the wear zones of the damaged parts. This article discusses the causes of wear in hydraulic components and suggests various solutions to reduce such wear. Recent challenges associated with the proposed solution for wear arresting and future scopes are identified in this review. In the end, some novel techniques for the treatment of wear in hydraulic components, such as laser beam treatment, plasma, Tungsten inert gas arc, and Electric discharge coating, have been discussed, which is the potential future work for enhancing the useful life of hydraulic components. These surface treatment methodologies can be applied to alter the surfaces of crucial hydraulic components that experience considerable wear, as seen in hydraulic pumps, valves, and other elements such as hydraulic cylinders.

“…Among them, the three-coil debris sensor is the most widely used due to its simple structure. The sensor is driven by high-frequency voltage, and its recognition accuracy is positively correlated with the frequency of the drive voltage [26]. When the diameter of the oil path increases, the drive voltage frequency must be increased to ensure the recognition accuracy, but this will increase the skin effect of the excitation coil, resulting in an increasing temperature of the sensor, which will affect the alternating magnetic field in the oil path.…”

“…This may change the flow resistance of the original lubricant oil circuit and affect the lubrication effect. Accordingly, one possible solution is to develop a large-diameter debris sensor to match the size of the lubricating oil circuit based on the previously proposed inductive sensor [26]. However, the following problems exist: (a) compared with the small-diameter sensors, after increasing the diameter, it cannot be ignored that the magnetic field strength in the radial direction of the oil pipe is changing; and (b) when the pipe diameter is small, the entire oil pipe is in a strong magnetic field, and all the wear debris passing through the sensor can be detected.…”

Wear is one of the main factors of machine failure. If abnormal wear was not detected in time during the operation of a mechanical system, it probably leads to catastrophic consequences. The wear debris in the lubricating oil circuit contains much information about equipment wear. Consequently, debris detection is regarded as an effective way to detect mechanical faults. In this paper, an inductive debris sensor based on a high-gradient magnetic field is presented for high-throughput lubricating oil circuits. The excitation coil of the sensor is driven by a constant current to generate a high-gradient magnetic field, and the induction coil is wound around the flow path. When wear debris cuts the magnetic line through the flow path, a corresponding induced voltage is generated. The experimental results show that the sensor output signal is linear with the drive current and the wear debris velocity. In addition, the shortest distance between the particles that the sensor output signals can be completely separated is 25 mm. When the distance is smaller, the induced signals are superimposed.

“…Consequently, the characteristics of the debris in the oil provide a reliable indicator of the extent of wear [ 2 ]. The most relevant parameters when assessing wear particles are the size [ 3 ] and mass [ 4 ]. Throughout the operation of a mechanical system, the size and number of abrasive particles increases with wear.…”

Magnetic plug-type abrasive particle sensors have a wide range of applications in oil detection, but there is little literature on the effect of abrasive particle position on detection accuracy. In this paper, an alternating current (AC) bridge-type abrasive particle detection sensor is designed, in which the sensing module utilizes permanent magnets to attract iron particles, and the induction coil is specially designed to detect the magnetic field fluctuation caused by iron particles. A corresponding model was also designed to evaluate the sensor’s sensitivity at different locations. In this paper, the magnetic field distribution of the sensor was first analyzed using finite element analysis software to obtain the magnetic field strength at different positions. Then, the response sensitivity of the sensor to particles and the effect of different positions on the detection results are explored through experiments. The simulation and the experimental results show substantial signal difference signal at different sensor positions. The method outlined in this article can determine the optimal sensing range for subsequent magnetic plug-type abrasive particle detection sensors and subsequently improve their reliability.
