Problems solved by technology

Ventilation air ducts are generally assembled and welded with plates. Due to the different shapes of each air duct, the requirements for equipment requiring ventilation and cooling are also different, and the resistance of the pipe network composed of each air duct and equipment is also very different. The air volume and air pressure at the outlet of the duct are uneven, and the air volume of some supply equipment cannot meet the requirements for use, resulting in overheating of the equipment and poor operating conditions
To redistribute the size of the branch air duct, it is necessary to cut the plate and then weld it, which is time-consuming and laborious, and cannot guarantee success

Abstract

The invention discloses an adjustable air passage for locomotives, comprising a main air passage and branched air passages communicated with the main air passage, wherein the main air passage is communicated with a draught fan, and the branched air passages are communicated with equipment needing ventilation. The adjustable air passage for the locomotives is characterized in that each branched air passage is provided with an air flow adjusting device. According to the scheme provided by the invention, for the air flow adjusting device of each branched air passage, the stroke of a translation rod is adjusted by adjusting a nut, a rotating rod drives an adjusting plate to change a vertical inclined angle between the adjusting plate and the branched air passage, thereby adjusting the air flow matching among all branched air passages.

Description

technical field [0001] The invention belongs to the technical field of railway locomotives, in particular to an adjustable air duct for locomotives. Background technique [0002] For the ventilation system of railway locomotives, due to the limitation of the space structure of the locomotive, a common method is to use a fan to ventilate and cool several devices, that is, the outlet of a fan is divided into several branch air ducts, and each branch air duct is respectively and needs to be ventilated. Cooled equipment connections. Ventilation air ducts are generally assembled and welded with plates. Due to the different shapes of each air duct, the requirements for equipment requiring ventilation and cooling are also different, and the resistance of the pipe network composed of each air duct and equipment is also very different. The air volume and air pressure at the duct outlet are uneven, and the air volume of some supply equipment cannot meet the requirements for use, resu...
