Problems solved by technology
Although increasing the power of each ventilation unit can increase the air intake when the locomotive is running, it will increase the energy consumption of the locomotive and increase the heat generation
At the same time, due to the limited space inside the locomotive, it is difficult to arrange the high-power fan unit, and increasing the power of the fan will also increase the design and manufacture cost of the locomotive

The invention discloses an air input adjusting and controlling method for a locomotive ventilation system. The method comprises the following steps of: when a locomotive runs, detecting the running direction, real-time speed and real-time ventilation pressure value M of the locomotive; and adjusting the opening angle of a shutter guide vane according to the different between the real-time pressure value M and a standard pressure value Q. In the method, the opening angle of the shutter is uniformly controlled together with parameters such as the running direction, speed, ventilation quantity and the like of the locomotive, so that the requirement of every piece of equipment in the locomotive on ventilation is met when the locomotive runs at a high speed.
Description
technical field [0001] The invention relates to railway locomotive technology, in particular to a method for regulating and controlling the intake air volume of a locomotive ventilation system. Background technique [0002] The locomotive mainly draws air from outside the locomotive through the ventilator inside the locomotive or the sunken shutters on the walls on both sides of the machine room to cool transformers (oil), converters (power modules), traction motors and other equipment. The sunken shutter is an integral grid structure, and each part of the grid blade is fixed. As the running speed of the locomotive increases, the air intake at the shutters of the locomotive will decrease instead when it is necessary to increase the ventilation required by the cooling equipment. This is because after the speed of the locomotive increases, with the development of the flow field on the side of the locomotive, the pressure intensity decreases rapidly, and negative pressure will...
