Novel on-line monitoring sensor for iron content in oil and monitoring method of novel on-line monitoring sensor

Abstract

The invention relates to a novel on-line monitoring sensor for an iron content in oil and a monitoring method of the novel on-line monitoring sensor. The sensor comprises a detecting pipeline; the inner walls of pipelines at two ports of the detecting pipeline are respectively provided with a first capacitance probe and a second capacitance probe; the first capacitance probe and the second capacitance probe are hollow; the outer walls of the first capacitance probe and the second capacitance probe adapt to the inner wall of the detecting pipeline in shape; and an iron remover and a wiring terminal connected with the first capacitance probe and the second capacitance probe are arranged on the outer wall of the detecting pipeline between the first capacitance probe and the second capacitance probe. The monitoring method of the novel on-line monitoring sensor comprises the following step of: detecting the change of the dielectric constant of the oil before and after iron removal by adopting an electromagnetic iron removal technique and by utilizing the capacitance probes. The novel on-line monitoring sensor has the characteristics of simple structure, low cost, small power consumption and quick response, and the iron content in the running oil can be accurately detected in real time to master a wear condition in mechanical equipment, so as to determine an occasion for halt overhaul.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a novel sensor for on-line monitoring of iron content in oil products and a monitoring method thereof. Background technique [0002] In mechanical equipment, 80% of equipment failures are caused by wear and tear. Equipment wear will lead to the generation of metal iron abrasive particles in the lubricating oil, which will accelerate the aging of the oil. Not only will it fail to lubricate, but it will accelerate the wear and tear of the lubricating system, seriously threatening the safe operation of mechanical equipment. Therefore, how to monitor the wear condition of equipment is very important for the safe and effective operation of mechanical equipment. The iron content in oil provides a direct and reliable information for understanding the wear condition of mechanical equipment. At present, the method of off-line metal content detection of operating oil combined with online...
