Introduction to real-time lubricating oil monitoring system development

Introduction of 2019 - real-time lubricating oil monitoring system development 06 - 19 mf engineering training center introduction 'lubricating oil is the blood of the machine. Internal components due to contact with the machinery and equipment ( Bearing gear, etc. ) Relative motion of the wear and lubrication parts to the lubricating oil system, cooling and collect the wear of the debris. To monitor oil and debris analysis can predict or to determine the relative motion component of wear or failure. So the lubricating oil monitoring has been industrial machinery and equipment preventive maintenance and 'as an important part of maintenance. Above: three of the bearing life cycle stage of development the two forms of lubricating oil monitoring lubricating oil monitoring system according to the work form is divided into two kinds: 1, non real-time ( 从- - - - - - 线) Lubricating oil analysis, through the spectrum, iron spectrum and physical and chemical analysis to provide a non real-time but detailed information, is a traditional way to lubricating oil monitoring; 2, real time, 在- - - - - - 线) Lubricating oil monitoring, real-time monitoring bearing gear and other parts of wear and lubricating oil deterioration state to provide information. Has been developing rapidly in recent decades, it has been applied in the following industries: automobile engine, wind turbine gearbox, aviation engine, ship, mining equipment. Real-time lubricating oil monitoring technology in recent years mainly focused on the development of lubricating oil monitoring sensor, according to different technical points 3 kinds: 1, the lubricating oil quality sensors ( 油质量传感器) 2, elements, sensors, 元素传感器) 3, wear debris sensor ( 穿残骸传感器) The aircraft engine lubricating oil real-time monitoring and control system mainly adopts 3 kinds of sensors. Above: the EATON QDM electromagnetic induction type wear debris sensor working characteristics of the aircraft engine bearing aviation gas turbine engine within a variety of high-speed rotating parts ( Rotor, gear and shaft, etc. ) , because of its working condition of high load, changeable, hence the support type of rotating parts now still adopts the traditional rolling bearing. These rolling bearing working conditions are harsh, even with the lubricating oil system to provide lubrication, cooling and cleaning, there is a failure. Bearing from a significant wear and tear to failure may require hundreds or even only a few hours, if not timely was found may cause the internal structure of the seriously damaged when engine is running, lead to stop endangering flight safety, and subsequent high maintenance costs. Real-time lubricating oil ( Clastic) Monitoring can provide timely bearing and gear failure warning and warning, so as to avoid the engine stops seriously damaged or empty. Above: according to the principle of Hertz, bearing the largest stress point is below the surface of 0. 008 to 0. 0012 inches above: bearing clastic sketch real-time used in aeroengine lubricating oil debris monitoring on aviation turbine engines, the wear debris sensor real-time lubricating oil monitoring system of general lubricating oil debris monitoring and control system (for short odm) Or debris monitoring and control system ( DMS） 。 There are many kinds of (debris sensor principle of work Such as the photoelectric effect, electric field, magnetic field, capacitance, ultrasonic, electromagnetic induction, etc. ) Using the electromagnetic induction (generally are, 感应) Principle. The first to use real-time lubricating oil debris monitoring system on civil GE90 engine is a Boeing 777, by the year 1995, it adopted EATON QDM lub oil debris monitoring and control system of the company. Military is the first to use in the U. S. making fighter F119 engine, on the first flight in 1997, its use GASTOPS Canada Metalscan MS1000 lubricating oil debris monitoring and control system. Later in the light of new type engine is equipped with the lubricating oil debris monitoring system, such as: CFM56 - 7 b ( Optional) And GEnx series, the series of LEAP civil turbofan engine. We will through the LEAP - next time 1 b engine by ODMS could further to get to know the composition of typical real-time lubricating oil debris monitoring and control system, work principle and advantages and disadvantages. Above: GASTOPS company Metalscan MS1000 lubricating oil debris monitoring system diagram above: EATON company installed on GE90 QDM lubricating oil debris monitoring and control system in this paper, the resources: 1, Wu TongHai, Progress and trend of sensor technology for on - 线油监测2、伊顿、伊顿宇航石油碎片监测技术3,https://www。 gastops。 com/solutions/aviation/bearing- 和- - - - - - 齿轮- 条件, 显示/
