Avatar of internal combustion engine 'thermometer'

The 'thermometer' 2020 - avatar of internal combustion engine 07 - 16 car speed, load increased, and the impact of the rail and vibration power effect, leading to the left part of the bearing heating bearing wear defect, abnormal heat, light, hot shaft, solid die mechanical damage, affect the normal operation of the train. Or fatigue damage and the hot axle, seriously affect the safety of railway transportation bearing temperature monitoring difficult problem how to break? Trains in the gas turbine engine bearing condition monitoring system to tell you! Diesel locomotive bearing condition monitoring system is a set of complete function, convenient operation, precise and reliable, set the latest display technology, microelectronics technology, data storage and communication technology in the integration of system: 7 inches color screen configuration, implementation of all the measuring accuracy of bearing temperature real-time display; Receive various types of current, voltage and resistance signal, temperature display, records, the limit of the monitoring, report generation, data communication, signal transmitting and accumulated in the flow function, basic error is less than & plusmn; 0. - 5% FS, digital display range 999. From 99 to 1999. 99; On each axle bearing operating temperature automatic monitoring, when a bearing temperature and environmental temperature difference exceeds allowable values of car-body, on-board microcomputer send alarm information, namely guiding the crew check the status of the bearing, avoid such as axle, holding in death of the accident. One, the main research content: the type system to DF4D diesel locomotive shunting bearing working condition based data acquisition, through the composite shaft temperature sensor bearing temperature real-time transmission of information, realize the locomotive bearing temperature real-time display and monitoring. Specific research contents include the following aspects: ( 1) The locomotive bearing working parameters acquisition and transmission; （ 2) On-board data analysis and storage; （ 3) System to automatically filter and bearing abnormal alarm, etc. Second, the composite shaft temperature sensor assembly installed composite shaft temperature sensor assembly is installed on the bearing seat. Composite shaft temperature sensor assembly and the distance from the host is not greater than the range of equipment normal work regulations. Compound sensor assembly installation steps: the axle box outside surface is smooth, compound sensor on the spot welding ( The diagram below) 。 Compound sensor through the internal thread ( The diagram below) 。 Fixed in a composite sensor seat. Four fluorine pad ( The diagram below) Seal damping. Three, application prospect and economic, social and environmental benefits analysis of locomotive transportation safety is particularly important, diesel locomotive diesel locomotive bearing of bearing working condition monitoring technology to achieve the real-time monitoring of temperature, the locomotive driver can view real-time locomotive axle temperature conditions, bearing temperature anomalies in time, guarantee the safety of the locomotive driving. Application of diesel locomotive bearing working condition monitoring technology can achieve real-time diesel locomotive bearing temperature anomaly found that ensure the safety of transportation for improving the safety of railway transportation. （ Source: yanzhou)
