Problems solved by technology
[0002] At present, the auxiliary engine ventilation system of locomotives does not monitor the auxiliary engine bearings and the ventilation system, and the locomotive depots of the railway bureaus do not maintain and overhaul the auxiliary engine bearing lubrication system and the ventilation filter system on time, which affects the service life of the fan bearings and the ventilation filter system. normal operation
The number of fans in the locomotive is large, and the service life of the fan bearings used for abnormal maintenance is low, which will increase the replacement cost of the bearings; the filter device is not repaired and maintained on time, which will increase the energy consumption of the fans and affect the normal use of the cooled parts; Normal use of locomotives and cost of use and maintenance
[0003] There is no effective device and method for monitoring and reminding system to remind and preliminarily judge the maintenance work of locomotive auxiliary equipment

The invention discloses an auxiliary machine ventilation system monitoring method and a ventilation system for a rail locomotive. The ventilation system comprises a draught fan. An air inlet of the draught fan communicates with a filtering device through an air inlet channel, and an air outlet of the draught fan communicates with a device to be cooled through an air outlet channel. A pressure sensor, an air velocity sensor and a temperature sensor used for detecting the environment temperature are installed on the air inlet channel. A temperature sensor used for detecting the bearing temperature and a vibration sensor are arranged on a bearing of the draught fan. By means of the monitoring method, the running state of the auxiliary machine ventilation system can be monitored in real time, by monitoring the resistance (pressure) situation of the ventilation system, a railway administration can be reminded to carry out washing and maintaining on blockage situations of the ventilation system, by means of the temperature and vibration situations of the bearing of the draught fan, the railway administration can be reminded to carry out overhaul and maintaining on a bearing lubrication system of the draught fan in time, the use and maintenance cost of the draught fan and the energy consumption of an auxiliary machine system are reduced, and the use and maintenance cost of the rail locomotive and the energy consumption of the auxiliary machine system are indirectly reduced.
Description
technical field [0001] The invention relates to an auxiliary engine ventilation system for rail locomotives, in particular to a monitoring method and a ventilation system for an auxiliary engine ventilation system for rail locomotives. Background technique [0002] At present, the auxiliary engine ventilation system of locomotives does not monitor the auxiliary engine bearings and the ventilation system, and the locomotive depots of the railway bureaus do not maintain and overhaul the auxiliary engine bearing lubrication system and the ventilation filter system on time, which affects the service life of the fan bearings and the ventilation filter system. normal operation. The number of fans in the locomotive is large, and the service life of the fan bearings used for abnormal maintenance is low, which will increase the replacement cost of the bearings; the filter device is not repaired and maintained on time, which will increase the energy consumption of the fans and affect ...
