Abstract
The invention provides an inductance-capacitance oil pollutant synchronous detection device. The device comprises an excitation-acquisition unit and a detection unit connected with the excitation-acquisition unit through an insulated wire, and the detection unit comprises a capacitance detection unit and an inductance detection unit; the capacitance detection unit comprises a capacitance detection flow channel, and a first left plane coil and a first right plane coil which are oppositely arranged on the two sides of the capacitance detection flow channel; the inductance detection unit comprises an inductance detection flow channel, and a second left plane coil and a right high-permeability magnetic material which are oppositely arranged on the two sides of the inductance detection flow channel, and the inner ring edge of the second left plane coil directly faces the tip end of the right high-permeability magnetic material. According to the technical scheme, the technical problems that an existing oil detection sensor is limited in detection precision and small in detection flux are solved, inductance detection can be achieved, capacitance detection can also be achieved, the high-permeability magnetic material is added on the basis, the signal-to-noise ratio of detected pollutants can be increased, and therefore, the detection precision of the detection device is improved.
Description
technical field [0001] The invention relates to the technical field of oil system fault detection, in particular to an inductance-capacitance oil pollutant synchronous detection device. Background technique [0002] The solid particles in the oil of the mechanical system contain a wealth of tribological information, including composition, shape, size, quantity, etc. This information can reflect the operating conditions of the equipment, and is very important for judging the wear parts, wear types, wear degrees and corrosion degrees of the equipment. has a very important role. Analyzing the tribological information of abrasive particles, and timely replacing abnormally worn mechanisms and contaminated oil can effectively avoid more serious losses. [0003] The current oil detection technology can be divided into two categories: offline detection and online detection. Off-line testing means submitting oil samples to the laboratory for inspection, which has many testing proce...
