Install the waterproof wave-opening self-ventilated main generator of the internal combustion train under the car

Abstract

The invention relates to a generator, in particular to a waterproof wave-opening self-ventilating main generator installed under the train for an internal combustion train. It solves the problem that the water waves in the open self-ventilated main generator on the power-distributed internal combustion train easily enter the motor through the air inlet and outlet. The outer end surface of the non-drive end cover of the main generator is fixed with an air guide tube, the bottom of the air guide tube is sealed, and the top opening is upward, and the side surface of the air guide tube opposite to the outer end face of the non-drive end cover is opened with The air inlet window facing the first air inlet on the non-drive end cover. A second air inlet is provided on the top of the base near the end cover of the non-drive end, and the second air inlet is covered with an air inlet tube of the base. The bottom of the air outlet on the machine base is fixed with a water baffle to prevent water waves from splashing into the stator through the air outlet. The invention enables the main generator with an open self-ventilating structure to meet the requirement of installing waterproof waves under the vehicle, making it possible to implement it on a power-distributed internal combustion motor vehicle.

Description

Technical field [0001] The present invention relates to a generator, particularly to install waterproof DMU open self ventilated main wave generator for the next car. Background technique [0002] In recent years, with the rise of the DMU, ​​DMU as the main generator of the core components ushered in a good development opportunity. Railcars centralized power and power distributed into two types, a dedicated centralized dynamic drag locomotive, diesel generator and the main frame mounted in an upper drag locomotive, the locomotive is not powered passenger car. Scattered power DMU no dedicated drag locomotive, diesel engine, and a main frame carrying the dispersed generator, the internal space not occupied by passenger load. Power distributed DMU drag locomotive special savings, reduced costs, saving compartment Dora travelers. Therefore, this type of DMU is the future development direction and trends. [0003] Power distributed DMU although the body saves space, but the main gener...
