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.

The Magnetic Field

The magnetic field effect on the silver deposition pattern generated from Ag +/ Cu redox reaction is simulated with the aid of a biased random walk model. In the model. In the model, one particle that represents an Ag + ion is generated at the same time, and it walks randomly under the influence of a magnetic force. Comparing the simulated pattern with the experimental one, it is confirmed that the convection induced by the magnetic force contributes chiefly to the silver deposition pattern in a high gradient magnetic field.
