Centralized air supply device of railway car equipment compartment and equipment compartment ventilation system

Abstract

The invention relates to a centralized air supply device of a railway car equipment compartment and an equipment compartment ventilation system. The equipment compartment is composed of a apron board, a bottom plate, an end plate and a framework, one or two centralized air supply devices are installed in the equipment compartment, first air inlets and first air outlets are formed in the apron board, an air inlet of the centralized air supply device is communicated with the first air inlets in the apron board, and an air outlet of the centralized air supply device is communicated with the equipment compartment and used for providing cooling air for air-using equipment in the equipment compartment. Inlet air for the air-using equipment in the equipment compartment is extracted in the equipment compartment, the heat radiation and air filtering effects are good, micro-positive pressure in the equipment compartment is guaranteed, the ways that dust and ice snow enter the equipment compartment are reduced, the number of the first air inlets in the apron board is reduced, and manufacturing and maintenance cost is lowered so that cars can run safely in extremely cold, strong sandy wind, high-temperature environments and other severe environments.

Description

technical field [0001] The invention relates to an equipment cabin of a rail vehicle, in particular to a centralized air supply device and a ventilation system for the equipment cabin of a rail vehicle, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] There is usually an equipment cabin under the car body of the rail vehicle, and the equipment under the vehicle is installed in the equipment cabin to protect the equipment under the vehicle from being damaged by stone impact and freezing. Most of the existing equipment compartments adopt a sealed structure composed of skeleton, skirt plate, bottom plate and end plate. Due to the large number of equipment under the vehicle, high integration and high heat generation, especially when operating in a high temperature environment, It is easy to affect the normal operation of the equipment in the cabin due to excessive temperature in the cabin, and in severe cases, it will damage the equ...

Problems solved by technology

Most of the existing equipment compartments adopt a sealed structure composed of skeleton, skirt plate, bottom plate and end plate. Due to the large number of equipment under the vehicle, high integration and high heat generation, especially when operating in a high temperature environment, It is easy to affect the normal operation of the equipment in the cabin due to excessive temperature in the cabin, and in serious cases, it will damage the equipment and affect the normal and safe operation of the vehicle

[0003] In addition, the cleanliness of the air entering the equipment cabin directly affects the service life of the equipment in the cabin, so the air entering the equipment cabin must be finely filtered, especially for rail vehicles operating in high cold, strong wind and sand, and high temperature environments. The existing structure of the equipment cabin can no longer meet the requirements. Each equipment in the existing equipment cabin needs to be air-intaked from the outside of the equipment cabin, resulting in an increase in the probability of sand and dust entering the equipment cabin. When the first air inlet filter efficiency of the equipment cabin skirt plate If the air quality of the equipment is not satisfied, it will seriously affect the normal operation of the equipment. At the same time, because each equipment needs to be fed separately, it is necessary to install a filter that meets the air requirements of the equipment on the skirt board of the equipment warehouse corresponding to each equipment. device, increasing manufacturing and maintenance costs
