[Abstract]:The condition detection of lubricating oil is an important part of ensuring the safe and stable operation of mechanical equipment. Through accurate on-line analysis and monitoring of the condition of lubricating oil, it can monitor the wear of mechanical equipment, predict the occurrence of failure, and carry out maintenance and repair in time. Can greatly reduce maintenance costs, reduce losses, improve production efficiency. Iron and its alloy materials are important components of mechanical equipment parts. When the mechanical parts are worn, ferromagnetic abrasive particles will appear in the lubricating oil path and flow with the oil. Therefore, the wear degree of mechanical equipment can be obtained by detecting ferromagnetic particles in oil to ensure the safety and stability of production. The aim of this paper is to develop a practical ferromagnetic metal particle detector in oil, which adopts the design principle of double excitation reverse inductance sensor. In this paper, the influence parameters of the metal particle detection sensor in oil are studied, and the factors influencing the sensor's detection response are analyzed, and the methods of reducing the error and improving the stability are analyzed. Through simulation software, the finite element two-dimensional axisymmetric model of the sensor is established, and the basic design parameters of the sensor which can produce large output are determined. Then according to the theoretical basis provided by the simulation model, the metal particle detection sensor is designed and manufactured, and the related circuit of the ferromagnetic metal particle detector is designed and manufactured, and the performance of the sensor is verified by experiments. Finally, a data acquisition system based on single chip microcomputer is designed to collect the output of the sensor, and the preliminary research and design of the metal particle detector in oil are completed. Through the preliminary experiment, the metal particle detector can detect more than 100 渭 m ferromagnetic metal particles. The main innovations of this paper are as follows: (1) in the COMSOL simulation experiment, a new "jacket" model, which is different from the traditional "inner clip" basic model, is established, and the new model is compared and studied, and the results of the simulation experiment which are superior to the basic model are obtained. The research innovation of sensor model is obtained, and the basic model and the new model are verified by the simulation results. (2) the AC power supply with adjustable frequency of 2400~3000Hz is designed. As a special exciting power source for sensor. (3) the design of traditional unit gain filter is improved, and the design of bandpass filter with gain is realized. The circuit structure is simplified and good filtering and amplification effect is achieved. (4) A data acquisition system is designed for the project, which combines the sensor with the single-chip microcomputer data acquisition system, and detaches from the measuring instrument (such as oscilloscope, inductance parameter measuring instrument, etc.) Optical instrument), the basic formation of a complete set of instruments.
