1.引言: 内燃机车两组独立的车体通风机分别安装在动力室两侧顶面上,用以将动力室的油气烟雾排出车外。如果车体通风机故障,机械间内不能良好地通风,机械间内油气烟雾的密度会增大,温度会升高,影响柴油机的使用寿命,在炎热的夏季车体通风机故障率更高。车体通风机一旦发生故障,一般需要将其从机车上吊下来,取下风扇,更换电动机,因此检修极不方便。 2.原因分析及危害: 内燃机车在实际应用中,车体通风机故障率较高,主要原因在于它的传动方式不合
1. Introduction: Two independent sets of internal combustion engine vehicle body fans are mounted on the top of the power chamber on both sides, used to power chamber of the gas smoke out of the car. If the vehicle body fan failure, the mechanical room can not be well ventilated, the density of mechanical and electrical oil vapor fog will increase, the temperature will increase, affecting the life of the diesel engine in the hot summer car body fan failure rate higher. Car body fan in the event of failure, the general need to be suspended from the locomotive, remove the fan, replace the motor, so overhauling extremely inconvenient. 2. Analysis of the causes and hazards: In the practical application of diesel locomotives, the high failure rate of the vehicle body ventilator is mainly due to the different driving modes
