Abstract

The invention relates to a monitoring method adopting rotating magnetic-filed centrifuging, adsorbing and proximity capacitance for wear particles. The monitoring method is characterized in that online monitoring of the wear particles is realized by a temperature control module, a magnetization module, a rotating magnetic field centrifugal module, an adsorption module, a proximity capacitance particle monitoring module and a demagnetization module in sequence; an oil inlet is formed in one end of the temperature control module; an oil outlet is formed in one end of the demagnetization module; and the demagnetization module consists of a residual magnetism sensor and a demagnetizer. According to the monitoring method disclosed by the invention, a proximity capacitance sensor technology based on a capacitance edge effect is introduced, and non-intrusive and unconstrained monitoring of the wear particles is realized; the wear particles in the oil are magnetized and polymerized into large particles by magnetizing and mechanical centrifuging, and move near a pipe wall and are adsorbed by the adsorption module, so that the intensity of an output monitoring signal of a proximity capacitance sensor is improved; and by using the temperature control module and reasonably designing the structure of a polar plate layer of the proximity capacitance sensor, noises are inhibited and overall performance of a monitoring device of the proximity capacitance sensor is optimized.

Description

【Technical field】 [0001] The invention relates to an on-line monitoring method for wear particles in hydraulic pipeline oil, in particular to a method for monitoring wear particles using rotating magnetic field centrifugation, adsorption and adjacent capacitors, and belongs to the technical field of hydraulic systems. 【Background technique】 [0002] The wear particles in the hydraulic system oil can not only cause abrasive wear of the kinematic pair, but also hinder the relative movement of the kinematic pair, resulting in malfunction of the control components. Statistics at home and abroad show that 70% of hydraulic machinery failures come from particle pollution of oil. Therefore, on-line monitoring of wear particles in oil has become one of the important ways to reduce wear and hydraulic system failures. [0003] Capacitive sensors are used in the pollution monitoring of machine oil because of their convenient fabrication and low cost. Patent Document 1 (Chinese Inventi...
