Abstract

The invention relates to an online abrasion particle monitoring system adopting centrifugation, electric shock hammer adsorption and adjacent capacitance. A temperature control module, a magnetizing module, a mechanical centrifugal module, a rotary magnetic field centrifugal module, an adsorption module, an adjacent capacitance particle monitoring module and a demagnetizing module of the system are sequentially connected, wherein an oil inlet is formed in one end of the temperature control module; the adsorption module is a like-pole adjacent type adsorption ring with an electric shock hammer specifically. According to the system, the adjacent capacitance transducer technology based on the capacitance fringe effect is introduced, and non-invasion and unrestraint monitoring of abrasion particles is realized; the abrasion particles in oil are magnetized and aggregated to form large particles through the magnetizing module, the mechanical centrifugal module and the rotary magnetic field centrifugal module, and the large particles move to the vicinity of a tube wall and are adsorbed by the adsorption module, so that the strength of output monitoring signals of adjacent capacitance transducers is improved; by means of a temperature control module and reasonable design of polar plate layer structures of the adjacent capacitance transducers, noise is inhibited, and the overall performance of an adjacent capacitance transducer monitoring device is optimized.

Description

【Technical field】 [0001] The invention relates to an on-line monitoring system for wear particles in hydraulic pipeline oil, in particular to an on-line monitoring system for wear particles using centrifugation, electric hammer 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 Invent...
