Problems solved by technology

However, during the use of this experimental equipment, due to the very high speed and the transmitted torque is very large, a lot of heat will be generated between the various parts, and this experimental equipment is placed inside the factory building, and the heat cannot be discharged and dissipated in time. It will greatly affect the service life of the test bench

Embodiment Construction

[0041] The present invention is described in detail below in conjunction with accompanying drawing:

[0042] The object of the present invention is to provide an air duct system for a reliability test bench of a high-speed EMU drive train, so as to meet the need for timely heat dissipation when the reliability test bench of a high-speed EMU drive train generates a large amount of heat energy. The air duct system of the high-speed EMU power train reliability test bench adopts a reasonable structural design of the heat dissipation channel, and adopts the form of an air-cooled channel with one inlet and multiple outlets to quickly, effectively and targetedly dissipate heat from the test bench equipment, ensuring The concentration of air-cooling energy not only reduces the waste of energy, but also realizes the timely cooling of the test bench equipment.

[0043] refer to figure 1 , the air duct system of the high-speed EMU drive train reliability test bench is composed of an air...

Abstract

The invention discloses an air duct system of a reliability test bed for a drive line of a high-speed motor train unit, aiming at solving the problem that the service life of the test bed is greatly influenced when heat cannot be exhausted and dissipated timely. The air duct system of the reliability test bed for the drive line of the high-speed motor train unit comprises an air duct cement foundation (A), a cooling fan system (B), an air inlet cylinder system (C) and an air outlet cylinder system (D). The air inlet cylinder system (C) is fixedly arranged on the right end of the air duct cement foundation (A) by an air-inlet pre-embedded anchor hook square-shaped plate (h) pre-cast in the air duct cement foundation (A), the cooling air system (B) is arranged on a middle position of the air duct cement foundation (A) by a fan interface fixing frame assembly body (c) and a cooling fan damper assembly body (b) which are pre-cast in the air duct cement foundation (A), and the air outlet cylinder system (D) is arranged on the left end of the air duct cement foundation (A) through an air outlet duct welding plate (k) pre-cast in the air duct cement foundation (A).

Description

technical field [0001] The invention relates to an air duct cooling system, and more specifically, the invention relates to an air duct system of a reliability test bench for a transmission train of a high-speed EMU. Background technique [0002] In recent years, my country's EMU technology has developed rapidly, and the speed has been increased six times, which has greatly improved the speed and efficiency of railway transportation across the country. However, with the increase of the train speed and the intensification of the vehicle axle load, the vibration between the vehicle and the track is intensified, the running stability of the vehicle is reduced, and the safety and operation stability of the train have become increasingly prominent. In particular, the reliability of the drive train, which is the main running part in the train, is greatly impaired. Based on this actual background, we have developed and manufactured a reliability test bench for the high-speed EMU d...
