Description

The invention relates to railway transport and relates to the design of the traction and energy section, designed for energy supply and transportation of crushed stone and other machines.

A known cooling system for vehicle assemblies containing exhaust manifolds of internal combustion engines, cooler cavities communicating with the atmosphere and the engine room through an adjustable damper. Air pumped by the fan of the cooling device through the pipeline enters the unit and is discharged into the engine room or into the atmosphere / 1 /.

The disadvantage of this design is the unreliability of the locomotive with this cooling system due to insufficient ventilation.

The most famous is a single-section diesel locomotive M62 with a carriage-type body, containing a diesel generator set, a cooling device with a fan wheel isolated from the living space, a brake compressor operating from the generator shaft, a body ventilation system with a fan, which sucks air from the leaky body of the locomotive /.

The disadvantage of this design is the unreliability of the locomotive due to the insufficiently efficient operation of the body ventilation system. The use of a body fan for suctioning air from the diesel compartment, the location of the air discharge hatch on the front of the diesel engine, the absence of windows for air intake, the small cross-sectional area of the air discharge hatch do not make it possible to provide heat removal from the surface of the diesel generator set and the diesel compartment as a whole , which leads to a decrease in the service life of the equipment and does not contribute to the creation of the necessary microclimate for the staff. The disadvantages of this design are the use of a body fan, which requires additional power taken from the generator, which can be used to increase the traction of the locomotive, and the location of the fuel tank under the locomotive frame, which will require the use of heat exchangers for heating fuel in winter.

The basis of the invention is the solution of the problem: improving the reliability of the equipment of the traction and energy section by creating the effect of suction of additional air by the fans of the generator and the cooling device and creating a microclimate that meets the performance requirements for appliances and power equipment, as well as maintenance personnel, increasing the efficiency of the traction -energy section through the use of less power for auxiliary needs, reducing the overall size ty by the arrangement of the necessary equipment on the frame of limited length and cheaper products due to installation of the cooling device in the body without thermal insulation.

This is achieved due to the fact that the traction and energy section, containing a frame with a body mounted on it, a diesel engine with a flanged generator, above which there is a dump hatch, a cooling device, a brake compressor, a fuel tank, a body ventilation system, diesel engine air filters, has body with windows for air intake located in the rear of the generator and diesel engine and an additional discharge hatch located above the cooling device, made in the form of at least one radi unit, while the discharge hatches are at a distance of not less than the height of the cross-section of the window for air intake from the exhaust manifolds of the diesel engine and the cooling device, and the total cross-sectional area of the discharge hatches is at least half the cross-sectional area of one of the windows for air intake, and the cooling device with fan located opposite the brake compressor and the supply tank.

In the second embodiment, to solve this problem, in the traction and energy section, containing a frame with a body mounted on it, a diesel engine with a flanged generator on an intermediate frame, a cooling device, over which a dump hatch is located, air filters of the diesel compartment, a cooling device is made in the form of at least one autonomous radiator unit and is connected to the air duct, and the body is equipped with windows for air intake with diesel filters installed on them located in the tail of the gene engine and diesel engine, and an additional dump hatch located above the brake compressor, and the dump hatch of the diesel compartment is located at a distance of at least the height of the cross-section of the window for air intake, and the total cross-sectional area of the dump hatch is at least half of the cross-sectional area of one of the brake windows the compressor and fuel tank are located behind the generator and diesel.

The implementation of the cooling device in the form of at least one autonomous radiator unit with a fan allows you to place the necessary equipment on a frame of limited length and its location under the second discharge hatch in the first embodiment and on the intermediate frame in the second version allows heat to be removed from the external hot surfaces of the power plant and brake compressor .

The introduction of air intake windows located in the rear of the generator and diesel engine contributes to more efficient ventilation of the power compartment.

The location of the discharge hatches at a distance of not less than the height of the cross-section of the air intake window from the diesel engine and the cooling device, as well as the total cross-sectional area of the air discharge hatches, which is at least half the cross-sectional area of one of the air intake windows, provides a smoother movement without swirl and loss air through the discharge hatches and the necessary addition of air for partial opening of the air intake windows with heavy rain or snow.

When starting and running diesel 5, combustion air is taken from the environment. At the same time, air intake from the environment is carried out using the generator fan 8.

Diesel 5 with flanged generator 4 is heated to a certain temperature. After that, the fans of the cooling device 7 begin to work.

The heat released in the diesel 5 is removed by the cooling fluid in the radiator sections of the cooling device 7, the exhaust gases through the exhaust system, the air covering the temperature-stressed surfaces of the diesel 5 coming through the air intake windows 15 and cleaned in the filters 10 located at the tail end generator 4 flanged to diesel 5.

In case of inclement weather: rain, snow, air intake from the environment is carried out using a fan of generator 8, and when the engine is warmed up, fans of the cooling device 7 are additionally activated, through air intake windows 15, open half their cross-sectional area (closed one by one sash on each window), and one or 2 discharge hatches 11, protected from precipitation, thereby preventing the excess rainfall from entering the diesel room and maintaining the microclimate in a state that vletvoryayuschem sanitary standards.

When starting up and running diesel 5, combustion air is taken from the environment, while the cooling device 7 starts to work.

At the same time, air intake from the environment is carried out using the fan of the generator 8 and the fan of the cooling device 7.

The heat released in the diesel 5 is removed by the cooling fluid in the radiator sections of the cooling device 7, the exhaust gases through the exhaust system, the air covering the temperature-stressed surfaces of the diesel 5 coming through the air intake windows 17, cleaned in the filters 10 located at the tail end a generator flanged to a diesel engine.

In case of inclement weather: rain, snow, air intake from the environment is carried out with the help of a generator fan 8 and a cooling device fan 7 through air intake windows 17 that are open for half their cross-sectional area (one leaf is closed on each window), and one or two discharge hatches 11, protected from atmospheric precipitation, thereby preventing the excess rainfall from entering the diesel room and maintaining its microclimate in a state that meets sanitary standards.
