Capacitor type on-line iron spectrum detector

Abstract

The invention provides a capacitor type on-line iron spectrum detector. The capacitor part of the detector is arranged inside a glass tube filled with a flow liquid, and comprises a first capacitor, a second capacitor and a third capacitor, wherein the first capacitor, the second capacitor and the third capacitor are tightly close to the tube wall of the glass tube, and are sequentially and separatedly arranged. The upper surfaces and the lower surfaces of the first capacitor, the second capacitor and the third capacitor form electrical connections with an analysis circuit through conducting wires of the circuit part. Magnetic fields are arranged on both sides of the glass tube in the directions perpendicular to the surfaces of the first capacitor, the second capacitor and the third capacitor. According to the present invention, for the normal contaminant particles, the normal particle concentration can be indicated; for the wear particles generated due to the fault, the advance warning can be provided so as to remind the maintenance personnel that the further specific analysis is required to perform; the classification detections of the contaminants are achieved, the detection pertinence is improved, and the detection practicality is apparently increased.

Description

technical field [0001] The invention relates to a detection device, in particular to a capacitive online ferrography detector used in the field of oil detection. Background technique [0002] At present, there is a technical solution for measuring the content of metal shavings in lubricating oil with the dielectric constant method, and the feasibility of capacitance measurement is proposed. There are three main methods for detecting the pollution degree of aero-engine lubricating oil used in engineering practice: magnetic plug inspection method, lubricating oil spectroscopic analysis method and lubricating oil ferrographic analysis method. The common disadvantage of these three methods is that they are generally only used for off-line monitoring. There is a magnetic chip detector. Although it can realize online detection, the false alarm rate is high. The reason is that the accumulation of normal abrasive particles will also cause the magnetic chip detector to alarm. The ge...

The common disadvantage of these three methods is that they are generally only used for offline monitoring

Therefore, faults can also be detected when the normal abrasive particle content is high, but the actual situation is not the case, so the detection is not very targeted and the detection results are not accurate
